ABSTRACT

Information Technology includes computers and communication technology along with associated software. I.T. can be defined as the technology of creation, processing, storage, retrieval and transmission of data and information. Transmission of data and information between through local national, regional and global telecommunication channels are not new to us. Computer networks have been the real facilitators of data and information interchange in the individual and corporate levels. LANS and WANS are the good examples of it. Developing countries have a critical stake in how successfully they cope with the trade, environmental, energy, healthy, agricultural, industrial, population and other challenges facing them as they enter the information age. The World is experiencing an explosive growth of IT at the moment. There have been tremendous impacts of I.T. on the trade, commerce and industries of the globe.

ABSTRACT

Information and Communication Technology (ICT) has become one of the basic building blocks of modern society. Young people are the world’s largest resource in development. Forty percent of the world’s population is under 20 years of age while 66 per cent of the total population in the country is below the age of 35 and this youth play very important role in adoption of ICTs. Present study is concerning with Information and Communication Technology, importance of ICTs on youth and rural peoples of our country, the importance of ICTs is not the technology as such, but its enabling function in facilitating enhanced access to information and communication across large distances. It involved development and need of Information and Communication Technology. It also focused on strategies for sustained ICTs growth in India and development ranking of some selected countries. India has been ranked 121^st among 157 countries in terms of progress in the realm of information and communication technology.

ABSTRACT

Marketers make consistent attempts to innovate tools and strategies to overcome the challenges they face in the business arena. Business innovations are broadly classified under two heads, namely Product / Service innovation. Marketers need to design creative solutions to overcome challenges typical of the rural environment such as physical distribution, channel management, promotion and communication. India’s rural markets offer a sea of opportunity. The urban rural split in consumer spending stands at 9: 11, with rural India accounting for 55 percent of private retail consumption. Indeed the market can be tapped with focused attention and strategy. Currently the Indian retail market is estimated at Rs. 13,30,000 crore and almost half of this growing retail market at present lies in rural India, which is a tremendous growth sector that needs to be tapped with care. This paper examines how the corporate sectors with their innovation and creativity tapping the Indian rural market with their retail marketing.

Key words: Innovation, retailing, rural retailing, rural India, creativity

ABSTRACT

India is one of the leading coconuts producing country in the world. Yet, it does not figure in the list of leading exporting countries of desiccated coconut. The study makes an attempt to examine the Economics of production and marketing of desiccated coconut. The study was conducted in Tiptur taluk of Tumkur district. The primary data was collected from the 10 desiccated coconut entrepreneurs from Tipturtaluk of Tumkur district of Karnataka. The study reveals that desiccated coconut units were utilizing 78.9 per cent of their installed capacity. The net return per tonne of coconut processed by desiccated coconut units was lakh Rs. 32.1, lakh Rs.81.1, and lakh Rs. 114.5 in case of small, medium, and large sized units respectively. On an average Rs. 144.01 lakhs was needed for the establishment of desiccated coconut unit. Out of which the investment on land (53.64%) was a major cost followed by machinery (26.15%), building (15.11%), and power installation (5.11%). The break even analysis showed that all categories of units had processed more than breakeven level. The investment made on desiccated coconut units was realized back within 2 to 3 years. The major constraints faced by desiccated coconut units were lack of skilled labor, limited market for desiccated coconut, higher requirement of working capital, and use of obsolete machines. Motivating the entrepreneurs to improve the quality standards, and modernization of desiccated coconut units need to be considered to improve the performance of desiccated coconut sector.

ABSTRACT

India is the second largest producer of vegetables in the world after China with an annual production of 162.19 million tonnes from an area of 9.2 m ha. The requirement of vegetables in the country has increased a lot to meet the nutritional requirement of an estimated 1200 million population expected by 2020-21. Although the productivity levels of vegetables have increased manifold, it would not be sufficient to feed the ever increasing population. Production per unit area of land, time and inputs can be increased by improving efficiency of the rate and extent to which solar energy is harvested for conversion to economic produce. In multiple cropping systems, the possibility of more efficient use of resources like sunlight, nutrient and water per unit area is higher leading to higher production stability. It can be very much successful in high imput requiring crops like vegetables. Intensive cropping involving multi-tiered vegetable crops like pointed gourd + elephant foot yam + cowpea grown on the single piece of land at the same time can generate profits up to Rs 1,30,000 per acre. India ranks first in the youth population. If the energy of these dynamic youth is properly utilized in the field of better agricultural practices, especially vegetable cultivation, it will help improve the national productivity of vegetable crops and generate employment as a whole. Thus, intercropping involving multi-storied/ multi-tier cropping system can serve as well-established practice for sustained supply of vegetables throughout the year through which rural youth can generate high income for sustainable livelihoods and increased per capita income.

ABSTRACT

Agriculture is an important component of Indian economy contributing over 14% to the National GDP and employment to about 52% of the workforce. The small farm families form the backbone of Indian agriculture. The sustainability of small farms needs to be continuously supported with appropriate technologies and also with promoting off farm employment opportunities in the rural sector. The role of KVKs’ in preparing the next generation farmers’ through imparting training to update their knowledge and skills in modern agricultural technologies related to technology assessment; refinement, demonstration and training of extension personnel to orient them in the frontier areas of technology development. Sh. Narender Singh s/o Sh. Jagdish Rai, Graduate, 42 years old youth from Dharania Village came in contact with KVK, Fatehabad in 2008 and got training from this centre. He was motivated to diversify his traditional system of agriculture with integrated farming system of Dairy Farming, Vegetable, Seed production, inter cropping of Guar in cotton. He also used neem cake and bio control agents in poly houses for management of root knot nematode. He is recycling cow dung from the dairy farm and producing bio gas for domestic consumption with the diversification of farming system. The total expenditure was Rs. 5,55,645 and gross return was Rs. 13,63,100. The farmer benefit cost ratio is 2:45.

INTRODUCTION

Livestock is an integral part of agriculture in our country. In the decade, India’s population has grown drastically by 13% to 1.2 billion people. Meeting the nutritional needs of this swiftly growing is a gargantuan challenge. Researchers and young farmers have an important role to play in the India Government strategy to relieve pressure on food resources. The dairy industry is a large and important sector in India. We are the highest milk producers in world and milk is an integral source of nutrition and household income. But per animal production is very low as compared to developed countries. The challenge is to improve production and reproduction of dairy animals. Indian farmers feed their animals with imbalanced ration. Supplementation of mineral and vitamins in feed not only improves health status but also in turn increase the income of dairy farmers. The economic contribution of dairy sector seems to be quite substantial in the agricultural economy as well as in the national economy. Keeping in view the growing importance of dairy sector in the changing national and global economic scenario, the dairy farming vocational training programs are organized in the Extension Center of LUVAS at Jind. To undertake this work, 856 young dairy farmers of the area who have successfully completed dairy farming vocational training programmes during the year 2010 to 2013 were selected for the collection of data.

INTRODUCTION

Backyard poultry production is an age old practice in rural India. Rural poultry farming in India contributes to about 40% of the national egg production. In ancient time poultry birds were reared for different purposes such as for its fighting ability. In old civilization, the cocks are known for their morning alarm and the selection is also done for these traits. Their fighting ability is more responsible for their spread than there nutritive value of the chickens. Backyard poultry farming is now gaining considerable momentum in the country and enables rural community to participate, in the economic, political and social sustainable development of the rural communities.

Backyard poultry farming is being recognized as important component of socio- economic improvement among the weaker section of society; specially rural youth, landless labour, small and marginal farmers. Backyard poultry generates self-employment, provides supplementary income with protein rich food at relatively low cost. Backyard poultry farming is the one among different enterprises in the present situation which gives some assured income to rural youths of the country. Before 1950, poultry keeping in India was largely a backyard venture. During last 3-4 decades Indian poultry industry has shown excellent growth. Poultry farming is a profitable venture as a means of livelihood and income prosperity for rural youth and farmers. The small and marginal farmers may choose backyard poultry farming alternative method for generating good income with their limited land and water use. Keeping in view of demand of poultry eggs and meat in the country and its potential for income and employment generation among rural youth, there is a need to increase the poultry production in the country.

ABSTRACT

Hydroponics is a plant growth system that provides a more precise control of growth media composition. It offers people the ability to grow food in places where traditional agriculture simply isn’t possible. As Fiji has a warm tropical climate, the development of the tropical fruit and vegetable industry through hydroponics farming to meet local consumption and export market is a lucrative opportunity. The potential for hydroponics farming is enormous and is in demand to sustain production at reliable and consistent level in Fiji. Potential areas for the setting up of hydroponic farms in Fiji include Savusavu, Nadi, Navua, Sigatoka Valley and Labasa. These areas have established theirlogistical status with the market. A wide range of commodities are grown through hydroponics technology which complements the need to harness the “too hot” and “too wet” weather of tropical Fiji. The pristine environment and availability of resources such as water and other hydroponic farming input are added bonus to establishment of such venture. Hydro nut Hydroponic farming system are constructed as simplest form made of bamboo and coconuts using coconut husk as a growing media and worm casting and humus tea are used as fertilizer. It offers some significant benefits over traditional farming, and as word about these benefits spreads, more people will turn to hydroponics for their agricultural needs. As hydroponics allows produce to be grown locally and requires fewer areas to import their crops, there is a reduction in both price and greenhouse gas emissions due to reduced transportation requirements. This saves time and produces healthier, disease and pest free, lusher plants in about half the time as traditional agriculture farming system.

Now days, in every walk of our life, we deal with a lot of information. It can be for personal use or family matters or for official or business matters. We store, process and retrieve variety of information. Information is basically the collection of various facts, records, statistics, formula or methods, which we use for our official work, for our research or for other use. When all these (information, we keep/ accumulate, for possible future use) are put in an organized manner, we find it convenient to use and easy to remember/ apply. Today, as it is rightly said, information is power; information is our knowledge-strength. It is thus important to organize and manage this knowledge that mostly depends on (and derived from) an information pool.

Abstract

Cloud computing is becoming a technology mature enough for its use in genome research experiments. The use of large datasets, its highly demanding algorithms and the need for sudden computational resources, make large-scale sequencing experiments an attractive test-case for cloud computing. So far I have seen cloud computing demonstrated using R. However, it remains to be seen a rigorous comparison of its performance using a BLAST search and its ability to cope with ever-increasing databases and open source frameworks such as bioperl or bioconductor.

Introduction

The capabilities and effort to collect the geographic data has increased dramatically in the last decade to cope up with the increasing demand for the support of decision making and planning process in the state, national and global level.  From the Government sector, there is a need for spatial data to make quick responses to natural disasters, industrial accidents and environmental crises as actions will be decided based on geography. There is constant pressure to make wise decisions in a more time and cost effective and efficient manner. Accurate and current geospatial data are critical to these decisions.

Abstract

Crop cultivation is a complex process and involves a set of activities like land preparation, planting, pest control, irrigation, nutrient management, harvesting, marketing, etc. Entire cycle of crop production requires multitude of information by the farmers. Despite many efforts over the years to disseminate and transfer agriculture knowledge to the stakeholders, large amounts of expertise and knowledge are still out of reach to most of them. Agriculture knowledge may be contained in the corporate database, or it may reside undocumented inside the brain of the researchers or even stored in locations unknown to the majority of the people in the organization. Large sections of the farming community, particularly the rural folk, do not have access to the huge knowledge base acquired by agricultural universities, extension-centers and businesses. In this respect the main challenge is to find this knowledge and apply it to the decision making process involved in agriculture development.

The main purpose of the immune system is to protect the body from foreign substances, diseases or infections. When the body is exposed to a microbe or a foreign substance (antigen), the body makes some response which is called immune response. The purpose of immune response is to recognize, neutralize and eliminate the antigens from the body. Generally, the term immunogen is also used for antigen. Both, antigen and immunogen are used as synonyms but specifically, they are different from each other.

Abstract

The available data revealed that the area under temperate fruits in Uttaranchal was about 1.4 lakh ha, which was more than 60 per cent of total area under fruit crops, whereas the production per annum was to the tune of 44.50 per cent  of the total fruit production in the state. The productivity status of apple (1.38 t/ha) was very low as compared to national average productivity of 4.98 t/ha. Unfortunately, the prevailing constraints such as non-availability of elite planting material; lack of technical know how; dry land horticulture; high cost of production, lack of credit awareness and availability; small and fragmented land holding; old and senile orchard; lack of transport and communication facilities; poor mechanization; lack of efficient marketing system and post harvest infrastructure do not allow the farmers to take advantage of the emerging opportunities in temperate fruit production.

Abstract

Paradoxically, on one hand wild relatives of crop plants got utilized as donor parents in developing hybrids and on the other hand got lost due to lack of conservation of practices, thus genetic erosion. And temperate fruit genetic resources are no exception. Over dependence of growers/orchardists on modern high yielding cultivars and all round development led to neglect of valuable genetic resources of fruit crops. Yet, there are scores of examples where wild relatives have been exploited for genetic improvement of temperate fruits and nuts and still there exists a rich plethora of genetic diversity in the Himalayas which remains untapped and underutilized. Through the process of naturalization, several  elite genotypes, often referred to as geographical/ecological races and biotypes have emerged possessing unique characteristics valuable from horticultural point of view.

Abstract

India has now become the largest producer of fruits after China by producing 45.2 million tones of fruits from 3.78 million hectare area (NHB, 2004). India is first in the production of mango, banana, sapota and acid lime. India has also recorded highest productivity in grapes, sapota and acid lime in the world. India produces about 40 fruits commercially; however, the major share is from tropical and subtropical fruits like mango (28.17%), banana (29.43%), citrus (15.56 %), guava (3.97%) and grapes (2.76 %). Among temperate fruits apple has maximum area and production and 2. 98 % share in total production. Temperate fruits growing in India spread over some 18 states. These states are categorized into 3 major regions, namely, Northern Western Himalayan Region (NWHR), North Eastern Himalayan Region (NEHR) and other hilly areas.

Abstract

Genetic analysis of yield and yield components in tomato (Lycopersicon esculentum Mill.) was worked out by using half diallel mating design. The good general combiners observed were Solan Vajr, FT-5 and UHF-265 for plant height; UHF-107 and UHF-260 for days to first picking; Solan Vajr for number of fruits per cluster; FT-5, EC-191536 and UHF-120 for average fruit weight; Solan Vajr, UHF-265 and FT-5 for harvest duration and FT-5 and Solan Vajr for marketable yield per plant. The best three specific combiners for marketable yield per plant were EC-191536 x Solan Vajr, BL-342-1 x FT-5 and UHF-107 x EC-191536. Hayman’s approach revealed non-allelic interaction in the expression of number of fruits per cluster, number of fruits per plant and marketable yield per plant. Preponderance of non-additive gene action was observed with dominance towards tallness, delayed first picking, more fruits per cluster, longer harvest duration and higher marketable yield, while involvement of complimentary epistasis was indicated in the inheritance of average fruit weight and number of fruits per plant.

Abstract

Bioinformatics, an integrated science of biology and informatics is a repository of new emerging dimensions like proteome, genome, drug discovery etc, whose concepts have varied applications in various sciences/areas including agricultural/horticultural sciences. Bioinformatics tools are employed to investigate interactions between different biological systems i.e. gene-gene, protein-protein, gene-protein interactions and this information has tremenduous application in agricultural/horticultural sciences. It is the computer aided  data handling approach to understand the life process precisely. Biological problem require innovative database prospective for gene sequencing (management and alignment), recognition of genes and regulatory elements, protein structure prediction, evolution and phylogenetic studies, etc.

The agroclimatic conditions of Indian Himalayan region are suitable for growing temperate fruit crops like apple, pear, peach, plum, apricot, almond, walnut, pecan nut, kiwi, strawberry, hazelnuts, pistachio nuts and other small fruits. The region is extended over the states of Jammu and Kashmir (J & K), Himachal Pradesh (H.P.)  and Uttaranchal (U.A.) in the north-western Himalayan region and Arunachal Pradesh, Sikkim, hilly areas of Assam, Nagaland, Mizoram, Meghalaya and West Bengal in the north -eastern Himalayan region. Other areas are ooty, Kodai Kanal and Nilgiri hills in Tamil Nadu. Mount Abu in Rajasthan and hilly areas of Punjab. Although, temperate fruit growing areas in India do not fall in the temperate zone, yet the prevailing temperate climatic conditions due to high altitude and nearness to snow covered Himalayas has made the temperate fruit cultivation possible.

Abstract

Deserts cover about one fifth of the earth’s land surface. Most of hot and dry deserts are near the Tropics of Cancer or the Tropics of Capricorn. Cold deserts are near the Arctic part of the word. Deserts are of two types: Hot and Cold. Some of the important among them are given in Table 1. Spread over an approximate area of 74,809sq km, the cold desert area in India covers 12 out of 131 desert blocks. Leh and Kargil districts of Ladakh in Jammu and Kashmir and Lahual and Spiti along with some part of Chamba and Kinnaur districts of Himachal Pradesh comprise this cold desert area (Fig 1). Similarly, their physiographic location and the consequent geomorphic processes shall unfolding in the region lend to this entire region a largely similar texture. In terms of area, the cold desert of Spiti may be too tiny as compared to the seven major cold deserts of the world (Table 1), but in terms of its high mountains, extreme climate and poor economic conditions of the people, it is one of the most scourged areas on the earth. Located in the interior of continents, away from any source of moisture, cold desert manifest resemble ecological verity and biological diversity. Their geographic remoteness and unfriendly climatic conductions greatly constrain economic growth and development. Envirmental degradation, which is on increase, is an additional cause of concern.

Abstract

Experiments on micro irrigation and fertigation system were conducted under four agronomic conditions viz. pot culture, a young conventionally planted apple experimental block, a high density experimental block and a conventionally planted bearing apple orchard. Direct correlation was observed between growth and micro irrigation treatments of 40% and 60% depletion of soil moisture at field capacity (FC); allowing depletion up to 80% of FC was found to be detrimental causing permanent damage and mortality.  Two doses (low and high applied at 10 weekly intervals) of fertigation were tried and were found at par with each other.  In fact, accumulation of N in soil was observed when applied at high dose after the third application whereas in case of applications at low dose a steady high N level was maintained throughout the growing season.  Observations on physiological parameters revealed better performance by the micro irrigated and fertigated trees.  Powdery mildew in apple could also be affective controlled by pesticide delivery through the fertigation system; however, some pesticides were found to affect the growth of the apple trees.  Fertigation has found to reduce fertilizer application by 95% in apple orchards opening further possibilities of reduced chemical pollution in cultivated soils and agricultural produce.

Abstract

Pollination studies in apple (Malus x domestica Borkh) were carried out in ten apple cultivars with three pollinizers. Flowering pattern of all cultivars was observed to be same. Flower number per bud ranged from 5.00 to 5.80. All the cultivars started flowering in the second to third week of March. Full bloom was recorded in 4th week of April and flowering period ranged from 16 to 19 days. Maximum percentage of anthesis was observed in the afternoon (12.00 Noon to 2.00 PM). Maximum percentage of anthesis was found in cv. ‘Hardeman’ (33.91%). Dehiscence was recorded to be highest between 10.0 AM to 12.00 Noon. Cultivar ‘Spurtype Red Delicious’ showed maximum percentage of dehiscence (35.59 %). Pollen viability ranged from 85.13 (Spartan) to 89.24 per cent (Jonadel) in two per cent acetocarmine. Best pollen germination was recorded in 15 per cent sucrose solution after 72 hours. Stigma attained receptivity two days prior to anthesis and remained receptive up to two days after anthesis with peak receptivity on the day of anthesis. Under different modes of pollination, the maximum percentage (over all mean) of fruit set was recorded in open pollination (41.98 %) followed by cross pollination (39.12 %), hand self pollination (0.66 %) and selfing by bagging (0.23 %). Maximum average fruit set was obtained when ‘Jonadel’ was used as pollinizer which was closely followed by ‘Ruspippin’. Cultivar ‘Gala’ and pollinizer ‘Spartan’ set fruit on selfing. Cultivar ‘Arlet’ had maximum fruit retention both under open as well as cross pollination in comparison to other cultivars.

Abstract

The experimental results indicated that the treatments, cultivars and root stocks had expressed significant influence on growth, fruiting, fruit quality and leaf nutrient status of apple. The highest trunk girth (21.22 cm), shoot extension growth (22.77 cm), tree height (223.60 cm) and tree spread (184.20 cm) were recorded under the 2/3 dose of NPK  fertigation during 2003 and 2004.  The maximum yield (12.82 kg/tree), productivity (14.24 MT/ha) and fruit set (64.84%) were recorded in fertigation treatment of 2/3 dose of NPK which was significantly higher than other treatments during 2004 and similar trend was observed in the year 2003.

Abstract

Promalin treatments significantly influenced the fruit set. Maximum per cent fruit set was observed under the split application of promailn 7+7 ppm. Promalin at 10+10 and 15+15 ppm concentrations and single application of 60 ppm also increased the fruit set. Yield efficiency (g/cm²) also increased to the maximum extent by promalin 7+7 ppm treatment. The average fruit length  increased significantly in 30 and 60 ppm promalin treatments, whereas maximum fruit diameter was recorded under 15 ppm treatment. The most striking effect of promalin was in improving fruit shape measured in terms of length/ diameter ratio(L/D ratio) and calyx lobe length. The maximum increase was observed under 60 ppm treatment closely followed by 30 ppm and 15+15 ppm split application of promalin. No significant effects of promalin treatments were observed on the return bloom in the following year of application. It can be concluded from the present investigations that promalin application at 60 ppm as a single dose or 15+15 ppm as split dose is useful in improving the fruiting and production of ‘typey’ fruits of Delicious apples when applied at king bloom stage. Promalin treatment is beneficial in improving fruit quality of Delicious apples in the marginal low lying and warmer apple production areas producing flattened fruits instead of oblong conical apple fruits.

Abstract

Dual inoculation of Rhizobium + VAM coupled with recommended NPK doses was found to produce the highest bean pod (6.38, 6.40 qha-1) and straw (35.11,35.35 qha-1) dry matter production and resulted in higher macro and micronutrient contents in bean leaves which were to the tune of 4.05, 4.06%N,0.44, 0.49 %P, 2.65, 2.66 %K, 2.65, 2.67%Ca, 64.67, 64.59 ppm Zn, 242, 242.2 ppm Fe, and 36, 36.33 ppm Mn. Under this treatment increase in bean pod and straw dry matter production during the years 2002 and 2003 was to the tune of 130, 131 and 81, 83 per cent, respectively over control.

Abstract

Field experiment was conducted to investigate the effect of different mulches and herbicides (oxadiazon, metribuzin, alachlor, oxyfluorfen, atrazine, pendimethalin) on growth, yield and quality of strawberry. Black polythene mulch significantly increased plant height (23.39 and 25.53 cm), number of leaves (23.67 and 25.00), leaf area (119.33 and 125.16 cm²), number of runners (17.67 and 19.33) and number of crowns (4.67 and 5.00) followed by bicoloured polythene mulch, grass mulch, pine needles and pendimethalin 2.0 kg ha-1 as compared to hand weeding during both the years of study. Black polythene mulch produced significantly higher yield (62.19 and 77.16 q ha^-1) having large size fruits with lower acidity and higher TSS, sugars, ascorbic acid, soluble proteins, total phenols and anthocyanin content. 

Abstract

Foliar N and P content of olive trees have shown a gradual increase from the month of October till May. But gradual decrease in leaf K content occurred between the months of October to February, where after a gradual but continuous increase in its content was noted till the month of May. However, foliar Ca and Mg contents also registered an increase between the months of October to January, but thereafter, a continuous decrease in their content was evident till the month of May. Relatively higher N, P and K contents were estimated during non- cropped year as compared to the cropped year. But converse was true for Ca and Mg content. Among different cultivars maximum values of foliar N, P, K, Ca and Mg were found in Frantoio, followed by Leccino, while minimum values of leaf macronutrients were recorded in Ascolano. Thus maximum values of leaf N, P, K, Ca, Mg ensured regular bearing behaviour of the cultivar whereas deficiencies of these nutrients tended to induce erratic bearing behavior of the cultivar.

Abstract

The present study of effect of drip irrigation and rootstocks on apple cvs Red Fuji and scarlet Gala under high density plantation was taken up at Horticultural Research Station, Seobagh, Kullu (HP) during 2002-2004. Six year old plants grafted on clonal rootstocks viz., EMLA-106, EMLA-7 and EMLA-111 planted at 3x3m were taken for studies. Five levels of irrigation at 100% ETC, 80% ETC, 60% ETC, 40% ETC and basin irrigation at 100 ETc levels were applied through drips starting from March to fruit maturity. Each treatment was replicated four times with one tree in each in a split plot design. Fertilizer application and cultural practices were carried out as per the recommendations of the university. The data on yield, fruit quality and water use efficiency were collected and subjected to statistical analysis. The fruit firmness, TSS, titratable acidity, reducing sugars, total sugar and non-reducing sugars content decreased with increase in the volume applied through drip. There is a little difference among the varieties and rootstocks for biochemical parameters. Various physical quality parameters were significantly improved by drip irrigation over basin irrigation. The fruits of both the varieties had maximum length, diameter and weight on the rootstock EMLA-106. Similarly yield was also influenced by various levels of irrigation.  Drip irrigation at 40% ETC resulted in maximum water use efficiency (0.022 to 0.023 kg / plant/liter) in Red Fuji during both the years under study.

Abstract

The temperate fruits have shown a remarkable progress as about 68 per cent of the total area under fruits and about 91 per cent of the total production of the fruits in the State is contributed by these fruits. The economic analysis of secondary data shows the increasing trend of area under fruits, vegetables as well as production of these crops in the State over a period of time.  Although maximum increase has been found during the last about 5 decades in case of fruits (about 236 times) yet production of vegetables has shown an increase of about 83 per cent  during the last about ½ decade. Similarly flower crops cultivation has also been increasing in the State which has been clear from the increasing number of flowers growing cooperative societies (48 in no.) in the State along with area  (129 ha) under different flower crops (Anon., 2004-05). More emphasis has been laid on diversification of crops so as to make proper use of limited land and other critical inputs. Economic analysis of primary data has shown benefit-cost ratios of fruits, vegetables and flower crops almost in the same range, i.e. maximum Rs. 4.50:1 to minimum 1.53:1, so with meager holding size, vegetable crops and floriculture have been found to be the best option of diversifying crops along with fruits growing so as to reap better remuneration from use of scarce resources.

Abstract

Propagation in vitro using shoot tips / axillary buds has been applied successfully for production of  clonal apple rootstock  Malling 7 of EMLA series. For surface sterilization, HgCl₂ was found to be a good disinfectant as compared to sodium hypochlorite. Shoot tips were established best in MS medium supplemented with 2 mg/l  BA, 0.5 mg/l GA₃ and  0.1 mg/l IBA. Antioxidants were added to overcome phenol exudation. Shoot multiplication was influenced by cytokinin type and concentration. Of the cytokinins tested, BA (0.5 mg/l) was found superior to kinetin. Addition of phloroglucinol improved multiplication rate and shoot growth. Among the auxins tested, IBA was found better and roots were readily induced with 1 mg/l IBA. 90-95 per cent plantlets were established successfully in peat containing pots as well as in the field.

Abstract

Wilt of gladiolus caused by Fusarium oxysporum f.sp. gladioli is a serious disease in Himachal Pradesh and disease incidence ranged between 19.0 to 50.5 at different gladiolus growing areas of the state during 2002 and 2003. Soil solarization of the infected field by covering it with transparent  polyethylene mulch (25 µm) for 40 days in summer months (March-April) was found effective to control the pathogen in soil.  Soil solarization resulted in average maximum temperature of 39.9oC in 2002 and 41.4oC in 2003 with an increase of 11.9 and 9.8^ºC, respectively in comparison to unsolarized soil. Increase in the average maximum soil temperature was found lethal to the Fusarium wilt pathogen of gladiolus. Soil solarization for 40 days resulted in significant reduction (84.6 %) in the colony forming units of the pathogen at 5 cm soil depth in comparison to unsolarized control. Soil solarization also resulted in 63 per cent reduction in disease incidence, recorded increase in different growth parameter of crop and also resulted in early flowering of the spikes.

Abstract

Survey conducted in different Lilium growing areas of Himachal Pradesh revealed the incidence of virus diseases between 15 and 95 per cent in different localities. Mild mottling, curling and necrosis of leaves, deformation and virescence of floral bulbs and flowers and reduction in bulb size were the most prominent symptoms observed. The virus isolate was transmissible through sap, bulb and aphid vectors and had a narrow host range. Electron microscopic studies revealed the presence of filamentous flexuous virus particles measuring 640×17-18nm in size.

Abstract

Cut flowers of rose cv. ‘First Red’, with uniform stem length of 45 cm, harvested during different times of the year i.e. March, May and October, were used for standardization of holding solutions to increase the vase life. Harvest-wise pooled averages of two years data (2003-04) revealed that the cut flowers of March and May harvests gave increased flower diameter, more volume of solution consumed, maximum vase-life, reducing sugar and protein content with minimum weight loss when these were held in a solution containing 100 ppm 8-HQC (8-hydroxy quinoline citrate) +1.5 per cent sucrose.

The effects of packaging materials, temperature and dressers on bell pepper (Capsicum annuum, L.) seed storage, at the end of 24 months, revealed maximum test weight (5.15 g) in poly jar x refrigerator x cow dung. Maximum seed germination was observed in polythene bag x refrigerator x thiram. This combination resulted in slow but gradual decrease in germination from 3rd month (95.33%) to 24th month (75.33%). The same combination of treatments also extrapolated maximum SV-I (15-24 months) and  (Seed Vigour)SV-II (18-24 months). Stress test was maximum (50.01%) in poly jar x refrigerator x thiram. Thus, it was inferred that bell-pepper seed germination and vigour can be maintained for 24 months after treating the seeds with thiram, packing in polythene bag and then storing in refrigerator, after harvesting the crop.

Abstract

The effects of packaging materials, temperature and dressers on onion (Allium cepa, L.) seed storage, at the end of 24 months, revealed maximum test weight (3.67 g) in poly jar x refrigerator x cow dung. Maximum seed germination was observed in cloth bag x refrigerator x thiram. Maximum germination of 87.33 per cent at the end of 21 months was recorded in poly bag x room temperature x thiram which declind to 77.33 per cent by the end of 24 months. Similarly (seed vigour) SV-I, SV-II (up to 21 months) and stress test (up to 18 months) were maximum which showed a declining trend after this period. It can be inferred that the onion seed germination and vigour can be maintained for 21 months when packed in poly jar, stored in deep freezer (-20°C) after treating with thiram (0.3%).

The vast livestock population requires proper harvesting of animal by-products to generate income to the farmers and to provide the employment to marginally educated masses. The density of livestock in our country demands atleast one animal by-product processing plant in each fifty kilometer range. Proper utilization of animal by-products will also serve in reduction of environmental pollution through slaughter house. Ultimately image of the meat industry can be enhanced by proper utilization of animal by-products. The proper disposal of animal slaughter house and by-products waste is further necessary to reduce the environmental pollution and to enhancement the livelihood of neighourers.

Polyhydroxyalkanoates (PHAs) are diverse biopolyesters synthesized by many bacteria as carbon and energy reserved materials under unbalanced growth conditions. Sand-dunes have low nutrient contents especially nitrogen (N) and phosphorus (P) thus could harbor potential PHA accumulating bacteria. There is no report of isolation of PHA producing bacteria from the sand-dunes environment.  Sand samples of rhizosphere and non-rhizosphere regions of the coastal sand-dunes were processed on Nutrient Agar and TYG-Agar media for isolation of heterotrophic bacteria.

Production of Indole-3 Acetic acid (IAA) and mineral phosphate solubilization (MPS) are two predominant and direct mechanisms used by plant growth promoting rhizobacterial strains (PGPR). These traits are widespread among bacteria. Moreover, the role of IAA in plant-microbe interactions is diverse varying from pathogenesis to phytostimulation, to its role as a signaling molecule in microorganisms. With the advent of high performance analytics, molecular tools and recombinant methods, it has become feasible to investigate biochemical pathways of bacterial IAA synthesis at the genetic, biochemical and chemical levels. In the current study, we isolated several PGPRs from Western Ghats region, India.  Of all the efficient isolates, Serratia marcescens SM15 emerged as the most efficient PGPR isolate based on in vitro plant growth assays and ability to express PGPR traits.

Microorganisms are diverse group of organisms differing in many ways and range from saprophytic to virulent one. Virulent are pathogenic and harmful to human and animals and can cause latent to per acute disease. Nowadays although treatment is available for most of the diseases, it is better to prevent the disease rather than going for treatment. Development of immunity is the aim of immunization and hence through knowledge of the host parasite interaction, epitope of the microorganisms responsible for the inducing protective immune responses is of pivotal importance.

Abiotic Environment

The physical or abiotic environment includes all those physical and non-living chemical aspects, which exert an influence on living organisms. The abiotic components are soil, water, air and energy from various sources. These provide both habitation and raw material for the synthesis of organic food.

6.1 Biodiversity

Biodiversity means biological diversity. It measures the variety of the earth’s animal, plant and microbial species; of genetic difference within species and of the ecosystems that support the species in its widest. Biodiversity is virtually synonymous with “life on earth”, this word was coined in 1985. Biodiversity is the degree of variety in nature and not nature itself.

To a layman, wasteland is a piece of land, which is lying uninhabited or uncultivated. These lands are also commonly perceived to produce much less than their potential. Depleted of the green cover and productivity, such lands are often in a critical condition. Broadly, wastelands may be defined as land where the production of biomass is less than its optimum ‘productivity. Wasteland also refers to lands, which are economically unproductive, ecologically unstable and subject to environmental deterioration.

In November 1992 a document entitled Warning to Humanity was released, signed by 1500 scientists from around the world, including 99 Nobel laureates, and the Director General of the United Nations Educational, Scientific and Cultural Organization (UNESCO). The document stated that “human beings and the natural world are on a collision course,” which “may so alter the living world that it will be unable to sustain life in the manner that we know.”

The term growth as applied to higher organisms such as animals commonly is concerned with increase in protoplasmic mass and does apply to reproduction or to increase in number. In microbiology the term refers to increase in the number of organisms. Bacteria increase in number by a process of simple binary fission. Each cell increase in size and redivide into two similar cells. Each of the divide cells may in turn divide to become two cells. Each division produces what is termed as new generation of cells, theoretically there are 2,4,8,16,32,64,128,256 cells in the 2,3,4,5,6,7,8,& 9th generation, this is known as logarithmic growth – the population doubles with each successive generation. Under favourable conditions, bacteria produce generation within 15min. Under unfavourable conditions 24 hours of more may be needed for each generation. Generation time for E.coli is 17 to 20 minutes.

The Concept of ‘Clean Milk’ Production

Although milk is nature’s most ideal and perfect single food both for the newborn and the mature human beings, the possibility of it being a source of biological and chemical hazards cannot be excluded. In view of the immense dietary importance of milk, the need for production of safe, clean and wholesome milk is emphasized. The term ‘clean milk’ does not mean milk in which all visible dirt is absent or milk from which it has been removed; rather it does denote raw milk from healthy animals, that has been produced and handled under hygienic conditions; that contains only small number of harmless bacteria and that possesses a good keeping quality without being treated by heat. In other words, the unhygienic production of milk may lead to inferior keeping quality as a result of rapid microbial multiplication under favourable storage conditions apart from serving as a potential health hazard. These microorganisms cause the milk to sour quickly, putrefy and develop undesirable flavours, colour defects, ropiness and bitterness. On the other hand, the pathogenic microorganisms, which may gain entry through various sources, may cause many diseases to the consumers.

The significance of milk in human nutrition is now well established as it is considered as the best, ideal and complete food for all age groups. However, in spite of being so, milk can also serve as a potential vehicle for transmission of some diseases under certain circumstances. Moreover, by virtue of possessing almost all the essential nutritional factors, milk can also serve as an excellent culture and protective medium for certain microorganisms, which may include potential pathogens capable of causing serious health problems to the consumers. In this way, milk may serve not only as a vehicle of transmission of disease causing organisms, but it can also allow these pathogens to grow, multiply and produce certain toxic metabolites, thereby making itself an extremely vulnerable commodity from public health point of view.

Dairy equipment and utensils with which milk and milk products come into contact are the main sources of contamination in the products. By the use of effective equipment cleaning and sterilization methods on routine basis, milk of high bacteriological quality can be consistently produced. In composite milk plant, a variety of equipment and utensils are used. The use of stainless steel for the fabrication of dairy utensils and equipment provide highly polished and hard smooth surface that can be cleaned readily, apart from showing resistance to corrosive action of detergents and bactericidal solutions. Utmost care is taken to avoid dents and scratches, which could be the possible focal points of subsequent contamination. To overcome all these problems aluminium and stainless steel vessels and equipment present an ideal situation.

India

Milk legislation and regulations are designed to prevent fraud and adulteration. But they now cover many factors that affect sanitation and public health. Milk generally is classified into grades according to the care with which it is produced.
