Sickle: Used for cutting grass, fodder and harvesting crop. Sickle made of steel is better and lasts longer.

Purpose- Burnt porous clay or cement or plastic pots are commonly used for various purposes in horticulture. The pots are used in propagation or plants, cultivation of ornamental plants and flowering annuals. Growing of plants in pots in referred as pot-culture. In pot-culture, operations such as potting, shifting and filling of pots are very important. Potting refers to planting of plants in pots containing soil mixture, while shifting means removal of plants from pots and planting them again in the same or different pot. Plants growing for more than one year in the same pot need shifting. The time for potting and shifting of plants is monsoon season (July to Sept.) and during spring (Feb-March).

Materials and Equipments-Flower pots, crocks (broken pieces of pots), potting mixture, khurpi and watering can (with fine nozzle).

Purpose-There are several planting plans or systems which can be adopted for planting orchard. The following points need to be considered before choosing any system of planting.

1. It should accommodate maximum number of plants per unit area.
2. It should allow sufficient space for the development of each tree.
3. Orchard operation such as ploughing, dusting are easy to perform.

Problem-Prepare of a layout plan of orchard for 10 ha. area which is situated on the highway. The dimension of the orchard is 3:2. Calculate the areas under each crop which will you grow and also write their suitable variety along with their suitable diagram. Also fulfill the following information about orchard

Problem- Prepare a layout plan for establishing on ideal mango orchard near Varanasi city in 2ha area under high density planting. Calculate the number of plants needed for planting and amount of DAP and sulphate of potash heeded or planting. Also mention the name of cultivars for this region under HDP (200:100:200 NPK g/plant)

Purpose: It is important that the plants occupy the same position where the pegs were placed in the field. At the time of planting the tree the peg is removed first followed by pit making to receive the plant. The plant may be with the ball of earth or without the ball of earth. While planting the tree in the pit there is every possibility that plant may not occupy the same position where the pegs were originally placed. In order to overcome this problem planting board is used. Use of a planting board ensures the planting of the plant in the correct position.

Materials and equipments: Spade, khurpi, planting board, wooden pegs and chain.

Purpose: In propagation of fruit plants by any vegetative methods such as cuttings, budding and in to the selection of ‘mother plants” and “bud-wood”. Use of bud-wood or any other propagation material from high yielding, true to-type, disease free trees (mother plant) will ensure uniform behaviour of trees in the orchard. If possible, propagation material from a single source is used.

Bud-wood used for budding purpose from high yielding, true-to-type and disease free trees certified for the above character by a certifying agency is referred as ‘certified bud’

Procedure: By adopting the flow sheet given below, clean scion from healthy, productive plants, can be selected for vegetative propagation.

Purpose-Multiplication of plants by cutting includes stem, root and leaf cuttings. The stem cuttings are of four different types i.e. hard, semi hard, soft wood and herbaceous wood cutting consist in producing new individuals after the piece of stem has been detached from the mother plant and planted in conditions suitable for regeneration to the missing organs. Stem cutting have to develop a new root system as they already have buds to give rise to shoots. Many cells of the cutting are capable of becoming meristematic and thus are able to produce new roots. The success in the stem cutting multiplication depends upon factors such as condition of the mother plants, part of the tree from where the cuttings are made, time of the year, care while planting and after care. Cuttings can be made during monsoon (July-Sept.) and spring (Feb. -March) season when active cell division is taking place.

Purpose: Layering includes several forms of ground and aerial layering (goottie). When rooting is encouraged on the aerial part of a plant after wounding it is known as air layering or goottie or morcottage. When branches running parallel to ground are utilized, then the method is known as ground layering. Layering is the development of root on a stem while it is still attached to the mother plant. The root formation on the stem is stimulated by removing a ring of bark or by making a notch which cause an interruption in the downward movement of carbohydrates and auxins from the leaves and growing shoot tips. The materials accumulate near the points of treatment and helps in rooting. Root formation depends upon continuous moisture supply, good aeration and moderate temperature around the rooting zone. For the same reason the best result are obtained by these methods during monsoon month (July-Sept.) and spring (Feb. -March) from branches 1 to 2 years of age.

i. SHIELD OR ‘T BUDDING

Materials and equipments- Budding knife, tying material and petridis.

Procedure

Operations on the stock- Select healthy, uniform stock plants of about a lead pencil thickeness and about one to one and half years of age. Remove the thorns (if any) and side branches up to a height of 20 to 25 cm from the soil surface. Select a spot at height of about 15 to 20 cm from the soil surface in between two internodes, which is smooth, other than the southern aspect. With the help of a sharp knife make a horizontal cut of about 1.25 to 1.80 cm in length, deep enough to cut bark only. Starting from the centre of the horizontal cut make a vertical cut, deep enough to cut the bark only of about 2.5 to 3.5 cm long making the shape of english letter ’T’. Open the flaps with the help of knife blade or the back of the budding knife.

Purpose-The term ‘Grafting’ includes all forms of grafting and budding. It is the art of joining the part of together in such a manner that they will unite and continue their growth as one plant. A grafted plant consist of two parts a rootstock, also known as understock or stock, and a scion. The part of the graft combination which is to become the upper portion or top and performs the function of flowers production and fruits is known as scion and the part which is lower portion or root which performs the function of fixing itself in the soil, absorbs moisture and nutrient from the soil is known as rootstock.

When the scion part is a small piece of bark containing only one bud the operation is termed as budding, but when the scion part is a branch containing more than one bud, the operation is termed as grafting.

Problem-Recommended dose of N:P:K for bearing mango tree 1.0 Kg N: 0.87 Kg P and 1.66 Kg K annually per plant. Available fertilizers are urea, DAP and MOP for supplying of NPK respectively.

So, for an orchard of 1 hectare area, the total number of plants is 100 if spacing is 10m x 10m

Veneer grafting

It has one striking advantage in using the detached scion sticks for propagation, i.e. the shoot of the mother plant which is to be multiplied can be cut away from the mother plant and taken to the seedling growing in the nursery for grafting. Proper selection of scion is very important for the success of this method. The scion stick ought to be 3 to 4 months old and with some activated bud, either auxiliary or terminal. This is secured by defoliating the scion shoot about a week before the actual operation

This method can be practiced on seedling stocks grown in pots or nursery beds. A slanting cut about 5cm long on one side of scion stock, is given and the bark along with wood is removed, giving an oblique cut. Now a slanting cut on one side of the scion is made, which will just fit with the notch of the stock. The scion is then placed in position in such a way that the cambium rings of both stock and scion come in close contact. It is then wrapped tightly with 1.5cm wide tape of 200-300 gauge alkathene film keeping the terminal ends free. When the scion begins to grow at the top, (after about 3 weeks) the upper part of the stock is removed, thus forcing the buds to grow more rapidly. The plastic wrap is removed after 2-3 months.

The success is more or less the same in the entire scion (2.5 to 10.50 cm in length) but the growth of scion is always more when bigger scions are used.

MAJOR INSECT-PEST OF MANGO

1. Mango hopper (Idioscopus atkinsani, I. niveosparsus, I. clypealis)

This is one of the most serious pests of mango. They are small greenish wedge-shaped insect. They cause serious damage to the crop at the time of flowering and fruiting. Both adult and nymphs suck sap from the tender plant parts, inflorescence, young shoots and panicles. They excrete sugary shirring substance on which shooty moulds develops. Cloudy and humid weather are favourable for their development.

The following special terms are used in grape cultivation:

1. Training: Consists chiefly in giving a shape to the vine to the various forms of support.
2. Pruning: Consists in removing canes, shoots, leaves diseased, unproductive and other vegetative parts of the vine.
3. Thinning: Thinning is the removal of flower cluster, immature fruit cluster or parts of cluster.
4. Shoots: Shoots are the current season’s top vegetative (succulent) growth arising from a bud after pruning.
5. Canes: Canes are the woody matured shoots.

The various systems of training the vines adopted in the vine-growing centres in India are as follows:

1. Head system
2. Bower system
3. Kniffin system
4. Overhead trellis

Growth

Growth means quantitative increase in the planwt body e.g., increases in the length of stem, roots, number of leaves, fresh and dry weight of fruits etc.

Development

It refers to the qualitative changes from the initiation of growth to the death of a plant or plant parts like seed germination, formation of flowers, fruits and seeds, emergence of buds, leaves and falling of leaves and fruits.

Kitchen garden

Growing of vegetable crops in the backyard of residential houses to meet the requirements of the family all the year round. It is most ancient type of vegetable farming. Such type of gardening is practiced in cities where land is the limiting factor. Vegetables can also be grown on the roof of buildings if land is not available.

Aim of kitchen garden

The main aim is a kitchen garden in the maximum output and a continuous supply of vegetables for the table throughout the year.

Problem 1: Prepare a lay-out plan of model kitchen garden for a family having five (5) members. Calculate the total amount of vegetable required per year and area of the same kitchen garden. Give the suitable crop rotation and show by diagrammatic representation.

Ans.: Total amount of vegetables required annually

In tomato seed extraction is the very important operation. Tomato seed can be extracted by following way.

1. Fermentation methods: Red ripe fruits should be picked and crushed in non metallic pots. Profuse foam formation indicates that fermentation is completed. Fermentation of seed material should not be prolonged beyond 72hr to get seed of high germination. Preferably the seed should be washed free of pulp after 48hr require temperature uses.
2. Acid treatment methods: In case of urgency seed may be washed by using 1.0 to 1.5 liters of 35 to 38% concentrated HCL/g tomato fruit pulp. Fermentation is completed in about 30 minutes. Clean seed are obtained by stirring and washing procedure are quickly as possible.
3. Alkali treatment methods: In case Alkalie 10% sodium bicarbonate is mixed in equal volume of pulp or 300 g washing soda dissolve in 4 liter of boiling water is sufficient for 4 liter fruit pulp.
4. Mechanical methods: It is used for large scale operations put the ripe fruits into the mechanical seed extractor for crushing and separation of the seed and gel from the pulp. By acid 0.8% solution of acetic acid for 24hr at or below 21⁰C (1kg seed/10 liter of acetic acid).

Problem: Cost of cultivation depending upon the seed and time. More yields can be obtained during right time of sowing, but net profit is very less due to the glut in the market. We can get more return from early or late sown crop during both the season due to the high cost in the market.

Nursery

An area where the planting materials are raised for sowing or planting in garden or fields, in other words, the nursery industry involves the production and distribution of different kind of planting material.

Some of the vegetables sown directly in the field are Okra, Pea, Cowpea, Frenchbean Dolichosbean, Radish, Carrot, Bottle gourd, Bitter gourd, Ridge gourd, Spongegourd,Ashgourd, Muskmelon, Watermelon, Cucumber, Pumpkin, Roundmelon, Spinachbeet, Spinach, Coriander, Amaranthus, Lettuce, Fenugreek etc. Some vegetables are propagated through vegetative means like Colocasia, Ginger, Garlic, Potato, Sweet potato, Drumstick, Asparagus, Elephant foot, Pointedgourd and Ivygourd. But there are certain vegetables having very small seeds and first sown in the nursery for better care and to combat the main field. Such vegetables are Tomato, Brinjal, Chilli, Capsicum, Broccoli, Endive, Chicory, Cabbage, cauliflower, Khol-Khol, Kale, Parsley, Lettuce etc.

Raising of seedlings in the nursery beds is economic as well as easier to take care of young, tender seedlings against disease, insect pests and weeds. Better combat against biotic stress like bright sun, rains and low temperature and economisation by saving land, labour and capital to fetch higher market price.

Purpose- One of the important operation for horticulture crops is raising of seedlings (vegetable, fruit trees, shrubs and flowering annuals). Seedlings are either directly planted as in the case of some vegetables, flowering annuals, shrubs and trees or may used as root stock as in the case of mango, citrus etc. For healthy and good stand of seedlings proper preparation of nursery beds is essential. Since large number of seedlings are raised in a consideration. The protection of seedlings from pest, diseases, strong sun and wind is very important. These factor will vary if seedlings are raised under Low Tunnel Polyhouse.

Plant growth regulators are organic compounds occurring naturally in plants as well as synthetic, other than nutrients, which in small amounts promote, inhibit or modify any physiological process in plants.

Basically, PGRs are of two types

Restricted pesticides for use

1. Aluminium phosphide Captafol
2. Carbaryl
3. Dieldrin
4. Methyl bromide
5. Ethylene dibromide (EDB)
6. Sodium cyanide
7. Lindane
8. Methyl parathion
9. Monocrotophos
10. Chlorbenzilate

Purpose: This test is conducted to determine the boldness and soundness of the seeds. The weight of a given number of seeds of different varieties or kinds will vary. This variation is due to boldness and soundness of the seeds. The seeds will vary according to the soil fertility, variety and other environmental conditions. Higher the weight of a variety per thousand seeds, better is the variety for cultivation.

Materials and equipments: Scale, balance and seeds.

The different modes of reproduction applied in vegetable crops are

Asexual

In this case the vegetative parts of the plants viz. rhizomes, corms, tubers, bulbs etc whole or part there off are utilized to produce new individuals. The typical examples are potato, sweetpotato, parwal, artichoke, colocasia, zinger, turmeric elephant foot yam, etc. There are some vegetative crops which can be reproduced through bcth vegetative part as well as seed e.g. asparagus.

Improved production technology is an integral part of hybrid seed production technology, which is a very high venture practice. This is because like several factors (climate, availability of parental lines and technical labour etc), success of hybrid seed production also depends on the success of crop management in the hybrid seed production field

A. Concentrated Organic Manures

Problem- Calculate the amount of farm yard manure, urea, single super phosphate and murate of potash for one hectare tomato crop which require 100, 60, 60 kg ha N, P, K respectively. 1/3 quantity of nitrogen should be given through farm yard manure and rest through chemical fertilizers

Important nurseries and seed merchants of Uttar Pradesh

1. Azad Nurseries, Laxmi Gate, Saharanpur.
2. American Seed Store, Ayodhya.
3. Ashoka Seed Farm (Regd.) Darwaja Road, Ayodhya
4. Beiz Nursery, Azmatgarh Palace, Varanasi.
5. Ganesh Bagh Nursery, Kamachchha, Varanasi.
6. Ram Das & Co. Kamachchha, Varanasi.

Important insect-pests of vegetable crops

1. Aphids: (Myzus persicae)

The aphids damage the crop by sucking the cell sap from the leaves as stems. The affected leaves in severe cases curl-up and rolled. The plant may be stunted, wither and die. There are three different species of aphids. They are greenish or black in colour.

Important diseases of vegetable crops

1. Damping off: (Phytophthora parasitica, Pythium sp. Rhizoctomia solani):This is a disease of the seedlings at the nursery stage. Due to the attack of this fungus seedlings rot at the ground level and collaps.

Description of important annuals

A. Winter season annuals (Seeds are sown in Sept.-Oct. and transplanting in Oct.)

Edge plant

Very low growing plants grown only for the purpose of decoration and demarcation and not for screening are known as edging. Live and inert materials used for living of borders flower beds, paths, lawn, shrubbery and herbaceous border are known as edging. Formal edgings are: Bricks, stones, tiles, concrete etc. Informal edging are: Grass verges and crazy paths made up of tiles stones etc.

Lawn

Lawn is a natural green carpet, and it is important feature of a landscape and a garden without a lawn is not considered complete. Lawn is an area of land closed mowed grasses it is primarily developed for aesthetic and recreational purpose. A lawn is an integral part of a garden and landscape besides aesthetic and recreational purpose and several other purposes. Lawn provides a place for taking rest after tiring of the day, holding parties, social functions, passive and active recreation. Distinguishing characteristic of turf grasses is the ability to with stand close mowing and still providing a functional dense healthy ground cover. Lawn is also called as heart of garden. J.B. Olcoth designed first experiment in lawn grass at Monchester in USA in the 19th century. Festuca and Agrostis species were used to make turf (Lawn) during 1880 in U.K. In the early 19th century lawn become wild spread out side of parks golf course. Now a day in many metro cities of India lawn has become a cultural of the passion of many homes.

Purpose-Planting of foliage and flowering trees, shrubs, climbers, annuals, perennials and lawn in a piece of land by adopting certain principles is termed as garden design. The objective of a garden layout by adopting a design to provide recreation, enjoyment and education to the society. Natural flora, religion, topography of land and climatic had played a major role in the development of garden designs. Basically there are two garden designs. In one the plantation of shrubs, trees, climbers etc. and lawns is done by adopting a geometrical design and maintaining bilateral balance whereas, in the other one the plantation is done by taking in account the topography and terrin of land, containing open lawns and cluster of trees. The former is called formal are artificial garden while the later is called as informal or landscape garden.

Herbaceous border

In this system plant are arranged in irregular group of a kind for harmonious are contrasting colour effect, either all flowering at one time or successfully in such a way that those flowering latter should grow up and screen the all ready flowered. The planting of annuals in the border of a plot is called as herbaceous border. When the border is to be viewed from both side tall plant are planted in center followed by medium and dwarf planting in both side. Herbaceous border may include all the herbaceous plant including herbaceous perennial (Flowering and non flowering) bulbous and annuals (see plate 20 & 21).

Shrubbery-An area of cultivated shrubs in a parkor garden is known asshrubbery or any area in the garden fully solely devoted to the shrub plantation is called shrubbery. These shrubs are maintained in formal way therefore require regular training, pruning and clipping. Maintenance of shrubbery is easy and become less costly if planted properly considering following point (See plate 22).

• Selection of hardy shrubs.
• Shrubs having profuse flowering and beautiful foliage.
• Selection of shrub according to soil.
• Shrub having slow growing habit and required less pruning and management.

Standard solution: Standard solution is defined as a solution whose strength is known. e.g. 1 N solution.

Molar solution: Molar solution can be defined as a solution containing the number of moles of a solute (substance) i.e. molecular weight in gram per litre of the solution. e g. Mol. wt. of NaCl 23+35.5 58.5,

So 58.5 g NaCl per 941.5 ml of water= 1 M NaCI solution. Molarity is generally designated by M.

Molal solution: Number of moles of a substance/solute per litre of solvent makes a molal solution. Mobility is generally designated by m.
