Concept

Basic concept of this type of improvement is to accumulate, infuse and improve the frequency of favourable genes in established population. This includes the removal or substitution of an undesirable gene with a counterpart favourable one with the superior performance in a given environment, incorporation of a balanced gene combination for better performance - per se or may be even bringing in a better plant type congenial for better physiological activity and biochemical versatility, resulting in better performance of a population. As per theory of Hayes (1963), most of the commercial varieties/hybrids can be improved in one way or the other for one or more of the agronomic attributes. This is primarily because some of the lines in each hybrid generally excel in comparison with other in their ability to transmit desirable characters to their hybrid progeny and thus provide scope for the improvement of the weak inbred lines of the hybrid to further better its performance. The choice of the particular population improvement technique mainly depends upon the genetic information. Since by and large, population improvement techniques envisage controlled crossing followed by selection and recrossing by further selection. This information is vital. Therefore, before deciding upon the choice of a particular methodology, such information as the type of gene action involved in the expression of attribute under improvement, nature of genetic associations, extent of heritability, various possibilities of genetic manipulations should be available. Some of the procedures, which could be successfully utilized in population improvement of parents used in released hybrid populations, are backcross method of breeding, convergent improvement, gamete selection, technique for the removal of complementary genes and step ladder method of breeding.

To understand IoT “Internet of Things” it is important to understand internet first. Internet is connecting a device to other device anywhere in the world. When two devices are connected with the Internet, they can send and receive all kinds of information such as text, graphics, voice, and video. The high-speed, fiber-optic cables are used, through which the bulk of the Internet data travels. The Internet has revolutionized the communication world. In today’s scenario the internet is an important part for people around the world. The Internet is a global network of billions of electronic devices. The World Wide Web (www) is most widely used part of the Internet.

The “Internet of Things is a potentially integrated part of the ‘Future Internet’. IoT can be defined as a dynamic global network with self - configuring capabilities based on communication protocols where physical and virtual ‘Things’ interact with each other.

The Internet of Things (IoT) is inter-connecting the networks of smart devices. Smart devices may be embedded with vehicles, buildings, or other electronics object with software, sensors, actuators, and network connectivity. Network connectivity enables smart devices to collect and exchange data. The Internet of Things (IoT), also referred to as the Internet of Everything (IoE) which comprises of the web-enabled devices. IoT has its applications in smart city, smart surveillance, automated transportation, smarter energy management systems, water distribution, urban security and environmental monitoring. Agriculture is another new area of IoT application.

Due to advancement in technology the processing power and storage capacity has been increased, in the recent years. At the same time technology is making the devices pervasive, wearable and mobile. Smart devices are fitted with sensors, actuators which enable devices to sense, compute and act intelligently. They are able to exchange information with environment.

3.1 Introduction

Internet of Things (IoT) allows computational devices and sensory support to connect with each other and access services on the Internet. The IoT idea was introduced to connect devices through the Internet and facilitate access to information for users. The potential application of IoT includes agriculture. The aim of this chapter is to explain the role of NodeMCU in the agriculture field. NodeMCU is IoT module which can be used to present the IoT concept as a basis for monitoring and control. The systems used in farm production processes. NodeMCU play a key role, with a focus on their realization by available microcontroller platforms and appropriate sensors. IoT based system provides opportunity to users to monitor and control the process remotely.
