The first section presents the analysis of the data collected in the first phase through the administration of the survey questionnaire (Appendix-I). It deals with a study of the potential of Internet as a communication tool through an account of the Internet usage habits of the two cities followed by a presentation of their perception, attitudes and internet adoption among the people.

Objectives

1. To study the weeds and its control.
2. To study the herbicides, their types, timing and methods of application.

Weed: A wild plant growing where it is not wanted and in competition with cultivated plants.

Or

Weed is such undesirable plant grown in association with crop which snatches major parts of nutrients, water, light, place and CO₂ available to the crop.

Due to tough competition crop suffers adversely and the production is reduced.

Diseases of bladder and urethra are most commonly reported in farm animals than diseases of kidney. Knowledge of the physiology of the urinary secretion
and excretion is required to understand the urinary tract diseases. The functions of kidneys are to excrete the end products of tissue metabolism except CO2
and to maintain homeostasis with respect to fluid and solutes including acid base balance by selective excretion of these substances. The kidney maintains
homeostasis by varying volume of water and the concentration of solutes in the urine.

In grape growing areas in many parts of the world this illness is a very popular disorder. In this disorder, a bold beer is surrounded by shoot berries, and the name of the hen and of the chicken disorder is like a hen, as bold berry and chicken. The fruit has a sour taste. The signs are the death of rising tips, falling leaves and the fragility of new shoots. With the development of interveinal chlorosis between the edges, the leaves may be deformed, and this is particularly evident after fruiting.

There are number of eating type kiwi fruits in world but Actinidia deliciosa Chev, is most common. It was the recently introduced fruit in India. It was origin of China the oval fruits have flavor of gooseberry. It is egg sized, fuzzy, brown skinned green fleshed kiwifruit. Fruit is a berry, where as Actinidia chinenses a yellow fleshed fruits.

Fresh vegetables are essential part of a healthy diet as it is an important source of vitamins, minerals and fibers. The nutritional content of vegetables varies considerably, though generally they contain little protein, fat and varying proportions of vitamins such as Vitamin A, Vitamin K and Vitamin B6, pro- vitamins, dietary minerals and carbohydrates (Woodruff, 1995; Whitaker, 2001).

Abstract

Real-time PCR, also known as qPCR, is a highly sensitive technique used to determine the real-time amplification of a target DNA sequence. However, the presence of secondary structures or spurious amplicons can distort the results. When using SYBR Green chemistry, the features of qPCR primers differ from those of standard endpoint PCR primers. As a result, designing primers for SYBR Green qPCR requires extra caution and attention. This chapter outlines the essential features and conditions for designing qPCR primers, including primer length, melting temperature, GC content, specificity, and avoiding primer-dimer formation.

Foliage plants are grown for attractive branches and leaves. These plants have several benefits such as improving air quality, promoting better mental & physical health and enhancing the aesthetic value of the immediate vicinity. Some of the foliage plants grown in indoor or in the garden are described in this chapter.

Dieffenbachia

Dieffenbachia is a foliage plant with large and showy leaves. This is native to the West Indies. It is a very popular plant grown in the home gardens due to easy maintenance. The beauty of the plant lies in the unique pattern of colour combination of the leaves. The leaves are yellow near the vein, which turns dark green towards the edge. This combination is random and even within the same leaf, different patterns of ribbons and spots of yellow & green are formed. It can be taken up under various light intensity and growing conditions. Dieffenbachia plants grow up to 2.4 meter height with wide leaves of around 50 cm long and 25 cm wide. 

Mango (Mangifera indica Linn.) (Family-Anacardiaceae) is one of the most popular tropical and sub-tropical fruit crops in India and is well known as the “King of Fruits”. Mango is the national fruit of India and Pakistan as well as national tree of Bangladesh. It is cultivated worldwide in 49.46 lakh hectares with a production of 371.20 lakh tonnes. In India, the crop is cultivated in the largest area of 23.12 lakh hectares among all the countries in the world and production is around 150.30 lakh tonnes, contributing 40.48% of the total world production. India exports 59.22 thousand tonnes of mangoes to 40 different countries worldwide, valuing Rs. 162.92 crores (Anonymous, 2019).

Introduction The popular legume crop known as broad beans, or Vicia faba in scientific jargon, is valued for its diversity and nutritional content. Broad beans have a long history that dates back thousands of years, and they have been used extensively in many cuisines and agricultural practises all over the world. With the use of references from reputable sources, this introduction will discuss the traits, cultivation, and health benefits of broad beans. Annual plants in the Fabaceae family, broad beans have a cool growing season. They originate from the Mediterranean region, but due to their resilience to various climatic conditions, they have been grown in numerous locations across the world. With a height of up to one metre, the plants are renowned for their vigorous growth. Large, podded fruits with many seeds or beans are produced by broad bean plants. Broad bean cultivation is a rather simple process

The impact of biotic and abiotic constraints, the machinery revolution, faster access to information, city development, social and economic context, climate changes that affect agricultural products and people's movement from one region to another, population income, new cropping technologies adapted to people's demand for food diversification and supply, technical and genetic progress, the impact of biotic and abiotic constraints, the machinery revolution, faster access to information and city development have all had an impact on agricultural market trends over the last ten years. (Bonciu et al., 2020a, Bonciu et al., 2020b).

Introduction

Robotics is a branch of engineering and science that deals with robot design, construction, operation, and uses. A robot is a machine that is capable of carrying out a complex series of actions autonomously or semi-autonomously, typically programmed by computer software or controlled by remote operators. Robotics technology combines various disciplines such as mechanical engineering, electrical engineering, and computer science to create machines that can interact with the physical world and perform tasks that would otherwise be difficult or impossible for humans to accomplish. The term "robot" was initially brought to public attention by Karel Capek, a Czech writer, in his play Rossum's Universal Robots, which was published in 1920.

Introduction

Impact studies isolate the effect of an intervention by assuring that there is clean comparison between a treatment group that received the intervention and a comparison group that is just the same except that it did not get the intervention.

Impact studies test whether one thing causes another. Just knowing scores have gone up following an intervention doesn’t mean improvement is attributable to that intervention.

The data are generated from an impact study used to identify best practices, to replicate successful programs or policies, and to avoid mistakes that might have negative implications for future projects.

Quantification of DNA is an essential step after its extraction in conjunction with the confirmation of the quality. NanoDrop spectrophometer is a powerful instrument in determining both purity and concentration of nucleic acids on the basis of absorbance values obtained by adding small amount of sample (1-2 μl) on the measurement surface.

Principle: The instrument works on the basic principle of spectrophotometry, which takes highly sensitive fluorescent measurements of the microvolumes. It takes use of microvolume sample retention technology based on surface tension property of the liquid and fibre optic technology. Together, these features make it possible to detect sample even in microlitres, which is much more than the traditional method that need cuvette-sized sample volume. The concentration of nucleic acid sample is normally determined by measuring its absorbance at 260 nm.

The chapter on completely randomized design (CRD) presents an overview of its theoretical principles, structure, and randomization methods. It includes the mathematical modeling of CRD and the analysis of ANOVA tables. Additionally, the chapter facilitates an understanding of how to analyze CRD and factorial CRD data using R, offering valuable practical insights for research applications.

Completely Randomized Design

Completely Randomized Design is a type of experimental design commonly used in statistical analysis and research. It is applied under specific conditions:

• Homogeneous units: CRD is suitable when the experimental units are consistent and uniform across the study area.

• Adherence to experimental design principles: This design conforms to two principal aspects of experimental design i.e. Randomization and Replication.

• Flexibility in replication: It allows for both equal and unequal replication of treatments within the experimental setup.

• Suitable for controlled environments: CRD is particularly effective for experiments conducted in greenhouses or laboratories, where conditions can be tightly regulated

Approaches in Extension

Agricultural extension services have gone through various stages over the years, from the individual farm visits approach to the T&V approach. All these approaches are characterized to a greater or lesser extent, by a “ top- down” planning. Extension approaches mostly determine the direction and nature of the system in terms of structure, leadership, program, methods and techniques, resources, and linkages. Extension approach is a style of action within a system which embodies the philosophy of the system. Although there are many approaches to agricultural extension, there is certain commonality in them. All approaches function through non- formal education and all have agricultural content for the development of rural people.

Ministry- based General Extension

Ministry of Agriculture was entrusted with agricultural extension in a top- down manner for planning for the adoption of technologies. An increase in national production is taken as the measure of success.

All persons engaged in agriculture are the clients of this public extension who are served by extension staff. Program formulation and implementation are guided by public interest. Ministry- based extension faces difficulty in serving the majority of potential clientele and financial constraints that force it to reduce the staff. Whereas extension demands location- specific technologies and flexible decisions, the university extension is mostly top- down in nature. As the approach lacks a two- way approach the messages are not location specific. Production alternatives are absent in this approach.

The Training and Visit Approach (T&V)

Table cream: It is also called coffee cream, single cream or homogenized cream. It is used in coffee and tests about 20% butter fat.

Table oil expeller: It is a type of the machine that is used for extraction of the oil from the oil seeds (Plate 588).

Table ready meat: Cooked and smoked sausages are called table ready meat.

Tal prolong: This wax is esters of fatty acid glycosides NaCMC.

TAME: It stands for p-Toluene sulfonyl L- arginine methyl ester. It is used in isolation of Trypsin inhibitor.

Introduction

Raspberry, scientifically known as Rubus idaeus L., belongs to the family Rosaceae. It is also known as “red raspberry” or “European raspberry,” and its chromosome number is 2n=14. Raspberry is an important and popular fruit crop due to its rich flavor, high nutritional value, and various medicinal properties. Raspberry is rich in vitamins, minerals, dietary fiber, and antioxidants, making it a valuable component of a healthy diet (Rahman et al., 2020). Raspberry is widely used in the food industry for jam, jelly, juice, ice cream, and other processed products.

Origin and Distribution

Raspberry is believed to have originated in Eastern Europe and Western Asia (Farrar, 2016). Raspberry was introduced to India during the British era and was initially cultivated on a small scale in the hilly regions of the country. Today, raspberry cultivation has spread to various parts of India, including Himachal Pradesh, Jammu and Kashmir, Uttarakhand, and Sikkim. The major raspberry-growing states in India are Himachal Pradesh and Jammu and Kashmir.

Fruits, the vivid and delightful offerings of the nature, undergo remarkable transformations as they travel from the orchard to our dining tables. These changes indicate the significance of post-harvest physiology, which is the scientific study that reveals the secrets of how fruits behave after they are picked, including the mechanisms that affect fruit quality and how long it may be stored. The next section provides definitions of the various stages and key players involved in the processes of fruit maturity, ripening, and post harvest physiology. These topics will be further explored in the subsequent sub-sections of this chapter.

Fruit developmental physiology

The life cycle of horticultural commodities (fruits and vegetables) can be effectively categorized into three primary physiological stages after fruit set or initiation, namely growth, maturation, and senescence. Still, a lack of obvious differentiation exists among the several stages. Growth encompasses the process of cell division followed by cell enlargement, which determines the ultimate size of the product. Maturation typically begins prior to the cessation of growth and involves various activities across different commodities. The stages of growth and maturity are commonly denoted as the developmental phase. Senescence can be described as the phase in which anabolic biochemical processes transition into catabolic processes, resulting in the ageing and eventual demise of the tissue. Ripening, a term specifically used for fruit, is typically regarded as the initial phase of senescence that occurs during the later phases of development. Defining the transition from growth to senescence is rather straightforward.
