Objective

1. To know the different types of fertilizer application methods applied in spices and condiments.

Methods of fertilizer application: The different methods of fertilizer application are as follows:

a) Broadcasting

1. It refers to spreading fertilizers uniformly all over the field.
2. Suitable for crops with dense stand, the plant roots permeate the whole volume of the soil, large doses of fertilizers are applied and insoluble phosphatic fertilizers such as rock phosphate are used.

Broadcasting of fertilizers is of two types

1. Broadcasting at sowing or planting (Basal application): The main objectives of broadcasting the fertilizers at sowing time are to uniformly distribute the fertilizer over the entire field and to mix it with soil.

3.1 Introduction

One of the most important functions to the AAS units is to widely disseminate the advisory bulletins among the user community. A unit cannot be considered operational unless its bulletins are reaching the target masses. The dissemination is one way communication which is broadly speaking the process by which human beings share information, knowledge, experience, ideas and motivation. 

There is a high demand for arable land to meet food demand and end malnutrition due to the growth of megacities and the global urban population. To enhance yield per unit area, conventional agricultural practises result in agricultural intensification and land clearing for crop cultivation. It has been established that these behaviours have a negative effect on the ecosystem, including soil and water contamination. It is crucial to take into account the application of vertical farming technology which makes use of both horizontal and vertical space and utilises nutrients, water and time (off-season production with artificial illumination) more efficiently to create a larger yield per unit volume of area than conventional outdoor farming. Since microgreens are rich in phytonutrients and are easily harvested, it is being thought of to grow them utilising cutting-edge vertical farming technology. Forest area being turned over to agriculture causes deforestation, the depletion of natural resources like groundwater, loss of biodiversity due to the destruction of habitats, increased soil erosion and greenhouse gas emissions.

Natural nutrient management in India marks a transition from synthetic fertilizers to sustainable, eco-friendly approaches that focus on improving soil fertility, crop yield, and environmental integrity. Rooted in traditional Indian agricultural wisdom, these practices are regaining importance due to their compatibility with natural farming principles, minimal reliance on external inputs, and enhancement of soil microbial activity.
A key method is the use of Jeevamrut, a fermented culture made using cow dung, cow urine, jaggery, pulse flour, and soil from field bunds. This mixture significantly boosts microbial activity in the soil, facilitating nutrient availability and decomposition of organic matter. It is applied directly to the soil or as a foliar spray and is known for improving nitrogen fixation and phosphorus release.
Ghanjeevamrut, a dry, solid variant of Jeevamrut, is used as a base application before sowing. It delivers a slow release of nutrients and is ideal for areas facing water shortages or crops requiring prolonged nourishment.
Panchagavya, another traditional bio-input, is a blend of five cow-derived products—milk, curd, ghee, urine, and dung—alongside banana, coconut water, jaggery, and water. Used mainly as a growth promoter, Panchagavya enhances germination, root development, and crop immunity, and is often applied as a foliar spray.
Green manuring using legumes such as sunhemp, dhaincha, and cowpea contributes significantly by adding organic nitrogen to the soil. These crops also improve soil aeration, structure, and moisture retention when incorporated into the soil.

Chrysanthemum (Chrysanthemum spp.), popularly known as “mum” or “guldaudi”, is a major commercial ornamental plant grown for cut flowers, loose flowers, and garden display. Belonging to the family Asteraceae, it is valued for its vibrant colors, diverse flower shapes, and long vase life. Chrysanthemum is attacked by several insect and mite pests, affecting both foliage and floral quality, leading to reduced aesthetic and commercial value.
Distribution: Widely distributed in India wherever chrysanthemum and sunflower are grown.
Biology: The eggs are laid singly on the upper surface of leaves, obliquely inserted into the tissue, with opercula appearing as whitish or brown dots. The incubation period for the eggs lasts about 5 to 7 weeks. Following hatching, the nymphs undergo hemimetabolous development (no true pupal stage). The nymphal period spans 2 to 3 weeks, during which the nymphs moult five times before reaching adulthood. Adult insects are approximately 4 mm long, with blackish bodies and lace-like transparent wings (Rizkawati et al., 2023).

Cloud has been defined as a visible aggregation of minute water droplets and / or ice particles in the air, usually above the ground level.

CLASSIFICATION OF CLOUDS

Though confusion apparently arises from the number of kinds or species, the genera seems reasonably clear out, if we are able to recognize their main characteristics.

Clouds are usually classified according to their height and appearance. For convenience, we list them in descending order. High clouds, middle clouds and low clouds are some forms do not fit in any of these categories. But fortunately their particular characteristics make them easily identifiable as vertical development clouds. We must exercise some caution in studying on height. There is some seasonal as well as latitudinal variation and there is some overlapping from time to time. However, the appearance of clouds is quite distinctive for each height category.

It is defined as the reaction of living tissue to injury which begins following a sub-lethal injury to tissues and ends with complete healing. The purpose of inflammation is to destroy and remove the irritant and to repair the damaged tissue. 

Causes
    1.    Pathogenic organisms: Bacteria, virus, fungi, protozan and parasites.
    2.    Chemical poisons: Acid and alkalies. 
    3.    Mechanical or thermal injuries. 
    4.    Immune reaction: Antigen antibody reaction.

NEW CELLS ARE PRODUCED BY DIVISION OF PREVIOUSLY EXISTING CELLS

All cells come from previously existing cells

To make a new cell identical to itself a cell must perform 4 tasks:

It must grow and make additional copies of all its organelles, enzymes, etc..

It must duplicate its DNA

It must accurately separate the DNA into 2 units, so that each cell gets a full set

It must divide into 2 cells (cytokinesis)

Horticultural plants are grown for their produce like fruit, vegetable, flower, medicinal component, spices etc. Therefore, these plants should be managed in such a way that human desires for the purpose of growing them are fully satisfied in terms of quality and quantity of produce. This demands direct manipulation of plant growth itself or plant environment through various inputs. In manipulation of plant development, training and pruning are important for which our knowledge about plant development and its phenology has to be complete. These practices are important in fruit crops.

Properties

1. Bacteroides, Dichelobacter and Fusobacterium are major gram negative anaerobes isolated from human and animals. Other gram negative anaerobes are listed below (Table-1).

2. The bacteria are tolerant to oxygen in comparison to strict anaerobes. The bacteria do not die after oxygen exposure.

3. The bacteria naturally inhabit the intestine and mucosal surfaces of human and animals. Majority of them are opportunistic pathogens. Often they cause mixed bacterial infection along with aerobes. The aerobes remove oxygen and create an anaerobic condition favourable for their growth. The aerobes may also supply other growth requirements. For e.g. Porphyromonas asaccharolytica requires vitamin K for its growth, supplied by another aerobic bacterium, not the host.

4.1 Introduction

The livestock/poultry have great capability for climatic adaptation and acclimatization. However in an open environmental condition their overall well-being and efficiency depends on day-to- day weather conditions. While certain breeds of livestock and poultry are considerably flexible to adjust themselves with the varying weather conditions, the others may have little adjustability. This has led to the development of weather/climate based livestock/ poultry management practices which include the general care. Nutrition and health managements for optimizing conditions for best yield in respect of milk, meat, eggs, wool, load carrying capacity etc. have been properly documented. 

The agricultural sector is undergoing a significant transformation, driven by the advent of digital technologies and smart farming practices.

It delves into the various components of smart farming, including precision agriculture, smart irrigation systems, and automated machinery. The article also examines the benefits and challenges associated with the digital transformation of agriculture, including economic impacts, environmental considerations, and the role of policy and regulation. Through case studies and real-world examples, the article highlights how smart farming is reshaping the agricultural landscape and paving the way for a more sustainable and food-secure future.

Introduction
Generally, muscles and offals obtained from animals feeding on grass and various other cultivated crops are regarded as meat. Apart from the meat obtained from the cattle, sheep, goat, pig and poultry, in many countries particularly Denmark, Belgium, Holland and Germany, horse meat is also consumed (hippophasia) as normal meat. Kangaroos are slaughtered for meat in Australia whereas capybara a large semi-aquatic vegetarian rodent, is used in South America as of one of the meat source. Dog meat (fragrant) is relished (Kinophasia) in few cultures such as South Korea, China, Vietnam and few north eastern states of India.
In many parts of the world including Indian subcontinent, buffalo meat (Bubalus bubalis), also known as water buffalo or arna, is quite popular owing to its tenderness, leanness and low cholesterol qualities. It is distributed in many countries around the world such as India (largest population), Pakistan, China, Bangladesh, Indonesia, Philippines, Hungary, Italy and France etc. Bison (Bison bison) from North America is also called buffalo but they are separate species of the order Bovidae. Rabbits are also source of meat having higher growth rate and better feed conversion ratio (2:1). Elands are another meat source which are raised in Africa and Russia for meat purpose.
Meat is quite high in protein content but the presence of saturated fat is perceived negatively due to its association in various cardiovascular diseases, diabetes etc. Efforts are made to produce lean meat having higher content of unsaturated fatty acids and to reduce the ω-6 to ω -3 fatty acids ratio.

Abstract

This paper illustrates the summary of work by different groups on the potential for agribusiness and marketing research by agricultural economists over the past decade. Methodology to establish research priorities in agribusiness and marketing are reviewed. This review leads to a consideration of the agribusiness research issues including the funding sources, identifying users of agribusiness research, data needs, and limitations of agribusiness research programs. This paper also presents a potpourri of  suggested research initiatives in agribusiness research for agricultural economists. Research in these areas may be difficult for a number of reasons including, decreased reliance on economic theory as the soleparadigm, providing competitive advantage to a single agribusiness firm while balancing public and private needs, funding sources, and data confidentiality. Recommendations for outlets for academic research are presented.

Introduction

Land serves as storage for water and nutrients for plants and other living organisms, but the land resources are limited. India has about 18% of world’s population and 15% of livestock population to be supported from only 2% geographical area and 1.5% of forest and pasture lands (Rao et al., 2015). The per capita availability of agricultural land has declined from 0.48 hectare in 1951 to 0.16 hectare in 1991 and is likely to decline further to 0.08 hectare in 2035. This decline in per capita land availability in the country is mostly on account of rising population (GOI, 2010). 

Objective of the conservation of forage is to preserve as much as of the crop nutrient as possible. However, during ensilage loss of nutrients occurs. There are five sources of loss. Theses are:
 
    (a)    Field losses 
    (b)    Oxidation or respiration losses 
     (c)    Fermentation losses
    (d)    Effluent losses 
    (f)    Aerobic deterioration

Introduction

Indiscriminate use of acaricides not only causes the development of resistance in phytophagous mites but are also harmful to their natural enemies, therefore, poses a serious problem of pest resurgence. Hence, worldwide attention has been focused to utilize the natural biocontrol agents and minimize the use of chemical pesticides for the control of mite pests in agriculture with a view to develop a suitable IPM strategy. Among natural enemies of phytophagous mites, predatory mites have been found to be most effective and efficient tool in IPM programme because of the fact that many of these are not only abundantly available in nature but are also voracious feeders and have proven ability to suppress the pest mite population below economic injury level. Beside this, predatory mite can locate, run and catch hold of the pest mites even the pest mite is hiding in rolled leaves, under webs or even in the galls or erinium, etc. Some of the predatory mites require very low population of pest mites as prey, for their survival and multiplication, which is an added advantage for potential predation. Some predatory mites such as Typhlodromus pyri have good synchronization with the prey mite, Panonychus ulmi as, both hibernate and remain active in orchards.

Answer the followings
    Q.1.    What is mastitis?
    Ans.    It may be defined as inflammation of mammary parenchyma and characterized by physiochemical changes in the milk and pathological changes of the glandular tissue.
    Q.2.    What are the cardinal changes of milk and udder in mastitis?
    Ans.    Changes of milk includes discoloration, presence of clot, and presence of huge leukocytes whereas, mammary gland becomes hot painful swelling and induration.
    Q.3.    What is sub clinical mastitis?
    Ans.    In subclinical mastitis, normally mammary gland is normal by physical examination; however, cellular constitution only indicates presence of mastitis (i.e. increased somatic cell count).
    Q.4.    What is the basis of diagnosis of sub clinical mastitis?
    Ans.    Diagnosis sub clinical mastitis depends largely on indirect tests which are related to leukocyte content of milk.

SEX IS VERY COSTLY

Large amounts of energy required to find a mate and do the mating: specialized structures and behavior required

Intimate contact provides route for infection by parasites (AIDS, syphillis, etc.)

Genetic costs: in sex you pass on only half your genes to your children

Males are an expensive luxury- in most species they contribute little to rearing offspring

But There are Some Advantages

More genetic diversity: more potential for survival of species when environmental conditions change

Shuffling of genes in meiosis (random separation of homologous chromosomes)

Crossing-over in meiosis (see below)

Fertilization (genes from 2 individuals brought together)
