Chilli is a very important vegetable crop and has a great demand in the processing industry and export market. Chilli crop is more responsive to fertilizer application. Application of fertilizers in excess not only causes environmental problems but also reduces nutrient use efficiency, increases the cost of production and reduces the benefit-cost ratio.

The human population on the planet is estimated to reach 9 billion by 2050; this requires significant increase of food production to meet the demands. Intensified farming systems have been identified as a viable means to increase grain production. Crop production inputs include carbon investment in the form of energy, for the manufacture and use of farm machinery, synthetic fertilizers, crop protection chemicals such as herbicides, insecticides and fungicides, groundwater irrigation and the direct use of fuel in farm operations.

India has virtual monopoly in pigeonpea production accounting to 90% of world’s total production but the average productivity is relatively low due to terminal moisture stress and the production is not adequate to meet the demand of increasing population. To meet the said demand pigeon pea productivity has to be increased. There is a need for judicious management of available water and plant nutrients through different fertilizers to increase the productivity and to reduce the production costs of pigeonpea.

Continuous use of chemical fertilizers without organic sources poses soil health issues whereas organic manures using alone without inorganics could not be able to fulfill the requirement of high nutrient demanding crops due to the bulk and slow-acting nature of these organic fertilizer sources. However, neither organic fertilizers nor inorganic fertilizers alone can maintain productivity. The major yield limiting factors in crops production in Indian soils are NPS deficiencies.

Azopirillum brasilense is a plant-growth promoting nitrogen-fixing bacteria that is used as bio-fertilizer in agriculture. Since nitrogen fixation has a high-energy demand, the reduction of N2 to NH4 + by nitrogenase occurs only under limiting conditions of NH4 + and O2.

Cotton (Gossypium hirsutum L.) is the most important cash crop and there is a demand for simultaneous increase in the productivity of cotton, edible oilseeds and fodders to fulfil the diversified needs of growing population. For this purpose, cotton-based intercropping seems to be a promising strategy. Short duration legume fodders are potential sources of nutrients during summer especially atmospheric nitrogen fixing which are supplement of inorganic fertilizers.

Cucurbits comprise 117 genera and 825 species. Out of this 30 species of nine genera are used as cultivated plants. Most of the cucurbits viz., cucumber, bottle gourd, ridge gourd, bitter gourd, snake gourd, water melon and muskmelons are monoecious and annul in habit. However plants like pointed gourd, spine gourd, ivy gourd and chow-chow are dioecious and perennials. It is of high market demand with a special delicacy for the people of India and it fetches premium price in the market.

The paper analyses some demographic and socio-economic characteristics associated with the current population ageing process in Vietnam and the needs for care for the elderly. Improved education and living standards allow families to take better care of the elderly. However, for many elderly people, accumulated assets are still not enough to take care of their lives. The proportion of elderly people increases coupled with a decreased rate of fertility, smaller household sizes, and limited level of financial accumulation, etc.

The excess usage of synthetic fertilizers with minimum application of organic inputs results into nutrient deficiencies, deterioration of soil and also causes environment pollution. It also affects the sustainability of agricultural production. Sustainable agricultural production includes the management of soil organic carbon, use of organic manure such as animal manure, green manure, crop residues, and sewage sludge. Since only organic manure cannot fulfill the nutrient demands of agriculture crops, hence integration of fertilizers and organic sources is the need of the hour.

India is facing various challenges in agriculture sector for sustaining soil fertility and food grains production, besides environmental degradation and food security of the country in the event of ever increasing demands of food grains production with limited cultivable land. Cultivable land and maintaining its soil fertility are one of the major tasks which supports about 17.6% of its population and leads to fact that, our natural resources are under considerable strain. Food grains are a major source of energy and are thus are vital for food and nutritional security.

Agriculture is going through a profound revolution worldwide due to increasing world demand for food, higher costs of energy and other inputs, environmental pollution problems, and instability of cropping systems. The importance of plant functioning can be realized from the facts that knowledge of mineral nutrition of plants has opened new vistas for fertilizer practices. The detection of deficiencies and toxicity of particular mineral nutrient element has enabled us to make adequate soil amendments and root nutrient absorption for better plant growth.

Phosphorous is one of the most abundant metallic element found in the earth’s crust and present in soils in both organic and inorganic forms. Though it is present in high concentration, only 0.1% of the total P is available to plant because of poor solubility and its fixation in soil with other metallic elements in the soil such as Ca, Al, Fe to form calcium phosphate, aluminum phosphate and ferrous phosphate and thus becomes unavailable to plants.

Potassium contributes significantly to growth, development, yield, and quality of the crop plants. Application of unbalanced potassium fertilization leads to low productivity and quality of cereals and other crops. Hence, there is an urgent demand to find out the balanced source of potassium fertilizer through utilization of nutrient management approaches. In the current study, we applied farmyard manure (FYM) as an alternative source of potassium fertilization, combination of FYM and muriate of potash (MOP) to show their role on growth, development, yield.

Humanity is facing a major challenge in producing enough food from the limited resources for an additional three billion people by 2050. Moreover, the productivity of agricultural crops is adversely affected due to environmental abiotic and biotic stresses. To meet the global food demand, intensive agriculture has resulted in indiscriminate use of chemical fertilizers and pesticides.
