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.

Nutrient management technology is oriented towards better utilization of organic sources that may be available cheaply, along with improving the formulation, time of application and placement of chemical fertilizers so that the nutrient uptake by plants is maximized. Keeping these points in the view, the proposed research entitled “Nutrient management in kharif rice (Oryza sativa L.) through inorganic and organic sources for enhancing productivity and profitability” is planned at Agronomy Farm, College of Agriculture, Dapoli during kharif season of 2018.

A field experiment was conducted on a silty clay loam soil (acidic in reaction and medium in available NPK) during Rabi 2018-19 at Palampur to study the influence of nutrient management practices (Inorganic (RDF), Organic, Natural and Integrated) and varieties (‘Him Palam Alsi-2’, ‘Himani’ and ‘Priyam’) on yield, uptake, quality and soil properties in linseed. Results, revealed that among different nutrient management practices, Integrated Nutrient Management being at par with inorganic practice resulted in significantly higher seed, straw, uptake of NPK and oil yield.

A study was conducted in an ongoing field experiment started during Rabi 1988-89 in calcareous soil at Research Farm of Dr. Rajendra Prasad Central Agricultural University, Pusa, Bihar. The experimental design was split-plot with four fertilizer levels (0, 50, 100 & 150% NPK) in main plots and four levels of manures (no manures, compost @10 t ha-1 , crop residues and compost @10 t ha-1 plus crop residues) in sub-plots.

This study aimed to assess the effectiveness of different fertilizers doses with organic manures on micronutrients availability in turmeric (Curcuma longa L.). A field experiment in completely randomized block design was conducted with eight treatments which were replicated thrice. The eight treatments were comprised of four soil test crop response based treatments along with farmer’s practice, general fertilizer dose, soil test based and absolute control.

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.

The Knowledge of spatial-variability is critical for site specific nutrient management in soil fertility. Soil sample (149) were gotten from surface from 10 selected sites for preparing precise digital maps using point, line and polygon tools of the GIS (TNTmips 2010) software. Soil spatial variability typically defines variation in soil properties in surface soil such as fertility, pH, EC, soil organic carbon (OC), free CaCO3, mineralizable N,P2O5, K2O and S.

The field experiment was conducted the year 2014-2015 on the old long-term fertilizer experiment started since 1983 to assess characterization of humus in soil and it’s relation with physical and physic-chemical properties of soil under the long – term effect of integrated nutrient management in sorghum wheat cropping system. The study showed that there was fraction of humus tended to decrease with depth and use of organics like subabul and FYM in conjunction with NPK fertilizers exerted a remarkable impact on the distribution and built up of humus fractions in soil.

The low yield of pulses is mainly attributed to their cultivation on poor soils with inadequate and imbalanced nutrient application without the application of organic manures and micronutrients like boron, zinc and iron. Since the poor soils are low in organic matter content, use of organic manures plays a vital role in improving soil physical condition, provides vital plant nutrients and maintains long term productivity of the soil. Boron helps in carbohydrate transport. It is necessary for the germination of pollen, formation of flowers and fruits and for the absorption of cations.
