    Effect of integrated nutrient management on productivity, nutrient acquisition and economics of blackgram (Phaseolus mungo L.) in an inceptisol of eastern Uttar Pradesh
    (Agricultural Research Communication Centre, 2018) Manoj Chaudhary; Surendra Singh; Subhash Babu; Mahendra Prasad
    A field experiment was conducted during kharif seasons of 2010 and 2011 to find out the suitable integrated nutrient management (INM) package for successful blackgram production in eastern part of Uttar Pradesh. The results indicates that significantly higher grain (959 kg ha -1 ), stover (2479 kg ha -1 ) and biological (3438 kg ha -1 ) yields and harvest index (27.9%) of blackgram were recorded with the application of soil test based NPK+10 t FYM ha -1 + Rhizobium + 30kg S ha -1 + 1kg Mo ha -1 over rest of the treatments. With regards to economics, soil test based application of NPK + 10t FYM ha -1 + Rhizobium + 30kg S ha -1 + 1kg Mo ha -1 resulted in highest gross returns (44,580 ha -1 ), net returns (26,519 ha -1 ) and benefit: cost ratio (2.27) over other nutritional treatments. Similarly, integration of FYM, NPKSMo with Rhizobium significantly enhances the nitrogen (3.98% and1.55%), phosphorus (0.53% and 0.27%), potassium (2.52% and 3.53%), sulphur (0.39% and 0.31%), and molybdenum (4.25 mg kg -1 and 3.59 mg kg -1 ) contents in grain and stover of blackgram over control, respectively. © 2018, Agricultural Research Communication Centre.

    Production potential, economics and soil fertility status of blackgram (Phaseolus mungo) as influenced by integrated nutrient supply system
    (Agricultural Research Communication Centre, 2019) Manoj Chaudhary; Surendra Singh; Subhash Babu; G.S. Yadav; S.K. Rai; Mahendra Prasad
    A fixed plot field experiment was conducted during two consecutive years (2010-12) at Farm Research, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, to find out the suitable integrated nutrient supply (INS) practice for improving the soil health, yield and profitability of blackgram in Eastern Indo Gangatic plain zone of India. The results indicated that significantly higher grain (948 and 971 kg ha-1), stover (2433 and 2525 kg ha-1), biological (3381and 3496 kg ha-1) yields of blackgram were observed with the application of soil test based NPK+10 t FYM ha-1 + Rhizobium + 30 kg S ha-1 + 1 kg Mo ha-1 over rest of the treatments.With regards to soil fertility after crop harvest, soil test based application of NPK + 10 t FYM ha-1 + Rhizobium + 30 kg S ha-1+ 1 kg Mo ha-1 resulted in the highest soil available N (223 and 228 kg ha 1), P (21.17 and 22 kg ha-1), K (244 and 247.60 kg ha-1), S (19 and 19.78 kg ha-1) and Mo (0.30 and 0.33 mg kg-1) over other INM treatments. Similarly, soil test based application of NPK + 10 t FYM ha-1 + Rhizobium + 30 kg S ha-1+ 1 kg Mo ha-1 recorded maximum gross returns (Rs.38584 and 50576 ha-1), net returns (Rs.20624.52 and 32415.09 ha-1) and benefit: cost ratio (2.15 and 2.78) over other nutritional treatments. Hence, study suggested that grower should follow soil test based application of NPK along with 10 t FYM ha-1 + Rhizobium + 30 kg S ha-1+ 1 kg Mo ha-1 for fetching higher profitability from black gram cultivation in Eastern part of Indo Gangatic plains. © 2019, Agricultural Research Communication Centre.

    Rhizosphere microorganisms towards soil sustainability and nutrient acquisition
    (Springer Singapore, 2017) Mahendra Prasad; Manoj Chaudhary; Mukesh Choudhary; T. Kiran Kumar; Lokesh Kumar Jat
    The importance of soils and its function is conclusive; the soil is a living entity that needs to be improved under sustainable approach. It is apparent that soil biota contributes substantially to effective soil functioning and maintenance of soil sustainability. The increase of food production to meet out the food security demand of an ever-increasing population has been highly dependent on integrated nutrient management input but ignores the potential of bioagents. The significance of rhizosphere microorganism can be enormous as they are able in managing nutrient transformation, nutrient acquisition and use, and thus crop sustainability. The soil sustainability and nutrient use efficiency (NUE) can be enhanced by modification of rhizosphere through the best management approaches such as agronomic practices, nutrient management, use of organic and biofertilizers, and regulation of rhizosphere processes. © 2017, Springer Nature Singapore Pte Ltd.
