Feasibility of Late Transplanted Summer Pearl Millet for Prolonged rabi Season With Integrated Nitrogen Management Under Indian Coastal Region


Abstract


Experiments were conducted in coastal South Gujarat region of India to evaluate the feasibility of late transplanted summer pearl millet under prolonged rabi season with integrated nitrogen management (INM) during 2014, 2015 and 2016. INM treatments were consisted of four combinations of biocompost and inorganic nitrogen fertilizers. Two planting methods were evaluated, namely drilling and transplanting. Premature heading in transplanted pearl millet was observed up to 8-10% population during all the three experimental years, the possible causes for this are slow nitrogen availability, weather conditions, the thickness of the seedlings, root pruning and seedling age at transplanting. Application of 100% Recommended Dose of Fertilizer (RDF) + 5 t biocompost had significantly increased growth, yield (3862 kg ha-1), benefit-cost ratio (B:C ratio) (3.52) and quality of parameters of pearl millet followed by 75% Recommended Dose of Nitrogen (RDN) + 25% RDN through biocompost. Late transplanted summer pearl millet was little feasible to grow over timely drilled pearl millet as it had reduced pearl millet grain yield by 6.07% and also reduced the net profit by 72.46 US $ ha-1. However, overall, it was feasible to grow late transplanted pearl millet and gave yield up to 3150 kg ha-1 in prolonged rabi season condition for brining summer season well in time.
