Abstract

Chemical fertilizers are one of the costliest input for pearl millet cultivation and also its imbalanced usage results in deficiency of macro and micro nutrients, soil health and finally yield reduction. Considering this issue a field experiment was conducted to study the effect of different sources of nitrogen on the productivity of pearl millet (Pennisetum glaucum). The experiment was conducted at Agricultural College Farm, Bapatla kharif during 2019. Eight treatments of various inorganic and organic proportions were applied and replicated thrice in a randomized block design. The results revealed that the maximum growth, yield and quality of pearl millet was obtained with application of 75% STBN (Soil Test Based Nitrogen) + 25% vermicompost + Azospirillum @ 5 kg ha-1. Strategic planning in terms of a combined application of organic manures with inorganic fertilizers will not only improve soil health, but also benefits farmers by lowering their reliance and expenditure, exclusively on
