Nutrient Uptake and Profitability of Kharif Green Gram (Yigna radiata L. Wilczek) as Influenced by Phosphorus Levels and PSB under Custard Apple (Annona squamosa) Based Agri-Horti-System

摘要

A field experiment was conducted during kharif season of 2009 to study the effect of phosphorus levels and PSB on growth and yield of kharif green gram (Vigna radiata L. Wilczek) under custard apple (Annona squamosa) based agri-horti-system N, P and Kconcentration in seed and straw and their uptake of green gram showed the maximum values under 40 kg P_2O_5/ha + PSB (T_7) but significantly superior to rest of the treatments. Results further showed that with regard to grain yield (998.20 kg/ha), strawyield (2893.0 kg/ha), cost of cultivation, gross returns, net returns (16507.0 Rs/ha ) and B : C ratio (2.43 Rs), application of 40 kg P_2O_5/ha + PSB (T_7) which in most of the cases was at par with 30 kg P_2O_5/ha +PSB (T(i) excelled the remaining treatments.
