Effect of graded levels of phosphorus and foliar fertilization on short duration redgram in rainfed Vertisol

Field experiments were conducted at Regional Research Station, Aruppukottai during the rabi seasons of 1998-99, 1999-2000 and 2000-2001 to study the effect of graded levels of phosphorus and foliar nutrition on short duration redgram in rainfed Vertisol. The pooled data revealed that application of 37.5 kg P2O2 ha-1 had recorded higher grain yield of 958 kg ha' with a net income of Rs.9338 ha-1 and B-C ratio of 2.32 than 12.5 kg P2O5 ha but on par with application of 25 kg P2O2 ha'. Foliar application of di-ammonium phosphate two per cent had improved the grain yield and income with high B-C ratio.
