Abstract

A field experiment was carried out at Agricultural Research Farm of Institute of Agricultural Sciences, BHU, Varanasi to study the response of nitrogen sources and spacing on growth and yield of baby corn during the pre- Kharif season of 2008 and 2009.The results clearly revealed that 75% N through urea + 25% N through FYM (N2) and spacing of 40 cm × 15 cm (S₁) were found best source of nitrogen and spacing, respectively and their combination N2S1 (75% N through urea + 25% N through FYM + 40 cm × 15 cm spacing) emerged superior over all other treatment combinations in relation to growth, yield attribute and yield for commercial cultivation of baby corn under agro- climatic conditions of Varanasi.

Abstract

A field experiment was conducted during rainy season of 2013 at Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi to evaluate the effect of phosphorus levels and bio-organic sources on growth and yield of wetland rice cv. HUR-105. Factorial experiment was laid out in Randomized Complete Block Design involving four levels of phosphorus viz., control, 50 per cent RDP, 75 per cent RDP and 100 per cent RDP and three bio-organic sources i.e. PSB, PSB + BGA and PSB + BGA + FYM (5 t ha^-1) replicated thrice. Increase in the levels of phosphorus application upto 100 per cent RDP (60 kg P₂O₅ ha^-1) improved growth attributes, yield attributes, grain and straw yields. Combined use of PSB + BGA + FYM (5 t ha^-1) proved superior to PSB alone and PSB + BGA. Economic analysis indicated that integration of moderate phosphorus level (75% RDP i.e. 45 kg ha^-1) along with the use of PSB + BGA + FYM (5 t ha^-1) gave highest net return and B:C ratio.
