The field experiment was conducted to find out the effect of seed biopriming with biocontrol agents using Trichoderma viride 60% for 9h and Pseudomonas fluorescens 60% for 12 h along with nonprimed seed, which constituted the main plot treatments in Field No. 37E of TNAU, Coimbatore exclusively maintained for organic cultivation situated in North Western agro-climatic zone of Tamil Nadu during Kharif 2013 and Rabi 2013. Biopesticide sprays of Panchakavya 3%, dashparni extract 10%, neemastra 10%, agneyastra 3%, brahmastra 5%, cow’s urine 5%, neem seed kernel extract 5% and neem oil 1% along with imidacloprid 0.3 ml/l formed the subplot treatments. For organic seed production, the results revealed that, seed biopriming with P. fluorescens 60% for 12 h and neem seed kernel extract 5% sprays were highly effective in both the seasons.
