Effect Of Vermi-Compost And Sesbania Acculata Green Manuring On Fallow Land Toria Oilseed Production

Summary

A field experiment was carried out during summer and winter season of 2004-05 and 2014-15 to study the effect of nutrient management by using value added vermi bio-manures and green manuring effect on Toria crop in sandy loam soil at abandoned Farm land of Indian Veterinary Research Institute, Bareilly, U.P., India. Result indicated that application of vermi bio-manure @ 10t/ha produced more yield than green manuring. In both years vermi compost manuring produced more yield in comparison to green manuring during 2004-05 and 2014-15. The reason might be that vermi-compost supplied early nutrients than the green manuring. Among the Toria varieties PT-330 produced maximum yield (13.2 and 11.4 q/ha) in both the trials.  Oil content was also found higher (33.7% and 36.3%) in the P-330 variety and followed by PT-570. Second maximum green yield 12.5 q/ha and 10.7q/ha and wherein oil content was observed 36.4% and 34.5%, respectively. Soil fertility status was improved during long term effects (10 years) process in both green manuring and vermi-compost application trials. Major and minor nutrients were increased due to availability of more organic carbon, increase soil moisture contents and higher soil microbial activities during the period of 10 years.
