Effect of organic manures on productivity, soil fertility and economics of greengram-sesamum crop rotation under dry farming conditions of North Gujarat 

Abstract

A field experiment was conducted at the All India Co ordinate Research Project for Dry land Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, District Banaskantha (North Gujarat) during kharif seasons from 2007 to 2015 to study the effect of organic manures on productivity, soil ferti lity and economics of greengram-seasamum crop rotation under dry farming conditions of North Gujarat. The soil of experimental plot was loamy sand in texture, low in organic carbon and available nitrogen, medium in available phosphorous and high in available potash. Four treatments viz., T, : Control ( No fertilizer), T2 : RDF through chemical fertilizer, T3 : RON through F. Y. M. and T4 : RON through vermicompost were tested in Randomized Block Design with six replications. The results revealed that application of 20 kg N/ha to green gram and 50 kg N /ha to seasamum either through vermicompost or FYM recorded the highest yield and net profit in green gram-seasamum crop rotation as well as improve the soil fertility.
