Effect of integrated nitrogen management on yield, economics and soil properties in sorghum-green gram cropping sequence under South Gujarat


Author(s): JB Patil, MK Arvadia and DS Thorave

Abstract: A field experiment was conducted at the College Farm, Navsari Agricultural University, Navsari (Gujarat) on clayey soil to study the residual effect of INM and direct effect of RDF on growth, yield and economics of green gram in sorghum-green gram copping system during the year 2015-16 and 2016-17. The seven treatments consisted of integrated nitrogen management to sorghum in rabi season as main plot treatments in RBD. During summer season each main plot treatments was splited into three sub plot treatments with three levels of recommended dose of fertilizers to green gram in split plot design. Result revealed that 100% RDF through inorganic fertilizer + biocompost @ 10 t/ha was found significantly superior grain (34.55 q/ha) and stover yield (87.17 q/ha) compared to rest of treatments in sorghum. Residual effect of preceding crop sorghum fertilized with T1-100% RDF through inorganic fertilizer + biocompost @ 10 t/ha recorded higher grain yield (9.84 q/ha) and stover yield (23.64 q/ha) of succeeding green gram. Similarly, statistically same values of grain yield, stover yield of green gram were recorded with the application of 100% RDF and 75% RDF but are significantly superior to control. Maximum net return in sorghum (Rs. 59146/ha), residual effect on summer green gram (Rs 35548/ha) and crop sequence (Rs 94694/ha) with higher B:C ratio (2.42) were recorded in the treatment receiving 100% RDF through inorganic fertilizer + biocompost @ 10 t/ha. However, in case of direct application of RDF levels, highest net returns was recorded with the application of 100% RDF and followed by 75% RDF. Significantly higher sorghum equivalent yield (64.08 q/ha) was recorded with application of 100% RDF through inorganic fertilizer + biocompost @ 10 t/ha to rabi sorghum and under 100% RDF and 75% RDF to green gram. As regards to the economics of treatments combination of cropping sequence, T1S1 and T1S2 recorded maximum net monitory return of
