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 greengram in sorghum-greengram copping system during the year 2015-16 and 2016-17. The seven treatment 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 viz., S1 - 100% RDF, S2 - 75% RDF and S3 – Control to greengram in split plot design. Residual effect of 100 % RDF through inorganic fertilizer + biocompost @ 10 t/ha applied to rabi sorghum showed higher growth in terms of plant height (54.03 cm), number of branches (4.78), dry matter accumulation (17.44 g), yield attributes viz., number of pods/plant (21.03), pod length (7.68 cm) and seed weight/plant (4.00 g), grain yield (9.84 q/ha) and stover yield (23.64 q/ha) of green gram in pooled analysis. Treatments 100% RDF and 75% RDF are found statistically at par but recorded significantly higher values of growth attributes, yield attributes, seed and stover yields during individual years and in pooled analysis. Residual effect of INM treatment 100 % RDF through inorganic fertilizer + biocompost @ 10 t/ha recorded maximum net monetary returns of ` 35548/ha with B:C ratio 2.16 of summer greengram. However, in case of direct application of RDF levels, highest net returns of ` 30490/ha with B:C ratio of 1.97 were recorded with the application of 100% RDF and followed by 75% RDF with net returns of ` 29947/ha with B:C ratio of 1.97.
