Effect of cropping system and nutrient management practices on productivity and profitability of Indian mustard (Brassica juncea L.)

Abstract

A field experiment was conducted during 2016-17 and 2017-18 at the Research Farm, M G C G V, Chitrakoot Satna (M.P.) to study the effect of cropping system and nutrient management practices on production and profitability of mustard. Out of the three cropping systems, greengram-mustard resulted in significantly highest siliquae/plant (137.84; 143.96) and grains/siliqua (12.73; 12.84). The green gram-mustard recorded significantly higher seed yield (1178 and 1283 kg/ha) and stover yield (3918 and 4266 kg/ha) of mustard as compared to sesame-mustard and maize-mustard cropping system. Application of 100% N equivalent through FYM in kharif +100% N equivalent through FYM in rabi produced highest siliquae/plant (148.23 and 153.43) and seeds/siliqua (12.80 and 12.88) during two respective years. However, the treatment having 200% N through FYM (100% N equivalent through FYM in kharif and 100% N equivalent through FYM in mustard) resulted in the maximum seed yield (1092 and 1191 kg/ha) and stover yield (3781 and 4128 kg/ha) of mustard followed by 150% NPK + 5 t FYM /ha (75% NPK+5 t FYM/ha in kharif +75% NPK in rabi) and (50% NPK+5 t FYM/ha in kharif +100% NPK in rabi). The mustard after green gram provided maximum net income of `46,461/ha with 2.50 B:C ratio. Net returns and B:C ratio of mustard obtained maximum (`40539/ ha; 2.32) under 75% NPK+5 t FYM/ha in kharif and 75% NPK in rabi season.
