Abstract


A field experiment was conducted at CCSHAU, Hisar during 2011-12 and 2012-13 to evaluate the intercropping of sorghum (Sorghum bicolor) in dhaincha (Sesbania aculeata) grown for seed during kharif season and their impact on succeeding wheat grown with three levels of nitrogen [50, 75 and 100 % recommended dose of nitrogen (RDN)] in split plot design with three replications. The results revealed that 1:1 row ratio of dhaincha and sorghum at 30 cm spacing succeeded by wheat was found most economical and feasible cropping system among all the treatments with highest wheat equivalent yield (7.22 tonnes/ha), system profitability (Rupees 241/ha/day), production efficiency (2.44 tonnes WEY/ha/day), net return (71.4 × 103 Rupees/ha ), B:C ratio (1.32), energy productivity (285.4 kg/ MJ) and apparent nutrient use productivity of 20.3 kg WEY/ha-kg. The 1:1 row ratio of dhaincha with sorghum yielded almost equal seed yield of dhaincha (only 2.8% reduction) with additional yield of 17.8 tonnes/ha sorghum fodder over sole crop. Hence, for seed production dhaincha be sown at 60 cm spacing intercropped with one row of fodder sorghum in between two rows of dhaincha followed by wheat to supplement the income of farmers.
