Abstract
The experiment was conducted to find out the most fesible intercrop in cotton and monetary
benefit of different intercrops, based on one year investigation it was found that growth parameter like
plant height of cotton was significantly higher in intercropping upto 75 DAS after that the plant height
was not influenced by intercropping treatments. Cotton intercropped with greengram accumulated
significantly higher dry matter per plant as compared to cotton intercropped with pearlmillet. Quality
parameter of cotton were not influenced by different treatments. Number of boll per plant was
significantly higher in cotton when intercropped with greengram. Boll weight was at par in sole and
intercropped Bt. cotton. Seed cotton yield was significantly higher in greengram intercropped
treatments (4663 kg ha-1, 4550 kg ha) in Bt. cotton intercropped with greengram (1:1) and (1:2)
respectively. Greengram and pearlmillet with (1:2) were dominated by cotton and same was indicated
by their negative aggressivity values. Intercropping of Bt. cotton + greengram (1:2) provided highest
cotton equivalent yield (5028 kg ha-1), net return (Rs. 187267 /ha) and B: C (3.52) with LER (1.70),
followed by Bt. cotton + greengram (1:1). Therefore, for maximizing the monetary returns, farmer
should opt for greengram as a intercrop in cotton (1:1) or (1:2) row ratio.
