| dc.description.abstract | A field experiment was conducted on medium deep black soil under rainfed condition at the Agricultural Research Station, Dharwad Farm, during the kharif season of 1998-99 to study the effect of row proportions of cotton and pigeonpea (2:1, 3:1, 4:2 and 6:2) and pigeonpea population (50 and 75 per cent of sole crop) on intercropping systems. Sole crops of cotton and pigeonpea were also raised. Sole crop of cotton and pigeonpea realised significantly higher 5deld than intercropping system. The seed cotton 3deld produced under 6:2 row proportion (1059 kg/ha) was significantly more than 2:1 (664 kg/ha), 3:1 (728 kg/ha) and 4:2 (823 kg/ha) row proportions. On the contrary, the seed yield of pigeonpea under 2:1 (1464 kg/ha), 4:2 (1463 kg/ha) and 3:1 (1421 kg/ha) row proportions were significantly higher than 6:2 row proportion (992 kg/ha). However, pigeonpea population levels and interaction effects had no significant effect on the cotton and pigeonpea ykld. Based on Area Time Equivalent (ATER) Ratio, cotton and pigeonpea intercropping found to be 18 per cent more efficient in utilising land area and time than of the sole crops. Mean of intercropping systems, intercropping of cotton with pigeonpea has recorded the lower net returns (Rs.l7,236/ha) and B:C ratio (L04) as compared to sole cotton (Rs.20,380/ha and 1.40, respectively). The net return and B:C ratio derived from 4:2 and 6:2 were higher over 2:1 and 3:1 row proportions. Among the cropping systems, highest gross and net returns were obtained with intercropping of cotton and pigeonpea with 6:2 row proportions at 100:50 per cent plant population followed by intercropping system with 4:2 row proportions at 100:75 per cent plant population and sole cotton. These systems gave more gross, net returns and B:C ratio than sole pigeonpea. 4 From the results of this investigation it is concluded that sole cotton as well as intercropping of cotton and pigeonpea with 6:2 proportions at 100:50 per cent plant population were better cropping systems than sole pigeonpea under rainfed condition. | en_US |
