It was found that a short-season mungbean (Vigna radiata) crop could be taken before the commonly-grown castor crop but that castor yields were reduced by the delayed sowing. If the castor was sown after the harvest of mungbean in a sequential system the profits were less than from a sole castor system. Relay-sowing the castor 20 days before the harvest of mungbean gave 9 $US ha−1 greater profit than sole castor, but this is probably not enough to justify the more intensive double crop system. On the other hand a reasonable yield of horsegram (Macrotyloma uniflorum) could be produced after an early pearl millet crop, giving a worthwhile extra profit of 21 $US ha−1 compared with sole pearl millet. Ratooning the sorghum gave ratoon yields that averaged only 14% of the first crop, so this system was not considered suitable for these lighter Alfisols.

Intercropping systems of pearl millet/groundnut, sorghum/pigeonpea and groundnut/pigeonpea gave average yield increases of 24, 47 and 46%, respectively, compared with both component crops grown separately. Compared with growing only the higher value sole crop, increases in profits were 16, 82 and 120 $US ha−1 for the same three systems, respectively. It is concluded that intercropping systems provide the best opportunity for increasing cropping intensity on medium-deep Alfisols.","1985",,,"Experimental Agriculture","21",,"Cambridge University Press",,"271-280",,,,,,,,,,,"TRUE",,,,,,,,"","http://dx.doi.org/10.1017/S001447970001262X","http://scholar.google.co.in/scholar?hl=en&q=allintitle%3A+Evaluations+of+Alternate+Cropping+Systems+for+Alfisols+of+the+Indian+Semi-arid+Tropics&btnG=Search&as_sdt=0%2C5&as_ylo=&as_vis=0","author",,"","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
