“…Many tropical grain legumes have the capacity to increase soil productivity thereby benefiting the subsequent crop though wide variations may occur in their capacity to do so. Whereas Jones (1974) found greater benefit from groundnuts than from cow pea on a subsequent crop of maize, Giri & De (1979) reported that the yield of pearl millet was in-creased by 24-2% after cow pea, 22-6% after groundnuts and 12-1 % after pigeon pea. Quantitatively these benefits from cow pea and groundnuts were equivalent to 60 kg N/ha applied to pearl millet after a cereal, while that from pigeon pea was of the order of 30 kg N/ha.…”

Experiments made for 2 years on a sandy-loam soil showed that previous grain crops of mung bean (Vigna radiata), cow pea (V. unguiculata) and black gram (V. mungo) increased the grain and straw yield of a subsequent crop of rice relative to previous fodder crops of maize or guar bean (Cyamopsis tetragonoloba) or a grain crop of Phaseolus bean (Phaseohcs vulgar is). The benefits from preceding crops of mung bean, cow pea or black gram were equivalent to 36-67 kg N/ha of chemical fertilizer applied to the rice crop following a cereal. The legumes improved yield-contributing characters such as number of productive tillers/m 2 , panicle length and number of grains/panicle. The yield increase from the preceding legumes was noted even when the rice crop was given increasing rates of fertilizer up to 90 kg N/ha. bicarbonate soluble P/kg soil), medium in K (95mg/kg soil) and organic carbon (0-78%).

A 2-year field study indicated that pearl millet yielded more when sown after fallow, cow pea and green gram than after maize. Preceding fallow, cow pea and green gram reduced the nitrogen requirement of pearl millet by 40 kg/ha compared with maize. Pearl millet responded linearly up to the highest rate of nitrogen (80 kg/ha). N applied to millet had no residual effect on the subsequent crop of chickpea. The chickpea yield followed the order fallow > green gram ^ cow pea > maize. Chickpea responded to phosphorus up to 40 kg/ha. Green gram-pearl millet-chickpea proved the most profitable cropping sequence. Continuous cropping and application of nitrogen and phosphorus improved the organic carbon and available phosphorus but decreased the available potassium status of the soil.

“…Sole cropping of groundnuts has shown considerable residual effects on subsequent cereal crops (Jones, 1974;Giri and De, 1979;Nambiar and Dart, 1980). A reduction in the N 2 -fixation of intercropped groundnuts suggests that the residual effect in these situations may be less than that expected from the general growth and yield of the legume crop.…”
