The effects of green manuring with dhaincha ( Sesbania aculeata ) and sunhemp ( Crotalaria juncea ) in combination with four levels of urea-N (0, 75, 150 and 225 kg N/ha) on the productivity of a subsequent sugarcane ( Saccharum officinarum ) crop and the fertility of the soil were examined. C. juncea contributed more nitrogen to the soils when ploughed down than S. aculeata (56·7 v . 40·0 kg N/ha). The green manures and the supplemented urea-N increased cane yield by 2 to 26% and 26 to 57%, respectively. The organic matter, total N, available P and S of the soil was only slightly increased by the incorporation of green manures.
