An experiment conducted during 1995 and 1996 on sandy soils in rainfed condition revealed that Cenchrus ciliaris L. gave highest dry-matter yield (50.67q/ha) at 40 kg N/ha with 50 cm x 50 cm spacing in sole cropping, which was at par with grass planted at 100 cm x 50 cm spacing at same level of N. The response of Lasiurus sindicus to different rates of N application was not significant ( 1995) due to low and ill-distribution of rainfall. The highest dry forage yield (32.30 q/ha) of L. sindicus was recorded at 50 cm x 50 cm with 40 kg N/ha in 1996. The intercropping of L. sindicus with C. ciliaris resulted in a highest yield of 45.33 and 47.00 q/ha at 40 kg N/ha with 50 cm x 50 cm spacing and was significantly higher over than that obtained at 100 cm x 50 cm spacing during 1995 and 1996 at same level of N. The lowest dry-forage yield was recorded where no nitrogen was applied at all the spacings
