The effect of foliar spray of urea and di-ammonium phosphate (DAP) with and without basal dressing of fertilizer was studied on greengram Co4 at Tamil Nadu Agricultural University farm, Coimbatore during 1983-1984. Uptake of N and P was higher when basal application of 50 kg.ha was combined with foliar spraying of urea or DAP twice. The rate of nutrient uptake increased with age of the crop, and reached the peak at 40 and 60 days after sowing (DAS) for P and N respectively. No significant difference was observed in grain yield between urea and DAP foliar spray on equal N basis. The highest income and return rupee¹ invested were recorded by foliar application of urea twice.
