Abstract

In a field trial at ICRISAT, Hyderabad pearl millet [P. americanum] cv. BK 560 was grown on a medium-deep alfisol under irrigated or rainfed conditions. Nutrient uptake, plant dry wt. and nutrient content at harvest were higher in the irrigated than in the rainfed crop. Nutrient uptake ceased in the rainfed crop at 40 days after sowing, but continued in the irrigated crop for 47-61 days. In both crops nutrients were redistributed from leaves to stem at grain filling. Nutrient uptake/day increased to a max. at 26-33 days, but daily nutrient uptake/m of root decreased with maturity. Relevant fertilizer placements were discussed.ADDITIONAL ABSTRACT:In a field trial at ICRISAT, Hyderabad pearl millet cv.
