摘要:This experiment was conducted to determine the optimum levels of nitrogen (N) and phosphorus (P) fertilizer formaize production; and to see the interaction between different levels of N and P fertilizer on the growth andperformance of maize (Zea mays L.) BH-660 variety at Nedjo. The experiment had two factor: 5 levels of N (0,46, 92, 138, and 184 kg ha-1) and 5 levels of P (0, 23, 46, 69 and 92 kg ha-1) arranged in Randomized CompleteBlock Design (RCBD) with three replications. The sources of N and P were urea (46% N) and triple superphosphate (TSP) (46% P2O5), respectively. The main effects of N and P brought significant effect on thousandgrain weight. The interactions of N and P also significantly affected grain, and biomass yield; and harvest index.The highest grain yield (5497.5 kg ha-1) and biomass yield (16521 kg ha-1) were recorded at the highest rates ofN/P (184/92 kg ha-1).
