Effect of Increasing Levels of Phosphorus and Seed Rate on the Economic Yield of Maize

M. Qasim, Himayatullah and M. Subhan

Number of cobs per plot, 1000-grain weight and grain yield were significantly effected by various levels of phosphorus and seed rate. Maximum number of cobs per plot (72.58), 1000-grain weight (334.08 g) and grain yield (3154.43 g) were obtained from plots receiving P2O5 @ 200 kg ha ^-1. Similarly, seed rate @ 60 kg ha ^-1 gave comparatively higher economic yield. Hence P2O5 @ 200 kg ha ^-1 and seed rate @ 60 kg ha ^-1 proved to be the best fertilizer and seed rate among all the treatments.
