Effect of different levels of drip irrigation, plant density and spacing on the yield of maize hybrid (KSC700)

摘要

This study was investigated to establish the effects of drip irrigation, density and spacing on yield and yield components of maize hybrid KSC700. A strip block design with 24 treatment combination in a randomized complete block was carried out at the experimental station of Islamabad. The results indicated that the effect of different amounts of water for the traits PH, EL, TGW, grain number per row, the percentage of cob and yield were significant (P<0.01). Effect of planting density for most of the traits found to be significant (P<0.01). Effect of planting pattern of traits and yield factor was not significant. The highest grain yield was belong to treatments of 75,000 plant per ha x water requirement of 125% and 100%, with 14,613 and 14,631 kg ha(-1), respectively. High yield productivity was observed for the treatment of the water requirement of 125% xplant density of 70 thousand plant per ha with production of 13,698 kg, and this treatment seems to be suitable for recommendation to farmers in Kermanshah.
