Abstract

An experiment was conducted during 2014 on spring maize hybrids and potash levels at Agronomy Research Farm of The University of Agriculture Peshawar, Khyber Pakhtunkhwa Pakistan. A set of four hybrids and four potash levels were evaluated in randomized complete block (RCBD) design having four replications. Experimental results revealed significant differences for days to tasseling, days to silking, mean single leaf area, plant height, and number of plants at harvest, thousand grains weight, grain yield and biological yield. Mean data ranged from days to tasseling (62 to 67), days to silking (69 to 74), mean single leaf area (440.15cm2 to 494.28cm2), plant height (204cm to 215cm), number of plant at harvest not effected by potash level, grain ear (520g to 547g), 1000 grain weight (375g to 414g), grain yield (3424 kg ha-1) to (4192 kg ha-1), biological yield (11118 kg ha-1 to 13580 kg ha-1). Based on the result of this study significantly delay in tasseling was observed with 120 kg K ha 1. Among the hybrids tasseling was delayed (67 days) in 30K08.
