Nadar Khan, Muhammad Qasim, Fayaz Ahmed, Falak Naz and Razaullah Khan    

Abstract: A field experiment was carried out at Himalayan Agricultural Research Station (PARC),Kaghan during kharif season 2001 to study the effect of various sowing dates on maize. The crop was sown on 2nd, 9th, 16th, 23rd, 30th May, 6th and 13th June. Days to 50% silking, days to maturity, number of grains row-1,100 grain weight (gm) and grain yield (kg ha-1) was significantly affected by various sowing dates while the effect on number of rows ear-1 was non significant. Delay in sowing substantially reduced days to 50% silking, days to maturity, number of grains row-1, 100 grain weight (gm) and grain yield (kg ha-1).Maximum grain yield (2988.89 kg ha-1) was record in crops sown on 2nd May while minimum grain yield (780.44 kg ha-1) was observed in crops sown on 13th June. Early sowing produced highest yield as compared to delay sowing.
