Abstract:
An experiment was conducted at Cereal Crops Research Institute Pirsabak Nowshera during 2002-03 on six wheat cultivars/advance lines to identify the best suitable time of planting in the central agro-ecological zone of NWFP. Randomized complete block design was used with 3 replications. Six planting dates were used from October 25th to December 15th with 10 days increment. Data were recorded on Days to 50% heading, Days to maturity, Plant height and Grain yield. Maximum number of days (132) to 50% heading were recorded when planting was done on October 25th Minimum number of days (114) were reported when planting was done on December, 15th. Maximum number of days (178) to maturity were recorded when planting was done on October 25th. Number of days to maturity decreased as planting was delayed with 10 days increment. Minimum number of days (130) were recorded when planting was delayed till 15th of December. Highest plant height (98 cm) was recorded when planting was done on October 25th and November 05th. Plant Height decreased as planting was delayed. Minimum Plant height (85 cm) was recorded when planting was delayed till 15th of December. Maximum grain yield (3937 kg ha-1) was recorded when planting was done on November 05th. Grain yield decreased as planting was delayed with 10 days increment. Minimum grain yield (2274 kg ha-1) was observed when planting was done on 15th of December. A negative correlation was recorded between planting dates and days to 50% heading, days to maturity, Plant height and Grain yield. The yield losses due to late planting recorded were 8% when planting was done on November 15th, 22% loss when planting was done on 25th November, 34% losses were incurred when planting was done on December 5th and 42% losses were recorded when planting was further delayed till December 15th. Hence it is concluded that first two weeks of November is the best time for obtaining higher yields from the recommended cultivars.
