EVALUATING SEED RATE, CUTTING AND NITROGEN LEVEL STUDY OF YIELD AND YIELD COMPONENTS OF TRITICALE

Abstract

This field experiment was conducted at New Development Farm, The University of Agriculture Peshawar to evaluate the seed rate, cutting and nitrogen level study of yield and yield components of triticale. Randomized complete block (RCB) design with split plot arrangement having four replications of each treatment was used. A control treatment was also included for comparison. The size of the sub plot was 1.5 m × 3 m. The row-row distance was 30 cm with five rows. Phosphorous was also applied at the rate of 90 kg ha-1 at the time of sowing. Irrigation was done as per required by the crop. All of the phosphorus and sulphur were applied at sowing time. Finding of the experiment illustrated that maximum emergence m-2 (118), fresh fodder yield (136 g m-2 ), days to heading (117 days), plant height (98.6 cm) and delayed maturity (151 days) with seed rate of 140 kg ha-1 , while higher number of productive tillers (233 m-2 ), grains spike-1 (44) was recorded at seed rate of 100 kg ha-1 . Higher unproductive tillers (17 m-2 ) was obtained at the seed rate 120 and 140 kg ha-1 . Application of N at the highest level in (150 kg ha-1 ) delayed day to heading (117 days), days maturity (150 days), produced taller plants (210 m-2 ), higher fresh and dry weight (129 and 75 g m-2 ), more number of grains spike-1 (42) as compared with other levels of N. Higher productive tillers (222 m-2 ), CGR (14 g m-2 day-1 ) were recorded at 120 kg N ha-1 . It can be concluded from the study that increase in seed rate at140 kg ha-1 and increase in nitrogen levels enhances the emergence m-2 , fodder yield, days to heading, plant height, and delayed maturity
