Effect of Foliar Applied Urea on Growth and Yield of Wheat (Triticum Aestivium L.)

摘要

The aim of this study is to assess effect of foliar application of urea on growth and yield of wheat crop. The field experiment was conducted to observe the effect of foliar applied urea on growth and yield of wheat. The experiment was laid out in a three replicated randomized complete block design (RCBD) having net plot size 5×4m= (20 m2). The wheat verity TJ-83 (Tando Jam-83) was tested against six treatments of foliar applied urea such as (T1= control (sole water), T2=1%, T3= 2%, T4=3%, T5=4%, and T6=5%). Basal dose of phosphorus @ 84 kg hasup-1/sup and nitrogen @ 120 kg hasup-1/sup was applied at the time of sowing. The results indicated that the maximum plant height (97.1 cm), number of tillers plant-1 (10.0), spike length (12.4 cm), spikeletes spikesup-1/sup (22.5) number of grains spikesup-1/sup (65.4), grain weight spikesup-1/sup (26.4) seed index (73.2 g), straw yield (6275.3 kg hasup-1/sup) andgrain yield (5774.6 kg hasup-1/sup) was observed in foliar applied urea @ 5%. The results were statistically significant. However, foliar applied urea @ 4% was ranked 2nd and it was recorded the plant height (96.2 cm), number of tillers plant-1 (20.4), spike length (12.0 cm), spikeletes spikesup-1/sup (21.8) number of grains spikesup-1/sup (63.9), grain weight spikesup-1/sup (25.3) seed index (71.7 g), straw yield (6035.3 kg hasup-1/sup) and grain yield (5534. 6 kg hasup-1/sup). However the foliar applied urea @ 3%, 2% and 1% were also significantly affected on all the growth and yield traits of wheat, whereas, the lowest values were also recorded in control treatment in all the yield traits of wheat.
