Effect of Weed Management Practices, Row Spacings and Fertilizer Levels on Growth and Yield of Wheat Nanda S. S., Patro G. K. Department of Agronomy, Orrisa University of Agriculture and Technology, Bhubaneswar, India. Abstract Grasses (59%), sedges (7%) and non-grassy weeds (34%) infested the wheat crop. Recommended dose of NPK (100-50-50 kg/ha) due to its more efficient use by the crop resulted in better smothering of weed population. Lower levels of NPK (50%) significantly reduced the dry matter of weeds. Pre-emergence application of metoxuron at 1.5kg/ha was effective in controlling the weeds and caused substantial improvement in plant growth and grain yield of wheat (3225 kg/ha). The combined influence of 100% NPK, narrower spacing (15 em) and metoxuron use could produce highest grain yield of 3757 kg/ha and highest benefit cost ratio. Top | |
