Evaluation of Different Herbicides with NPK on Growth and Yield of Wheat (Triticum aestivum L.) in Field Trial of Aligarh Soil

This field study was conducted on sandy loam soil of Aligarh district (U. P. ) India to examine the effect of different herbicides named pendimethalin, metsulfuron methyl, 2, 4-D, clodinafop and metribuzin with uniform dose of inorganic fertilizer (NPK) on growth and yield of wheat. The above mentioned herbicides were applied at three different concentrations, while NPK was applied @ 120: 60: 40 Kgha-1. This field experiment on Aligarh soil showed that high herbicide concentrations of all the herbicides tested were deleterious for wheat growth and yield as compared to other two (lower and medium) concentrations. In this field trial the use of pendimethalin @1000 gai. proved best for wheat, which may have exerted a positive effect on wheat yield as compared to other herbicides as noticed at harvesting. Metribuzin @ 250 gai. proved least effective herbicide from the point of view of wheat growth and yield. Metsulfuron methyl, 2, 4-D and clodinafop were not so effective as compared to pendimethalin for wheat. Use of NPK proved beneficial with herbicide for wheat growth and yield in this field study.
