Abstract

A pot experiment was carried out in green house to study the effect of nitrogen and potassium on nutrient content, uptake and grain yield of wheat. The increase in nitrogen level increased the straw and wheat yield of wheat. The protein content also increased with the increase in level of nitrogen level. The nutrient content and uptake also increased with the increased in level of nitrogen level. The increase in potassium level increased the straw and wheat yield of wheat. The protein content also increased with the increase in level of potassium level. The nutrient content and uptake also increased with the increased in level of nitrogen level.

Abstract

Field studies were conducted in 2008-09 and 2009-10 at Pulse Research Area of Chaudhary Charan Singh Haryana Agricultural University, Hisar to determine the effect of post emergence herbicides on nutrient uptake by field pea and weeds. All the herbicide treatments significantly reduced the nutrient uptake by weeds than weedy check. Among the herbicide treatments, minimum and maximum uptake of nutrients by weeds and crop, respectively was recorded under the application of pendimethalin 1.5 kg ha^-1 followed by imazethapyr 50 g ha^-1.

Abstract

An On Farm Trial was initiated in the Narayanpur village of Garhwa. The On Farm Trial was planned in the Rabi of 2008. Source of technology selected was Japanese weeder and cono weeder. Grain yield harvested was significant in all the treatments. The maximum grain yield of 41 q/ha were recorded in treatment 2 wherein weeding was done with Japanese weeder followed by three treatment these which weeding was done with cono weeder (34q/ha). The least grain yield of 20.5q/ha was recorded under farmer's practice in which hand weeding was done. In terms of energy efficiencies, cost to benefit ratio noticed, and higher grain yield output, weeding with Japanese weeder was considered to be successful on farm trial followed by weeding with cono weeder.
