Influence of Different Level of Boron on Uptake of Nutrients in Wheat (Triticum aestivum L.) Crop

A field experiment was conducted at the research plot of Udai Pratap Autonomous College (UPAC), Varanasi, Uttar Pradesh, adjoining the Department of Agricultural Chemistry and Soil Science, to study the effect of levels of boron on nutrient uptake in the wheat crop of the rabi season 2012-13. Boron was applied at six levels (0.0, 0.5, 1.0, 1.5, 2.0, and 2.5 kg ha-1), with NPK @ 120:80:60, and the experiment was laid out in Randomized block design (RBD) with three replications. The application of 2 kg boron ha-1 recorded significantly higher boron uptake (95.50 g ha-1) in grain, higher uptake of boron in straw (145.27 g ha-1), total boron uptake (240.77 g ha-1). The amount of increase in P uptake above control was larger at the optimum B level (2.0 kg B ha-1) treatment. The authors suggested the use of optimum level of boron for better nutrient uptake.
