Effect of Different Levels of Boron for Improving the Yield and Concentration of Boron in Wheat Crop (Triticum aestivum L.)

Abstract

A field experiment was conducted to study the “Effect of Different Levels of Boron for Improving the Yield and concentration of Boron in wheat Crop (Triticum aestivum L.) during the Winter (Rabi) Season of 2012-2013 at the Research Farm of the Department of Agricultural Chemistry and Soil Science, Udai Pratap Autonomous College, Varanasi, Uttar Pradesh, India. Six treatments, viz. T0: Control (no input), T1: B @ 0.5 kg ha-1, T2: B @ 1.0 kg ha-1, T3: B @ 1.5 kg ha-1, T4: B @ 2.0 kg ha-1, T5: B @ 2.5 kg ha-1, and N, P2O5, and K2O were applied at the recommended dose @ 120: 80: 60 kg ha-1, respectively, were comprised in a randomized block design (RBD) with the three replications. The results revealed that different levels of boron significantly improved the yield and yield-attributing characters of wheat. Maximum grain yield (37.70 q ha-1), straw yield (47.13 q ha-1), total dry matter (84.48 q ha-1) and dry weight of root g-3 plant at 60 DAS (0.318) were recorded with Boron @ 2 kg ha-1. Moreover, maximum dry weight of shoot-3 plant at 60 DAS (1.91) was observed with boron at 2.5 kg ha-1). Maximum B concentration in 3rd leaf (40.63 mg kg-1) B concentration in grain (25.37 mg kg-1) B concentration in straw (30.87 mg kg-1) B concentration in root (160.20 mg kg-1) was recorded under Boron @ 2.0 kg ha-1.
