Effect of Varying Levels of Boron and Sulphur on Yields and Nutrient Uptake of Linseed (Linum usitatissimum L.) Grown in a Mollisol

Abstract

A greenhouse experiment was conducted to study the effect of effect of varying levels of boron and sulphur on yield and nutrient uptake of linseed (Linum usitatissimum L.) grown in a Mollisol. The experiment was conducted under factorial completely randomized design with three replications and consisted of six levels of each of boron (0, 0.5, 1.0, 1.5, 2.0 mg kg−1soil and two foliar sprays of 0.2% boron) and sulphur (0, 10, 20, 30, 40 and 60 mg kg−1soil). The different doses of sulphur and boron and their interaction had significant effect on seed and stover yields, B and S concentrations and uptake by linseed crop indicating a differential requirement of boron and sulphur by the crop. The highest seed yield was recorded under the combined application of 2 mg B kg−1 soil and 60 mg S kg−1 soil.
