Effect of sulphur and zinc on yield and uptake of nutrients by mustard (Brassica spp. L.) under rainfed condition

Abstract

Fields experiments were conducted for two years (2013-14 and 2014-15) with mustard (Brassica spp. L.) as a test crop under rainfed conditions on sandy loam soils with 5 levels of sulphur (0, 15, 30, 45 and 60 kg ha-1) and 4 levels of zinc (0, 2.5, 5.0 and 7.5 kg ha-1) in Factorial randomized block design with three replications. Seed and stover yield increased significantly up to 45 kg S ha-1 and 5.0 kg Zn ha-1 application. Application of 30 kg S ha-1 increased the seed yield by 51.4 and 28.4% in 2013-14 and 55.3 and 27.5% in 2014-15 over control and 15 kg S ha-1, respectively. Nitrogen, phosphorus, potassium, sulphur and zinc uptake by seed and stover significantly up to 45 kg S ha-1 and 5.0 kg Zn ha-1 application.
