Effect of Different Sources of Sulphur on the Yield of Indian Mustard (Brassica juncea L) in Pearl Millet-Mustard Cropping System

摘要

The mean seed yield of mustard var. T-59 (Varuna) was recorded maximum (18.80 q ha ha~(-1)) during 1992-93 and 1993-94 under application of gypsum for 40 kg S ha ha~(-1) followed by ammonium sulphate (16.99 q ha ha~(-1)), besides 80 kg N and 60 kg P_2O_5 ha~(-1) - as a recommended dose at Bichpuri Centre, Agra (U. P.). However, the other sources of sulphur viz., elemental sulphur, pyrite and single superphosphate remained inferior. The lowest yield (14.68 q ha ha~(-1)) could be recorded under elemental sulphur.
