Studies on the effect of sulphur with and without FYM on yield and quality of mustard crop in Vertisols

An experiment was conducted at the field of Department of Soil Science and Agril. Chemistry, JNKVV, Jabalpur (M.P) during Rabi season of 2013-14 and 2014-15 under AICRP on MSN in a Factorial randomized block design with three replications and ten treatments comprising viz., T1 (Control), T2 (15 Kg S ha-1), T3 (30 Kg S ha-1), T4 (45 Kg S ha-1), T5 (60 Kg S ha-1), T6 (FYM 5 t ha-1), T7 (15 Kg S ha-1+ FYM 5 t ha- 1), T8 (30 Kg S ha-1 + FYM 5 tha-1), T9 (45 Kg S ha-1 + FYM 5 t ha-1) and T10 (60 Kg S ha-1 + FYM 5t ha-1).The results obtained from the present investigation clearly indicated that yield of seed and straw increased significantly with enhancing sulphur up to highest level of 60 kg ha-1 + FYM 5 t ha-1.S X FYM interaction showed significant difference in seed protein content. Treatment combination of Sulphur 60 kg ha-1+ FYM 5 t ha-1 recorded maximum percentage of protein (18.85%) and oil (41.29%) content in seed. However, better improvements in yields were exhibited when S and FYM were integrated together. This increase might be due to steady decomposition of FYM and release of nutrients throughout the crop growth period coupled with better assimilation of nutrients. Highest seed (1684.70 kg ha-1) and Stover (4739.82 kg ha-1) yields was recorded with the application of Sulphur 60 kg ha-1 + FYM 5 t ha-1 over rest of the treatments.
