ABSTRACT
A field experiment was conducted at Agronomy Farm, S.K.N. College of Agriculture, Jobner (Rajasthan) . The experiment consisting 36 treatment combinations of 3 levels of compaction (0, 2 and 4 passing of 500 kg iron roller) and 3 levels of irrigation (one irrigation at flowering, two irrigations at flowering and pod filling and three irrigations at branching, flowering and pod filling stage) and 4 levels of sulphur (0, 30, 60 and 90 kg S ha-1) through gypsum. The results indicated that SO42--Sulphur retention in soil at flowering and harvesting stage of mustard crop, were increased significantly with increasing levels of compaction and sulphur over control. whereas, application of 4 passing of 500 kg iron roller, 60 kg S ha-1 and two irrigations at different growth stages recorded significantly higher values of seed and stover yield of mustard crop over control and lower levels.
Key words :
Irrigation, Seed and stover yield of mustard, SO42--S retention in soil, Soil compaction, Sulphur.
