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 seeds of mustard variety Bio-902 @ 4 kg ha-1 were sown on 7th November and 30th October in the rows spaced at 30 cm apart. The results indicated that increasing level of compaction, irrigation and sulphur significantly increased the seed and stover yields, content and uptake of N, P and S in seed and stover, protein and oil content in seed. No significant difference in oil content was observed with increasing levels of compaction and irrigation during both years. However, sulphur application increased the oil content of seed.
Key words :
Irrigation, Quality of mustard, Soil compaction, Sulphur, Seed and stover yield of mustard.
