Abstract:
Nitrogen is primary nutrient that impact on green colour of plant that encourage vegetative growth of mustard. Sulphur is the secondary nutrient and is the essential constituent of amino acid. The factor A (nitrogen level) have four combinations i.e. No nitrogen, 40 kg, 80 kg and 120 kg and factor B (sulphur level) have also 4 combinations i.e. No sulphur, 15 kg, 30 kg and 45 kg. The highest oil yield was recorded in nitrogen treatment N3 (Nitrogen 120 kg) 679.338 kg/ha and in sulphur treatment S3 (Sulphur 45 kg) 574.166 kg/ha. The lowest oil yield was recorded in both control of nitrogen and sulphur treatments. It was found that nitrogen level of 120 kg/ ha and sulphur level of 45 kg/ha have significant result in terms of growth, yield and quality parameters because both of these nutrients directly regulate the photosynthesis. Its deficiency shows low chlorophyll contents in plants that facilitate poor growth and yield.
