Status of Available Sulphur and Micronutrients in Mustard Growing Areas of Northern Madhya Pradesh

摘要

Enhanced removal of micronutrients as a result of adoption of high yielding varieties, intensive cropping with high analysis NPK fertilizers, limited use of organic manures and less recycling of crop residues led to the depletion of secondary and micronutrient from the soil reserves. There are reports of decline in yield even use of recommended NPK fertilizers. The reduction in the yield is generally accounted to deficiency of secondary and micronutrients. Oilseed crops have been reported to depletethe soil sulphur (S) relatively to a greater extent because S uptake per tonne of grain production is high in oilseed. It is 3 to 4 kg for cereals, 8 kg for pulses and 12 kg for oilseeds (Tandon 1995).
