Studies on impact of organic manures on soil secondary and micro nutrients following two year vegetable cropping pattern (Okra-Dhaincha-Broccoli)

Abstract

A study was conducted at Organic Farming Research Centre of SKUAST -Jammu to find out the impact of organic manures on soil secondary and micro nutrients following two-year vegetable cropping pattern. Significant results were obtained in Iron with highest value 32.69 kg ha-1 observed in T8 in okra and 33.68 kg ha-1 in broccoli. No significant changes were observed in Exchangeable calcium and Magnesium, Total Nitrogen and in DTPA Copper, Zinc and Manganese in this two-year experiment, however it is possible that after a certain period of time change can be noticed in certain secondary and micro-nutrient availability.
