Effect of residual fertility on oil quality of Indian mustard (Brassica juncea L. Czern & Coss)

Abstract

An experiment was conducted at Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, U.S. Nagar (Uttarakhand) India, during 2018-19 to study the effect of residual fertility of sweet basil crop on oil quality of succeeding mustard crop. From the study it was found that the oil quality of mustard variety PR 20 in terms of protein, oil content and fatty acid composition did not influence much with the recommended dose of fertilizer and residual fertility treatments. However, in sweet basil- mustard cropping system, the application of 120 kg N, 60 kg P2O5, 40 kg K2O and 40 kg S ha-1 in sweet basil crop and growing mustard on residual nutrients improved the oleic acid content in mustard oil, which is consider good for human health.
