Influence of levels of Nitrogen and Zinc on yield attributes and economics of Knol-Khol (Brassica oleracea var. caulorapa) in Loamy Sand Soil of Jobner

Abstract

The experiment was conducted at Horticulture farm, S.K.N. College of Agriculture, Jobner (Rajasthan) during rabi, 2012-13 to study influence of levels of Nitrogen and Zinc on yield attributes and economics of Knol-Khol (Brassica oleracea var. caulorapa) of Early White Vienna variety, in the Loamy Sand Soil of Jobner. Results indicated that application of Nitrogen up to 100% RDN and Zinc up to 4kg ha-1 ZnSO4 significantly improved yield attributes and also maximum net returns of Rs. 223597 and 221617 were recorded. While highest benefit cost ratio of 4.81:1 and 4.82:1, were recorded under the treatment of nitrogen @ 125 percent of RDN and zinc @ 6kg ha-1 respectively.
