Effect of different sources of nitrogen on various physiological parameters and their correlation with yield of cabbage (Brassica oleracea var. capitata L.)
Keywords:
physiological, Cabbage (Brassica oleracea var. capitata L.)Abstract
Afield experiment to study the effect of organic and inorganic sources of nitrogen on various physiological parameters of cabbage was conducted at Horticulture Farm, SKN College of Agriculture, Jobner. Results showed that the number of leaves, leaf area, photosynthesis, transpiration, stomatal conductance and chlorophyll content increased significantly with the integrated application of nitrogen as compared to control. The highest values for these parameters were recorded with the application of nitrogen 50% through urea + 50% through vermicompost. The yield increased maximally and significantly when nitrogen was supplied as 50% through urea + 50% through vermicompost. It is concluded that the application of 50% nitrogen through urea + 50% nitrogen through vermicompost registered a significant higher values of physiological parameters in cabbage which was followed by 50% nitrogen through urea + 50 % nitrogen through poultry manure.
