Effect of Organic Nitrogen Sources Along with Urea and Bioagents on Growth, Yield and Quality of Cabbage (Brassica Oleracea var. Capitata)

A field experiment was undertaken to study the efficacy of biocomposts on yield and quality of cabbage. Observations during investigation for stalk length, number of weight of non wrapper leaves, leaf area index, net head weight, core volume, yield per hectare, ascorbic acid content, chlorophyll content, photosynthesis and disease incidence were recorded. Highest yield of heads of 415.83 q ha⁻¹ was obtained in treatment where 75 percent of the recommended N was supplied through FYM inoculated with Pseudomonas fluorescens and 25 per cent of balance N through urea. The higher yield of heads in treatment was obtained due to more weight of heads. The above treatment also showed maximum ascorbic acid, chlorophyll content along with highest rate of photosynthesis. In general, Trichoderma harzianum inoculated biocompost showed better control of Rhizoctonia solani in the study.
