Effect of organic sources of nitrogen on physiological parameters of king chilli (Capsicum chinense Jacq.) under poly house condition

Abstract

A study was conducted in rabi season 2019-20 in the poly-house, Department of Horticulture, CAU, Imphal to observe the effect of organic sources of nitrogen on net assimilation rate, relative growth rate and plant growth efficiency of king chilli (Capsicum chinense Jacq.) under poly house condition. The layout of the experiment was RBD (Randomized Block Design) with three replications under 8 different treatments. Results of the present experimentation revealed that the application of 100% RDF (T8) registered significant values for net assimilation rate (0.0232 g/m2/day), relative growth rate (0.0574 g/g/day) and plant growth efficiency (57.41%) at 60-90 DAT stage. However, among the organic sources, application of 100% RDN through vermicompost (T3) had significant effect on the physiological parameters of the crop which was comparable with that of inorganics treatment.
