The field experiment was conducted to study the integrated nutrient management on physiological yield and quality of chilli by using four different varieties. The experiment was laid in Split Plot Design with three replications five different treatments including different combinations of organic and inorganic fertilizers i.e. 100% RDF, 75% RDF + 25% vermicompost, 75% RDF + 25% vermicompost + VAM, 75% RDF + 25% vermicompost + Humic Acid, 75% RDF + 25% vermicompost + Azotobacter and four varieties of chilli were used i.e. VS455, SS841, Punjab Tej and Teja. By increasing the potential from all conceivable sources of inorganic, organic, and natural components in an integrated manner, Integrated Nutrient Management proposed to maintain soil fertility and plant nutrients at their most satisfying level for maintaining the preferred productivity. The main elements of INM include fertilizer, organic manures, legumes, agricultural leftovers, and bio fertilizers. The availability of nutrients is a crucial consideration when maximising output in any crop. According to the study, compared to other treatments, an integrated usage of 75% RDF + 25% vermicompost + VAM had the best yield (94.16 q/ha), chlorophyll index (58.84), and ascorbic acid (35.41 mg/100 g) were among the production and quality characteristics that were positively impacted by the treatment. Therefore, it can be said that VS455 and SS841 varieties responded better when integrated usage of 75% RDF + 25% vermicompost + VAM were used in terms of growth, yield, and quality.

Azotobacter, FYM, Humic Acid, vermicompost and VAM

On the basis of results obtained from the investigation it may be concluded that application of 75% RDF + 25% vermicompost + VAM increased the Chlorophyll Index, produced higher fruit yield and enhanced the quality of chilli. So, it may be concluded that VS455 and SS841 variety showed better response in terms of growth, yield and quality when integrated use of 75% RDF + 25% vermicompost + VAM were applied. It may be better option for the formers having adequate resources.
