Effect of integrated nutrient management on yield of black pepper

The nutritional need of black pepper is unique for its proper spike setting, uniform berry formation, ripening etc. An experiment was conducted with the objective of studying the effect of integrated

Nutrient management system on the yield of black pepper. The inorganic fertilizers viz., urea, Rajphos, muriate of potash was used as source of nitrogen, phosphorus and potassium, respectively. The experiment was laid out in randomized block design with five treatments replicated four times. Results revealed that application of 100% Recommended dose of fertilizers (50:50:100 g NPK/Vine/year) + Azospirillium + phosphate solubilizing bacteria (25g each) + Arbuscular Mycorrhizal Fungi (50 g) has showed a superior performance on yield and yield attributing components.
