Yield and nutrient uptake of pearl millet (Pennisetum glaucum) as influenced by nutrient management practices under Melia dubia based Agri- silvi system

Abstract

Field experiment was conducted during kharif 2017 and 2018 to study the effect of nutrient management practices on yield and nutrient uptake of pearl millet intercropped in Melia dubia (Agri-silvi system). The experiment consisted of eight treatments and laid out in randomised block design with three replications. The treatments are T1-Control (no fertilizer and manure), T2-100% RDF through normal urea, T3-100% RDF through neem coated urea, T4 75% RD N + 25% N through Poultry manure, T5 75% RD N + 25% N through FYM, T6 75% RD N + Pongamia green leaf manure @ 10 t ha-1, T7 75% RD N + Azotobacter @ 500 g ha-1, T8 Sole crop without trees (100% RDF). Results of the experiment showed that sole crop of pearl millet recorded significantly higher grain yield, stover yield and nutrient uptake followed by 100% RDF through neem coated urea under Melia dubia. Among the integrated nutrient management treatments 75% RD N + Pongamia green leaf manure @ 10 t ha-1 registered higher yield and nutrient uptake of pearl millet compared to other treatments.
