Nutrient dynamics in foxtail millet – Melia dubia based agroforestry system under organic production system

Investigation on Nutrient dynamics in foxtail millet-Melia dubia agroforestry system under organic production system was conducted for two years (2018-19 and 2019-20) at the University of Agricultural Sciences, Raichur, Karnataka, India.There were eleven treatments with three replications, laid out in a completely randomized block design.In pooled data, nitrogen, phosphorus, and potassium uptake by foxtail millet at harvest were signi icantly higher in sole foxtail millet with recommended organic nutrient -1 management practices without tree components (45.67, 12.77 and 55.90 kg ha , respectively) when compared with all the treatments with tree association.No organic manurial treatment recorded signi icantly lower nitrogen, phosphorous and potassium -1 uptake (10.55, 4.95, and 22.18 kg ha , respectively) at harvest of the crop.While, with tree association in agroforestry system, available soil nitrogen, phosphorus and potassium were signi icantly higher by application of FYM + poultry manure + panchagavya -1 alternated with vermiwash spray (242.80,27.60 and 311.52 kg ha , respectively) followed by application of FYM + poultry manure + -1 vermiwash spray (235.17,24.93 and 288.61 kg ha , respectively) which in turn showed signi icant superiority over no organic manurial treatment, application of FYM and FYM + vermiwash spray.
