Abstract
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 significantly higher
in sole foxtail millet with recommended organic nutrient management practices without tree
components (45.67, 12.77 and 55.90 kg ha -1 , respectively) when compared with all the treatments
with tree association. No organic manurial treatment recorded significantly lower nitrogen,
phosphorous and potassium uptake (10.55, 4.95, and 22.18 kg ha -1 , respectively) at harvest of the
crop. While, with tree association in agroforestry system, available soil nitrogen, phosphorus and
potassium were significantly higher by application of FYM + poultry manure + panchagavya
alternated with vermiwash spray (242.80, 27.60 and 311.52 kg ha -1 , respectively) followed by
application of FYM + poultry manure + vermiwash spray (235.17, 24.93 and 288.61 kg ha -1 ,
respectively) which in turn showed significant superiority over no organic manurial treatment,
application of FYM and FYM + vermiwash spray.
