Seed yield, quality and nutrient uptake of groundnut (Arachis hypogaea) as affected by integrated nutrient management in mid hill altitude of Meghalaya, India.

摘要

A field experiment was conducted during kharif seasons of 2005 and 2006 to study the effect of bio-organics and inorganic sources of nutrient supply on quality seed production of groundnut in mid hill altitude of Meghalaya. Treatments comprised of four biofertilizers and seven organo-inorganic sources of nutrient supply were tested in split-plot design with three replications. Maximum seed yield and seed quality were recorded with combined inoculation of Rhizobium+PSM followed by individual inoculation of Rhizobium and PSM. Application of lime @ 500 kg/ha+FYM @ 10 tonnes/ha+50% NPK recorded highest seed yield and seed quality attributes. Seed inoculation with Rhizobium+PSM in the presence of lime+FYM and 50% NPK improved seed yield and nutrient uptake of groundnut. Highest net return and benefit cost ratio was observed with combined application of Rhizobium+PSM and lime+FYM+50% NPK.
