EFFECT OF LAND CONFIGURATION, PLANT POPULATION AND NITROGEN MANAGEMENT ON PRODUCTIVITY OF SWEET CORN IN VERTISOL
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 61
Abstract
A research trial was conducted at Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Agronomy farm on "Effect of land configuration, plant population and nitrogen management on productivity of sweet corn" during Kharif season of 2010-11 and 2011-12. The experimental site has semi-arid tropical climate and Vertisol soil. The growth, yield attributes, yield, quality and economics of the sweet corn were significantly superior with the sowing of sweet corn on ridges and furrow with plant population of 55556 plants ha-1 (60 x 30 cm2) along with 100 percent N through inorganic fertilizers to sweet corn. The highest GMR, NMR, B:C ratio was recorded with 100 percent N through inorganic fertilizers over flat bed sowing, 45 x30 cm spacing (74074 plants per hectare) and integrated nitrogen management at 75% N through inorganic fertilizer+ 25% N through vermicompost, 50% N through inorganic fertilizer + 50% N through vermicompost and vermicompost @ 2.5 t per hectare. The same trend was reported about total nitrogen uptake during both the years.
