Abstract

Background: Productivity of sweet corn depends on genetic makeup and adoption of innovative technological interventions viz., planting density, balanced application of organic manures and fertilizers, herbicides etc. Nevertheless, the response to the aforementioned interventions may vary with different locations owing to varied climatic and edaphic and other management factors. Enhancement in productivity can be achieved through adoption of proper planting density and nutrient management as they play a vital role. The present study aimed to evaluate different sweet corn hybrids under varied planting density and nutrient levels for improving the productivity of sweetcorn. 
Methods: Field experiments were conducted during Kharif, 2019 and Kharif, 2020 to evaluate sweet corn hybrids under varying planting density and nutrient levels. The experiments were laid out in a split split plot design. In the main plot, two sweet corn hybrids and in the sub plot, two planting densities and in the sub sub plot, three nutrient levels were tried. Observations on growth, green cob yield and green fodder yield were recorded.
Result: Based on the results of two years of experimentation, it is concluded that MISTHI recorded higher green cob yield (16330 kg ha-1), net return (Rs. 64931/ha) and B:C ratio (2.47) under 60 × 15 cm with 100% RDF (120:60:45 NPK kg/ha). CSCH-15001 recorded relatively lower green cob yield (15649 kg ha-1), net return (Rs. 61291/ha) and B:C ratio (2.38) under 60 × 15 cm with 100% RDF.
