Abstract:
In the year 2019-20, a field trial was conducted at the Horticulture farm, College of Agriculture, Rajendranagar, Hyderabad, Telangana. The aim was to investigate the impact of N and K fertigation on the growth of coloured Capsicum hybrids cultivated under shade net conditions in sandy loam soils. The trial encompassed four primary plot treatments representing varying N and K fertigation levels viz., F₁: 50% RDF of N, K (50:0:30), F₂: 75% RDF of N, K (75:0:45), F₃: 100% RDF of N, K (100:0:60) and F₄: 125% RDF of N, K (125:0:75) and three varieties viz., V₁: Indra (green variety), V₂: Orobelle (yellow variety) and V₃: Bombey (Red variety). The experiment was conducted using a split-plot design with three replications. Application of 125% RDNK (15.00 t ha^-1) through fertigation being at par with that of fertigation @ 100% RDNK (13.69 t ha^-1), has significantly outyielded other fertigation treatments. Further, the highest total capsicum fruit yield and water productivity were observed with Indra (V₁) (17.17 t ha^-1; 2.82 kg m^-3) and was significantly superior to Bombey (V₂: 10.23 t ha^-1; 1.68 kg m^-3) and Orobelle (V₃: 9.52 t ha^-1; 1.56 kg m^-3) hybrids.
