Effect of different fertility levels on growth and yield of rabi sorghum (Sorghum bicolor L. Moench) genotypes under receding soil moisture environment

Résumé fourni par la source

A field experiment was conducted to study the “Effect of different fertility levels on growth and yield of rabi sorghum genotypes under receding soil moisture environment”during rabi2021-22 at AICRP on Sorghum, Main Agricultural Research Station, Dharwad (Karnataka). The experiment was comprising of four fertility levels and eight genotypes laid out in split plot design with thirty two treatment combinations and two replications.The data revealed that, application of 100% RDF(50:25:0 kgNPK/ha) recorded significantly higher plant height (239 cm), Panicle weight (96.8g), grain weight/panicle (68.7 g), 1000-grain weight (30.5 g), grain yield (36.28 q/ha), fodder yield (6.57 t/ha), gross returns (Rs.99702 /ha), net returns (Rs.61119 /ha) and B: C ratio. SPV-2644 gave significantly higher grain yield (40.81q/ha) fodder yield (7.42t/ha), gross returns (Rs.111312/ha),net returns (Rs.74339/ha) and BC ratio (2.95) compared to checks (CSV-29R, CSV-26,CSV-22R and M35-1) followed by SPH-1897.
