Influence of fertility levels on growth and yield attributes of different wheat (Triticum aestivum L.) varieties under semi-arid conditions of Rajasthan

A field experiment was conducted during 2024-25 at Agronomy Research Farm, School of Agricultural Sciences, Jaipur National University, Jaipur, Rajasthan to evaluate the “Effect of Fertility Levels on Growth, Yield and Quality of Different Wheat (Triticum aestivum L.) Varieties Under Semi-Arid Conditions of Rajasthan”. The experiment was laid out in split plot design with three replications. The experiment consists four fertility levels viz.; control, 75% RDF, 100% RDF and 125% RDF as main plot and three varieties viz; RAJ 3077, RAJ 3765 and RAJ 4083 as sub plot. The significantly higher growth parameters viz., plant height, dry matter accumulation (DMA), crop growth rate (CGR) and relative growth rate (RGR) and yield attributes and yield i.e. the maximum ear length (10.35 cm), number of grains ear-1 (57.70), 1000-grains weight (48.35 g), grain yield (5643 kg ha-1), straw yield (8233 kg ha-1), biological yield (13877 kg ha-1) and harvest index (40.62%) of wheat were obtained with the application of 125% RDF followed by 100% RDF. However, Among the varieties, the variety RAJ 3077 recorded significantly higher growth parameters viz., plant height, dry matter accumulation (DMA), crop growth rate (CGR) and relative growth rate (RGR) and yield attributes and yield i.e. the maximum ear length (10.23 cm), number of grains ear-1 (57.00), 1000-grains weight (47.77 g), grain yield (5458 kg ha-1), straw yield (8094 kg ha-1), biological yield (13552 kg ha-1) and harvest index (40.31%) of linseed.
