Effect of sulphur levels on growth and yield of different radish varieties in semi-arid region of Rajasthan

Abstract

A field experiment was conducted at Crop Research Farm, School of Agricultural Sciences, Jaipur National University, Jaipur, Rajasthan during Rabi, 2024-25 on sandy loamy soil. The experiment was laid out in Factorial Randomized Block Design, replicated thrice, consisting of twelve treatments four levels of sulphur (Control, 20, 40, and 60 kg/ha) and three radish varieties (Japanese White, Pusa Himani, and White Icicle). Results revealed that application of 60 kg/ha sulphur significantly enhanced growth and yield attributes including maximum fresh weight (294.48 g), dry weight (19.98 g), root length (26.93 cm), maximum root diameter (3.77 cm), maximum fresh root weight (151.52 g) and maximum root yield (460.27 q/ha). Among varieties, Japanese White produced the maximum fresh weight (277.30 g), dry weight (20.05 g), root length (29.83 cm), root diameter (3.64 cm), fresh root weight (151.46 g) and maximum root yield (505.77 q/ha). Research findings suggest that 60 kg/ha sulphur supplementation and selection of Japanese White are most suitable for optimizing yield (520.34 q/ha) of radish in semi-arid regions.
