A field investigation was conducted on sandy loam soil of Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during kharif season of 2016, with an aim to study the effect of levels of improved sulphur (S) formulations on growth and productivity of rice grown in Gangetic alluvial of Uttar Pradesh. It was revealed that the growth parameters, yield attributes, yield, and nutrient uptake were significantly influenced by the application of improved S fertilizers. Application of improved S, Gromor Rapid Blue® @ 10 kg acre−1 produced the highest dry matter accumulation, grain weight panicle−1, test weight, and straw yield. Maximum grain yield (4.85 t ha−1) was obtained in 7.5 kg Gromor Rapid Blue® acre−1, which is about 18% higher than the control. In case of uptake of nutrients by grain, highest uptake of N and S was recorded with 10 kg Gromor Rapid Blue® acre−1, and highest uptake of P and K was obtained with 7.5 kg Gromor Rapid Blue® acre−1. According to the study, application of Gromor Rapid Blue® @ 7.5 kg acre−1 is recommended for better growth and yield of rice in soils of Varanasi.
Adoption of improved S formulations for overcoming the challenges of S deficiency
With each successive levels of improved S fertilizers there is enhancement of growth and yield of rice
Highest chlorophyll content, grain yield, and grain P and K uptake were recorded with application of Gromor Rapid Blue® @ 7.5 kg acre−1
