Abstract
Seed cotton yield, as well as nitrogen and sulfur uptake by seed and stalk, were higher under due to application of 75% RDN + 25% through FYM and were statistically on par with application of 75% RDN + 25% through neem cake across both years and in pooled data. The effect of sulfur on seed cotton yield, oil content, and N and S uptake by seed and stalk was significant, higher values observed under application of 40 kg S/ha, which was statistically similar to application of 20 kg S/ha treatment in both individual years and pooled analysis. A significant interaction effect of nitrogen and sulfur was observed on seed cotton yield in both years and pooled data, as well as on N and S uptake by seed in pooled results. Higher values of seed cotton yield were recorded under application of treatment combination 75% RDN + 25% through FYM + 40 kg S/ha, which was statistically at par with application of treatment combination 75% RDN + 25% through neem cake + 40 kg S/ha and treatment combination of 75% RDN + 25% through FYM + 20 kg S/ha across all years and pooled results.
