Abstract

A trial was executed during Zaid season of 2021, at crop research farm of Department of Agronomy at Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj with the objective to study effect of biofertilizers and levels and sources of sulphur on growth, yield and oil content of sunflower (Helianthus annuus L.) under Randomized block design comprising of 9 treatments, with 2 different levels of sulphur from 2 different sources along with 2 different biofertilizers. The treatment T6 has recorded maximum plant height (134.90 cm) at 80 DAS, RGR of 0.24 g/g/day, highest number of seeds in capitulum 375.33, test weight (39.20), grain yield (1495.67 kg/ha), stover yield (3255.33 kg/ha). While highest leaves (23.40) were reported by treatment T₇ and oil content (42.26%). Treatment T8 has recorded maximum Crop growth rate (3.43) at 20-40 DAS and Harvest index (35.83). Treatment T5 has recorded maximum dry weight of 13.02g at harvest. Treatment T5 has recorded maximum gr
