Abstract:
A Field trial was laid out during Zaid 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of investigational plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36%), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha).The treatments consist of two levels of sulphur soil application and four levels of boron, with a control treatment respectively. The experiment was laid out in randomized block design with nine treatments each replicated thrice. The result showed that viz.: Plant height (126.47 cm) and recorded considerably higher with application of 40 kg/ha Sulphur + 1.5 kg/ha Boron. Number of leaves per plant (21.52) was recorded significantly higher with application of 40 kg/ha sulphur + 1.0 kg/ha boron. Whereas, dry weight (13.16 g/plant), maximum crop growth rate (4.84 g/m²/day) at 30-45 DAS interval and also, relative growth rate (0.039 g/g/day) at 30-45 DAS interval recorded significantly higher application of 40 kg/ha sulphur + 0.5 kg/ha boron Capitulam diameter (14.86 cm), number of seeds per capitulam (333.43), seeds yield (1429.28 kg/ha), stover produce (2476.33 kg/ha) and oil content (41.5%) recorded considerably greater with the application of 40 kg/ha sulphur + 1.5 kg/ha boron.
