Effect of Sulphur and Zinc levels on growth and yield of safflower (Carthamus tinctorius L.)

Abstract

A field experiment was conducted during Rabi season 2020 at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad (U.P) to determine the Effect of Sulphur and Zinc levels on growth and yield of spineless safflower. The experiment was laid out in Randomized Block Design, with nine treatments which consisted of viz., T1: Sulphur 0 kg/ha+ Zinc 0 kg/ha, T2: Sulphur 0 kg/ha + Zinc 15 kg/ha, T3: Sulphur 0 kg/ha + Zinc 30 kg/ha, T4: Sulphur 30 kg/ha + Zinc 0 kg/ha, T5: Sulphur 30 kg/ha + Zinc 15 kg/ha, T6: Sulphur 30 kg/ha + Zinc 30 kg/ha, T7: Sulphur 45 kg/ha + Zinc 0 kg/ha, T8: Sulphur 45 kg/ha + Zinc 15 kg/ha, T9: Sulphur 45 kg/ha + Zinc 30 kg/ha which were replicated thrice. The results revealed that treatment combination of Sulphur 45 kg/ha + Zinc 30 kg/ha had shown significant increase in growth parameters viz., plant height (101.71cm), number of branches (22.37), plant dry weight (42.62 g), and yield attributes viz., heads per plant (21.33), seeds per head (22.67), Test weight (56.67 g), seed yield (1522.7 kg/ha) and stover yield (5888.24 kg/ha) and harvest index (25.86 %). Therefore it's concluded that combination of Sulphur 45kg/ha + Zinc 30 kg/ha recorded significantly higher value in all the parameters as compared to other treatment combination.
