Impact of Sulfur on Sunflower Growth and Yield

Abstract

The use of Sulphur (S) is known to have a significant effect on the growth and yield components of Sunflower (‘Helianthus annuus’ L.). From March to May, the Kharif season from 2022 was conducted at Amir Muhammad Khan Campus, The University of Agriculture, Peshawar in order to analyses S’s effects on sunflower with varying levels of Sulphur 0, 10, 20, 30 kg ha⁻¹. A randomized complete block design was followed with three replicates of sunflower crops across the region. Results showcased the best growth parameters with 30kg S ha⁻¹, early emergence on day 10 and oil content of 45.38%, seed weight oil content of 60.39g, plant height of 156.66cm. Furthermore, all 30 ha were the optimal yielding conditions with Michigan S K Port received values of grain yield and biological yield peaking at 1076 alongside 4310 Kg ha⁻¹ becoming the new regional record. Overall, S was showcased with the fullest potential regarding the sunflower yield, with 30 kg S has recommended for the Mardan region.
