 ABSTRACT

A field experiment was conducted on wheat (Triticum aestrivum L.) during Rabi 2013-14, 2014-15 and 2015-16 at Wheat Research Station, Junagadh Agricultural University, Junagadh- Gujarat. The treatments comprised six levels of potassium (0, 30, 60, 80, 60 & 80 two split (1/2 as basal& 1/2 at 30 day after sowing -DAS kg K2O ha-1) and three levels of sulphur (0,20 and 40 kg Sha-1) were evaluated in Randomized Complete -Block design with four replications. Results revealed that the growth and yields attributes viz., plant height, effectively tiller/m2, No. of spikelet/spike, grain /spike and 1000 grain weight, grain and straw yields and nutrients (N,P,K and S) uptake  increased significantly with increasing levels of K and S individually years  as well as in pooled. Synergistic interaction effect of potassium and sulphur  on grain and straw yield was highest at 60 kg K2O ha-1 and 40 kg S ha-1. The magnitude of increase in grain and straw yield was 38.8 and 23.6 % due to combined application of potassium and sulphur (K60 S40) over control, respectively. Highest net return ( Rs. 56,621) and benefit : cost ratio (2.30) was recorded with the treatment combinations of  K60 S40(60 kg K2O ha-1 and 40 kg S ha-1).

Key words: Potassium, Sulphur, Wheat yields, Nutrients uptake, Economi
