Field experiments wefe conducted to evaluate the efficacy of Teprosyn (Zn and P) formlliations on the yield, growth and yield attributes of sunflower. The salient findings emanatted from the study are: Seed treatment with 130% Zn-P formulqtidn significantly increased the growth. yield and yield attributes of sunflower crop. Though this treatment maintained its superiority, it was on par with soil application of 5.5 kg Zn ha−1. The treatments exerted a non-significant influence on the P and Zn availability in post harvest soil. The Zn uptake by grain and straw of sunflower crop revealed a similar trend as that of yield and yield parameters.
