Effect of NPK Micro-dosses on yield, Oil and Protein of Groundnut

Abstract

A field experiment was conducted under rain fed condition for two seasons (2011 and 2012) at two locations in North Kordofan, Sudan at Elobeid Research Station farm and Faris village, to study the effect of NPK micro dose on yield, oil and protein content of six groundnut genotypes with two NPK micro-doses, 0.0 g (control) and 0.6 g per hole. A randomized Complete Block Design with four replications was used. The characters yield and its component, oil % and protein % content were measured. The results of the combined and interaction analysis showed that there were significant (p =0.05) differences were observed for pod yield, hay yield, number of pods per plant, hundred seed weight and maturity, while differences in shelling percentage and harvest index were not significant. The high value of oil content % released by Sodiri variety with NPK treatment and the high value of protein recorded by Gibiesh with NPK treatment. Generally we concluded that the micro doses of NPK improved yield and protein of groundnut.
