Disease and Yield Reaction of Some Groundnut Varieties to Benomyl Application

Abstract

The study revealed varietal reaction of four groundnut varieties (i.e Rmp91, M554.76, Ex-Dakar and R. R.B) to Benomyl fungicide, in controlling leaf spot in the varieties. A2 x 4 factorial experimental design, in which fungicide treatment and control were applied to main plots and varieties to subplots in three replicates, was adopted. Data collected based on leaf spot infection and pod yield were subjected to Analysis of variance and Duncan Multiple Test. The result indicated that the groundnut exhibited significantly differential varietal response (p>3.40) in leaf spot reaction and pod yield to benomyl application. It is recommended that RM91 groundnut variety produced for pod yield with benomyl application is more profitable than cultivation of the remaining three varieties with or without benomyl application.
