Abstract

Average farmers’ uncensored beliefs
toward Tillage and manure practices in the Sahel are the notions that informed
our decision for this study in northern Yobe State, Nigeria. Its objectives
were to determine the effects of tillage depths, manure types, and the nature
of their relationships with some performance indices and Grain Yield of Cowpea
(Vigna unguiculata L.). Designed on a Split Plot; Tillage depth (Zero, Shallow
and Deep tillage) was assigned to main plot while Manure type (No Manure, Cow Dung
and Poultry Manure) was assigned to subplot. Plots treated with PM showed the highest positive response compared to other
manures in terms of cowpea growth parameters and Grain Yield. Zero Tillage performed
better than other tillage depths. It was concluded that Interaction between ZT and
PM proved to be the best combination to improve Cowpea farmers Yield and Above Ground
Biomass for the farmers and their livestock in Sahel Savannah. Pearson’s
Multiple Linear Correlation indicated high positive relationship between OM and
all the Cowpea parameters measured (r ≥ +0.65 ≤ +0.92). Tillage depth was found
to significantly correlate with Pod length (r = -0.36*) and Single Pod Weight
(r = -0.40*) at P ≤ 0.05 in a negative passion.
