Defoliation Effects on the Production of Cowpea Pods
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 7, Issue 1
Abstract
In Sudano-Sahelian zone of Chad, cereals are the basis of food. The diversification of this diet requires the introduction of foods rich in protein and minerals and justifies the quantitative improvement of the leaves and seeds of cowpea. The purpose of this study is to determine the period when leaf removal has less impact on pod production. The effect of defoliation on pod production was verified on three pure lines grown in the field. The experimental device is a split plot with three repetitions with the three genotypes that constitute the main treatments and the nine modes of defoliation. The analysis of variance in the collection data shows a significant difference between the average number of leaves per plant and the number of pods per plant depending on the number of leaf samples. The removal of 5 leaves at 40 days after emergence stimulates pod production. This stage seems to be the ideal stage of sampling
