Effect of Season and Storage Method on Seed Quality of Slender Leaf (Crotalaria Sp.) in Western Kenya

Abstract

Slender leaf (Crotalaria sp.) is an important source of nutrients, income and traditional medicines in Kenya. However, its production is constrained by lack of quality seeds. The aim of the study was to investigate the effect of various storage methods on seed quality of slender leaf and recommend the best method(s) of seed storage to the farmers in Western Kenya. Seeds from various morphotypes of slender leaf that had high germination percentage (90% and above) were stored in Kakamega and Siaya Counties using pots, jars, brown paper bags and polythene bags. Seeds were also stored in the freezer at (at temperature of -20C) at University of Eldoret.Storage period was 3 months. Seed viability and vigour, were determined for each storage method. Data obtained from storage experiments was subjected to ANOVA and T-tests using Statistical Analysis Software (SAS). Season of growth and storage methods significantly influenced seed quality in Kakamega and Siaya. Seeds stored in pots, brown paper bags, jars and freezer had higher seed quality than those stored in polythene bags. It was concluded that in order to obtain high quality seeds farmers should store slender leaf seeds in pots or brown paper bags or plastic jars or freezer. Farmers should avoid storing seeds in polythene bags as it results in low quality seeds.
