Rice Seedling, Vegetative Growth and Vigour as Influenced by Seed Storage Period
The main problem affecting productivity involves lack of proper information on best storage time, use of poor quality seed, varietal admixtures which has contributed to low yields. The study assessed the effects of storage on seedling characters of rice in Kirinyaga County. Five varieties were used to produce seedlings after storage for 1,2,3,4,5 and 6 months respectively. The seedlings were transplanted into fields in a Randomized Complete Block Design using 5*6 factorial arrangements. Data was collected on root length, shoot length, germination, tillering, days to 50% flowering date, plant height at maturity. blade length and blade width. All the data were analyzed using GENSTAT statistical package add version and copyright host organization, and means separated using Fisher’s Protected LSD at 5% significant level. There was a significant effect of storage time on germination, with 4 months giving the highest seedling vigor index (673.6), height at 1 month after transplanting (73.3cm), height at maturity (72.3cm) and 3 months giving the highest days to flowering (58.87) The interaction between storage time and genotype on was significant, with genotype B217 stored for 3 months leading in height at one month after transplanting (87.7), height at maturity (91.8cm). The present study indicates that interaction between storage time and variety has an effect on seedling growth.
