Investigating the effect of physical storage conditions on rice viability.

Abstract

The present research was carried out to investigate the effect of physical storage conditions (temperature, relative humidity and grain moisture content) on viability of rice seed for two months of storage in, the laboratory of national crop resource research institute during February -April 2015. Temperature, relative humidity moisture content and germination capacity was. recorded throughout the storage period. Polyester bags was used as the packing material, the moisture content and germination capacity was studied as seed temperature and relative humidity changes with the increase of storage duration at initial moisture content of 10%, 13% and 16%. Desk study, consultations and discussions and laboratory tests were used in data collection and data analysis done by using ANOVA and Microsoft Excel. The rice viability was found high with 10% initial moisture content package followed by 13% initial moisture content and lowest from 1 6% initial moisture content package with in the progress of storage period.
