Variation in grain damage of green gram stored in hermetic and other bags

Asha Kumari and Mukesh Shrivastava
A study has been conducted to see the effect of storage duration and other factors on grain damage in Green gram stored in hermetic and other bags. Green gram (Vigna radiate) grains were procured from local market, cleaned and graded by two screen cleaner-cum-grader. Storage study was conducted by storing large sized green gram grains in 4 types of bags (jute, plastic, polythene, hermetic) without and with treatment (aluminium phosphide tablets) at 3 different initial moisture contents (12.34, 14.07, 16.04 % w.b.). Total 21 such bags having different treatment combinations were kept in laboratory for 33 weeks. Daily observation of ambient temperature and relative humidity was taken throughout the study period. Weekly observations of moisture content were recorded for 27 (jute bags) to 33 weeks (hermetic bags). It was observed that grain damage goes on increasing with advancement of storage duration across all 21 experimental combinations. The overall variation range for grain damage was found between 2.33 – 78.67 %. Variation was observed more in case of untreated samples as compared to treated samples. Hermetic bags stored green gram was found better with minimum increase in grain damage (2.33 to 20.00 %) even after 33 weeks of storage duration. Statistical analysis through UNIANOVA revealed that initial moisture content emerged as most significant independent variable to affect grain damage. The interaction of bags*imc significantly affected grain damage. Hence the hermetic bag could be recommended for storing green gram safely for longer duration without affecting its quality.
