Moisture content, mould growth, insect infestation, damage, seed and food utilizability of NERICA variety of Paddy rice from Baddegi were investigated during storage in inert-atmosphere-metal-silo at Nigerian Stored Products Research Institute, Ibadan over 24 months period. In the 24 months storage trial of paddy rice, the low moisture content (7.0 ± 0.0%), mould growth detection frequency (0%), insect infestation (0%) and damage (2%) at on-set of storage were maintained (to maximum moisture content of 8.6%, mould growth frequency of 0% and insect infestation of 0% in this study), but the high germination rate (88.2%) at on-set of storage was maintained high (≥85%) only for 3 months in storage. After 3 months’ storage of paddy rice in Inert-Atmosphere-Metal-Silo, rapid decrease in germination rate down to 22% by the 12th month of storage was observed. However, the high acceptability of the stored paddy rice (8) as scored by processors or as desired on sale in markets by house wives for food were maintained in the 24
months storage. The limited mould growth, control of insect infestation and limited storability of paddy rice for seed in this silo at Ibadan have been discussed, with recommendation for caution in the use of the silo for long term storage of paddy rice for seeds in Nigeria in the present state of design, construction and accessory provisions. That, an effective cooling system would rather be required to enable prolong storage of paddy rice in Inert-Atmosphere-Metal-Silo for seeds.
