Cocoon Storage: A Better Alternative to the Use of Inorganic Insecticides/Pesticides in Middle Level and Large Scale Storage, in the Tropics
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 10
Abstract
This paper reviews the economics and efficacy of hermetic cocoon storage as a preferred alternative to use insecticides and pesticides for middle level and large scale storage of cereal grains, paddy crops, oil seeds and pulses in the tropics. Also assessed and evaluated is the ability of hermetic storage cocoon to maintain the quality attributes of stored grains, and control most of the causative agents, or issues responsible for enormous storage losses, as far as grain storage is concerned in the developing countries. White coloured hybrid 9021 maize stored in cocoon was evaluated for physical and proximate characteristics for a period of 2 years. Grain samples were taken randomly at inception of storage and on quarterly basis during storage. Data collected was analysed using Statistical Package for Social Sciences (SPSS) and Duncan multivariate test were used to determine how significant the changes that occurred in the grain within the period. The variables evaluated were both quality and mass characteristics which includes Moisture content wet basis (MC), Bulk density( BD), Insect damaged grains (ID), Mould infested grains (MD), Cores and fines(FM), Crude protein (CP), Crude fat content (CF), Ash content (AS), Carbohydrate value (CV), Energy value (EV), and Germinability (G). Most of the physical properties of the grains remained almost unchanged. The proximate characteristics, depreciated, but most variables were not significant within the 2 years of storage. Only carbohydrate and energy value appreciated slightly within the duration. The general quality of stored grain was excellent and above average within the acceptable standard and limit for stored cereal grains.
