Seed Viability And Oxygen Depletion Rate Of Hermetically Stored Maize Infested By Major Insect Pests

Journal Title: Scientia Agriculturae - Year 2013, Vol 4, Issue 1

Abstract

 Grain moisture content assessment, oxygen depletion rate and seed viability tests were conducted to ascertain the particular type of bag that prolonged germination rate despite infestation by major destructive insect pests. Three storage bags (Triple-layer hermetic bag, Jute and Polypropylene) and three maize varieties (Obatanpa, Abrodenkye and Kamangkpong) were used in this study. A factorial experiment was conducted involving 5 kg of each maize variety with moisture contents between12.5-14%. These were stored in the various bags at laboratory conditions of 32 ±2 oC and 58-88% r.h and a destructive sampling of 54 bags (27 bags for each insect species) was done each month for a 6 month storage period. Oxygen depletion rate was monitored to determine the duration for total depletion of oxygen or to levels that would not support insect survival. The results revealed that both S. zeamais and P. truncatus could feed and breed on all three maize varieties. There was also highly significant difference (p < 0.001) in the bag-insect-variety interaction. Moisture content and seed viability were significantly different (p < 0.001) in the various bags. The study further showed that the triple-layer hermetic bag preserved seed quality and viability much longer than the conventional Jute and Polypropylene bags.
