Changing pattern of moisture content and other quality of wheat seeds was studied under on-farm condition at high, mid and low hills, and under six different storage structure conditions. The study revealed that the relative increase in moisture content of wheat seeds may go as high as up to 50 and relative decrease in 1000 grain weight and germination percentage may go even up to 14 and 78 respectively under on-farm condition. Considering the changing pattern of moisture, insects, 1000 grains weight and germination percentage of wheat seeds jute bag with inner plastics linning and tin were the best storage structure for safe storage of wheat seeds. It was mainly because they do not allow the moisture to enter inside the structure from the surrounding. The relative decrease in germination percentage of wheat seeds in these structures was only 5 (jute bag with inner plastics lining) and 23 (tin) whereas it was about 80 in rest of the structures. In another study nine different indigenous pesticidal treatments were studied with an objective of screening the best indigenous pesticides for safe storage of wheat seeds. Bojo (Acorus calamus) was found the most effective pesticides against storage pests of wheat seeds. Wood ash and mustard oil were found to be promising and rest of them were ineffective to control the storage pests.
