Efficiency of Storage Device for Long term Storage of Cowpea Seeds

A study was conducted for the assessment of an appropriate storage device for long term storage of cowpea seeds. Cowpea seeds were stored in four different containers viz. tin container, polythene bag, earthen pot and gunny bag for six months at room temperature. Samples were taken out at monthly interval beginning from the first month of storage to determine the moisture content, germination percentage, vigor index and different fungi associated during storage. The seed moisture content and prevalence of fungi associated during storage were found highest in gunny bag resulting in lowest germination percentage and vigor. Fungal contamination and moisture content increased and seed germination and vigor decreased with the increase in storage period. But seeds stored in tin container maintained excellent germination percentage and vigor index as the moisture content and fungal contamination were less compared to other storage devices throughout the storage period. Comparing all the storage devices, it was found that tin container is the best and secure device for long term storage of cowpea seeds.

Assessment of appropriate storage device for long term storage of cowpea seeds was carried out under in vivo condition.

Four different devices viz. tin container, polythene bag, earthen pot and gunny bag was used for the study and cowpea seeds were stored in the devices for six months.

Among the storage devices, tin container was found best for storage of cowpea seeds followed by polythene bag, earthen pot and gunny bag.
