“…The loss of germination recorded in the control treatments was almost certainly due to seed-embryos destruction by the insects. PICS bags performed better than Supergrain bags (another type of hermetic bag available to farmers in developing countries) for storing groundnuts ( Harish et al., 2014 ). Supergrain bags enabled the development of C. serratus with a weight loss of 66.9% and 75.9% after 6 months of storage for shelled and unshelled groundnuts, respectively.…”

We conducted an experiment in Niger to evaluate the performance of hermetic triple layer (Purdue Improved Crop Storage- PICS) bags for the preservation of shelled and unshelled groundnut Arachis hypogaea L. Naturally-infested groundnut was stored in PICS bags and woven bags for 6.7 months. After storage, the average oxygen level in the PICS bags fell from 21% to 18% (v/v) and 21%–15% (v/v) for unshelled and shelled groundnut, respectively. Identified pests present in the stored groundnuts were Tribolium castaneum (Herbst), Corcyra cephalonica (Stainton) and Cryptolestes ferrugineus (Stephens). After 6.7 months of storage, in the woven bag, there was a large increase in the pest population accompanied by a weight loss of 8.2% for unshelled groundnuts and 28.7% for shelled groundnut. In PICS bags for both shelled and unshelled groundnuts, by contrast, the density of insect pests did not increase, there was no weight loss, and the germination rate was the same compared to that recorded at the beginning of the experiment. Storing shelled groundnuts in PICS bags is the most cost-effective way as it increases the quantity of grain stored.

“…An increased use of these chemicals has, however, resulted in resistance among targeted species and, thus, reduced their effectiveness [74,75]. In addition, adulteration of these pesticides within the supply chain, associated environmental and health-related concerns due to unwanted pesticide exposure to smallholder farmers, and higher costs for marketing new chemical pesticides have limited the emergence of new chemicals effective for grain storage [74,[76][77][78].…”

An Overview of the Post-Harvest Grain Storage Practices of Smallholder Farmers in Developing Countries

2018

Grain storage loss is a major contributor to post-harvest losses and is one of the main causes of food insecurity for smallholder farmers in developing countries. Thus, the objective of this review is to assess the conventional and emerging grain storage practices for smallholder farmers in developing countries and highlight their most promising features and drawbacks. Smallholder farmers in developing countries use conventional grain storage structures and handling systems such as woven bags or cribs to store grain. However, they are ineffective against mold and insects already present in the grain before storage. Different chemicals are also mixed with grain to improve grain storability. Hermetic storage systems are effective alternatives for grain storage as they have minimal storage losses without using any chemicals. However, hermetic bags are prone to damage and hermetic metal silos are cost-prohibitive to most smallholder farmers in developing countries. Thus, an ideal grain storage system for smallholder farmers should be hermetically sealable, mechanically durable, and cost-effective compared to the conventional storage options. Such a storage system will help reduce grain storage losses, maintain grain quality and contribute to reducing food insecurity for smallholder farmers in developing countries.

Comparison of hermetic bags with polyethylene‐lined polypropylene bags for prolonged storage of faba bean (Vicia faba L.) seeds in Ethiopia

Poor storage facilities expose seeds to deterioration, resulting in low seed quality under a prolonged storage time. We compared the performance of five bag types: Two hermetic bags (Super GrainPro bag [SGB] and Purdue Improved Crop Storage bag [PICS]), with three non‐hermetic bags (woven polypropylene bag lined with polyethylene [WPP lined with PE], polypropylene bags [PP], and jute bags) for the storage of faba bean seeds for 24 months. Faba bean seed quality was assessed under ambient conditions after 0, 6, 12, 18, and 24 months of storage. Parameters investigated include seed moisture content, thousand seed weight, germination percentages, vigor index I and II, speed of germination, percentage of insect‐damaged seed, and insect counts. Results indicated that there was a significant (P ≤ 0.01) interaction of bag types and duration for all tested parameters. Hermetic bags and WPP lined with PE maintained germination percentage above 90% during 12 months of storage. The vigor index remained above 1600 mg% for hermetic bags and WPP lined with PE during 12 months of storage. However, non‐hermetic bags exhibited a rapid drop in vigor index beginning from 6 months of storage. Hermetic bags and WPP lined with PE allowed minimal insect breeding and hence decreased the seed damage caused by insects. The present results demonstrated that in addition to the PICS bags and SGB, the WPP lined with PE can be used for short‐period storage for up to 12 months without incurring a significant loss of seed quality. Hence, we recommend the introduction of WPP lined with PE as faba bean seed storage technique under conditions where hermetic bags are inaccessible to resource‐poor farmers.
