“…The popular hermetic bags are Super Bags (GrainPro, Washington, D.C., USA) and Purdue Improved Crop Storage (PICS) bags, and are being used in >80 countries to protect grains, legumes, and industrial commodities [ 229 ]. A PICS bag is comprised of a double layer of high-density polyethylene (HDPE) liners inside of a woven bag, while a Super Bag consists of a single HDPE layer to control post-harvest losses in cereals [ 230 ]. In a recent study conducted at agro-climatic conditions of Pakistan, quality of quinoa seeds stored in hermetic bags at 8% initial seed moisture content is preserved in terms of higher germination and vigor and negligible seed deterioration compared with traditional storage under diverse ambient conditions.…”

Quinoa is a crop originating in the Andes but grown more widely and with the genetic potential for significant further expansion. Due to the phenotypic plasticity of quinoa, varieties need to be assessed across years and multiple locations. To improve comparability among field trials across the globe and to facilitate collaborations, components of the trials need to be kept consistent, including the type and methods of data collected. Here, an internationally open-access framework for phenotyping a wide range of quinoa features is proposed to facilitate the systematic agronomic, physiological and genetic characterization of quinoa for crop adaptation and improvement. Mature plant phenotyping is a central aspect of this paper, including detailed descriptions and the provision of phenotyping cards to facilitate consistency in data collection. High-throughput methods for multi-temporal phenotyping based on remote sensing technologies are described. Tools for higher-throughput post-harvest phenotyping of seeds are presented. A guideline for approaching quinoa field trials including the collection of environmental data and designing layouts with statistical robustness is suggested. To move towards developing resources for quinoa in line with major cereal crops, a database was created. The Quinoa Germinate Platform will serve as a central repository of data for quinoa researchers globally.

“…Increasing damages were observed in the Super Grain Pro bag as the storage time increased, especially after 18 months of storage. This might be due to that the hermetic bags are not perfectly impermeable to oxygen and moisture, or bag condition during storage (invisible damage by insects, or any other form) might have contributed to permeability of the bags (Kiobia et al., 2020). Baoua et al (2014) also suggested that the high‐density polyethylene (HDPE) layers are not perfect oxygen barriers but greatly reduce the rate of oxygen exchange with the surrounding environment.…”

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

et al. 2023

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.

“…Most of the surveyed farmers opened their HSTs periodically after sealing to obtain grains either to be used as food or to sell for income to meet their household needs. While the opening of hermetic storage interrupts the herme- ticity principle, sealing the container shortly after has been shown not to significantly impact grain quality [56].…”

Post-harvest storage losses (PHLs) remain significant in Sub-Saharan Africa (SSA) due to several factors mainly insect pests and molds. Hermetic storage technologies (HSTs) are being promoted to address these storage losses. In Uganda, HSTs were first introduced in 2012. However, its use among farming households remains low today. Data were collected from 306 smallholder farmers from four districts of Northern Uganda using a pre-tested semistructured questionnaire to understand their knowledge, use, and constraints to the adoption of hermetic storage. A multivariate Logit regression model was used to find the significance of the factors affecting adoption. Results showed low awareness and use of hermetic storage among smallholder farmers. Only 53.3% of the interviewed farmers were aware of the use of hermetic storage for grain storage. The SuperGrain bag was the most known form of hermetic storage (35.3%), followed by the Purdue Improved Crop Storage (PICS) bag (34.9%), metallic silo (15.5%), and plastic silo (14.4%). Hermetic storage use was even lower as only 17.6% of the surveyed farmers were using one or more forms of hermetic storage to store their grains. Insect pest management without chemical insecticides was the main reason (83.1%) for hermetic storage use. About 75.5% of those aware of hermetic storage had received training in the technology. Hermetic storage use in farming households led to improved food availability, household income, and nutrition. Lack of local availability (50.2%), high costs (37.8%), and inadequate knowledge (6.
