“…Because of their level of prosperity and their easy access to credit, the farmers in S1 were willing to pay high prices for very efficient imported structures/improved structures with a loss rate of less than 5%. These results are consistent with the work of Bhandari and et al [69], which shows that improved crop storage favors the retention of quality with lower moisture content for year-long storage of maize. Difficulties in obtaining and collecting local materials to construct the structures (long distance or transport and scarcity of some materials) can limit the use of such structures [54,56,58].…”

Farmers’ Willingness to Pay for New Storage Technologies for Maize in Northern and Central Benin

The aim of this study is to identify the attributes of storage structures sought by maize producers based on a choice experiment. The experimental processes took place in the maize production areas of northern and central Benin. The sample consisted of 365 maize farmers (80.55% male and 19.45% female) randomly selected from 40 villages. Data were collected and analyzed using a latent class logit model to study the heterogeneous preferences of the key attributes of storage structures. The results show that men and women are eager to change their current practices and to adopt new storage technologies. The study identifies four potential producer segments, including three large-farmer segments that have access to credit and are particularly attracted to structures related to metal silos. Of those three segments, two are also attracted to improved traditional silos. Another segment of poor farmers, who do not have access to credit, prefer to have a very efficient structure (loss rate of less than 5%) that is designed with local materials. This study suggests that knowledge of the heterogeneity of preferences, as well as the preferred attributes, is important for the development and dissemination of better technologies by agribusiness firms, institutions and policymakers.

“…Seeds of many crops retained viability when stored in a metal bin, super grain bag, and PICS bag, etc. (Bhandari et al, 2018). In sealed containers, dry seeds with 5-7% moisture content retained high germination both at low (-15 to 5 0 C) and at high (25 0 C) temperatures (Doijode, 2001).…”

“…Seed is the principle factor that greatly affects the production and productivity of crop (Shrestha & Shrestha, 2017).Quality seed is considered as the basic, critical, and cheapest input for enhancing productivity and increasing higher net monetary returns per unit area (Hemming et al, 2018).Investment in other costly inputs such as fertilizer irrigation, plant protection will not be remunerative without the use of the quality seed. Inappropriate storage conditions such as seed moisture and storage structures often result in low seed germination, seed deterioration, and loss of viability (Bhandari et al, 2018). The loss of viability of seeds also associate with genetic damage (Pradhan & Badola, 2012) and the degree of damage depends on seed storage condition (Santos et al, 2016).…”

One of the main causes of food insecurity is the timely unavailability of quality seeds for smallholder farmers in developing countries. Improved storage technologies are effective in reducing storage losses. Thus, the objective of this research is to assess the traditional and emerging seed storage structures/materials for the maintenance of seed qualities. The effect of different storage conditions (moisture content of seed at the time of storage, i.e. 12±0.15% and 13.5±0.18%; storage containers such as metal bin, earthen pot, Purdue Improved Crop Storage (PICS) bag, and jute bag) on seed qualities of maize were assessed. The seed was collected from Chitwan, Nepal and a laboratory experiment was conducted at the central seed testing laboratory, seed quality control center (SQQC), Hariharbhawan, Lalitpur. The experiment was done using a two-factor complete randomized design in a four replicates design. Data regarding the seed qualities (seed moisture percentage, germination percentage, root and shoot length, and vigor index) just before store and also at 45, 90, 135, 180, and 240 days after storage (DAS) was performed as per the standard followed by International Seed Testing Association (ISTA). The germination percentage, root, and shoot length decreased with increasing storage duration. The seed stored in the higher moisture level had significantly higher seed moisture throughout the storage duration. Seed stored in the traditional structures (jute bag and earthen pot) had lower seed moisture at 120 and 180 DAS. The seed stored at lower moisture resulted in a higher germination percentage, long root, and shoot length. Up to six months of storage germination of maize seeds stored in the earthen pots, PICS bag, and Jute bags were statistically similar. The traditional storage structures are equally effective for the maintenance of seed quality of maize.

“…Traditional structures and woven bags have higher losses due to pests, leading to grain damage and loss of germination [32,33]. Insects caused the most damage followed by rodents, as found in another study in Nepal [13].…”

“…Hermetic storage methods are viable chemical-free alternatives to traditional methods and pesticides used for grain storage among smallholder farmers [33,44]. They effectively control pests of stored products, maintain seed quality, improve food security, and increase the income of smallholder farmers [32,33,36,45].…”

On-Farm Grain Storage and Challenges in Bagmati Province, Nepal

Farmers in Nepal lose up to one-third of stored grain to pests and diseases. This results in food insecurity and loss of income. To mitigate these losses, farmers use several approaches including pesticide applications on stored grains. We interviewed 241 farmers in Bagmati Province, Nepal, to assess the current on-farm grain storage practices and challenges to improve postharvest management. The results show that rice was the most stored crop (median 1150 kg). About half of farmers stored for at least nine months and grain was mainly used for home consumption. Grain was stored by 66.5 and 69.8% of farmers in granaries (rice) and plastic drums (legumes), respectively. Insects were the most important challenge during storage, and farmers used pesticides to control them. Farmers were more likely to use insecticide on grain (p = 0.000) if they stored rice, used traditional granaries, and had insect damage during storage. The use of improved storage methods (e.g., hermetic bags) was very low for rice (3.5%). There is a need to improve on-farm grain storage by disseminating storage innovations to address postharvest challenges in important crops such as rice.
