“…Faced with high rates of potential losses, selling maize at harvest may be an optimal strategy to avoid losses due to pest damage. Although some empirical evidence from Kenya, South America, and Ethiopia indicates that modern storage technologies such as hermetic (airtight) bags, metal silos, and/or chemical protectants may reduce losses from insect damage and thereby improve households’ food and income security, access to these technologies is severely limited, particularly in sub‐Saharan Africa (SSA; Bokusheva et al., ; Gitonga et al., , Tesfaye and Tirivavi, ). Lack of access to effective storage technologies may prevent smallholder households from storing grain at harvest for consumption or sale later in the year.…”

This article estimates how storage losses from mold, insects, and other pests, combined with liquidity constraints, influence a smallholder farm household's decision to store maize on farm after harvest. We analyze panel data from 309 smallholders in Benin covering the 2011 and 2013 harvest seasons. Results suggest that smallholders are driven to sell at harvest time for different reasons, depending on their motivation for storing. In households that report direct consumption as their primary goal for storing maize, liquidity constraints, not storage losses, reduce the amount they store. In contrast, households that store maize with the intention of selling it later in the year appear unaffected by liquidity constraints. Instead, these households store less when they expect to lose more during storage. These results suggest that policies to provide liquidity will be more helpful in motivating storage among consumption‐oriented households. Households motivated to store for later sale will benefit from modern storage technologies that mitigate the operational costs associated with storage losses.

“…This technology provides grains protection for both short and long time storage against insect pests, pathogen, birds, molds, rodent, theft, and other domestic animals (Yusuf and He, 2013;Tefera et al, 2011;Gitonga et al, 2015). A metal silo is a cylindrical (Figure 22), square or rectangular prism structure, constructed from a high quality galvanized iron sheet and hermetically sealed with a top inlet and a smaller bottom lateral outlet (Bokusheva et al, 2012). The main advantage of metal silo is hermetically sealed.…”

“…In addition, metal silo improved food security, maintained grain quality, reduce women's workload, improved family health, and reduce usage of storage pesticides. Also, improve hygiene, and welfare and creates jobs for artisans/metalworkers (Bokusheva et al, 2012;Bravo, 2009) Guatemala, Nicaragua, and El Salvador, corresponds to 13 % of the region annual production of maize. This is equivalent to food for over 50,000 families and worth more than US$12 million (Bravo, 2009 Tefera et al (2011) and a research paper by Gitonga et al (2015).…”

Agriculture is the backbone of Tanzanian economy. It accounts for about one-third of the gross domestic product (GDP), provides 85 percent of all exports and saves as a livelihood to over 80 percent of the total population. Maize is the primary staple crop; it's grown in nearly all agro-ecological zones in the country. Tanzania is a major maize producer in Sub-Saharan Africa. In the last four decades, Tanzania has ranked among the top 25 maize producing countries in the world. In the 2013/14 growing seasons Tanzania produced over half billion metric tons of maize of these maize smallholder farmers produced around 85%. Despite the steady production of maize over the past three decades, post-harvest losses of maize remained significant, up to 30-40 % in some rural areas. Post-harvest handling, poor infrastructure, weather variability, biotic factors such as insects and pests, bacteria, pathogens, viruses, and fungi, often aggravate such losses. Mycotoxin producing fungi pose a major risk. Mycotoxins are toxic secondary metabolites of fungi that frequently contaminate the maize in the field and/or during storage. Mycotoxin contamination of maize poses a health risk to humans and animals if not properly managed. The most important mycotoxins in Tanzania are the aflatoxins, fumonisins and Ochratoxin. The objective of this paper was to review current literature on the production trends, consumption, post-harvest losses, and mycotoxins contamination of maize and to provide strategies to control and prevent postharvest losses and mycotoxins contamination in Tanzania.

“…During the storage of soybean in large quantities for a long time in warm weather, it is necessary to provide ventilation to prevent the development of mold and self-heating, even when the moisture content is low (Bokusheva et al, 2012). Without ventilation, the grain may turn rancid and discolour, which will reduce its quality.…”

The article investigates and substantiates the operating modes of container-modular equipment with active ventilation, such as specified (real) productivity, power consumption of the conveying process, as well as the use of a progressive method of controlling the humidity and temperature in soybean storage volume. The experimental equipment which adequately simulates the proposed technology for soybean storage with active ventilation for the calculated data verification was developed. The experiments confirmed that the proposed experimental equipment enables to adequately simulate the process of soybean storage with active ventilation and conduct experiments with the regulation of basic parameters such as productivity, power consumption, humidity, etc. using modern methods, devices and digital technologies. The experimental results were presented. Humidity and temperature were monitored during the experiments using the "Strazh Klimat" software. The experimental data were obtained, enabling to establish the dependence of the conveying height on the air flow velocity.
