This study addresses various indigenous technology and knowledge-based food processing and storage methods used by rural women farming in Tanzania, focusing on the ways these can be improved for higher incomes. Primary data collected in June from small-scale women farming in Dodoma, Iringa, and Mbeya were analyzed with secondary data in order to meet the study objectives. The storage infrastructure is characterized by traditional methods, and sacks are the most widely used storage vessel. Farmers store the food crops for food security and to sell at a higher price later. The regression results revealed that poor storage facilities discourage increased farm production; therefore, efforts to achieve higher farm production should be accompanied by the improvement of indigenous farmers' storage facilities. Farmers themselves prefer hermetically sealed storage facilities such as drums and hermetic bags.

This paper aims to review the current status of wheat production, farming systems, production constraints and wheat demand-supply chain analysis; the role of international and national breeding programs and their approaches in wheat genetic improvement including targeting mega environments, shuttle breeding, doubled haploids, marker-assisted selection and key location phenotyping; and future prospects and opportunities of wheat production in Sub Saharan Africa SSA. Though traditionally wheat was not the leading staple crop in SSA, it is becoming an important food crop because of rapid population growth associated with increased urbanization and change in food preference for easy and fast food such as bread, biscuits, pasta, noodles and porridge. In , total wheat consumption in SSA reached 25 million tons with import accounting for Furthermore, increased cost of production, growing populations, increased rural-urban migration, low public and private investments, weak extension systems and policies, and low adoption rates of new technologies remain to be major challenges for wheat production in SSA. Wheat breeding in SSA is dominantly carried out by National Agricultural Research Systems, in partnership with the international research centers [International center for improvement of maize and wheat CIMMYT and International center for agricultural research in the dry areas ICARDA ], to develop high yielding and widely adapted wheat genotypes with increased water-use efficiency, heat tolerance and resistance to major diseases and pests. This paper will help to promote available wheat technologies in SSA by creating awareness to wheat scientists, extension agents and policymakers.

Wheat is fundamental to human civilization and has played an outstanding role in feeding a hungry world and improving global food security. Unprecedented productivity growth from the Green Revolution GR since the s dramatically transformed world wheat production, benefitting both producers and consumers through low production costs and low food prices. One of the key challenges today is to replace these varieties with new ones for better sustainability. Also productivity increase is now slow or static. Achieving the productivity gains needed to ensure food security will therefore require more than a repeat performance of the GR of the past. Future demand will need to be achieved through sustainable intensification that combines better crop resistance to diseases and pests, adaptation to warmer climates, and reduced use of water, fertilizer, labor and fuel.

Grain storage techniques: evolution and trends in developing countries

A small-scale maize harvester was designed and fabricated for developing countries and is composed of a harvester header, a chain conveyor, a drive power unit and a five-wheel tricycle. Fabrication of components was made and assembling of the devices on the tricycle was done. Three rotational speeds of the engine, , and rpm were used, while the forward velocity of the harvester was kept at an average of 0. The highest machine capacity was obtained at 0. However, it was observed that the machine noise level decreased with increase in engine speed.

Он узнал также и о том, что его заместитель просиживает на службе до глубокой ночи и может не выдержать такого напряжения. Несмотря на разногласия со Стратмором по многим вопросам, Фонтейн всегда очень высоко его ценил. Стратмор был блестящим специалистом, возможно, лучшим в агентстве. И в то же время после провала с Попрыгунчиком Стратмор испытывал колоссальный стресс. Это беспокоило Фонтейна: к коммандеру сходится множество нитей в агентстве, а директору нужно оберегать свое ведомство.
