Abstract
The research results indicate the importance of expanding the cultivation of high-yield varieties of the summer yellow maize crop, in order to bridge the gap between consumption and local production thereof, which contributes to increasing the state's trade balance deficit as a result of the import from abroad. The results also indicated a proposal for a varietal map represented in the cultivation of high-yield varieties, single hybrid 168, yellowish-golden, single hybrid 3062 in the Upper Egypt sector, and varieties of single hybrid 176, single hybrid 162, single hybrid 168, single hybrid 166, and triple hybrid 360 in the outside the valley, while maintaining the cultivation of the current varieties in the Lower Egypt and Middle Egypt sectors. The application of this varietal map results in an increase in ardab yield by an estimated increase of 6.6% and 1.5% in the sectors of Upper Egypt and outside the Valley, respectively, in addition to increasing the income of yellow maize producers and raising the percentage of self-sufficiency therefrom. The study recommends the necessity of applying the proposed varietal map, with the provision of improved seeds from them at appropriate prices in their production areas, in addition to providing extension services and technological methods that lead to an increase in the feddan yield of yellow maize.
