Title: Design, development and testing of Water Harvesting in Rows Planter (Wahip) for marginal rainfed areas Authors: Yousif, Lotfie A.; Abdelhadi, A.W.; Babiker, Imad A. Ali; Babiker, Ebtehag H. Abstract: Seeding sorghum in the bottom of the ridge has been recommended in areas of low rainfall Eastern Sudan to mitigate water stress. One major constraint that rendered its adoption was the lack of a suitable machine. Providing a planter to achieve such operation can improve sorghum productivity. The objectives of this research were to design, develop and evaluate a planter that can make ridges while seeding sorghum in the bottom. Water harvesting in-row planter (WaHIP) was design and developed for this purpose. It is composed of four-unit-tractor mounted planter combined with a ridger toolbar. The external fluted wheel seed metering type was used and equipped with devices to regulate seed rate...
