Response of Some Sunflower (Helianthus annuusL) Hybrid Cultivars as Influenced by Argel (Solenostemmaargel, Del. Hayne) and Nitrogen Under Irrigation in Sudan

A field experiment was conducted during 2017/2018 to assess the effects of Argel (Solenostemmaargel, Del. Hayne) and Nitrogen fertilizer on the performance of two Sunflower Hybrid cultivars, with the objectives to exploit an easy, economic, and accessible organic fertilizer, the Argel in the phase of the continuous increasing prices of chemical fertilizers.. This experiment was laid out on spilt-split-plot experiment in Randomized Complete Block Design (RCBD) with four replications. Observations were taken on some agronomic traits (Plant height (m), Leaf area (LA), leaf Number (NL), Leaf Area Index (LAI) and Mean Seed Weight). The results revealed that the application of Argel and Nitrogen fertilizer have significantly increased the leaf Area (F= 7.22, P < 0.001), Plant Height (F=2.68, P < 0.2001), Leaf Number (F= 3.90, P < 0.0024), Leaf Area Index (F= 3.83, P < 0.0026) and Mean Seed Weight of both Serena and Opera cultivars respectively compared to the control. However, the different treatments of Argel and Nitrogen reflected variable degree of increase for the studied parameters. The study concludes that Argel is very promising, therefore a further study with different levels of Argel including other plant parameters is recommended.

The impacts of Upper Blue Nile Dams construction on agricultural water availability of Sudan

Abstract The objective of this research is assessing water resource availability in the Blue Nile River for different development scenarios using Mike Hydro modeling. The long term Blue Nile total irrigation water demand will be more than 46.67 × 109m3, which is nearly similar to the naturalized flow (around 48 × 109m3). In the phase II irrigation, water shortfalls increase to 0.38 × 109m3/year. There is up to 2.172 × 109m3/year irrigation water deficit at the full development level in Ethiopia. Due to flow regulation, there are no shortfalls in irrigation in Sudan in either the medium or the long-term. Dams located in Ethiopia give more advantage to the Sudanese schemes than that of Ethiopian regarding irrigation development.

Gezira Scheme between state and market: some remarks on the privatization of irrigation in Sudan

This paper is a study of so-called privatization of the great Sudanese Gezira Scheme, under the structural and budgetary problems of the country. Nothwithstanding the official declaration, in reality privatization affected the project just in nominal way. Indeed, two factors play against it: the resistance of the State, which wants to hold the management of the national strategic resources, and the resistance of the territory itself which — as autopoietic system — reacts against any attempt to change its own structure. The islamic renewal(tajdid) can be considered as a way to solve the dilemma between development and social consent, under these new conditions.

Irrigation in Sudan since Independence

Four million feddans in Sudan are irrigated. Half of the total was developed since 1955, and production in the previously irrigated areas has been intensified. Despite these achievements, the schemes are not operating well. Aid agencies, chiefly the World Bank, have lent more than $700 million to build, maintain, and rehabilitate them, but these programs promote high technologies and assign a passive role to farmers. A cooperative program between researchers and farmers might lead to a better form of irrigated
