Extensive applied experiments at this station since 2000 have included six main areas, namely: experiments with sorghum, sesame, cotton and sunflower varieties, fertilization experiments in terms of types and sources of fertilizers as well as their addition rates and addition dates, plant density experiments in terms of seed rate, experiments in row and planting distances, and observations about promising crops.
| Experiment | Target |
|---|---|
| Comparison of sorghum varieties | This experiment compared three varieties of sorghum crop, namely Wad Ahmed, Tabat and Liberty, to determine high productivity varieties suitable for the rainfed conditions and zero-tillage system in Gedaref. |
| Comparison of sesame varieties | The experiment compared three varieties of sesame crop, namely Khider, Promo and Hilan, to find high productivity varieties suitable for rainfed, zero-tillage agriculture. |
| Comparison of cotton varieties | The experiment compared different varieties of cotton crop nominated by the Sudanese Agricultural Research Authority, namely Barack 67 B, Akala 93 H, Bar 57/12, BB 55 and L 82, to determine high productivity varieties suitable for rainfed, zero-tillage agriculture. |
| Comparison of maize varieties | The experiment compared different varieties of maize crop, namely Hicorn 53, Hicorn 75, PAN 6480, Hudiaba-1, among others, to determine high productivity varieties suitable for rainfed, zero-tillage agriculture. |
| Experiment | Target |
|---|---|
| Effect of NPK and urea fertilizer on sorghum crop (Wad Ahmed) | The experiment was conducted to find the optimal fertilization program in terms of fertilizer type and appropriate doses. |
| Nitrogen fertilizer fragmentation | The experiment compared the use of ammonium nitrate fertilizer at 1.5 N/acre, applied once upon planting, with the farmers' method (1 N at planting + 0.5 N, 4 to 6 weeks after planting). |
| Addition of NPK compound fertilizer | The experiment was conducted to compare the addition of NPK fertilizer (17:17:17) with the fertilizer treatment used in the farmers’ program. |
| Experiment | Target |
|---|---|
| Row spacing in sesame crop (Promo) | The experiment was conducted to determine the most appropriate distance between rows of sesame plants in terms of productivity for rainfed, zero-tillage agriculture. |
| Experiment | Target |
|---|---|
| Weed control in fields of sorghum (Wad Ahmed) and sesame (Promo) | The experiment aimed to reduce herbicide resistance in weeds and pests by finding alternatives to commercial products, as well as reducing the cost of herbicide application. |
| Experiment | Target |
|---|---|
| Effects of row spacing on the growth and productivity of maize | This study compared different sorghum planting densities to determine the optimal density in terms of productivity under the rainfed, zero-tillage agricultural conditions. |
| Experiment | Target |
|---|---|
| Measuring soil moisture in farm fields | The experiment was conducted to monitor seasonal soil moisture changes and their relative connection to achieved productivity. |
