This review evaluates the effects of different irrigation methods on coffee yield and water productivity (WP) in Ethiopia's Jimma and Wollega zones, aligning with global trends. Drip irrigation consistently results in the highest coffee yields, producing 3870 kg ha-1 in Jimma at Melko, a 48% increase over surface irrigation and a 142% increase over rainfed conditions. In East Wollega at Wayu, drip irrigation yields 2035 kg ha-1, 45% higher than surface irrigation and 213% higher than rainfed farming. Surface irrigation, although less efficient than drip, still offers significant improvements over rainfed methods, with cheery yields of 3000 kg ha-1 in Jimma at Melko, 2330 kg ha-1 in Jimma at Gera district, and 1402 kg ha-1 in West Wollega at Haru district, demonstrating increases of 63%, 48%, and 115%, respectively, over rainfed conditions. Rainfed agriculture consistently delivers the lowest yields, highlighting its vulnerability to water scarcity, with only 1600 kg ha-1 in Jimma at Melko and 650 kg ha-1 in West Wollega at Haru district. The review emphasizes the need for better irrigation and agronomic practices to boost productivity and climate resilience in Ethiopian coffee production. Drip irrigation also achieves the highest WP, with 0.38 kg m-³ in Jimma (Melko) and 0.17 kg m-³ in East Wollega (Wayu), surpassing the lower WP values of surface irrigation and rainfed methods. The findings advocate for more efficient irrigation techniques to enhance coffee yield and WP, in line with global practices.

The concentration of nitrogen fertilizer is matched with the nutrient requirements in different growth stages of plants, which coordinates their vegetative and reproductive growth. In this study, the influences of nitrogen concentration before and after initiation of flower bud differentiation (first and second stage, respectively) on pepper seedling quality were studied. The chlorophyll a content, sucrose synthase activity, and sucrose phosphate synthase activity of pepper seedlings grown under moderate nitrogen (15 mmol L−1) in the first stage combined with high nitrogen (25.61 mmol L−1) in the second stage were 15.7%, 39.3%, and 34.6% higher than those of the same nitrogen concentration (15 mmol L−1) in the first and second stages treatment, respectively. The regression model also showed that the values of flower bud diameter, shoot fresh weight, root fresh weight, and glutamine synthetase activity of pepper were high under the condition of moderate nitrogen in the first stage and higher nitrogen in the second stage. In addition, the results of comprehensive evaluation showed that moderate nitrogen (15 mmol L−1) in the first stage and high nitrogen (25.61 mmol L−1) in the second stage treatment ranked first, which improved carbon and nitrogen metabolism, increased biomass accumulation, and promoted the flower bud differentiation and flowering of pepper seedlings.
