Abstract

Deficit irrigation is a new innovative water-saving approach that decreases irrigation volumes while increasing water productivity in areas with limited water resources. The two-year research project was carried out to evaluate the impact of deficit irrigation levels on tomato fruit yield and water productivity in the Adola district. The experiment was designed utilizing a randomized complete block design with three replications. The treatments included three levels of irrigation deficit (50% ETc, 75% ETc, and 100% ETc). The statistical study showed significant difference in tomato fruit yield and water productivity when different deficit irrigation levels were applied at (p<0.05). According to the two-year data analysis, increasing deficit irrigation levels to 50% ETc of the soil before the next irrigation decreases marketable fruit yield by 15.20 and 8.7%, respectively, when compared to the highest marketable fruit yield recorded at 100 and 75% ETc. Moreover, the study found that as moisture stress increased from crop water need (100% ETc) to irrigation deficiency level of 50% ETc, water use efficiency increased. At 50% ETc, the greatest water use efficiency (20.42 kg/m³) was obtained. In general, the two-year complete analysis result of this study directed that applying 75% ETc level saves 25% more water available to irrigate more area without having a significant effect on tomatoes fruit yield with higher values of water usage efficiency. The water saved through deficit irrigation can be used to irrigate supplementary lands with greater profitability, resulting in a more efficient and reasonable use of land and water resources. According to the partial budget analysis, the biggest net benefit was (901,065 ETB ha^-1) recorded from 100% ETc treatment, followed by (853,070 ETB ha^-1) from 75% ETc treatment. In conclusion, the current study shows that conventional furrow irrigation with 75% ETc is more economically feasible than the other treatments used in Adola District and similar agro-ecology.
