| Abstract | ||
| During the 2023 - 2024 spring season, this experiment was conducted in the Government Thamar Special Farm. There are no appreciable differences between the various irrigation levels in the tomato fruit length; the highest value in the length recipe was obtained at the 100% ETc, with an average length of 21.949 mm, and the lowest value was obtained at the 60% ETc, with an average length of 19.836 mm. Consequently. The tomato crop's diameter measured at the 100% irrigation yielded the maximum average fruit diameter of 37.926 mm, while the lowest average fruit diameter measured at the 60% under-irrigation was 30.893 mm. At a significance threshold of P < 0.05, there were significant variations between the amounts of deficit irrigation for the tomato fruit diameter (4.1610). In addition, the 100% ETc the highest value for the efficiency of fertilizer use to produce the tomato crop, with an average of 35.248 kg of tomatoes per kilogram of fertilizer; the 60% deficit ETc the lowest value, with an average of 5.193 kg of tomatoes per kilogram of fertilizer. | ||
