- Abstract
A study was conducted in a private farm the rural area of province o Najaf during the 2017 and 2018 growing seasons to study the effect of three factors including two plant varieties, spraying with boric acid at three levels and soil application with potassium sulfate at three levels on seed yield parameters in table beet. The experiment was factorial split-split plots based on Randomized Complete Block Design (R.C.B.D) with thee replicates. The main factor was two plant varieties (Local and Imported) treated with or boric acid (17% B) at 0 (B0), 5 (B1) or 10 (B2) g/L and potassium sulfate (50% K2O) at 0 (K0), 100 (K1) or 150 (K2) kg/hectare, results showed that plant variety and spraying with boric acid had significant effect on number of seeds.fruit-1, total yield and fruit yield per unit area for both seasons and weight of 100 fruit.plant-1 for the 2nd season. However, fertilization with potassium sulfate significantly affected speed of seed germination and was the most effective in reducing germination period and rate, beside its effect on some studied parameters. Generally, best results were obtained from the total interaction of the three factors especially at highest concentration levels. Among all the treatments, the K2-B2 treatment resulted in the highest values in weight of 100 fruits, total yield.plant-1 and number of seed.fruit-1 for both varieties and highest pollen viability for local variety. The K1-B2 on the other hand had the best results in terms of fruit yield per unit area. In this study, we clarified the synergistic effect of boron when combined with potassium in improving plant growth in general and increasing quantitative and qualitative parameters of seed yield in table beet.
