EFFECT OF SPRAYING WITH DIFFERENT LEVELS OF SEAWEED EXTRACT AND POTASSIUM SULFATE ON THE GROWTH AND YIELD OF EGGPLANT

An experiment was conducted to study the response of three eggplant cultivars for the 2022 season to spraying with three levels of seaweed extract and three levels of potassium sulfate. The results showed that there were significant differences in the treatment of spraying seaweed extract B2 at a concentration of 2 ml / liter in plant height. cm and weight of the fruit(g) and the proportion of nitrogen N% and phosphorous P% in the leaves (9.943 - 192.077gm - 84.928cm - 0.342) respectively. The study also showed that there were significant differences in the treatment of spraying potassium sulfate C2 at a concentration of 2 ml / liter in plant height cm. The fruit weight ( g) and the percentage of nitrogen N% and phosphorus P% in the leaves (0.307 - 9.266 - 184.978gm - 80.504cm), respectively .The results also showed that the interaction between seaweed extract and potassium sulfate had a significant effect on most of the studied traits. The weight of the fruit (g)and the percentage of nitrogen% N and phosphorus % in the leaves (10.484 - 194.557gm - 90.623cm - 0.360), respectively.
