Fertilization standards: 150 grams of urea and 0.25 kg of phosphate fertilizer are added to 50 kg of water until the end of June. In July, the P and K fertilizers were changed and 0.5 kg of phosphate fertilizer and 0.25 kg of potassium fertilizer were applied. Three small pits were dug at 50 cm from the trunk and covered with water.
