Planting distance should be three to four meters apart. Can be harvested after two to three years with an expected yield of 3.7 ton per hectare.
Planting Time. Use 250-300 gms. Complete fert. (14-14-14) or (12-24-12). Apply 3 inches below the roots and 5 inches to side of seeding at planting. Eight cm below roots and 10 cm to the side.
Young trees (1-3 years). Use 300-500 g of complete fert. (14-14-14) or (12-24-12) plus 200-300 g urea (45-0-0). Mix and apply in two equal doses by digging along periphery of the tree. First application – start of the rainy season. Second application – end rainy season.
Fruit Bearing Trees. Use 1.5-3.0 kg complete fertilizer plus 200-300 g Muriate of potash (0-0-60). Apply as above.
