Irrigate copiously right after planting, again on the third day, and then once in 10 days or as needed. Per tree: FYM 50 kg and 1 kg each of N, P and K in two splits, in March and October. To increase yield, spray urea 1% + zinc sulphate 0.5% twice a year (March and October). For boron deficiency (small leaves, fruit cracking and hardening), spray 0.3% borax (3 g/l) at flowering and fruit set.
