STEP - 1
Plough deeply, harrow and level the field before planting. Soil sterilization should be done by both physical and chemical means.
STEP - 2
Maintain space distance of 5-8 m. Spacing distance varies according to variety, soil fertility, and availability of irrigation facilities.
Increasing plant density increases productivity.
STEP - 3
The Guava plant propagates from seeds. Seedling trees produce fruits of variable size and quality although such trees are generally long-lived.
STEP - 4
In the early stage, young guava plants require 8 to 10 irrigations a year. Moderate watering is necessary for the summer season in dry areas and on light soils.
STEP - 5
Spraying the trees with 0.45 kg zinc sulfate and 0.34 kg slaked lime dissolved in (16 gallons) of water cures Zn deficiency. The number of sprays depends on the severity and extent of the deficiency.
Pre-flowering sprays with 0.4% Boric Acid and 0.3% Zinc Sulphate increase the yield and fruit size.
Also, you can spray copper sulfate at 0.2 to 0.4% to increase the growth and yield of guava.
