INTRODUCTION

- Psidium guajava is the scientific name for guava, which belongs to the Myrtle family.
- Guava trees can reach a height of 10 meters (33 feet) and live for 40 years.
- Guava is a tropical fruit that is mostly grown in the tropics.
- The guava tree is easily identified by its smooth, thin brown bark that peels off to reveal a greenish layer beneath.
REQUIREMENTS
• Soil- Sandy loam.
• Cultivation- Well-drained soils are best for guava cultivation.
• pH- 4.5-8.2
• Temperature- 20 to 25°C, If there is a high temperature at the time of fruit development, it can cause fruit drop.
• Susceptibility- They are susceptible to pests.
• Rainfall- 500-1000 mm.
IRRIGATION
- To allow the root system to develop and become established, water newly planted guava trees every two days for the first week after planting, then once a week for the next few months.
- Grass and weeds should be kept to a minimum in a 0.6 to 1.5 m (2.0-5.0 ft) radius around the trunk.
- A layer of organic mulch, such as bark or wood chips, can be applied around the base of guava trees to help them thrive.
- Allow a 20 to 30 cm (8-10 in) gap between the trunk and the mulch layer; do not mound the mulch around the trunk.
- The type and amount of fertilizer applied to young trees vary depending on the area and soil type.
- Pruning To foster the development of laterals, young trees should be trimmed.
- This is accomplished by chopping existing laterals back to 30 to 60 cm (1 to 2 ft).
- Three to four lateral branches should be let to grow 60 to 90 cm (24-36 in) before the tips are clipped to facilitate further branching during the first year of growth.
- When new shoots grow as a result of this process reach 60 to 90 cm, they should also be pointed (24-36 in).
- Established trees should be pruned to keep their height moderate and to open up the canopy.
CULTIVATION
- Guavas for processing can be produced from seed, with roughly 70% of seedlings retaining the parent tree's genetic features.
- Sowing seeds Before being transplanted in the field or garden, guava seeds are normally started in nursery beds or pots.
- Planting should only be done with seeds from healthy, strong trees that have the necessary features.
- Seeds should be planted in sandy soil flats and covered to a depth of 6 mm (0.25 in).
- Within 15 to 20 days of seeding, most seeds germinate.
- Seedlings should be transplanted into separate pots when they reach a height of 3.8 cm (1.5 in).
- Seedlings are being transplanted.
- To avoid shade, guava trees should be planted in full sun and spaced 4.5–7.5 m (15–25 ft) apart from other trees and buildings.
- A hole somewhat larger than the existing root ball should be dug, and a layer of compost or rotten manure should be added to the bottom of the planting hole.
- By placing the seedling upright in the planting hole and backfilling the dirt surrounding the plant, the tree should be planted at the same depth as it was in the nursery.
