The leaves are medium in size and the tree has a dense foliage. The fruit is large, with rough surface and ribs on shoulders, having creamy white, smooth juicy flesh with excellent taste, with 10-12 percent TSS. In full grown trees, the fruit yield may vary from 125 to 150 kg per tree.

SOIL AND CLIMATE
Guava is successfully grown under tropical and sub-tropical climatic conditions owing to its wider adaptability. Soils for guava should be deep, well-drained, friable, sandy loam to clay loam  and with pH ranging from 6.5 to 7.5,

 

PLANTING MATERIAL
Patch budded plants are used as planting material.

 

 

 

SEASON OF PLANTING
Guava may be planted in February-March or August-September with earthballs or bare rooted.

 

SPACING
A spacing 5 – 6m in either way is generally followed.

 

PLANTING
Plant the layers with the ball of earth in the centre of pit of 45 cm x 45 cm x 45 cm size filled with FYM 10 Kg neem cake 1 Kg and top soil

 

IRRIGATION
Irrigate copiously immediately after planting, again on third day and afterwards once in 10 days or as and when necessary.

Farmyard manure should be applied in May. Half of the inorganic fertilizers should be applied in May-June and the remaining half in September-October.

 

INTERCROPPING
Legumes and short duration vegetable crops may be raised during pre-bearing stage.

Crop Regulation

 

Guava gives two crops a year. Winter season crop is superior in quality than rainy season crop, which may get infested with fruit flies. In order to get only winter season crop, the following methods may be adopted.

 

Spray urea 10 per cent or naphthalene acetic acid (NAA) @ of 600 mg/litre during May, when maximum flowers have opened. Each tree needs about 10-12 litres of solution i.e. about 1000 litres per acre. For making this concentration of NAA, dissolve 600g of NAA in 1500-2000 ml alcohol, then make the volume of 1000 litres.

 

Pruning of terminal portions of the shoots upto 20 or 30 cm between 20th to 30th April avoids completely the rainy season crop.

Apply fertilizers during June to encourage growth in July-August for getting maximum flowering during August-September for winter season crop.

 

Withhold irrigation during April-May.

 

PLANT PROTECTION

Pests

Fruit fly

Avoid taking rainy season crop only in orchards with history of severe fruit fly infestations.

 

Harvest the ripening fruits and do not allow the ripe fruits on the tree.

 

Regular removal of fallen fruits from the ground and bury the infested fruits atleast at 60 cm depth.

 

Shallow ploughing with cultivator immediately after harvest is effective in exposing and killing the pupating larvae/pupae which are mostly present at 4-6 cm depth.

 

In orchards only with history of severe fruit fly infestations, Spray 1250 ml Sumicidin 20 EC

 

Mealy bug 
The mealy bugs can be controlled by Drench spraying of insecticides like 1875 ml Durmet/Dursban/Coroban 20 EC (chlorpyriphos) in 500 litres of water

 

DISEASES


Wilt:

Plant guava in a well drained field. Avoid too heavy soils.

 

Fruit Rot, Anthracnose or Die Back:

After pruning, spray the trees with 300 g of Blitox or 300 g Captan in 100 litres of water. Repeat the spray after the fruit set and continue spraying at 10 to 15 days interval till maturity.
