Citrus Growing Areas & Varieties in Pakistan
Propagation:
All the improved varieties are propagated by means of
budding on rough lemons or sour orange. Rootstocks are
generally grown through seed, T budding/T grafting are
the usual method of citrus cultivars propagation. Budding
may be done during spring (Feb-March) and autumn (August-October)
when bark slip freely from both scion and stock. Bud should
be selected from mature wood of productive and healthy
trees. In sweet lime propagation through cutting is a
common method.
Soil and Climate:
Citrus trees can be grown on a wide range of soils, including
deep sandy loam, loam and clay loam. However, they do
not grow well in very heavy, clayey, sandy, and alkaline
or water logged soils. Citrus fruits trees are grown in
tropical and sub-tropical climate. Temperature is the
main factor affecting, time of blooming, maturity, producing
and fruit quality of citrus.
Pruning:
At the time of transplanting the top portion should be
balanced with the roots by removing some of the leaves,
if necessary. Annual pruning is done to remove dried,
diseased and those branches overcrowding the top of the
tree. For a young citrus tree to have good frame work,
no branches should be allowed on the main stem and two
to four evenly spaced main limbs should be selected to
provide balanced frame work. In Pakistan however, no systematic
pruning is followed except for removal of dried, diseased
and unwanted twigs.
Water Management:
The preferred method of irrigation is a basin round each
tree the size of. There should be channels connecting
basins so that irrigation of fruits trees can be independent
of the intercropped area between the tree lines which
have different water requirements. Growth sensitive periods
to water shortage are flowering time (Feb/Mar), fruit
setting (Apr/May).
Fertilizers and Manures :
- Apply FYMs at the rate of 40 to 80 kg per tree
during the winter season in Dec/Jan before flowering
- Apply 3-4 kg SSP and 1.5 to 2 kg of Urea 15-20 days
(Jan/Feb) febore flowering
- Supply a further amount of Urea of 1.5 kg per tree after fruit setting (Mar/Apr)
- If necessary 1.5 kg of Potassium Sulphate may be applied at the time of applying FYM
- Watering is essential after each application of fertilizer
