About Lesson
Propagation
- Vegetative propagation
- Budding
- Shield or T budding in May-June or September
- Grafting: Whip and tongue grafting in January-February
- Top working:
- Stooling
- Cutting: Hardwood cutting treated with IBA 100ppm in October
- Micropropagation
Â
Planting
- Effective in late winter season.
- Requires less spacing than apple with optimum planting distance of 4-6 m.
- Pit size of 60-75 cm3 is required.
Â
Flowering habit
- The inflorescence contains 7-8 flowers and is indeterminate.
- Flower initiation occurs about 60 days past bloom.
- Flower bud is formed on the terminal of shoots or spurs 2 years older branches.
- However, hardy and comince on quince rootstock tend to flower lightly following a heavy crop year.
Â
Training and pruning
- Can be trained modified leader system, free standing and etc.
- Pear trees tend to become less productive at an age of about 20 yrs.
- Such orchards can be restored by rejuvenation
- It can be achieved by heading back the 3-4 main scaffolds to about 15cm during Dec-Jan
- The rest scaffolds should be completely removed
- Paint the cut ends with Bordeaux paste
- Many sprouts shall emerge on these stubs in March
- In May, retain only 1-2 outgoing shoots on each stub with a total of 6-8 shoots per tree
- Rejuvenated trees start fruiting in third year and bear commercial crop in the fifth year
Â
Manure and fertilizer
- Compost- 50kg/plant, DAP-434.78g, Urea- 699.43g and MoP-66.67g per bearing fruit
- FYM, Phosphorus, MOP and ½ N during December
- Remaining half should be applied before flowering and in April after fruit set.
Â
Irrigation
- Irrigation is required during fruit growing season at an interval of 5-7 days
- No irrigation should be given in January
- For color composition, dessert and keeping quality of fruits, neither too little nor too much water is needed
- Under relatively dry conditions fruits develop higher acidity and better flavor
- After fruit harvesting, tree should be irrigated at an interval of 20 days
Â
Fruit thinning
- Fruit thinning is practiced in cultivars having heavy fruit set like Bartlett, Beurre hardy, Anjou.
- Generally, one fruit per 30-40 leaves should be retained.
Â
Harvesting and yield
- Fruit maturity can be judged by evaluating the color change.
- When the green fruits turn brownish yellow and stalk become easy to separate from spur, then harvest fruits for local market.
- Fruits should be harvested when fruits have not yet developed full colour.
- Fruits should be sweet and crispy when harvested.
- Oriental pear: 200 kg/tree/year
- European pear: 50-70 kg/tree/year
- Hybrid pear: 100 kg/tree/year.
