16 Nov Production technology of low chill pear (Pyrus spp.) under subtropical condition of India
भारत के उपोष्णकटिबंधीय क्षेत्रों मे कम सर्द नाशपाती के उत्पादन की प्रौद्योगिकी Pear, an important fruits of the temperate region, belongs to the family Rosaceae. In India pear cultivation is mainly confined to the temperate Himalayan mountains at 1,700-2,400 m above mean sea level which have ideal conditions to grow a large number of European (Pyrus communisL.) and oriental [P. pyrifolia (Burm.) Nakai ] pears. Selection and development of low chill pear cultivars had made it possible to grow pear in subtropical regions of India also. Now pear is cultivated as a commercial crop under the tarai region of Uttar Pradesh, Punjab and Uttrakhand because these area has a typical subtropical climate with cold winters, necessary for meeting chilling requirement and mild temperature, suitable for flowering and better fruit set. it is highly nutritious in nature, having 0.7 g protein, 4.0 g fiber, 13.0 mg calcium, 16.0 mg phosphorus, 0.3 mg iron, 20.0 IU vitamin A, 0.02 mg thiamine, 0.04 mg riboflavin, 0.1 mg nicotinic acid and 4.0 mg ascorbic acid per 100 g edible fruit. Soil and climatic requirement for low chill pear : Although under hilly area, pear require about 1200 hours of chilling temperature below 70C for satisfactory flowering and fruiting but a large number of low chill pear cultivars are grown under...
