CITRUS REJUVENATION IN NE REGION OF INDIA
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 2
Abstract
In the world, citrus is dominated by sweet orange with a 64% contribution followed by mandarins with 20%, limes and lemons 10% and rest of the 6% contributed by grapefruit and other citrus fruits. In India, the area under citrus is 1.07 million ha with a production of 10.48 million tonnes and average productivity of 9.78 tonnes/ha. The traditional mandarin growing areas of North-eastern hill states experience humid subtropical climate with high rainfall in monsoon (summer) and low temperature during winter months. Other citrus groups s can be grown in the foot hills and valley of North –eastern states include sweet oranges, lemon, lime, pummel etc. Rootstocks used for budding of mandarin oranges are C. volckamariana, Tanyum (Citrus medica), Citrange, Trifoliate Orange, Kamla Australia, Kharna Khatta, C. latipes and C. jambhiri. Heavy and long spells of rainfall, Soil erosion, Lack of desirable planting materials, Lack of application of amendments in acidic soils, Nutrient deficiencies, Rainfed cultivation, Lack of proper orchard management, No control of insect pests and diseases, Lack of marketing facilities, Problems of processing and Non-availability of trained manpower and extension support are major factor for citrus decline in the region. Strategies like proper Selection of site, Suitable method of planting, Supply of disease free elite planting material, Soil and nutrient management, Irrigation management, Proper orchard management, Management of insect-pests and diseases, Post -harvest management, processing and marketing and Extension services can be adopted for rejuvenation of old orchards. A suitable road map covering integrated approaches can be formulated for management of decline orchards.
