दार्जिलिंग हिमालय क्षेत्र में कृष्‍णा फलों का विश्लेषण Passion fruit (कृष्‍णा फल), a high value foreign exchange earning fruit crop rich in appreciable quantities of vitamin A, B, C with medicinal value, is mostly grown at an altitude of 800-1500 m above mean sea level. The cultivation of passion fruit is mostly restricted to few of the North Eastern states and hilly regions of South India. It has a very good scope of commercial cultivation in the Darjeeling Himalayan Regions of West Bengal particularly Kalimpong and Kurseong subdivisions. This will help the small farmers to improve their economic condition that ultimately leads to overall prosperity of this region.  Darjeeling Krishi Vigyan Kendra will provide the necessary training in technical aspects of passion fruit cultivation by conducting trials at their experimental fields as well as adopted villages. Passion fruit, a native of Brazil is a high value nutritious foreign exchange earning fruit crop having high medicinal importance. Of about 500 species of Passiflora in the family Passifloraceae, only one species i.e. Passiflora edulis Sims, has the exclusive designation of passion fruit, preferably seen growing at an altitude of 800-1500 m above sea level. Within this species, there are two distinct forms, the standard yellow (Passiflora edulis f. Flavicarpa Deg.) and the purple (Passiflora edulis f. edulis). It is...

In Darjeeling region of West Bengal and Sikkim, cultivation of fruit crops mainly Darjeeling Mandarin is main source of livelihood for the farmers. In India, every year a huge loss to citrus production occurs due to damage caused by insect pests, diseases and off course physiological disorders. All these factors together cause a great damage to citrus crops; and growers as well as consumers are disadvantaged with it.   A. Disease Pests and their Management: The diseases are caused by fungi, bacteria, virus, virus like pathogens, etc. They cause severe damage to the mandarin orange cultivation. The major diseases affecting citrus crops in Darjeeling and Sikkim regions are as follows: 1. Gummosis disease (Causal organism: Phytophthora palmivora, P. citrophthora, P. nicotianae var. parasitica): The characteristic symptom of the disease is exudation of gum from bark of the tree trunk.

दार्जिलिंग और सिक्किम के उत्तर पूर्वी पहाड़ी क्षेत्र में मेंडारि‍न ऑरेंज के 7 प्रमुख कीट तथा उनका प्रबंधन Major insect pests problematic to mandarin orange in North Eastern Hill regions of Darjeeling and Sikkim are leaf miner, citrus psylla, citrus fruit sucking moth, citrus stem borer etc. These major insects and their management are as following- 1. Citrus leaf miner (Phyllocnistis citrella): It is a common pest of citrus crops in India. The adult of this pest is a minute silvery white or greyish moth. Usually leaf miner is more active during their growth period i.e., in spring and rainy seasons. Tender leaves are attacked and leaf miner larvae feed on the epidermis, producing silver coloured serpentine mines, generally on the lower surface. Often the tiny caterpillars/grubs are found in them. Larvae also attack the tender branches where they mine under the epidermis. Both young and old trees are affected but the damage to young plants is more serious. A heavy attack may lead severe defoliation. The infested trees are devitalized and look sickly. Leaves which are mined also serve as loci of infection for citrus canker disease. Management: Chipping and destruction of mined leaves in the primary stage reduces insect infestation. Timely sprays of Dimethoate @ 2ml/L of water or Profenofos @ 2-3ml/L of water or Thiamethoxam...
