Uttar Dinajpur Krishi Vigyan Kendra is vested with the responsibilities to bring forth agricultural vis-à-vis rural development in the rural blocks of Uttar Dinajpur District through its mandated activities on training of practicing farmers, rural youth and extension functionaries, front line demonstration and on farm testing/adoptive trials to enhance the total production of the district as well as self-employment generation. Uttar Dinajpur district is situated in between Darjeeling and South Dinajpur district of West Bengal in North South direction whereas; it is surrounded by Bihar and Bangladesh in West and East direction respectively.

Out of 3, 12,466 ha geographic area of the district 87.23% area is under cultivation. The district comprises of two sub-divisions, namely, Raiganj and Islampur. There are four blocks under Raiganj sub-division whereas Islampur sub-division consists of five blocks; among which the Uttar Dinajpur K.V.K. farm is situated in Chopra Block. The latitude and longitude of the farm is 260 21’18” N and 880 16’36” E respectively. Uttar Dinajpur district lies between 25o 11' N to 26o 49' N latitude 87o 49' E to 90o 00' E longitude.

Uttar Dinajpur district belongs to both of Terai and Old Alluvial zone. Islampur sub-division comes under Terai zone whereas, Raiganj sub-division falls under Old Alluvial zone. This district experiences as typical subtropical pre-humid climate with high annual rainfall (average 2087 mm year-1) mostly concentrated in between June to September. The heavy rains often cause flood in some areas. The relative humidity varies from 64.32% - 98.31%.

The soil of this area is alluvium and mostly sandy to sandy-loam in texture and porous. As a consequence of leaching of bases due to heavy rainfall in this region, soil reaction is moderately to strongly acidic (pH varies from 4.5 to 6.2). The organic matter content is medium to high. Available P and K status is low to medium. Phosphate fixation capacity is high. Ca and Mg and some of the important micronutrients are deficient. The productivity of the soil is generally low but there is tremendous scope for improving the same by soil amelioration with Dolomite available in Jayanti hills.The period from November to February is dry but cool. High ground water and prolonged winter are found to be favourable factors contributing to successful raisin of a good number of rabi crops. Rice, jute, Potato, Ginger, Pineapple etc. are major crops of this district. However, there is a trend to convert the agricultural lands into tea gardens.

Frequently Asked Questions

The SRI is an alternative to the traditional way of flooded rice cultivation and is showing promise in addressing the problems of water scarcity, high energy usage and environmental degradation. SRI involves few major components viz., using younger seedlings, square planting, irrigation by alternate wetting and drying, weeding though cono/rotary weeder, LCC based N management.

Organic farming is a system, which avoids or largely excludes the use of synthetic inputs (such as fertilizers, pesticides, hormones, feed additives etc.,) and to the maximum extent feasible relies upon crop rotations, crop residues, animal manures, off-farm organic waste, mineral grade rock additives and biological system of nutrient mobilization and plant protection.

Green leaf manuring refers to turning into the soil green leaves and tender green twigs collected from shrubs and trees grown on bund, wasteland and nearby forest areas. Glyricidia, Pongamia, Leucina are common green leaf manuring crops.

Compost is well decomposed organic wastes like plant residues, animal dung, urine earth from cattle sheds and waste fodder etc.

To feed the Colostrum for newborn calf within 30 minutes of birth. Quantity of colostrum feeding is 1/10th of calf body weight, up to maximum of 2-2.5 litre per day for three days.

For better production the comfort temperature for livestock is 65-75oF.

To manage leaf folder in Paddy release Trichogramma Chilonis @ 5 cc/ha (1,00,000 nos.) at weekly intervals, 3 times from 42 days onwards. Application of botanicals especially NSKE @ 5%.

  • Raise the mat nursery for plant establishment
  • Seed rate 7-8kg/ha for single seedling per hill
  • Transplant young seedlings aged 15 days having 2-3 leaves with seed attached to the root
  • Square planting of 22.5 x 22.5 cm (9 x 9 inch)
  • Use leaf colour chart for the determining the time for top dressing N fertilizer
  • Irrigation only to moist the soil in the early period of 10 days. Restoring irrigation to a maximum depth of 2.5cm after development of hairline cracks in the soil until panicle initiation
  • Moving the Rotary weeder / Conoweeder with forward and backward motion to bury the weeds and as well to aerate the soil at 7-10 days interval from 10-15 days after planting on either direction of the rows and column

  1. It helps in maintaining environment health by reducing the level of pollution
  2. It reduces human and animal health hazards by reducing the level of residues in the product
  3. It helps in keeping agricultural production at a higher level and makes it sustainable
  4. It reduces the cost of agricultural production and also improves the soil health
  5. It ensures optimum utilization of natural resources for short-term benefit and helps in conserving them for future generation
  6. It not only saves energy for both animal and machine, but also reduces risk of crop failure
  7. It improves the soil physical properties such as granulation, and good tilth, good aeration, easy root penetration and improves water-holding capacity
  8. It improves the soil's chemical properties such as supply and retention of soil nutrients, and promotes favorable chemical reactions

Green manuring can be defined as practice of ploughing or turning into the soil undecomposed green plant tissues for the purpose of improving physical structure as well as fertility of the soil. Sunhemp, Sesbania, Crotalaria, Pillipesara, Cowpea etc are good for green manuring.

Compost making is the process of decomposing organic wastes in a pit. Site for compost making is selected should be at a high level and water should not pond during monsoon season. Pit should be of 3' depth and 6' to 8' width. Length may be of any convenient size. The process is as follows :

  1. Make slurry of the cattle dung with water
  2. Prepare 6" layer of organic wastes-plant residues, sweepings from the cattle shed,waste fodder, dried plants stalks and leaves etc. and sprinkle water to just moisten it. (Over watering should be avoided)
  3. Cover with the layer with urine earth and cattle dung slurry
  4. Add 5 to 10 kg of super phosphate for every 10 tons of organic wastes
  5. Repeat the process of putting such layers till the pit is full
  6. Close the pit with urine earth, waste fodder and then heap the soil till it gets convex shape (about 1 to 1.5' above the ground) so that the rainwater rolls away
  7. After six months compost is ready to apply to the fields

The pit can be filled up if sufficient organic wastes are available. Otherwise a temporary partition can be made in the pit with bamboos or stalks and the pit can be filled up over time filling each partitioned area as and when the material is available for composting.
