Agronomical Research



Based on Climate, Soil and Physiography the South Asia Project Department, World Bank (1997) reported six agroclimatic Zones of West Bengal. Among them New Alluvium Zone is the biggest Zone with highest cropping intensity and crop diversity covering the western parts of Malda and Dakshin Dinajpur, Southern parts of Uttar Dinajpur, eastern part of Murshidabad, Hoogly, Burdwan and Howrah, entire Nadia and northern part of North and South 24 Parganas

Climate of this zone was tropical moist sub-humid with rainfall 1427.4 mm, air temperature maximum 35.0 C and minimum 15.6 (annual normal)

Soils of this zone are derived from recent alluvial deposits brought down by the river Ganga, and its tributaries hence called inceptisol. Soils are deep , well drained, texturally fine loamy, neutral in reaction, with high base saturation and CEC and medium to medium low NPK

Rice is the main crop cultivated in this zone over different land terrains and seasons. Aus, Sesame and Moong in pre-kharif or early wet season; jute and aman rice in kharif or wet season and wheat, different oilseeds & pulses, potato etc. are mainly grown in this zone. Boro or summer rice and sugarcane are also important crops commonly cultivated by the farmers

Zonal adaptive Research Station (New Alluvium Zone) (ZARS) started functioning in the month of October 1978 with its headquarter at Krishnagar (883' N 2324' E and 15 AMSL) to look after the agricultural problems and to adopt new agro techniques in this zone.

ZARS with its research personnel of different disciplines is engaged with farmers' advisory service and adaptability test of better techniques. This research station maintains close liaison among farmers, agricultural research institutes of states, agricultural universities and the extension wing of the directorate.

Farmers' Consultancy

Adaptive Trial

Farmers of this zone are approaching directly or through extension experts for immediate solution of their field problems like insect pest and disease occurrences, selection of situation specific remunerative cropping sequences or suitable crop or appropriate variety of a crop and agronomic practice viz. fertiliser recommendation, irrigation scheduling etc.

Cropping System Evaluation

Economically Jute - Potato - Rice, Rice - Potato - Rice and Rice - Potato - Sesame are suitable for large and medium farmers with higher production and net return in the medium irrigated land situation. These cropping systems recorded higher energy output and energy productivity but had lower energy use efficiency due to higher energy consumption. Jute - Wheat and Jute - Rapeseed - Rice can be considered suitable for small and marginal farmers because of their moderate cost of production and net return with better energy use efficiency.

ZARS is also engaged with adaptability test of new cropping sequence, new crop, better variety of the existing crops, better agronomic and pest management practices and other technologies for economic viability and agricultural sustainability of this region. Extreme intensification and diversification of agriculture in this zone is the resultant of this continuous process of searching for better technologies.

Awareness Campaign

This station is participating in awareness campaign, Krishi mela, agricultural training programmes and other meetings on a regular basis for on the spot dissemination of latest scientific agricultural knowledge.

Quality Seed Prodauction and Distribution

Quality seeds of selected and improved varieties of different crops are being produced and distributed to the farmers directly or through seed supplying agencies.
