In the Bankura district, there are two Agro-Climatic zones which have been classified based on climatic conditions, rainfall, temperature, humidity and altitude accompanied by complex land forms, hydrology and soil combinations. These two climatic zones are the Undulating Red and lataritic zone and the Vindhyan Alluvial zone. The former is tropical dry, sub-humid zone having rainfall ranging from 1100 to 1400 mm and a maximum temperature of 45 degree Celsius and a minimum temperature of 100 degree Celsius normally. This region is primarily made up of an undulating landform with mounds and valleys, exhibiting different grades of laterisation process in soil formation. The soils are well drained, susceptible to soil erosion due to rapid external drainage or run off, and the soil reaction ranges from acidic in ridges and near neutral in valleys. Organic carbon content, phosphate and patas are low. Agriculture in this region is mostly rain dependant.
Prevalence of moisture stress on standing Kharif Crop in late monsoon period is very common.
In Vindhyan Alluvial Zone, soil in general is deep, texturally medium to fine, mostly acidic in soil reaction, moderately well drained, ground water deeply placed, and low in bases, organic matter, phosphate and medium in patas. Major part of the region harvests more than one crop utilizing canal irrigation as well as ground water.
Among the major crops grown here are rice, wheat, oilseeds and vegetables which occupy a major portion of the total cropped area. Among different oilseeds, rape and mustard, and sesamum are two important oilseeds grown in this district Sesamum is cultivated in 3 seasons while rape and mustard are cultivated during Rabi season. Wheat is the second most important cereal crop in the district and crop is cultivated in assured / limited irrigated areas. About 46 percent of the net cropped area is under irrigation. Most of the Pre-Kharif and Kharif rice are grown in rain-fed conditions. The gross cropped area is about 6 lakh hectares.
