Impact of Irrigation on Agricultural Productivity of Jalpaiguri District

The success of the agriculture depends on various factors, and irrigation is one of them. India is an agrarian society, a large proportion of population relay on agriculture for their livelihood and it’s also incorporate with the economic development of the concern society. The productivity of cultivable crops also relay on irrigation facilities. Formally the cultivators relay only on groundwater for irrigation by using, Tube Well, STW, DTW, Dug Well etc. for extracting water. But with the advancement of time the development of canal irrigation helps to change the irrigation system as well as cropping patterns. Modern agriculture depends on irrigation because modern technologies have been changed the crops production which is maximum high yielding Varity seeds and its necessary irrigation. Indian agriculture mostly depends on monsoon climate. So there is a need of irrigation for the production of high yielding verities crops. The researcher has studied the Jalpaiguri district and its agricultural and irrigational pattern for understanding the present scenario of cropping pattern and production. From the study I have found Sadar, Mal, Rajganj, and Maynaguri blocks already get help of irrigation from Teesta canal project. So farmer of these blocks can practice various types of crops by the help of Teesta canal irrigation. But on the other hand, Matiali, Nagrakata, Dhupguri blocks have not received any canal irrigation. They actually relay on underground water for irrigation. Due to presence of Canal irrigation (Surface water) certain blocks like Jalpaiguri Sadar, Mal, Rajganj, Maynaguri have get benefits and the productivity of crops also affected. Rest of the blocks largely depends on Underground Water for irrigation, so there are lots of problems in agricultural practice. They are used Jharna canal irrigation and Tube well, shallow Tube well, Dug well, Deep tube well, etc. In present total gross irrigated area of Jalpaiguri districts is 109378 hectare, total net irrigated area is 72129 hectare and total canal length is approximately 284 km many farmer has been gain and they used chemical fertilizer, pesticide etc. the farmer also used the high yielding verities seeds and they get high productivity of crops. The high yielding crops is potato, tomato, Boro, paddy, radish, cabbage, coneflower, wheat etc.
