Impact of Fertilizer and Pesticide use on the Productivity of Seven Major Crop in the Kaliyaganj C D Block of Uttar Dinajpur District, West Bengal, India

Abstract

The crops were cultivated in three distinct seasons of the Kaliyaganj C.D. Block in West Bengal. Present study was conducted on seven major crops (aman rice, boro rice, jute, maize, wheat, mustard and lentil) of the study area. The study was conducted during 2019 to 2020 cropping seasons. The objectives were to find out the impact of chemical fertilizer, organic fertilizer and pesticide use on yield and productivity of these crops. The correlation and regression analysis were used to access the impact of three intermediate inputs (chemical fertilizer, organic fertilizer and pesticide) on the crop productivity. Student ‘t’ test was used for testing the significance of the correlation. The study was also undertaken to work out the relative economics of the crops by analyzing the input and output costs. For this above purpose, the input and output data were collected from 120 sample plots (within 18 villages) of the study area. After all, the results suggested a clear role of fertilizer and pesticide use on the crop productivity and showed the impact of pest attack on the crops.
