摘要：Soil is the principal medium of plant growth for providing nutrients in adequate manner. At the dawn of the civilization, agriculture based sedentary civilizations have been grown up in fertile soil of the river. Over time, with the increase of population and food demand, methods of agriculture and stress on soil have been accelerated simultaneously because of mismanagement of soil fertility. Declining soil fertility has become a threat in agricultural productivity and agro-economic scenario. In this study, soil fertility and factors of agricultural productivity have been studied in Sapar Mouza where double cropped paddy is cultivated for last 35 years using inorganic fertilizer. Declining soil fertility has created an adverse effect on productivity of paddy. Soil pH is an important factor for productivity followed by phosphate and nitrogen content in soil. Phosphate, organic carbon and potassium are the main three components of production system of paddy which has shown that not only chemical fertilizer but also organic manure can sustain the productivity of paddy. Hence, integrated management of chemical fertilizer and organic manure are essential for sustainability of agricultural productivity of the mouza.
