Munshiganj:The Department of Agricultural Extension (DAE) has initiated a program to promote balanced fertilizer use among potato farmers in Munshiganj. The initiative aims to lower production costs, conserve soil fertility, and ensure sustainable agricultural practices.
According to Bangladesh Sangbad Sangstha, farmers in Munshiganj could save approximately 39,054 metric tons of chemical fertilizers each season, valued at around Taka 312 crore, by adhering to the recommended application rates set by the Bangladesh Agricultural Research Institute (BARI).
Munshiganj, previously the top potato-producing district in the country, now ranks third behind Rangpur and Bogura. Despite this, it remains a key supplier of specialized potato varieties. Potato cultivation spans 34,000 to 35,000 hectares annually, representing a primary cash crop for many local farmers. Currently, farmers use about 72,034 metric tons of fertilizer annually, whereas BARI recommends only 32,980 metric tons based on specific factors like soil conditions and potato varieties.
BARI's recommendations include applying 250-300 kg of urea, 150-200 kg of TSP, 250-300 kg of MOP, 100-150 kg of gypsum, and 10 tonnes of compost per hectare. However, many farmers exceed these amounts in hopes of achieving higher yields. Ajmir Hossain, a farmer, noted that a typical mixture of fertilizers is applied per gonda of land, often totaling 2.11 metric tons per hectare.
Dr. Md Habibur Rahman of the DAE emphasized that excessive fertilizer use raises costs and harms soil nutrient balance. The DAE's initiative includes demonstration plots, soil testing, and training programs to educate farmers on balanced fertilizer management. The goal is to correct misconceptions about fertilizer application and promote sustainable practices that maintain good yields while reducing costs.
