Toward improving nitrogen use efficiency in rice production: the socio-economic, climatic and technological determinants of briquette urea adoption

Deep placement of briquette urea (BU) is environmentally friendly and promotes for better nitrogen use efficiency. Nonetheless, its farm-level adoption is low. This paper contributes to the existing literature on climate-smart technology adoption by examining the factors that affect the BU adoption decision using the national representative Bangladesh Integrated Household Survey (BIHS-15) dataset consisting of 3384 rice farmers in Bangladesh. BU adoption probability is higher for farms that specialize in rice production, have more assets, use mobile phones for farming and have better access to extension services. Also, empowered women have a higher propensity to adopt BU. However, living in the feed the future zone decreases adoption probability. BU adoption probability is inversely correlated with rainfall and salinity vulnerability, while the opposite is observed for cyclone and drought vulnerability. Compared to the prilled urea (PU) users, the BU adopters applied a significantly lower amount of urea. The adopters produce more and have a relatively higher return, though the differences are insignificant. The relatively high price of BU compared to PU and the associated high labor requirement dampers the benefit of adopting the technology. Reallocation of subsidies from PU toward BU could be an effective way of promoting BU technology.

Automated summary

This study examines the factors affecting the adoption of briquette urea (BU) by rice farmers in Bangladesh. The findings reveal that farms specializing in rice production, possessing more assets, using mobile phones for farming, and having better access to extension services are more likely to adopt BU. Empowered women also show a higher propensity for BU adoption. On the other hand, living in the "feed the future zone" decreases the probability of BU adoption.
