“…Feder [ 17 ] first attempted to evaluate the interaction of various agricultural technologies adopted by farmers. Recently, studies on the adoption of multiple agricultural technologies (MATs) in the joint estimation framework have begun to increase [ 1 , 18 , 19 ]. Some scholars have considered conservation agriculture (CA), climate-smart agriculture (CSA), integrated soil fertility management (ISFM), sustainable agricultural practices (SAPs), and sustainable intensification practices (SIPs) as research objects to analyze the factors of various technologies adopted by farmers [ 4 , 9 , 20 – 22 ].…”

Tobacco farmers often adopt additional multiple agricultural technologies (AMATs) in addition to implementing the standardized technical system in China. Based on the cross-sectional micro data of 346 households of Chongqing, China, this paper assesses the determinants and impacts of the adoption of AMATs on income by using a multinomial endogenous treatment effects model to correct for selection bias and endogeneity caused by observed and unobserved heterogeneity. The results show that (1) the adoption of combinations of AMATs is determined by the household head’s education level, experience in tobacco growing, the shortest distance to nearby town, the amount of technical training, the ratio of land available for mechanical cultivation to tobacco land, the distance to extension station, and the ratio of leased land. (2) The adoption of combinations of AMATs has heterogeneous effects on farmers’ income through yield and quality improvement. (3) The comprehensive combination of AMATs is not necessarily the best option for farmers. Due to the interaction between technologies such as complementary, substitute or supplementary effects, the moderate implementation of fertilizers and soil improvement is the most effective combination. The results of this research provide a scientific basis for improving the adoption efficiency of AMATs in China.

“…However, it also increased family labor demand, especially for women. Meanwhile, using a similar approach, Martey et al (2023) found that the joint use of Striga-resistant maize and fertilizers had significant positive effects on yields and food consumption. Likewise, using a similar approach, Kassie et al (2015) found evidence of improved food security and reduced downside risk when Malawian farmers simultaneously adopted maize varieties and chemical inputs.…”

Rice research and technology development in Latin America has increased yields and offered the opportunity for several countries to contribute to global food security by becoming net exporters of this cereal. In spite of the broad availability of rice technologies in the region, rice yields remain substantially low in countries like Bolivia. This study examines how Bolivian rice growers make simultaneous decisions about adopting improved varieties and chemical fertilizers and how this joint decision influences the productivity of this crop. By exploiting a nationally representative survey of rice producers, we use a multinomial logit model and an optimal instrumental variable approach to study both the correlates of technology adoption and the impacts of this adoption on rice yields. Our findings suggest that partial adoption of rice varieties or fertilizers does not affect yields, but the joint adoption of these technologies can almost double rice productivity. Promoting packages of agricultural technologies—instead of single technologies within efforts to make these technologies available for small farmers—would exploit the complementarities of different technologies and boost rice yields in Bolivia. The implications would not only be to achieve the desired self-sufficiency in rice production but also to follow similar pathways of other countries in the region that have become net exporters of rice and are contributing to Global Food Systems.
