“…Our results are consistent with previous findings that the decision to jointly adopt a package of agricultural technologies has a significant and large effect on crop productivity in comparison with the adoption of individual crop technologies or the nonadoption (Teklewold et al, 2013;Kassie et al, 2015;Khonje et al, 2018;Shafiwu et al, 2022). While there is evidence that genetic improvement by itself could bring a variety of productivity and welfare impacts (Arouna et al, 2017;Zeng et al, 2017;Wossen et al, 2019;Sellitti et al, 2020), some studies have reported that the adoption of only improved crop varieties has not yielded some of the expected impacts due to heterogeneous profitability on adopting improved varieties in Kenya (Suri, 2011), unsustainable rainfall to keep the advantage of NERICA rice varieties in Uganda (Kijima et al, 2011), or inability to show their full potential due to absence of major stresses during the evaluation period (Mills et al, 2022).…”

“…Our main target is measuring the impacts associated with the adoption of MIV and chemical fertilizers. Most previous studies on the impacts of joint technology adoption in agriculture have followed a multinomial endogenous switching regression approach (e.g., Teklewold et al, 2013;Kassie et al, 2015;Khonje et al, 2018;Shafiwu et al, 2022) focusing on estimating the average treatment effects on the treated (ATT). However, we are interested in measuring the potential impacts at the scale of the adoption of these technologies.…”

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.

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

“…Moreover, existing studies (Addai et al, 2021; Danso‐Abbeam & Baiyegunhi, 2018; Lu et al, 2021; Ng'ombe et al, 2017; Shafiwu et al, 2022) have demonstrated that majority of smallholder farmers in Ghana and Africa are more likely to adopt individual agricultural technologies than multiple technologies at a given time. This is despite some evidence that adopting multiple production technologies positively impacts crop productivity and in turn higher farm incomes (Addai et al, 2021; Khonje et al, 2018; Wainaina et al, 2018).…”

“…Cumulatively, Lu et al (2021) analyzed the impact of multiple agricultural technologies on household welfare in Northern Ghana and observed that synergies amongst multiple agricultural technologies improve the welfare of smallholder farmers. Shafiwu et al (2022) found that household welfare is improved through the adoption of improved seed variety in Ghana. In fact, there is a burgeoning literature that has established positive impacts of the related agricultural technologies on smallholder farmers' welfare across SSA (Abdul‐Hanan & Anang, 2018; Adu et al, 2018; Ayodele et al, 2019; Danso‐Abbeam & Baiyegunhi, 2018; Dompreh et al, 2021; Khonje et al, 2018; Odoemenam et al, 2020).…”

Adoption of cocoa production technologies has the potential to improve productivity and welfare of smallholder producers in low‐income countries. While studies investigating synergies in agricultural technologies are growing, empirical evidence on the determinants and impacts of adopting multiple cocoa production technologies on smallholder farmers' welfare is scarce. Therefore, this study contributes by analyzing the determinants and effects of adoption of multiple cocoa production technologies on the welfare of smallholder farmers in Ghana. To achieve this, we used the multinomial endogenous switching regression and multivalued inverse probability regression adjustment models to a random sample of 2233 cocoa farmers from Ghana. The results show that various socioeconomic characteristics (e.g., farmer's age and experience), resource constraints (e.g., land ownership and credit access), market‐related factors (e.g., distance to the market), and production shocks (e.g., rainfall) influence the adoption of multiple cocoa production technologies. Furthermore, the results reveal that adopting multiple production technologies significantly improves cocoa yields, gross income, per capita consumption expenditure, and reduces household food insecurity. Therefore, policies, such as financial support, need to be aimed at improving and strengthening smallholder cocoa producers' capacity to adopt synergistic conventional and non‐conventional cocoa production technologies to maximize smallholder farmers' welfare.
