“…Our results show a positive association among various extension strategies used by PECs under the SAT Program and AI. The findings show that the number of visits by an extensionist per year is directly proportional to the adoption of technologies [43]. Our results regarding the number of visits are inconclusive and in contrast with those of several authors (see Table 1), but we found that the duration of each visit had a significant and positive association with increased technology adoption.…”

Extension services play a crucial role by improving skills and access to information that result in greater farm level innovations, especially on family farms which are the predominant form of agriculture in the world. This study analyzed the connection between strategies implemented by extension services and technology adoption on family farms. Using the case of the Servicio de Asesoría Técnica (SAT) Program, we developed a bottom-up adoption index (AI) for vegetable and berry farmers in three regions of Central Chile. We implemented 10 focus groups totaling 101 participants, all recipients of technical assistance from private extension companies (PECs) funded by the SAT Program. After the focus group sessions, we surveyed participating farmers to gather information on socio-economic attributes and adopted technologies. Using cluster analysis, we identified three groups of farmers according to their adoption intensity. The results indicate that extension strategies used by PECs have distinct effects on the adoption of new technologies. Higher adoption indexes were positively associated with the duration of the extension visits, the number of group activities, and the use of incentives and credits provided by the Chilean government. The value of production and farm size were positively associated with adoption intensity.

“…In SSA, Chekene and Chancellor (2015), Nakano et al (2018) and Nonvide (2021) noted that farmers' education, age, farming experience and training on improved rice production practices were important in the adoption of improved rice production technologies among rice farmers. Similarly, Fosso and Nanfosso (2016), Hassan et al (2016) and Lulseged et al (2016) showed household wealth, off-farm employment, farm size, participation in on-farm trials, and farmers' education to be associated with adoption of improved management practices for maize, e.g., improved weed management, improved seeds, and use of fertiliser. Likewise, Dersseh et al (2016), Tadesse et al (2017), andTadesse et al (2019) observed that adoption of improved potato varieties and production practices was related to household wealth and educational levels.…”

“…The lack of or slow adoption of improved agricultural technologies is attributed to high costs, uncertainties about proper application and success under local farmers' environmental conditions, and farmers' perceptions and expectations (Mottaleb, 2018;Sinyolo, 2020). Further studies show that variation in adoption of improved management practices that enhance crop yields is related to differences in socio-economic characteristics of farm households, including, for instance, family size, farm size and income, farmers' age and education, labour availability, availability of cash for investment, and risk perception (Danlami et al, 2016;Fosso and Nanfosso, 2016;Hassan et al, 2016;Tadesse et al, 2017;Takahashi et al, 2020;Urfels et al, 2021). Moreover, past participation in on-farm trials, training and awareness about the technology, and contact with extension agents are shown to influence adoption (Danlami et al, 2016(Danlami et al, , 2019Hassan et al, 2016;Takahashi et al, 2020).…”

Due to such constraints, improved agricultural technologies may not necessarily result in poverty reduction as some of these constraints make improved technologies inaccessible and less profitable for the poorer farmers (Wossen et al, 2019).…”

Low productivity of rice in Uganda is attributed to sub-optimal production practices related to soil nutrient, crop and weed management. Application of improved management practices could enhance productivity. Returning 1 year after a joint experimentation in which different components of recommended agronomic practices (RAP) for rice were tested, we assessed change in management practices and grain yield of participating farmers (participated in joint experimentation) and non-participating farmers (did not participate) with plots in the same irrigation scheme. Participating farmers belonging to the lower-yielding farmers under farmers' practice (FP) during joint experimentation improved their management practices, compared with the middle- and top-yielding farmers. Sixty-one, 24 and 7% of lower-, middle- and top-yielding farmers, respectively, weeded earlier after experimentation compared with weeding time under FP during joint experimentation. Seventy-nine percent of lower-yielding farmers used fertiliser after experimentation compared with 18% during experimentation, with a higher N rate increase than middle- and top-yielding farmers. Overall, participating farmers transplanted and weeded earlier, and applied slightly higher N rates compared with non-participating farmers. Top-yielding farmers had significantly (p = 0.03) higher grain yield, followed by middle- and lower-yielding farmers. However, lower-yielding farmers made significantly (p < 0.001) higher yield gain than middle- and top-yielding farmers. A paired t-test showed that average yield gain was 1,358 (1,027–1,689), 473 (252–695) and −91.7 (−397–213) kg ha−1, respectively, for lower-, middle- and top-yielding farmers. Participating farmers had higher grain yield (4,125 kg ha−1) than non-participating farmers (3,893 kg ha−1). Three farm types were identified that differed in application of RAP, however, with small differences in household characteristics. The farm type with higher fertiliser use in nursery and field, line transplanting, timely weeding and higher N rate had the highest grain yield. We conclude that joint experimentation had a larger effect on raising yield of lower-yielding farmers, bringing farmers closer in their management and outputs. Lack of differences among farm households could indicate that wealth is not crucial in innovation adoption in this production system.

“…En Station de recherche à Kouaré au Burkina Faso, l'utilisation d'une variété de sorgho résistante, combinée à un inoculum de Fusarium oxysporum et à la bouse de vache a significativement réduit l'infestation de Striga hermonthica 85 jours après le semis . La productivité des champs de productions agricoles peut être améliorée grâce à une gestion adéquate du Striga (Hassan et al, 2016) et d'apport d'éléments nutritifs aux sols particulièrement l'azote qui réduit considérablement la production, par la plante hôte, d'exsudats racinaires contenant les stimulants de la germination des graines du parasite, ce qui crée des conditions défavorables au développement du parasite (Dembélé., 2009). Pour ce faire, il serait donc important d'inclure des technologies de gestion intégrée du Striga qui sont potentiellement réalisables par les petits producteurs dont les capacités techniques, matérielles et financières sont souvent très limitées.…”

Une expérimentation a été conduite dans le village de Djaroubou-Choufou au Tchad de 2011 à 2013 pour évaluer l'effet du système de culture et de la fertilisation organique sur l'infestation de Striga hermonthica et la productivité du maïs et du niébé. Un dispositif factoriel en blocks complètement randomisés (Fisher) avec trois répétitions a été utilisé pour évaluer la culture pure de maïs et l'association maïs / niébé, quatre doses (10, 20, 40 et 80 t ha-1) de compost et de bouse de vache et quatre doses (5, 10, 15 et 20 t ha-1) de fientes de chauve-souris et un témoin sans fertilisation. Les résultats ont montré que la fiente de chauve-souris et les plus fortes doses de bouse de vache et de compost affectent le développement de Striga hermonthica et améliorent le rendement grain du maïs aussi bien en culture pure qu'associée. L'étude a montré que les rendements du niébé sont plus faibles dans les parcelles amendées que dans les parcelles témoins. L'utilisation des fumures organiques a permis de mettre en évidence leur rôle dans la lutte contre Striga hermonthica et dans l'amélioration de la productivité des champs avec l'efficacité de la fiente de chauve-souris qui a été particulièrement remarquable.
