Shoot grafting (grafting) on plants is a cultural technology that reduces production time compared to new planting methods. This has changed the habits of local coffee farmers, who previously carried out plantation activities only when entering the harvest season, to become more intentional because, generally, the nature of grafting coffee requires intensive attention and care to continue to bear fruit throughout the season. This research aims to analyze the impact of applying grafting to local varieties of coffee plants, especially in smallholder plantations, on the resulting production. Multi-stage sampling was used to choose326 coffee farmers divided into two farming groups, namely 120 farmers from the group of farmers who have implemented shoot grafting (as the treatment group) and 206 farmers who have not implemented shoot grafting or as the control group. The probity model estimates the probability of grafting and then chooses a matching algorithm. In the matching process between covariates, the nearest neighbor without replacement (NN) technique is a matching process for each covariate with only one chance. The results show that grafting technology has not significantly impacted the production of locally cultivated coffee. However, applying top grafting technology influences the number of plants and farmer experience.

Impacto da enxertia na produção local de café baseada em plantações populares na Província de Bengkulu, Indonésia
RESUMO: A enxertia de brotos em plantas pode ser considerada como uma técnica de manejo cultural para reduzir o tempo de produção quando comparado aos novos métodos de plantio. A adoção dessa técnica, provocou uma mudança nos hábitos dos cafeicultores locais na Indonésia; antes, esses produtores realizavam atividades de manejo apenas no início da época de colheita; agora, precisaram se tornar mais intensivistas, visto que a enxertia do café exige atenção e cuidados frequentes para continuidade da produção de frutos ao longo do ano. temporada. Esta pesquisa tem como objetivo analisar o impacto da aplicação de enxertia em variedades locais de café na Província de Bengkulu (Indonésia), especialmente em plantações de pequenos agricultores e nas suas produções resultantes. A amostragem ocorreu em vários estágios e foi usada para escolher 326 cafeicultores, divididos em 2 grupos agrícolas, sendo: i) 120 agricultores que implementaram a enxertia de brotos (como grupo de tratamento); ii) 206 agricultores que não implementaram a enxertia de brotos. Um modelo probabilidade foi usado para estimar a probabilidade de enxerto e, em seguida, escolher um algoritmo de correspondência. No processo de emparelhamento entre covariáveis, foi empregada a técnica do vizinho mais próximo sem substituição (NN), que indica que o emparelhamento para cada covariável possui apenas uma chance. Os resultados mostram que a aplicação da tecnologia de enxertia provou não ter impacto significativo na produção do café cultivado localmente na Indonésia; porém, a aplicação da tecnologia de enxertia de topo, mostra influências no número de plantas e na experiência do agricultor.
