“…In Brazil, fruit and vegetable agribusiness enables the creation of numerous jobs, especially in the primary sector, due to the high demand for labor from planting to marketing . However, according to Cenci (2006) and Guerra et al (2017), high perishability makes difficult the marketing of fruits and vegetables.…”

The production of fruits and vegetables is listed as one of the most relevant activities in brazilian agricultural conjuncture. However, the amount of losses occurring along the production chain is alarming, especially in the postharvest stage. Thus, it was aimed to conduct a survey of postharvest losses and characterize the scenario of commercialization of fresh produce in the retail market of seven cities in the east of Maranhã o state. This work was carried out through direct interviews with 145 traders. The questionnaire with objective questions that covered socioeconomic aspects, handling, flow, conditioning, storage, marketing, and postharvest losses was applied to them. It was found that the traders had little schooling (92% of traders do not have a high school level) and lack adequate technical knowledge of produce, management, and marketing of fruit and vegetable produce. The traded vegetables are sourced from Piauí , Bahia and Ceará , and drained through canvas-covered trucks (86%). The three vegetables with the highest loss estimates are bell pepper (16.42 ± 2.21%), lettuce (11.79 ± 0.42) and tomato (11.38 ± 0.19%). Though, for fruits, it highlights plum (35.65 ± 1.34%), papaya (17.93 ± 3.79%) and guava (15.63±2.79%). 337 Among the causes, those of physiological order was the most impacting. The largest losses of vegetables occurred in Coelho Neto (17.78%), Timon (13.46%) and Brejo (10.73%) cities. Regarding fruits, the order was Coelho Neto (11.48%), Brejo (11.27%) and Timon (10.84%). There is a need for better training and awareness of traders regarding the adoption of good post-harvest practices and proper management of the commercial activity, as a way to increase the profitability of this activity, which on average is equivalent to two minimum wages per month.

“…A ocorrência do tamanho desuniforme do fruto de pimentão quando no momento da colheita é considerada como uma das principais fontes de variações em experimentos em campo com esta cultura (GUERRA et al, 2017). Em resultados apresentados em pesquisa realizada com a cultura e nas condições em que foi realizado o trabalho, concluíram que a matéria orgânica teve um efeito significativo na produção de pimentão aumentando a produtividade (CASAIS et al, 2018).…”

RESUMOO pimentão Capsicum annuum L (Solanaceae) está entre as hortaliças mais consumidas no Brasil. Diante disto o presente trabalho teve como objetivo verificar produção comercial em cinco cultivares de pimentão no município de Cruzeiro do Sul -Acre, em condições de clima tropical. O experimento foi conduzido na Universidade Federal do Acre, Campus Floresta, no município de Cruzeiro do Sul, Acre em condições de ambiente protegido (casa de vegetação). O delineamento experimental empregado foi de blocos inteiramente casualizados com cinco tratamentos e quatro repetições, em que os tratamentos adotados foram diferentes cultivares de pimentão, sendo: All big (vermelho), Alongado amarelo, Proveito, Amarelo alegria e Rubi gigante. Com base nos resultados obtidos verificou-se que houve diferença significativa (p<0,05) no formato (comprimento, diâmetro e número de frutos) dos frutos, a cultivar amarelo alegria apresenta comprimento e número de frutos maiores, enquanto as cultivares All Big e a Rubi Gigante apresentam diâmetros superiores. Em relação à produção (kg ha -1 ) em massa fresca dos frutos, verificou-se que não houve diferença significativa (p>0,05) entre as cultivares, portanto, é mais rentável o plantio da cultivar Rubi gigante, pois apresentou produção maior de frutos e menos rentável a comercialização de frutos da cultivar alongado amarelo.

“…According to Guerra et al (2017), although mechanical losses are analyzed individually, they may have contributed to increased guava metabolic activity, with inherent losses to commercialization. In view of adverse environmental conditions with a mean temperature of 28 ° C and low relative humidity, 67%, the ethylene synthesis, and respiration may increase, promoting the rapid ripening of the fruit.…”

As it is climatic fruit, guava has a short postharvest shelf life, that limits its marketing. The aim of the present work was to conduct a survey about the commercialization scenario and estimation of postharvest losses of guava in Chapadinha (MA). The research carried out in November 2016, through interviews in 12 groceries stores and 2 supermarkets in the city of Chapadinha (MA). For this, a questionnaire consisting of 13 objective questions that covered aspects about the origin, trading volume, causes, and estimation of guava losses was used. At the end of the study, it was found that 95% of guava sold in Chapadinha comes from the city of Tianguá (CE). Postharvest losses were estimated at 21% for supermarkets and 17% groceries stores. Physiological (accelerated ripening) and mechanical (kneading) factors were mainly responsible for guava losses. The damage caused can be mitigated by the adoption of good post-harvest practices and administrative management, which have the potential to be disseminated by training courses.
