Perdas quantitativas de amendoim nos períodos do dia em sistemas mecanizados de colheita

Abstract: ResumoA operação de arranquio mecanizado de amendoim é considerada crítica em função de fatores relacionados à cultura e fatores intrínsecos às máquinas utilizadas, que podem acarretar elevados níveis de perdas. As perdas acontecem no arranquio e no recolhimento do amendoim. Objetivou-se quantificar as perdas em dois períodos de realização da colheita (manhã e tarde), para conjuntos mecanizados. A colheita foi realizada na safra de 2009/2010, em área da fazenda Contendas, localizada no município de Taquariting… Show more

“…An average weighted increase of 1.08% per year was thus estimated in prices. Yield was determined by the means of the interviews, with a production of 5.68 t ha -1 (higher than the national average), which is compatible with other studies (Compagnon et al, 2013;Cavichioli et al, 2014). It should be noted that the following discounts are applied to the revenue: i) FUNRURAL Fund (2.3%); ii) quality deductions (impurity and grain quality -3%); iii) transport (R$ 1.8/free sack).…”

“…The cultivated areas are concentrated in two traditional regions: Alta Mogiana (Ribeirão Preto and Jaboticabal region) and Alta Paulista (Marília and Tupã region), where the crop finds space in the renewal of cane fields and pastures (Cavichioli et al, 2014). Renewal areas are mainly cultivated by land tenants, where third parties cultivate peanuts in the sugarcane off-season (Barbosa et al, 2014).…”

“…This fact can be attributed to the lower water content at the mo ment of harvesting, while in the conservationist tillage the reduction in the water content of the pods (curing period) may take longer, since the presence of a greater vegetal cover provided in this type of soil preparation allo ws a greater accumulation of water content in the lines, which makes it difficu lt to detach the seedlings from the branches at the time of harvest. For one of the main factors that causes losses in the peanut collection is the high water content present in the lines (Cavichio li et al, 2014).…”
