Resumo: | The adjustment of the spray volume according to the volume of vegetation has exhibited a way to make the most efficient pesticide applications. However, for the adoption of this method for the coffee, the determination of the volume index is still needed. Thus, the aim was to determine the volumetric rate of spraying for coffee (Coffea arabica ). The treatments were arranged in blocks following factorial (5 x 5), five spray volumes (200, 300, 500, 600 and 800 L ha-1) and five vegetative volume (TRV) with four replicates. We conducted the evaluation of leaf density prior to the application of treatments in three development stages (filling, maturation and post-harvest fruit). We analyzed the spray deposition (SD), density of the droplets (DD), the volumetric median diameter (VMD) of the droplets and relative amplitude (SPAN) of droplet spectrum. The applied spray volumes were converted to volumetric index (VI). There was no interaction between TRV and water volume (p> 0.05) for the variables SD and DD answers. In the evaluation performed during the maturation stage, leaf density was 29% higher at the time of post-harvest and the maximum SD obtained was 0.74 cm 2 uL. The VMD medium obtained was 217 m and the span 1,1. The adjustment of the curve DD according VI allowed to estimate a reduction of up to 47% of the spray volume applied. It was concluded that the VI set according to the changes in leaf density reduces the spray volume applied to coffee plantations. |

Porém, para adoção deste método para o cafeeiro ainda é necessário a determinação do Índice volumétrico. Assim, objetivou-se determinar do índice volumétrico de pulverização para a cultura do café (Coffea arabica .) Os tratamentos foram dispostos em blocos seguindo fatorial (5 x 5), sendo cinco volumes de calda (200; 300; 500; 600 e 800 L ha-1) e cinco volumes vegetativos (TRV), com quatro repetições. Realizou-se a avaliação de densidade foliar previamente às aplicações dos tratamentos em três estádios de desenvolvimento (enchimento, maturação e pós-colheita dos frutos). Analisou-se a deposição de calda (DEP), densidade de gotas (DEN), diâmetro mediano volumétrico (DMV) das gotas e amplitude relativa (SPAN) do espectro de gotas. Os volumes de calda aplicados foram convertidos em índice volumétrico (IV). Não houve interação ente TRV e volume de calda (p > 0,05) para as variáveis respostas DEP e DEN. Na avaliação realizada durante o estádio de maturação, a densidade foliar foi 29% superior à época de pós-colheita e a DEP máxima obtida foi de 0,74 µL cm-2. O DMV médio obtido foi de 217 µm e o SPAN de 1,1. O ajuste da curva de DEN de acordo com o IV permitiu estimar uma redução em até 47% do volume de calda aplicado. Concluiu-se que o ajuste do IV de acordo com as variações de densidades foliares permite reduzir o volume de calda aplicado em lavouras de café.2017-03-302017-08-01T20:08:46Z2017-08-01T20:08:46Z2017info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfSOUSA, J.
