“…Entretanto, somente o tempo de manobra convencional -sem ajuda do equipamento de navegação -gira em torno dos 50 segundos. A modernização do sistema de mecanização reduziu o custo, como asseguraram SICHONANY et al (2011).…”

“…A mecanização representa o segundo componente no custo de produção, na atividade rural, perdendo apenas para os insumos, e em termos de potencial para redução pode ser considerado como o fator principal (SICHONANY et al, 2011). Assim, há a necessidade de medir o próprio desempenho de modo sistêmico e utilizar as informações para elevar a eficiência no processo (PELOIA & MILAN, 2010).…”

RESUMO:Os sistemas de navegação por posicionamento global (GPS) estão cada vez mais presentes no campo, prometendo diminuir os custos operacionais do agricultor. O objetivo deste trabalho foi avaliar o tempo de manobra durante a operação de semeadura da soja sem e com sistema de navegação. O delineamento experimental foi inteiramente aleatorizado, com dois tratamentos e doze repetições. Os tratamentos consistiram no tempo das manobras feitas de modo convencional e utilizando-se do sistema de navegação por GPS acoplado num piloto automático. Avaliaram-se o tempo de manobra e o retorno econômico. As manobras realizadas com auxílio do sistema de navegação foram, em média, 49% mais rápidas do que as manobras realizadas de forma convencional. Houve economia de R$ 4,15 por hectare, em áreas com comprimento médio das passadas de 800 metros. No caso de áreas menores, com comprimento de 50 metros, esta economia chegou a R$ 19,90 por hectare. Concluiu-se que o uso de sistema de navegação por satélites, em conjunto com piloto automático, pode gerar economia significativa de tempo e no custo operacional da semeadura. PALAVRAS-CHAVE: agricultura de precisão, piloto automático, viabilidade econômica. SEEDING MANEUVERS USING NAVIGATION SYSTEMABSTRACT: GPS navigation systems have been increasingly found in farming activities, promising lower farmer operational costs. Therefore, this research focused to evaluate the maneuvering time during soybean sowing. The experiment was set in an entirely randomized design with two treatments and twelve replications. The treatments consisted of recording maneuver time spent in conventional sowing and with a GPS navigation system coupled to an autopilot. We evaluated the operation time and the economic return. The maneuvers performed with the aid of navigation system were, on average, 49% faster than those carried by conventional system. We observed a cost saving of R$ 4.15 per hectare in areas with 800-m long lines. Moreover, areas with shorter lines (50 meters), such saving reached a value of R$ 19.90 per hectare. Thus, the use of satellite navigation system combined with an autopilot device can generate significant saving in time and operational costs in soybean cropping.

“…Moreover, the planning of spraying routines could also avoid unfavorable weather conditions and improve application efficiency, reducing agrochemical losses and maximizing operational costs, among others. According to Dash & Sirohi (2008), Sichonany et al (2011), and Akinnuli et al (2014), agricultural mechanized operations should be planned and managed previously for punctuality, without under-or overloading machinery and having minimal operational costs.…”

Brazil is the largest sugarcane producer worldwide. In mills, sugarcane crops are sprayed with agrochemicals using self-propelled, tractor-driven, and aerial hydraulic sprayers. As sugarcane spraying is regularly performed over extensive areas, the machinery to be used should be planned and dimensioned to ensure timely operations without overloading and at lower costs. Therefore, the current study aimed to analyze the operational and economic performances of different hydraulic sprayers to perform sugarcane crop control. As long as meeting our goal in field conditions would be difficult, we opted to develop a computational model, named as "TratoCana", using a spreadsheet and programming language. The model was used to assess economic and operational factors by generating scenarios and analyzing probable routine errors. In short, the results evidenced that initial value and operation speed are factors with the strongest impact on the costs of self-propelled sprayers and tractor-sprayer sets. Yet, the aerial application was mostly affected by fuel costs and crop row lengths. Moreover, the larger the spray tank volume, the lower the costs.

“…Therefore, in the properties that use mechanization in the production, the monitoring of the work done by agricultural machines and implements should deserve more attention (Sichonany et al, 2011). An adequate purchase of agricultural machinery is not enough if its use is not monitored in operational and financial aspects (Piacentini et al, 2012).…”

ABSTRACT:The aim of this study was evaluate the longitudinal distribution of maize seeds using a seeding line prototype, whit a microcontroller data acquisition system, at different speeds and types of horizontal feeder discs. Initially it was constructed a prototype simulator of seeding line, in the laboratory, and mounted two systems of microcontroller data acquisitions with infrared sensors for maize seeds counting. A test was conducted in a completely randomized design in split plots with factorial scheme of treatments 5 x 2 x 2, being the parcel two types of microcontroller data acquisition systems (infrared sensors in parallel and an diffuse infrared sensor), the factors were two feeder discs of maize seeds (inclined and normal) and five sowing speeds (3.0, 4.0, 5.0, 6.0, and 8.0 km h -1 ), with three replications, totaling 60 plots. The results showed that the data acquisition systems presented efficiency higher than 93% in the perception of the seeds. The lower speeds provided a seed distribution closer to the desired. The spacing average error between seed with the microcontroller data acquisition system with diffuse sensor was 0.0206 meters and the system with infrared sensors in parallel was 0.0158 meters.
