Através de pesquisa com participação do produtor, avaliou-se o efeito da adubação residual do tomateiro no custo de produção de feijão-de-vagem do Médio Paraíba Fluminense. Utilizou-se de um experimento com delineamento de blocos ao acaso, em área de cultivo prévio de tomateiro, com cinco blocos e os seguintes tratamentos: (A) adubação de 100 kg N ha-1, 50 kg de P205 ha-1 e 100 kg K20 ha-1 com o formulado 12:06:12 (normalmente usado pelo agricultor); (B) adubação de 60 kg N ha-1 com a fonte uréia, em cobertura; e (C) sem adubação. A economia no custo de produção oferecida pelo tratamento C, em relação aos tratamentos A e B, foi de US$367,17.ha-1 e US$242,12.ha-1, respectivamente. O acréscimo nas rendas oferecidas pelas adubações adicionais foi de US$850,23.ha-1 para o feijão-de-vagem adubado com fórmula NPK e US$905,48.ha-1 para o adubado com uréia. Entretanto, a renda líquida unitária e a taxa líquida de retorno financeiro do produtor de feijão-de-vagem foram ligeiramente superiores para o feijão-de-vagem não adubado (US$5,40.cx-1 e US$2,51.US$-1) do que para o adubado com fórmula NPF (US$5,38.cx-1 e US$2,48.US$-1) e ligeiramente inferior ao adubado com uréia (US$5,48.cx-1 e US$2,65.US$-1).
The objective of this participatory work was to evaluate, under farming conditions, the effect of a residual fertilization of the tomato crop on the economy of the snap bean crop in Médio Paraíba Fluminense, Rio de Janeiro state. It was conducted one experiment in na oxisol soil, with a randomized complete block design. The snap bean was planted in succession to the tomato crop, with the following treatments: (A) Fertilizer addition of the formulation 12:06:12, normally used by the farmer (100 kg N ha-1, 50 kg de P205 ha-1 and 100 kg K20 ha-1); (B) Addition of 60 kg N ha-1 using urea as N source and (C) without fertilizer application. The decresce in cost for treatment C in relation to treatments A and B were, respectively, US$367,17.ha-1 and US$242,12.ha-1. The total income increase obtained with fertilizer application were US$850,23.ha-1 and US$905,48.ha-1, respectively for treatments A and B. However, the unitary net income and the liquid return rates were larger for the treatment without fertilization ( US$5,40/box1 and US$2,51.US$-1) than the treatment with the formula used by the farmer (US$5,38./box and US$2,48/box) and slightly inferior to the urea treatment (US$5,48.box-1 and US$2,65.US$-1).

Abstract: With the expanding use of thermal assessment techniques in beef cattle, infrared thermography has become a promising tool for assessing the environment for animal thermal comfort. Goals of this study were: (1) to evaluate cattle thermal comfort in agroforestry systems with different shade availability (2) to verify the spatiotemporal variations of infrared temperature inside agroforestry systems, and; (3) to test infrared thermography as a potential tool to assess animal thermal comfort indices in agroforestry systems. A trial was carried out between June 2015 and February 2016, covering Central-Brazil's dry winter and rainy summer seasons, respectively. The experimental area of Embrapa Beef Cattle is located in Campo Grande (Mato Grosso do Sul), coordinates 20º24'53" S, 54º42'26" W and 558 m altitude. The 12 ha plot has two agroforestry systems varying shade availability. Traditional Black Globe Temperature and Humidity Index, Heat Load Index and Radiation Thermal Load were determined, from measurements using digital thermo-hygrometers, with datalogger. Surface temperature and humidity of tree canopies and pasture were determined using an infrared thermographic camera. Results show spatiotemporal variations in infrared temperature. This means that the environment inside agroforestry systems is not homogeneously comfortable for cattle, and the system with the lowest shade availability has the greatest heat accumulation area. Weak to strong associations were identified between infrared variables and thermal comfort indices (0.08 = r <= 0.75). Positive relationships were also obtained and equally well explained by the Black Globe Temperature and Humidity Index and Heat Load Index (0.55 = R2 <= 0.94). We conclude that infrared thermography can be used as a tool to assess thermal comfort indices in agroforestry systems and to determine onset of animal thermal stress from environment and heat body accumulation.
