| ABSTRACT The Mossoró-Assu-Baraúna district, Rio Grande do Norte State (RN), is recognized by the intense production of horticulture, mainly muskmelon for export. However, this region is often devastated by intense droughts. Thus, the muskmelon production is predominantly under irrigated condition and, due to constant threat of water resources collapse on the region, a rigorous irrigation water management in the region is needed. The main objective of this article was to analyze the seasonal pattern of energy balance partitioning and evapotranspiration on irrigated muskmelon crop on the region around Mossoró-RN. The study was carried out in two areas of commercial production of muskmelons in the Mossoró-Assu-Barúna district, during two growth seasons from... |

| Field-based soil moisture measurements are cumbersome. Thus, remote sensing techniques are needed because allows field and landscape-scale mapping of soil moisture depth-averaged through the root zone of existing vegetation. The objective of the study was to evaluate the accuracy of an empirical relationship to calculate soil moisture from remote sensing data of irrigated soils of the Apodi Plateau, in the Brazilian semiarid region. The empirical relationship had previously been tested for irrigated soils in Mexico, Egypt, and Pakistan, with promising results. In this study, the relationship was evaluated from experimental data collected from a cotton field. The experiment was carried out in an area of 5 ha with irrigated cotton. The energy balance and... |

| O presente estudo teve como objetivos estimar a evapotranspiração - ETc e determinar a curva do coeficiente de cultura - Kc do algodoeiro irrigado através do Surface Energy Balance Algorithm for Land - SEBAL com imagens orbitais TM - Landsat 5. Foram utilizadas oito imagens distribuídas ao longo do ciclo fenológico do algodoeiro cultivado na Fazenda Busato localiza no município de Bom Jesus da Lapa, região do Médio São Francisco, Estado da Bahia (13°15'18''S, 43°25'05''W, 436 m). A classificação climática da região segundo Köppen é BSwh'. O saldo de radiação foi calculado a partir de imagens da temperatura, emissividade da superfície, índices de vegetação, albedo e calculados os fluxos de calor no solo e sensível para obter-se o fluxo de calor latente e a... |
