ABSTRACT Remote sensing has become an important technique for spatial characterization and agricultural monitoring, in order to improve wine development and reduce production costs. The wine region of the ?Campanha Gaúcha?, Brazil, was recognized in 2020 as an Indication of Origin for quality wines. This study analyzed orbital data in a ?Cabernet sauvignon? vineyard in the municipality of Santana do Livramento. From the images of the Planet and Sentinel-2 satellites, the Normalized Difference Vegetation Index (NDVI) was evaluated, as well as its viability in viticulture in the region. Twelve images from each satellite were analyzed using digital image processing techniques, average NDVI temporal profiles were generated and analyzed by statistical methods. The generated maps produced zoning for each scene over the period studied, for both satellite images. The results showed that the two satellites were suitable for use in monitoring vineyards, due to their excellent temporal, spatial and radiometric resolution. Keywords: NDVI, precision viticulture, remote sensing, Sentinel 2, Planet IMAGENS ORBITAIS PARA CARACTERIZAÇÃO ESPACIAL E TEMPORAL DA VINHA POR ÍNDICE VEGETATIVO NA REGIÃO VITIVINÍCOLA CAMPANHA GAÚCHA, BRASIL RESUMO O sensoriamento remoto tem se tornado importante técnica de caracterização espacial e monitoramento agrícola, a fim de melhorar o desenvolvimento do vinho e reduzir os custos de produção. A região vitivinícola da ?Campanha Gaúcha?, Brasil, foi reconhecida em 2020 como Indicação de Origem para vinhos de qualidade. Este estudo analisou dados orbitais em um vinhedo de ?Cabernet sauvignon? no município de Santana do Livramento. A partir das imagens dos satélites Planet e Sentinel-2, avaliou-se o Índice de Vegetação por Diferença Normalizada (NDVI), bem como sua viabilidade em viticultura na região. Doze imagens de cada satélite foram analisadas usando técnicas de processamento digital de imagens, perfis temporais médios de NDVI foram gerados e analisados por métodos estatísticos. Os mapas gerados produziram zoneamentos para cada cena ao longo do período estudado, para ambas as imagens de satélite. Os resultados mostraram que os dois satélites são adequados para utilização na monitorização de vinhas, devido à sua excelente resolução temporal, espacial e radiométrica.

Morada Nova breed sheep are without wool, tropicalized, small-sized animals, known for their high-quality meat and skin. Their body development naturally depends on the genetic potential and adequate nutritional support, which suggests that the offer of high-energy density diets positively influences their productive indicators. Thus, the present study investigated the effect of a high-energy diet for the Morada Nova lambs on body development and testicular function, considering their histomorphometric characteristics and seminal quality. Forty-two males (19.2 weeks, 20.7 ± 3.5 kg) were equally divided into two groups and fed with 2.05 Mcal (G7, n = 21) or 2.37 Mcal (G24, n = 21) of metabolizable energy/day, equivalent to 7% and 24% above the minimum for growing lambs. The animals were confined for 23 weeks (W0 to W23). Weight and body score differed significantly from the W1 (P < 0.05). From the W5, thoracic perimeter, body length, wither height, and rump attributes were higher in G24 (P < 0.05). The scrotal circumference and testicular volume were higher in G24 from the W3 (P < 0.05). Although testosterone levels were not affected (P = 0.05), the highest energy intake increased the diameter of the seminiferous tubules and the development of the epididymal epithelium (P < 0.05). This positively influenced the seminal quality and reduced the minor defects (21.87%vs. 17.13%) and the total spermatic defects (26.34%vs. 21.78%, P < 0.05). Thus, it is possible to employ higher levels of dietary energy for Morada Nova young males to express higher productive efficiency and earlier reproductive attributes of interest.
