| Abstract. Knowledge of the agricultural calendar of crops is essential to better estimate and forecast the cultivation of large-scale crops. The aim of this study was to estimate sowing date (SD), date of maximum vegetative development (DMVD), and harvest date (HD) of soybean and corn in the state of Paraná, Brazil. Dates from 120 farms and the Enhanced Vegetation Index (EVI) from the Moderate Resolution Imaging Spectroradiometer (MODIS) from 2011 to 2014 were used into a seasonal trend analysis to obtain soybean and corn seasonal patterns. The results indicate that the majority soybean is sown during October and the DMVD occurs between the second ten-day period of December and the first ten-day period of January. Owing to the spatial variability of the... |

| No Estado do Acre, a mandioca tem grande importância econômica e social, constituindo-se num dos principais produtos básicos da alimentação da população, principalmente na forma de farinha, mas com grande potencial também para o consumo in natura. O objetivo deste trabalho foi avaliar genótipos de mandioca em diferentes épocas de colheita no Estado do Acre. Foram avaliados dez genótipos de mandioca em quatro épocas de colheita utilizando o delineamento de blocos casualizados com quatro repetições, em esquema de parcelas subdivididas, sendo as épocas as parcelas e os genótipos as subparcelas, nas safras 1999/2000 e 2000/2001. Os genótipos MD-33 e Pão apresentaram alto rendimento de raízes e resistência à podridão radicular; o primeiro é indicado para a... |

| Determining the harvest date of table grapes is very important to achieve high-quality bunches with adequate soluble solids content, low titratable acidity, and high concentrations of polyphenols. Table grape consumption has increased worldwide due to its phenolic compound content and its beneficial effects on human health. Thus, this study aimed to characterize the phenolic ripening of ?BRS Vitoria? seedless table grapes at different ripening stages using HPLC?DAD?ESI-MS/MS. For this purpose, a trial was carried out during 2016 in a commercial vineyard of ?BRS Vitoria? seedless grape located in Marialva, state of Parana (Southern Brazil). Berry samples were assessed weekly, starting at v ́eraison until full ripeness. At each ripening stage, the... |

| The use of cassava genotypes low-yield coupled with inappropriate harvest times lead to the country?s low average yield. This study aimed to evaluate the agronomic characteristics of cassava genotypes at different harvest times in the Recôncavo region of Bahia. The experiment was conducted during two crop cycles in Cruz das Almas, Bahia, with eight cassava genotypes (BRS Poti Branca, BRS Caipira, BRS Kiriris, BRS Verdinha, BRS Tapioqueira, 9624-09, 98150-06 and 9783-13) were evaluated at different harvest times. The characteristics yield of shoot, root, flour and starch, root dry matter and harvest index were evaluated, as well as their correlation with the harvest time. Data were submitted to analysis of variance and fitted to linear regression models.... |

| ABSTRACT A database of maturity and quality indices was built by analysis of 62,807 samples of 100 ‘Gala’ apples and 29,053 samples of 100 ‘Fuji’ apples at harvest, over 11 years (2005-2015) in an apple industry warehouse. Apple fruit were harvested in Fraiburgo (SC), São Joaquim (SC) and Vacaria (RS). Data on firmness, starch index (SI), soluble solid content (SS), titratable acidity (TA), size and grades (external appearance) of apple fruit were submitted to linear and nonlinear regression analyses. Each fruit was graded by analysis of external qualities (color and surface blemishes) following Brazilian legal standards. At apples industry, the harvest period extended from 3rd to 15th week of the year for ‘Gala’ and from 10th to 22nd week of the year for... |
