1. Changes in leaf appearance and developmental phases associated with breeding progress in six-rowed barley in the Pannonian Plain
Abstract The aim of this study was to analyze traits of leaf appearance and phenological development related to grain yield gain in winter barley cultivars released over the past 50 years. Field trials with 15 six-rowed winter barley cultivars were conducted during two growing seasons. The main leaf appearance and developmental traits were studied. The durat

2. Mapping of spatiotemporal distribution of Tibraca limbativentris Stal (Hem.: Pentatomidae) in flooded rice crop in Southern Brazil
ABSTRACT The rice stem bug, Tibraca limbativentris Stal (Hem.: Pentatomidae), is one of the main insect pests in Brazilian rice crops. Knowledge of its spatiotemporal distribution can support the development of an effective sampling system and improve IPM strategies. This study aimed to map the spatiotemporal distribution of rice stem bug in flooded rice cro

3. Phenological study of populations of Cnidoscolus quercifolius in the Western Seridó, Paraiba state, Brazil
Resumo Padrões fenológicos de duas populações de Cnidoscolus quercifolius foram avaliados em área de caatinga no Seridó Ocidental, estado da Paraíba, Brasil, no período de março de 2009 a fevereiro de 2011, com dados coletados mensalmente. As avaliações abordaram uma análise quantitativa dos índices de atividade em períodos vegetativo (brotamen

4. RELATIONSHIP BETWEEN COFFEE CROP PRODUCTIVITY AND VEGETATION INDEXES DERIVED FROM OLI / LANDSAT-8 SENSOR DATA WITH AND WITHOUT TOPOGRAPHIC CORRECTION
ABSTRACT The reflectance values of a coffee crop are influenced by several factors such as planting direction, crop spacing, time of the year, plant age and topography which reduces the accuracy of the estimates derived from remote sensing data. In this context were evaluated the relationships between coffee productivity and values of NDVI, SAVI and NDWI veg

5. Source-sink relationships in two soybean cultivars with indeterminate growth under water deficit
Abstract Water deficit is a major factor limiting crop yield in rainfed areas. We hypothesized that under water deficit the decrease of photosynthetic production stimulates: carbohydrate remobilization from leaves, stems and roots to reproductive organs; and decreasing flowering intensity and pod development. The present work aims to study the effect of wate

6. Fructan dynamics in the underground organs of Chresta exsucca (Asteraceae), a dry season flowering species
ABSTRACT Climatic seasonality has an influence on the phenology of native Cerrado plants. Herbs and subshrubs tend to flower in the rainy season, although some species of these habits flower in the dry season. Reserve carbohydrates, stored in the underground organs, are used to support phases of high energy-demand, but also may protect plants from damage dur

7. Energy balance and evapotranspiration of melon grown with plastic mulch in the Brazilian semiarid region
Melon plants (Cucumis melo L.) are grown in the state of Rio Grande do Norte (RN), the largest producer of melons in Brazil, with plastic mulch and agrotextiles. Studies of crop evapotranspiration (ET) under these conditions are required to ensure adequate irrigation. This study aimed to determine the crop coefficients (Kc) of irrigated melon plants grown wi

8. Ocorrência, distribuição geográfica e estudo fenológico de camu-camuzeiro (Myrciaria dubia (H.B.K.) Mc Vaugh no estado de Roraima / Occurrence, geographical distribution and phenological study of (Myrciaria dubia (H.B.K.) McVaugh) in the state of Roraima
The camu-camu (Myrciaria dubia) is a representative of the family Myrtaceae, one of the botanical families most important to fruit growing and which is part of several communities of the Brazilian vegetation. M. dubia is an Amazonian plant, found most often in the Peruvian Amazon. The species possesses fruits with a high content of vitamin C, the pulp being

The yield of asparagus beanr (Vigna unguiculata spp. sesquipedalis (L.) Verdc.) is an excellent alternative source of income for producers of the state Amazonas, since its consumption is very expressive in the region. However, they are virtually nonexistent in the literature about the behavior of the crop when grown under different conditions of soil moistur

10. Modelo para previsão do florescimento na cultura da soja
Soybean crop have a great economic importance in the world and have a large cultivated area. With the intensification of agriculture and the quest for increased productivity, know the date of occurrence of phenological stages is crucial and allows the management and applications of herbicides, insecticides, fungicides and nutrients at the right time, in addi

11. Calibração e avaliação do modelo ORYZA-APSIM para o arroz de terras altas no Brasil / Calibration and evaluation of the ORYZA-APSIM model for the upland rice in Brazil
With the purpose of calibrating and evaluating the ORYZA-APSIM model for the upland rice in Brazil, seventeen field experiments were carried out at EMBRAPA Arroz e Feijão, in four upland rice Brazilian regions (Santo Antônio de Goiás-GO, Sorriso-MT, Gurupi and Teresina-PI), from 2005/2006 to 2008/2009 seasons. The model was calibrated and evaluated for an
