| A common bean (Phaseolus vulgarisL.) cultivar must combine desirable genotypes for several traits in order to be accepted by producers and consumers. This study aimed to evaluate selection efficiency when segregating bean populations for traits, by means of a selection index, in order to obtain superior progenies for traits considered. A total of 16 populations from the F4 and F5generations were evaluated in 2011 and 2012, respectively. The traits evaluated were plant architecture, plant disease, grain type and yield. Using standard scores (Z), the sum of the four traits (∑Z) was obtained and, based on this information, the best populations were identified. The evaluation of selection effectiveness was performed on 31 progenies from each population. The... |

| A biomassa é um parâmetro agronômico estratégico utilizado para indicar o status de crescimento da cultura, por causa dos efeitos das práticas de manejo agrícola. A metodologia convencional para se obter a biomassa ocorre por métodos destrutivos, que requerem a colheita manual das plantas, pesagem e secagem em estufa, inviabilizando as medidas em grandes áreas de produção. Como alternativa, recomendam-se técnicas de sensoriamento remoto com imagens aéreas adquiridas por drones, com boa precisão, economia de tempo e mão de obra. O estudo teve como objetivo a proposição e validação de modelos de estimativa da biomassa seca de plantas de milho, usando-se a altura das plantas extraída de modelos digitais de superfície (CSM) gerados de imagens aéreas de câmera... |

| ABSTRACT The main objective of this study was to evaluate the agronomic characteristics of commercial maize hybrids with modern and old architecture, under the influence of nitrogen (N) as top dressing with different plant populations. Two independent experiments were conducted, one in the municipality of Guarapuava (reduced spacing = 0.45 m) and the other in the municipality of Laranjeiras do Sul (conventional spacing = 0.90 m), in the Paraná state, Brazil, in the 2012/2013 growing seasons. The experiments were set in a randomized block design, with three replicates, in a factorial scheme (6 x 3 x 3), corresponding to six maize hybrids (with modern and old architecture), three plant populations (60000, 75000 and 90000 plants ha-1) and three N doses as top... |

| The effects of paclobutrazol on the height of Petunia × hybrida hort. ex E. Vilm. were studied. An experiment on 'Bravo F1' was performed at the National Institute for Agricultural Technology (INTA), San Pedro Agricultural Experimental Station (33º4 S, 59º4 W), Buenos Aires Province, Argentina, in the spring of 2006. Treatments consisted of three colours of flower (white, red and blue), four concentrations of paclobutrazol by irrigation (0, 5, 10 and 15 mg L-1 and three application times (at 10-12, 18-20 and 26-28 leaves). Height at 45 d after transplanting (dat), days to appearance, opening and fall of the first flower and number of flowers at 21 and 45 dat were registered. Differences between control plants due to flower colour were detected, and would... |

| ABSTRACT This study was performed to introduce the allele Bush of commercial cultivars with a bush growth habit into Cucurbita moschata accessions and select the best crossings for production potential and standard fruit shape “Menina Brasileira” through general combining ability (GCA) and specific combining ability (SCA). To determine GCA and SCA, a partial diallel analysis was performed. The parental group (group I) consisted of two cultivars containing the dwarfism bush gene, and the second group (Group II), formed by five accessions of UFV Vegetable Germplasm Bank, with high production potential and fruit shape “Menina Brasileira”. We evaluated: productivity (PROD), fruit shape (FORM), growth rate until the 50th day after transplanting (CRESC), and... |

| Baccharis dracunculifolia, the host plant of the gall maker Neopelma baccharidis Burck., is locally distributed in delimited patches. The effects of the host plant individual (plant height, crown diameter, and crown volume), local (host plant patch), and regional (locality) characteristics on the number of galls were analyzed, in Viçosa (three patches) and in Rio Doce State Park, Marliéria (two patches), Minas Gerais State (20°45'S, 42°50'W; and 19°50'S, 42°30'W, respectively). The number of galls/individual plant increased homogenousliy with plant dimensions on local and regional scale. Gall load was also homogenous, but the proportion of galled plants differed on a local scale. The differences were related to local plant size differences, and not to host... |

| Abstract Brazil is the largest producer of passion fruit worldwide, however diseases have been reducing passion fruit productivity, and limiting its cultivation for several years in a row in the same area. The proposal of this study was to evaluate diseases intensity and productivity of yellow passion fruit in vertical and overhead trellis systems, during two seasons, in annual cycle. The experiment was realized in a commercial orchard of yellow passion fruit in the municipality of Araquari, SC, in the 2013/14 and 2014/15 seasons. The treatments were vertical and overhead trellis systems, tested in a randomized complete block design, with eight replications. The agronomic practices were performed according to the culture recommendations and naturally... |
