| Abstract The objective of this work was to evaluate the agronomical performance of 'Piemonte' mandarin grafted on 11 rootstocks grown under the edaphoclimatic conditions of the Coastal Tablelands, in the state of Sergipe, Brazil. The following combined agronomical parameters were evaluated: vegetative growth, abundance of phytophagous mites, plant yield, drought tolerance, and physicochemical quality of fruit. 'Piemonte' mandarin had the best productive performance when grafted on 'Santa Cruz Rangpur' lime, 'Red Rough' lemon, 'Sunki Tropical' mandarin, and 'Riverside' citrandarin, and it was more tolerant to drought when grafted on 'Santa Cruz Rangpur' lime and on the LVK x LCR-010 hybrid. Rootstocks did not affect pest population levels. 'Piemonte'... |

| ABSTRACT The aim of this study was to examine the early performance of ‘Kampai’ and ‘Rubimel’ peach on 3 training systems. The study was conducted between 2010 and 2013. Treatments were the training systems ‘Ypsilon’, Central Leader, and Open Center, arranged in a randomized complete block design. Assessed parameters were production per tree, fruit weight, yield, fruit firmness, and soluble solids. The early yield and economic return are greater in Central Leader training system for both cultivars. Besides, training system does not influence fruit quality attributes. |

| High land productivity is a must for any commercial cultivation including Hevea brasiliensis (rubber). Also, the high demand for natural rubber has placed great pressure on expanding rubber cultivation to new and non-traditional areas. Understanding the ecophysiological principles behind the measures of productivity improvements is vital for wide application of these measures and to assess their sustainability. This review discusses the ecophysiological principles and tools used, along with the measures taken, to address productivity needs in terms of: genotype selection, determination of optimum planting density, and establishment of intercropping systems. Breeding for high yields and selection of suitable genotypes for different growing conditions are a... |

| The study aimed at the energetic description of wood and bark biomass of Acacia mearnsii De Wild. in two spacing plantations: 2.0 m × 3.0 m × 1.0 m and 1.5 m, during 36 months after the planting. The experiment was conducted in the municipality of Frederico Westphalen, state of Rio Grande do Sul, Brazil. Biomass (BIO), calorific value, basic density, ash content, volatile matter and fixed carbon content and energy density (ED) of wood and bark were determined. The smallest spacing plantation presented the highest production per unit area of BIO and ED of wood and bark. |

| Verificou-se o efeito de diferentes espaçamentos com suas respectivas densidades em viveiro de seringueira, na produção de mudas do tipo convencional (raiz nua). Dos resultados obtidos, conclui-se que as melhores opções de espaçamento para viveiro de seringueira, levando-se em consideração uma maior produção de porta-enxertos por unidade de área, foram: 6(0,60m x 0,15m) x 1,20m e 2(0,50m x 0,15m) x 1,0m, com 62715 e 56960 porta-enxertos/ha em condições para receber os dois tipos de enxertia: verde e convencional. |

| ABSTRACT The objective of this study was to evaluate the performance of onion cultivars as a function of the spacing between plants. The experimental design was a complete randomized block in a 3 x 4 factorial scheme, with four replicates. The treatments were composed of the combination between three onion cultivars (Vale Ouro IPA 11, Serena and Rio das Antas) and four plant spacings (3, 6, 8 and 10 cm). The evaluated characteristics were total, marketable and unmarketable yield of bulbs, percentages of bulbs in classes 1, 2, 3 and 4, bulb mean weight, bulb dry weight. In onion cultivation, the cultivars Rio das Antas and Serena are the most indicated, with the highest marketable yields at 6 and 3 cm spacings between plants, respectively. The cultivar Vale... |

| ABSTRACT Production of interstocked seedlings of the ‘Pera’ orange can be achieved through inarching of a rootstock on nucellar seedlings, with the subsequent grafting of a new scion. By this process, the interstocked seedling can be obtained in less time, but production efficiency is low, and no data on quality standards are available. The aim of this study was to evaluate the quality, time and production efficiency of ‘Pera’ orange (PO) seedlings interstocked with two types of nucellar plantlet tissue, using the ‘Flying Dragon’ trifoliate as rootstock. The experimental design was of randomised blocks, with four treatments, six replications and ten plants per plot. For the technique employed, nucellar plantlets of the ‘Seleta’ orange (SO) or Rangpur Lime... |

| The study investigates the economic response of tart cherry yields to planting density using an unbalanced longitudinal yield data from tart cherry orchards in Northwest Michigan. The relationship between tart cherry yield and tree age is specified as a linear spline function and planting density interacts with tree age. A random effect method, treating block as random, is used to estimate the spline function. Stochastic simulation was used to estimate the mean and variance of the product of two random variables (price and yield), and the coefficient of variation was used as a measure of how much risk is involved in corn/soybeans production relative to tart cherries production. Estimates of the variance provided the discount factor (10%) and with yields... |

| O objetivo deste trabalho foi avaliar os efeitos da irrigação sobre as concentrações foliares de P e Zn e sobre a produtividade e o crescimento do cafeeiro (Coffea arabica), cultivado em plantio tradicional e adensado. Utilizou-se o delineamento experimental de blocos ao acaso, em arranjo de parcelas subdivididas, com quatro repetições. As parcelas corresponderam às densidades de plantio (3.333 e 10.000 plantas ha-1), e as subparcelas corresponderam às lâminas d'água, aplicadas por quatro manejos de irrigação: início da irrigação, quando a tensão d´água no solo à profundidade de 0,25 m atingia valores próximos a 20 ou 60 kPa; turno fixo de irrigação (três vezes por semana), de acordo com o balanço hídrico climatológico; e testemunha sem irrigação. Em 2009,... |

| Abstract The densification of orchards has become a viable alternative for producers seeking a greater use of current area, as well as greater profitability. In this sense, the spacing and training system to be used in the peach tree planting are extremely important to facilitate orchard management and, above all, to maximize tree yield. Based on this, the present research aimed to evaluate the possibility of orchard densification and the use of different numbers of main scaffolds to recommend the best way of training and spacing the ‘BRS Rubimel’ peach cultivar. The planting was carried out in 2010, in the city of Fraiburgo - SC, and eight treatments with different spacings between the plants in the rows and number of scaffolds were evaluated during four... |
