| 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'... |

| A cultura do abacaxizeiro apresenta grande potencialidade de expansão no Acre, porém existem problemas relacionados ao manejo da cultura como espaçamentos inadequados, presença abundante de plantas espontâneas no pomar, sistema de plantio ineficiente e manejo de solo inapropriado que comprometem o rendimento a produção de frutos. Assim, o objetivo do estudo foi avaliar a influência de densidades de plantio e coberturas de solo no controle de plantas espontâneas e no crescimento, rendimento e qualidade físico-química de frutos de abacaxizeiro, cultivar BRS "RBO" - Rio Branco, em Rio Branco, AC. O experimento foi instalado e conduzido em área de produtor localizada na BR 364, Km 07, coordenadas geográficas 10º 00' 23" S, 67º 43' 05" W. O delineamento foi em... |

| 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. |

| The objective of this work was to evaluate the effect of nitrogen fertilization on the mineral composition of leaves, initial growth, and yield of peach (Prunus persica) tree advanced selections grown at a high-planting density. The experiment was carried out between 2012 and 2015 in a randomized complete block design, with a combination of advanced selections of the 'Cascata 1513' and 'Cascata 1067' peach trees and of N fertilization doses (0, 30, 60, and 120 kg ha-1 N). Green weight after pruning, diameter, and increase of trunk diameter, canopy volume, plant height, branch length, number of buds per centimeter of shoot, chlorophyll index, leaf area, rust incidence, average production, number of fruit, and mass of fruit were evaluated. Genotype affects... |

| O trabalho constou de um experimento com melao (Cucumis melo L.), conduzido em um Vertissolo, em Juazeiro, BA, em 1995, com o objetivo de avaliar o efeito de niveis de N por fertirrigacao e de densidades de plantio na produtividade e qualidade de fruto. Os niveis de N foram 0, 80, 130 e 180 kg/ha, conbinados com os espacamentos 2,00 e 1,80 m entre linhas e 0,20 m entre plantas, com uma ou duas plantas por cova. A fonte de N foi a ureia, aplicada diariamente ate 42 dias apos a germinacao, por meio da irrigacao por gotejamento. Todos os tratamentos receberam uma adubacao uniforme de 120 kg/ha de P2 O5 e 120 kg/ha de K2 O. Os espacamentos entre linhas nao causaram diferencas significativas em nenhuma variavel estudada. O nivel de 80 kg/ha de N combinado com... |

| 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... |

| Climate variations over the year and plant density tend to strongly affect the agronomic performance of carrot crops. Thus, the objective of this work was to evaluate the performance of the cultivar Brasilia in crops under mild (winter) and high (summer) temperatures. An experiment was conducted from May 2011 to February 2012, using a randomized block design and treatments arranged in split plot, with three replications. The plots consisted of planting seasons (winter and summer) and the subplots of plant spacing (4, 6, 8 and 10 cm). The height of plants presented a linear decrease, from 53.4 to 51.0 cm, with an increase in spacing in summer planting, while in winter the greatest height (50.7 cm) was obtained with spacing of 8.0 cm between plants. The... |

| 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... |
