1. Intercropping of collard green and radish ‘Cometo’: spatial arrangement and growing efficiency
ABSTRACT Intercropping is a method of growing plants that assists in rational use of natural resources. Based on this concept, the aim of this study was to evaluate the response of collard green and radish ‘Cometo’ crops in monoculture and in intercropping under different spatial arrangements through physical production indicators (technical coefficients

2. GROWTH, YIELD AND ECONOMIC ANALYSIS OF AN EUCALYPT-SOYBEAN CONSORTIUM: EFFECT OF THE DISTANCE BETWEEN TREES WITHIN THE ROW1
RESUMO Os sistemas agroflorestais (SAF) devem beneficiar todos os componentes do consórcio. O objetivo deste trabalho foi avaliar o efeito da distância entre plantas na linha de plantio sobre o crescimento e a produção do componente arbóreo e da cultura agrícola e, sobre a viabilidade econômica do consórcio. Para isso plantou-se clone de eucalipto no

3. Sampling Alternatives for Eucalyptus Trees in Integrated Crop-Livestock-Forest System
ABSTRACT The aim of this paper was to compare methods and sampling procedures applied to eucalyptus grown under different spatial arrangements in an integrated crop-livestock-forest system (ICLF). The study was carried out in Sinop county, Mato Grosso state, Brazil. Arrangements combining fixed and variable area methods to simple random and systematic sampli

5. Benchmark: Biomass Production in Eucalyptus Plantations as a Consequence of Fertilization
ABSTRACT The objective of this work was to evaluate the effects of fertilization, spatial arrangement and age on the biomass production in eucalyptus. The experiment was set up in a randomized block design with four replicates. Overall, 15 fertilizations adopted by forest companies in plots were evaluated, and two arrangements, 3.0 x 3.0 m and 6.0 x 1.5 m,

6. Plant spatial arrangement affects grain production from branches and stem of soybean cultivars
ABSTRACT Phenotypic plasticity is the ability of plants to undergo changes in morphology and yield components to adapt themselves to distinct environmental conditions. The knowledge on the changes in yield components of branches and stems at varied plant spatial arrangements needs to be updated due to recent changes in soybean production system. Thus, this s

7. Optimum plot size of planting and bio-agroeconomic revenues from arugula-carrot intercropping systems in a semi-arid region
Abstract The production of vegetable crops has been characterized as a highly intensive activity in the use of soil, water, inputs and labor in semi-arid regions, being practiced mostly by small family farmers as a way of subsistence, or in the small-scale commercialization of surplus production. Among the agricultural practices that have been successfully u

8. SPATIAL VARIABILITY OF THE WATER DEPTH APPLIED BY FIXED SPRINKLER IRRIGATION SYSTEMS
Abstract The uniformity of water application is an important factor in the evaluation of sprinkler irrigation systems. This uniformity depends on the type of sprinkler and its operating conditions, such as the arrangement and spacing between the sprinklers in the area; velocity and wind direction during the period of water application and the pressure variat

9. Spatio-temporal reconciliation to lessen losses in yield and quality of forage soybean (Glycine max L.) in soybean-sorghum intercropping systems
ABSTRACT Soybean suffers a serious blow to forage yield and quality while in intercropping with cereal forages like sorghum. The aim of this field investigation was to optimize planting time and spatial arrangement for boosting yield, quality and profitability of intercropped soybean. Treatments included soybean sown 20 days before and after sorghum under di

10. Nondestructive characterization of epoxy matrix composites reinforced with Luffa lignocellulosic fibers
ABSTRACT Luffa Cylindrica is a tropical plant from the Cucurbitaceae family, whose fruit becomes very fibrous when fully ripened. The lignocellulosic sponges of Luffa can be suitable for use as reinforcement of epoxy matrix composites, because they have a morphology with spatial 3-D arrangement as well as are eco-friendly materials (biodegradable, and high a

11. Improvement of Circularly Polarized Slot-Patch Antenna Parameters by Using Electromagnetic Band Gap Structures
Abstract This paper is devoted to the design of a novel Electromagnetic Band Gap (EBG) circularly polarized slot-patch antenna in multilayered configuration. The operating frequency band can be controlled via the disk radius and adjusting the slit lengths. An arrangement combining the circular slot-patch antenna design and feeding sources included are consid
