1. Production and fruit quality of watermelon hybrids under different plant spacing
RESUMO O manejo do espaçamento entre plantas na melancia altera a competição das plantas por água, luz e nutrientes, pois a população de plantas influencia a produtividade da cultura, a morfologia do fruto e a qualidade. O objetivo deste trabalho foi avaliar o manejo do espaçamento entre plantas de dois híbridos de melancia quanto à morfologia, prod

2. Hole spacing in soybean hill drop sowing1
ABSTRACT The aim of this study was to evaluate the development, yield and its components of soybean sown in hill drop method with variation in hole spacing, compared to the conventional sowing method in lines. The experiment was conducted in a randomized block design, with six treatments and four replications, using the variety M7739 RR IPRO with four plans

3. ACCURACY OF GENETIC PARAMETERS ESTIMATION AND PREDICTION OF GENOTYPIC VALUES IN EUCALYPTUS USING DIFFERENT PLOT TYPES
ABSTRACT A suitable experimental design should control the environmental effect and be capable of discriminating genotypes. Two clonal tests of Eucalyptus were planted side by side in a randomized block design with the same 32 treatments under two different plot designs. The first trial was designed with five plants per plot (linear plot, LP) and six block r

4. The management of orthotropic stems modulates the photosynthetic performance and biomass allocation of productive plants of Arabica coffee
ABSTRACT Due to the possibility of enhancing the physiological responses by modulating the architecture of coffee trees, the objective of the study was to analyze the leaf gas exchanges and biomass allocation of Arabica coffee cultivated with different numbers of orthotropic stems. The experiment was carried out in a plantation located in Santa Teresa-ES, Br

5. Amaranth in southernmost latitudes: plant density under irrigation in Patagonia, Argentina
ABSTRACT In Argentina there have been few evaluations of Andean pseudocereal plantings. This study explored the response of Amaranthus cruentus cv Mexicano to different plant densities under furrow irrigation in the lower valley of the river Negro, Patagonia, Argentina. The experimental design consisted of 3 blocks with randomized treatments (subplots), each

6. PLANT RICHNESS AND LIFE FORM DIVERSITY ALONG VEGETATION AND FOREST USE GRADIENTS IN NORTHWESTERN PATAGONIA OF ARGENTINA
ABSTRACT The imbalace between the increase in the demand and the decrease in the supply of products from natural forests, partly explains the on-going development of exotic tree plantations. In northwestern Patagonia of Argentina, Pinus ponderosa (Pinaceae) afforestation plays a key role in ameliorate degraded soils, but may also reduce biodiversity. The eco

7. Productivity, quality of fruits and architecture of Jalapeño pepper at different planting densities
RESUMO Mecanizar a colheita de pimenta Jalapeño exige adequação do sistema de produção. Espaçamentos entre plantas na linha (10 a 40 cm; 60 cm fixo entre linhas) foram avaliados quanto à arquitetura da planta, produtividade e qualidade de frutos da cultivar BRS Sarakura, durante três anos no delineamento blocos ao acaso, com cinco repetições. A pro

11. CHEMICAL CONTROL OF ASIAN SOYBEAN RUST AS A FUNCTION OF CULTIVAR, ROW SPACING AND SPRAY BAR SUPPORT SYSTEMS
ABSTRACT Product deposition and foliar surface cover are highly impacting factors on the efficiency of foliar fungicides applied to soybean cultivars, due to their low mobility, with side effects on Asian soybean rust (ASR) control. Spray bar support systems, such as the air curtain (Vortex®) and the use of nozzles along the bar (Dropleg®), stand out as an

12. Optimal planting density for cut Lilium and tuberose production
Abstract Lilium and tuberose are promising geophytic flowers, which have high market demand in global floral markets. A study was conducted to optimize planting densities for cut lilium and tuberose production. Bulbs of Asiatic lily ‘Brunello’ and tuberose ‘Single’ were planted on 7.5 cm, 15.0 cm and 22.5 cm between bulbs while ridge were spaced at 6
