1. Coverage plants in the management of skeletal coffee
ABSTRACT Currently, one of the most used practices in national coffee production is skeletal pruning, to preserve productive capacity, correct plant architecture, minimize the occurrence of diseases, among others. Also, it reduces the plants diameter, exposing the soil to climatic conditions, erosion, loss of moisture and nutrients, negatively affecting the

2. Broccoli in succession to pearl millet: nutrient cycling, production and soil chemical attributes
ABSTRACT For its production, broccoli requires large quantities of nutrients in relatively short periods. As a conservation technique, the no-tillage planting of broccoli over the pearl millet straw in succession may interfere with the dynamics of nutrient release, inflorescence production and the chemical attributes of the soil. The objectives of this work

3. Conservation system improves soil microbial quality and increases soybean yield in the Northeastern Cerrado
ABSTRACT The conservation tillage systems is based on the surface protection by crop residue and reduced soil disturbance. These two principles can favor the soil quality and promote sustainable agricultural systems. The study was developed with the objective of measure soil microbial biomass, soil basal respiration, enzymatic activity and soybean yield in c

4. Nondestructive analysis of photosynthetic pigments in forage radish and vetch
ABSTRACT Chlorophylls and carotenoids are the main photosynthetic pigments in plants, and photosynthetic potential can be used to determine the nitrogen fixation or cycling capacity of cover crops. Therefore, this study quantified and compared the content of photosynthetic pigments in Raphanus sativus and Vicia sativa by using two different methods, namely t

5. Tillage systems and cover plants change organic fractions of phosphorus in oxisol of eastern Amazonia
ABSTRACT Due to the large extent of degraded areas in the Amazon, the use of conservation systems is very important to contain the advance of the agricultural frontier, and may favor the availability of nutrients such as phosphorus (P). This study evaluated effect of tillage systems on and cover plants distribution of organic P fractions (Po) in oxisol under

6. Plastic soil covers in vegetative development, production and quality of strawberries
ABSTRACT The purpose this study was to evaluate the vegetative development, yield and quality of strawberry cultivars of short and neutral days as a function of soil cover. Two experiments were carried out in a protected environment. The experimental design used in both experiments consisted of randomized blocks, with subdivided plots. Harvests were carried

7. Integrated use of sewage sludge and basalt mine waste as soil substitute for environmental restoration
Abstract If not managed properly, mining waste can be detrimental to the environment. In addition, sewage treatment plants produce sludge, a biowaste rich in organic matter which is often sent to landfills. The present study evaluated the use of sewage sludge as an amendment for mine waste from a basalt quarry as an alternative to the use of soil from borrow

8. Fruit quality and occurrence of mildew in Niagara Rosada grown under plastic cover and defoliation rates
ABSTRACT The purpose of this study was to evaluate the agronomic behavior of the Niagara Rosada variety cultivated under plastic cover, using defoliation intensities, and its influence on the Plasmopara viticola. The experiment was conducted in Francisco Beltrão, PR, Brazil, in a vineyard of Niagara Rosada variety in a trellised system during the 2016/2017

9. 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

10. Growth dynamics of the branching system in grasses: an architecture-based methodology for quantitative evaluation applied to two genotypes of Paspalum vaginatum
Resumo Foi estudada a dinâmica do crescimento dos caules aéreos de Paspalum vaginatum, uma gramínea de ampla distribuição. Com o objetivo de identificar características diferenciais quantitativas entre dois genótipos, as plantas foram cultivadas ao ar livre em vasos durante dois verões consecutivos. Os eixos de diferentes ramificações foram marcado

11. Effect of canopy cover on development of cedar (Cedrela fissilis) and aspects of damage caused by Hypsipyla grandella in agroforestry system
Resumo Cedrela fissilis (Vell.) é uma importante espécie madeirável nativa da América do Sul que sofre frequente pressão do extrativismo ilegal. As iniciativas de cultivo comercial acumulam fracassos recorrentes pela ação da broca-do-cedro Hypsipyla grandella (Zeller, 1848). Um dos métodos de manejo utilizados para reduzir os ataques é o plantio em

12. Glyphosate as Growth Regulator for Bahiagrass and Broadleaf Carpetgrass
RESUMO: Objetivou-se neste trabalho avaliar o efeito do uso do herbicida glyphosate como regulador de crescimento em grama Batatais e São Carlos. Os experimentos foram conduzidos em casa de vegetação no delineamento inteiramente casualizado com dez doses de glyphosate: 0; 5,625; 11,25; 22,5; 45; 90; 180; 360; 720; e 1.440 g a.e. ha-1 e quatro repetições
