1. Productive potential and castor bean selection of the FCA-PB cultivar progenies
ABSTRACT Castor bean is a very important crop, however, in Brazil it still has relatively low productivity, 0.47 Mg ha-1 as a mean. Besides that the Country has significant castor oil demand and depends on international commerce to complement its production. The solution of these problems goes through the development of genotypes highly productive and adapte

3. Weed-removal system based on artificial vision and movement planning by A* and RRT techniques
ABSTRACT. The recent exploration of autonomous robotics tasks in agro-industry has permitted the integration of theories of artificial vision and mobile robotics with tasks in precision agriculture. Artificial vision allows for the classification of weeds and crops from images of plantations. With 3D-image processing systems, the location of the weeds is det

4. Phosphate Sources and Filter Cake Amendment Affecting Sugarcane Yield and Soil Phosphorus Fractions
ABSTRACT: The use of mineral phosphate fertilizers associated with organic residues can improve fertilizer use efficiency and consequently decrease their usage costs. Soil application of filter cake (FC) can provide nutrients and enhance physical quality. This study aimed to evaluate the effects of different phosphate fertilizers [rock phosphate (RP) and tri

5. Sampling Position under No-Tillage System Affects the Results of Soil Physical Properties
ABSTRACT Understanding the spatial behavior of soil physical properties under no-tillage system (NT) is required for the adoption and maintenance of a sustainable soil management system. The aims of this study were to quantify soil bulk density (BD), porosity in the soil macropore domain (PORp) and in the soil matrix domain (PORm), air capacity in the soil m

6. Four-way data analysis within the linear mixed modelling framework
Cultivars have to be evaluated under different crop management systems across agro-ecosystems and years using multi-environment trials (MET) before releasing them to the market. Frequently, data collected in METs are arranged according to cultivar (G), management (M), location, (L) and year (Y) combinations in a four-way G x M x L x Y data table that is high

7. Production technology and quality of corn silage for feeding dairy cattle in Southern Brazil
ABSTRACTThe objective of this study was to evaluate the production practices and use of corn silage in dairy farms in Southern Brazil, and to evaluate their impact on the nutritional quality and occurrence of mycotoxins. The data were collected by application of questionnaires among the producers, and by analysis of silage samples. The variables were subject

8. Influence of agro-ecological production areas on antioxidant activity, reducing sugar content, and selected phytonutrients of orange-fleshed sweet potato cultivars
Sweet potato is an important staple, and it is mainly known for its contribution of β-carotene in human diet. The effects of cultivar and habitat on this pigment and other nutritional characteristics of the crop still require investigation. In this study, three locally bred cultivars of sweet potato, two of which are orange-fleshed, were grown in three diff

9. Network modelling of palm biodiesel plants to supply the isolated electric power systems of Pará state
Despite the great advance brought by the National Interconnected System (NIS), which is able to provide clean hydroelectric power to almost all Brazilian customers, there are still cities supplied by power generated from fossil fuel, which are subsidized by taxes, they are called Isolated Electric Power Systems (IEPS). Pará State, that has 34 cities with IE

10. Effects of genetics and environment on isoflavone content of soybean from different regions of Brazil.
The effects of genetics and environmental factors on isoflavone content of soybean (Glycine max L.) cultivars grown in different locations in Brazil in 1993/94 were evaluated. Seeds of different cultivars were analised by high performance liquid chromatography (HPLC). In Rio Grande do Sul (RS), Parana (PR), and Mato Grosso do Sul (MS) States, a significant d

11. Investigação da microbiota endofítica onipresente em microplantas "axênicas / Investigation of ubiquitous endophytic microbiota in "axenic" microplants.
Tissue culture has been an important tool widely used for various purposes, among them the micropropagation has been highlighted due to the rapid production of healthy seedlings in a small space. Within this context, the term axenic plant has been distributed as an ideal to be achieved in this technique, which the search based on numerous methods that effect

12. Biological control of Aphis gossypii Glover (Hemiptera: Aphididae) in protected crop of cucumber using Marigold (Tagetes erecta L.) / Controle BiolÃgico do pulgÃo Aphis gossypii Glover (Hemiptera: Aphidae) em cultivo protegido de pepino com cravo-de-defunto (Tageres erecta L.)
Protected crop is a used practice in Brazil and abroad. Some characteristics like stable climate, high temperature and availability of food, favor the occurrence of pests on these systems, among them the Aphis gossypii. These insects are usually controlled chemically, which when applied in closed systems have little dispersion, thereby increasing its concent
