1. Phonolite associated with organic compound and potassium solubilizing bacteria in tomato cultivation
ABSTRACT The use of rock dust in Brazil has been studied and encouraged to reduce the Brazilian dependence on the foreign market for chemical fertilizers and as an alternative to organic agriculture. The objective of this research was to evaluate the effects of using phonolite rock powder and organic compound, associated with inoculation with the potassium s

2. Viability of Italian ryegrass (Lolium multiflorum) seeds under application of synthetic auxin herbicides
ABSTRACT Italian ryegrass (Lolium multiflorum) is one of the main weeds in the wheat crop, and the application of synthetic auxin herbicides has the potential to reduce seed viability, therefore, restricting the input into the seed bank. The objective was to evaluate the effects of synthetic auxin herbicides applied at different growth stages on germination,

3. FUZZY MODELING OF SALINITY EFFECTS ON RADISH YIELD UNDER REUSE WATER IRRIGATION
ABSTRACT The increase of water usage for food production in recent years has triggered researches on ways to optimize the use of water and to reuse saline water. The present study analyzes the effects of reused saline water in the irrigation of radish culture and the construction of a fuzzy logical mathematic model so that producers may evaluate their produc

4. Agronomic biofortification with iodine in lettuce plants cultivated in floating hydroponic system
ABSTRACT Iodine is essential to human metabolism, being fundamental in the production of the thyroid hormones. The consumption of biofortified foods can contribute to the increase of its intake. The objective of this study was to increase the iodine concentration in lettuce, also evaluating its effects on plant growth and production. The experiment was condu

5. FUZZY MODELING OF SALINITY EFFECTS ON PUMPKIN (Cucurbita pepo) DEVELOPMENT
ABSTRACT The low quality of the water currently used for irrigation purposes harms the quality of the products and can lead to a reduction in production. Thus, the objective of this work was to verify the effect of saline water in irrigation water, on biometric variables of pumpkin crop using a system based on fuzzy rules. The agronomic experimental part of

6. Biochar and swine wastewater: Effects on soil fertility of different textures and corn nutrition
ABSTRACT The use of organic waste in agriculture has stimulated the search for technologies that reduce environmental pollution. Among the residues are the biochar and swine wastewater (SW), which incorrectly disposed cause negative impacts, however, when combined, they can enhance agricultural production, due to the synergism between both. In this sense, th

7. Effects of sintering temperature on microstructure and properties of sanitaryware ceramic produced with waste material
Abstract This paper aims at exploring the possibility of using a great percentage of recycled materials into vitreous china (VC), thus, contributing to urban waste decrease while lowering the industry’s buying costs, previously optimized, for the sanitaryware production. The recycled blend was introduced in the ceramic slip, Sanitser VC, and used in three

8. Resistance to witches’ broom in adult plants and progeny of local varieties of cacao in Southern Bahia
ABSTRACT Plants of local cacao variety from Southern Bahia were evaluated in order to verify if there are different levels of resistance to witches’ broom disease in the study population and if the evaluation of adult plants in the field is a good predictor of these resistance levels. The seedlings were maintained under greenhouse conditions and inoculated

9. The production of ornamental pineapple in pots under different drip-irrigation depths
ABSTRACT The objective of this work was to evaluate the effects of irrigation depth on the commercial production of ornamental pineapple in pots. The experiment was carried out in a greenhouse located in Fortaleza, in the state of Ceará, Brazil. The experimental design was completely randomised, with five treatments and four replications. The treatments wer

10. The effects of two abundant ant species on soil nutrients and seedling recruitment in Brazilian Atlantic Forest
ABSTRACT Ants can influence soil fertility and the spatial distribution of seeds, with possible effects on seedling recruitment. The ant species Pachycondyla striata Fr. Smith, 1858 and Odontomachus chelifer (Latreille, 1802) co-occur in many forest areas in the Neotropics. We assessed soil fertility and seed bank structure in soil samples close and distant

12. Physiological responses of Eucalyptus urophylla young plants treated with biostimulant under water deficit
Resumo Os bioestimulantes consistem em uma mistura de reguladores de crescimento que, quando aplicados nas plantas, atuam no equilíbrio hormonal, melhorando seu desenvolvimento. Stimulate® é um bioestimulante composto por ácido indolbutírico (0,005%), cinetina (0,009%) e ácido giberélico (0,005%), que promove o crescimento das raízes, melhora a absor
