1. Linear relationships between biometric variables in lettuce seedlings
ABSTRACT Seedling production is an important step in growing vegetables. The study of relationships between variables has applications in practically all areas of study and is useful in identifying relationships among quality variables in vegetable seedlings. Thus, this work aims to estimate linear relationships between biometric variables in lettuce seedlin

2. 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

3. Agronomic trait selection and pre-germinative treatments in passion fruit hybrid
ABSTRACT Seed biometry and dormancy overcoming methods should be considered in the passion fruit production chain, in the seedling production stage, because of the different characteristics that condition the seedlings. The objective of this work was to identify and correlate the main biometric characteristics between seeds and seedlings and to select the be

4. Quality of sunflower seeds in function of thickness classification and sowing under speed variation of the seeder-fertilizer
ABSTRACT The objective was to evaluate the quality of sunflower seeds classified according to their thickness and passed through the seeder-fertilizer dosing system under variation of the travel speed. A lot of M734 was classified by thickness passing the seeds through a set of oblong-hole sieves and two thicknesses were selected. A portion of the seeds with

5. Tolerance of cerrado baru tree (Dipteryx alata) submitted to different doses of glyphosate
ABSTRACT Baru tree (Dipteryx alata Vogel.) is a been an alternative to establish an Integration Crop-Livestock-Forestry Systems (ICLFS), combining native species preservation with sustainable food production. However, the management procedure of herbicides for weed control is one of the major limiting factors to include tree components within ICLFS. Thus, th

6. SEMINIFEROUS PROPAGATION OF Cordia oncocalyx (Allemão) Baill. AND BIOMETRIC CHARACTERIZATION OF DIASPORES AND SEEDS
RESUMO Cordia oncocalyx Allemão Baill., conhecida popularmente como pau-branco, é uma espécie nativa da caatinga, com potencial socioeconômico e ambiental, entretanto, são escassos estudos silviculturais sobre a espécie. Portanto, objetivou-se analisar no presente trabalho as características biométricas dos diásporos e sementes por meio da biometria

7. INFLUENCE OF THE DENSITY AND DISTANCE OF Digitaria horizontalis Willd IN THE BIOMETRIC AND NUTRITIONAL PARAMETERS OF PRE-SPROUTED SEEDLINGS OF SUGARCANE
RESUMO A cana-de-açúcar é uma das culturas agrícolas mais importantes no Brasil e a presença de plantas daninhas nas áreas de produção podem interferir no crescimento, desenvolvimento e acúmulo de nutrientes da cultura, podendo estar relacionado à densidade e área de influência que a comunidade infestante se encontra na lavoura. Neste sentido, o

8. Growth and accumulation of nutrients in papaya tree seedlings grown on organic substrates
ABSTRACT The use of organic waste for the production of plant substrates is an important environmental and economic alternative. In this perspective, we performed a work in a greenhouse, with the aim of evaluating the effect of substrates from organic waste during growth, gas exchange and accumulation of mineral elements in ‘Sunrise Solo’ papaya tree see

9. FUZZY MODELING OF THE EFFECTS OF DIFFERENT IRRIGATION DEPTH IN RADISH CROP. PART II: BIOMETRIC VARIABLES ANALYSIS
ABSTRACT In order to estimate the response of biometric variables in different irrigation depths in radish crop, as well as their relations in the development of the crop, a fuzzy mathematical analysis was carried out from irrigation with depths of different percentages of the crop evapotranspiration (ETc), using Gaussian pertinence functions for the input v

10. FUZZY MODELING IN ORANGE PRODUCTION UNDER DIFFERENT DOSES OF SEWAGE SLUDGE AND WASTEWATER
ABSTRACT The present work aimed to develop mathematical fuzzy models to evaluate the effects of different doses of sewage sludge and irrigation with wastewater and potable water. Such models were elaborated from an experiment carried out at the Faculty of Agronomic Sciences, in the Department of Soil and Environmental Resources, from the Sao Paulo State Univ

11. Elevated leptin levels in healthy climacteric women from Northeastern Brazil: an effect of age or adiposity?
ABSTRACT Objective Climacterium is associated with elevated leptin levels and increased risk of cardiovascular disorders. Conflicting data diverge on whether high leptin levels in climacterium reflect increasing adipose mass or, at least partially, age-related hormonal changes. This study addresses this issue in women from a Brazilian state with a low huma

12. Correlação de parâmetros biométricos e produtivos em colônias deMelipona scutelaris
ABSTRACT The objective of this research was to estimate the correlations between the biometric and reproductive parameters of Melipona scutelaris. Four collections were performed with 30-day intervals, consisting of the evaluation of each colony, considering the following parameters: honey pot size and volume (HPS and VHP), estimated honey production (EHP),
