1. High-throughput phenotyping as an auxiliary tool in the selection of corn hybrids for agronomic traits
ABSTRACT High-throughput phenotyping (HTP) using vegetation indices (VIs) is an important data source for managing plant breeding programs and can be a promising tool in indirect selection. This study hypothesized that VIs are correlated with agronomic traits in corn, and therefore, HTP can be an auxiliary tool for selecting superior genotypes. The objective

2. Agronomic performance of soybeans with the presence of volunteer RR corn
ABSTRACT The presence of volunteer corn plants among soybeans, both resistant to glyphosate, has increased in recent years in Brazil. The objective of this study was to quantify the impact on the agronomic performance in RR soybeans by the presence of volunteer RR corn in field conditions. The experiment was conducted in Tiradentes do Sul (RS), 2018/19 harve

3. Interactions between green manure and rock phosphate on corn production in family farms
ABSTRACT The aim of this study was to analyze whether the use of green manures in association with rock phosphate rates can guarantee corn yields to family farmers. An experiment was conducted with six types of green manures: Mucuna cinereum, Crotalaria juncea, Crotalaria ochroleuca, Cajanus cajan, Pennisetum glaucum and a weedy fallow control treatment; and

4. Times and methods of black oat management on corn plantability
ABSTRACT The importance of maintaining straw on the soil surface is a subject widely discussed and proven in the literature. However, the effects of this straw on planting efficiency and quality still lack information. In this sense, both time and method of the black oat management influence the permanence of the straw on the soil and, thus, can interfere in

5. Nitrogen fertilization split in green corn under rainfed system
ABSTRACT The objective of this work was evaluating the nitrogen fertilization splitting on the performance of green corn, grown in rainfed system. The experiment was carried out in Forquilha, Ceará state. Two varieties of corn (Sweet and Gorutuba) were used in the experiment, grown in five types of nitrogen fertilization in the crop cycle (one; three; six;

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. Damage caused by Diceraeus (= Dichelops) melacanthus in maize plants subjected to combinations: bioinoculation and imidacloprid seed treatment
ABSTRACT The aim of this study was to evaluate the damages caused by Diceraeus (=Dichelops) melacanthus in maize plants subjected to bioinoculation with or without imidacloprid seed treatment. In this study, five different combinations of bioinoculants and imidacloprid seed treatment were applied to maize seeds in a completely randomized design. The bioinocu

8. Co-inoculation of Anabaena cylindrica and Azospirillum brasilense during initial growth and chloroplast pigments of corn
RESUMO Embora comprovados os efeitos isolados das cianobactérias Anabaena cylindrica bem como da bactéria Azospirillum brasilense, na fixação biológica de nitrogênio e na promoção de crescimento de plantas de milho, a co-inoculação de ambas pode ampliar outros benefícios às plantas. O objetivo foi avaliar o crescimento inicial e teores de pigment

9. Green and sweet corn grown under different cover crops and phases of the no-tillage system
RESUMO Os milhos especiais são cultivados o ano todo e de forma convencional, contudo, quando cultivados sob sistema de plantio direto (SPD) pode aumentar a produtividade das culturas. O objetivo deste estudo foi avaliar o desempenho agronômico do milho doce e verde cultivados sob resíduos de diferentes coberturas e estádios de implantação do SPD. Dois

10. Effect of two oral formulations of cannabidiol on responses to emotional stimuli in healthy human volunteers: pharmaceutical vehicle matters
Objective: To compare plasma concentrations of cannabidiol (CBD) following oral administration of two formulations of the drug (powder and dissolved in oil), and to evaluate the effects of these distinct formulations on responses to emotional stimuli in healthy human volunteers. Methods: In a randomized, double-blind, placebo-controlled, parallel-group desi

11. High-throughput phenotyping by RGB and multispectral imaging analysis of genotypes in sweet corn
RESUMO O milho doce (Zea mays subsp. saccharata) destina-se principalmente ao processamento industrial. Otimizar tempo e custos durante o melhoramento de plantas é fundamental. Uma alternativa é o uso de fenotipagem de alto rendimento (HTP) indiretamente associada a caracteres agronômicos e teores de clorofila. Este trabalho teve como objetivo (i) verific

12. Green manure with fabaceous species in monoculture or intercropped with corn in the organic cultivation of pumpkin in succession
RESUMO Objetivou-se avaliar em três ciclos consecutivos o desempenho fitotécnico de fabáceas herbáceas cultivadas em monocultivo ou consorciadas ao milho e a produtividade de abóbora em sucessão. O delineamento estatístico foi em blocos casualizados em arranjo fatorial 2 (monocultivo ou consórcio) x 3 (espécies fabáceas) + 1 (monocultivo de milho).
