1. Data processing within rows for sugarcane yield mapping
ABSTRACT: The mapping of sugarcane yield is still not as widely available as it is for grain crops. Sugarcane harvesters cut and process the cane in a single or maximum of two rows, facilitating the monitoring of cane yield and its behavior on a small scale. This study tested a method for sugarcane yield data cleaning, investigating if the data recording fre

2. CARACTERÍSTICAS ESTRUTURAIS E PRODUTIVAS EM HÍBRIDOS INTRAESPECÍFICOS E INTERESPECÍFICOS DE CAPIM-ELEFANTE
Resumo Objetivou-se avaliar a estrutura e a produção de forragem em híbridos de capim-elefante manejados sob corte. Utilizaram-se como tratamentos 24 clones de capim-elefante provenientes da Embrapa Gado de Leite e o Cameroom como testemunha. Os capins foram cortados rentes ao solo, a cada 60 dias. Os parâmetros avaliados foram: produção e teor de mat�

3. Nitrogen supply to arugula from pig slurry composts in contrasting soils
RESUMO O estudo foi desenvolvido para avaliar o fornecimento de nitrogênio (N) à rúcula através de compostos obtidos por compostagem automatizada de dejetos líquidos de suínos (DLS). Durante a compostagem, xisto retortado (XR) e dicianodiamida (DCD) foram adicionados aos DLS para mitigar as perdas gasosas de N. O estudo foi realizado em casa de vegeta�

5. Purified glycerin in balanced diets of broiler chickens treated from 1 to 42 days of age
ABSTRACT We evaluated the technical feasibility of purified glycerin inclusion in balanced diets of broiler chickens treated from 1 to 42 days of age. A total of 240 broiler chickens were distributed in a completely randomized design into four treatments (0, 2, 4, and 6% purified glycerin inclusion), with six replicates of 10 broilers each. We evaluated prod

6. Increased metabolisable energy from glycerine or soybean oil in broilers
RESUMO Avaliou-se o efeito dos níveis de energia metabolizável incrementados com glicerina ou óleo de soja sobre o desempenho de frangos de corte em quatro fases (1 a 7; 8 a 21; 22 a 33 e 34 a 42 dias), e o rendimento de carcaça e cortes. Foram utilizadas 2400 aves com delineamento inteiramente casualizado, em esquema fatorial (duas fontes x quatro níve

7. Investigation of the Roof Presplitting and Rock Mass Filling Approach on Controlling Large Deformations and Coal Bumps in Deep High-Stress Roadways
Abstract Roadway deformation and coal bumps are major challenges for underground engineering. Taking the Lu'an mining district in Shanxi Province as an example, the failure mechanism of deep high-stress roadway was studied. Numerical simulations and the similar material test were performed to investigate the effect of the roof presplitting and rock mass fill

8. Seed size affects productive parameters in Sudan grass
RESUMO: O emprego de sementes maiores pode melhorar o desenvolvimento inicial, o estande de plantas e a produtividade de massa em cultivos forrageiros. Este trabalho visou avaliar o efeito do tamanho da semente de capim sudão (Sorghum sudanense L.), padronizada quanto à densidade, sobre parâmetros da qualidade fisiológica e de produtividade da cultura.

9. Volume equations for Khaya ivorensis A. Chev. plantations in Brazil
Abstract African mahogany (Khaya spp.) plantations are in expansion in Brazil and in the world. This fact justifies the need for studies related to its growth and yield. This paper aimed to evaluate the performance of single-entry and double-entry models for estimating merchantable and total volume for Khaya ivorensis plantations before the first thinning (7

10. Live Performance, Carcass, and Bone Quality Responses of Grower and Finisher Broilers to Dietary Metabolizable Energy Levels
ABSTRACT Broiler energy nutrition has attracted attention due to its economic importance, particularly during the rearing period of 22-42 days of age. There are many evidences that broilers changed their feed intake capacity due to genetic selection, especially when good quality pellets are fed, which suggests that modern broiler strains may achieve good per

11. Glutamine supplementation plans for broilers reared in high-temperature environments
ABSTRACT The purpose of this study was to evaluate the effect of glutamine supplementation plans on performance, carcass yield, and cut yield of broilers reared in a high-temperature environment. A fully randomized design was adopted for the experiment, comprising 900 male Hubbard broiler chicks assigned to five treatment groups (0% glutamine from one to 42

12. Growth Performance, Carcass Characteristics and Meat Quality of Griller-Type Broilers of Four Genetic Lines
ABSTRACT Griller-type chickens are broilers slaughtered between27and 29 days old weighing 1.3 to 1.5 kg and sold as a whole carcasses. The aim of the present study was to evaluate the growth performance, carcass traits, and meat quality of female broilers of four genetic lines reared for the production of griller-type chickens. A total of 960 broiler chicks
