1. Nitrogen top-dressing fertilization of maize cultivated in single and twin-row systems
ABSTRACT The aim of this study was to evaluate the effects of cropping systems (single and twin-rows) and N fertilizer rates in the second top-dressing on the agronomic performance and relative economic returns of maize. The experiment was conducted in a randomized block design, with subplots and three repetitions. The plots were composed of two cropping sys

2. 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

4. Production and nutritive value of pastures in integrated livestock production systems: shading and management effects
ABSTRACT This study aimed to evaluate the production characteristics of pastures in integrated livestock production systems. For that, an experiment was carried out in São Carlos, SP, Brazil, from 2013 to 2015. Forage development, production and nutritive value were evaluated in five beef cattle production systems: extensive continuous stocking (Urochloa de

5. TIME AVAILABLE FOR SPRAYING AND MECHANIZED SOWING IN THE NORTHEAST OF THE STATE OF MATO GROSSO DO SUL AND SOUTH OF GOIÁS
ABSTRACT The sizing of mechanized agricultural systems depends on the soil and climatic conditions, the crop and the work regime. The aim of this study was to determine the probabilities of time available during an agricultural year for mechanized spraying and sowing in the northeast region of the State of Mato Grosso do Sul and south of Goiás. The meteorol

6. Physiological reorganization in the hypotrich ciliate Apoamphisiella vernalis (Protista, Ciliophora, Hypotricha)
ABSTRACT Physiological reorganization is described for the first time for the hypotrich ciliate genus Apoamphisiella Foissner, 1997, based on a population of A. vernalis (Stokes, 1887) Berger, 2006 collected from an eutrophic pond in the state of Minas Gerais, Brazil. Stomatogenesis is epiapokinetal, and the cirral pattern reorganizes from six typical fronto

7. Microclimate and soil moisture in a silvopastoral system in southeastern Brazil
In this study, the microclimate changes in silvopastoral systems are quantified at different time and spatial scales and compared with single-pasture systems. The study was conducted in a silvopastoral system in São Carlos, Brazil (22°01' South and 47°53' West). The silvopastoral system consisted of grass pastures [Urochloa (sin. Brachiaria) decumbens cv.

8. Manejo do mofo branco (Sclerotinia sclerotiorum L.) em tomateiro industrial / Management of white mold (Sclerotinia sclerotiorumL.) in tomato industry
Brazil ranks ninth in the world production of tomato (Solanum esculentum L.), while much of this production is destined for processing industries. The added value obtained with the fruit processing endorses this species as the vegetable with the greatest economic importance in the Cerrado region of Brazil, where the State of Goiás stands out as the largest

10. Parâmetros produtivos do consórcio sorgo-braquiaria brizantha e valor nutricional da silagem
We conducted this study in order to determine the effects of intercropping Sorghum bicolor and Brachiaria brizantha under the nutritional value of silage and analysis of production parameters related to this consortium. After 60 days and the fermentation stage of the material already completed, the silos were opened. The treatments were: Brachiaria singles i

11. Spatial arrangement and density effects on an annual cotton/cowpea/maize intercrop. I. Agronomic efficiency.
Field experiments were conducted in Tucson, Arizona, to examine the effects of spatial arrangement and density on the agronomic efficiency of an annual cotton/cowpea/maize intercrop. The major results were: (1) the Land Equivalent Ratio (LER) for yield was higher in the spatial arrangement of single rows of cowpea and maize between single rows of cotton, (2)

12. Influence of row spacing reduction on maize grain yield in regions with a short summer.
The interest in reducing maize row spacing in the short growing season regions of Brazil is increasing due to potential advantages such as higher radiation use efficiency. This experiment was conducted to evaluate the effect of row spacing reduction on grain yield of different maize cultivars planted at different dates. The trial was conducted in Lages, in t
