1. COST OF AERIAL AND GROUND SPRAYINGS AND TECHNOLOGICAL REPLACEMENT POINT: A CASE STUDY IN THE REGION OF MINEIROS, GO, BRAZIL
ABSTRACT One of the main costs in agriculture is related to mechanized operations, which, in turn, are associated with the capital invested in machinery and equipment, the scale of production, and the operating efficiency. Thus, the choice of technology to carry out these operations must take these factors into account to minimize the production cost. In thi

2. Production and quality of the silage of corn intercropped with Paiaguas palisadegrass in different forage systems and maturity stages
ABSTRACT The objective of this study was to evaluate dry matter production, fermentative parameters, and nutritional value of the silage of corn intercropped with Paiaguas palisadegrass in different forage systems and maturity stages, in the off-season. The experiment was carried out in a randomized block design, with four replications, in a 5×3 factorial a

3. 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

4. Incidence of stalk rots in corn hybrids influenced by sowing time and nitrogen rates
ABSTRACT Stalk rots compromise the translocation of water and nutrients, affecting grain filling. This study aimed to quantify the incidence of stalk rots in corn hybrids depending on sowing time and nitrogen topdressing rate, and to assess any correlation with grain yield. The experiment was conducted under field conditions in Atalanta, Santa Catarina state

5. Yield losses in off-season corn crop due to stalk rot disease
Resumo: O objetivo deste trabalho foi avaliar as perdas causadas pelas podridões da base do colmo em híbridos de milho (Zea mays), bem como identificar os principais patógenos causadores da doença, durante a safrinha, no Estado do Tocantins, Brasil. Foram realizados dois ensaios, um com cinco híbridos, em 2015, e outro com quatro, em 2016. Espigas de pl

6. Relationship Among Crop Systems, Soil Cover, and Water Erosion on a Typic Hapludox
ABSTRACT Several soil conservation practices are used to reduce water erosion and ensure sustainable agriculture. An effective crop management practice is intercropping, in which two or more crops with different architectures and vegetative cycles are grown simultaneously in the same area. We hypothesized that intercropping of corn and jack-bean increases so

7. Urease Inhibitor and Irrigation Management to Mitigate Ammonia Volatilization from Urea in No-Till Corn
ABSTRACT High nitrogen (N) losses by ammonia (NH3) volatilization from urea can compromise nitrogen fertilization efficiency and corn yield. The purpose of this study was to assess the effects of irrigation management and the addition of the urease inhibitor N-(n-butyl)thiophosphoric triamide (NBPT) on NH3-N losses from urea and on corn yield. To this end, t

8. Banco de sementes e sistemas de renovação no pasto de capim-braquiária com integração de culturas agrícolas / Seed bank in renewal of pasture signal grass with crop livestock integration
The experiment was conducted to evaluate the renewal of pasture of Brachiaria decumbens with integration of crops in cropping systems "planting" direct and conventional. The experiment was conducted in pastures of Brachiaria decumbens Stapf. Located on the campus of University Federal of Viçosa, Viçosa, MG. The experiment consisted of five "systems" of gra

9. Monitoring fruit flies (Diptera, Tephritidae) in five municipalities of the state of Goiás Brazil / Monitoramento de moscas-das-frutas (Diptera, Tephritidae) em cinco municípios no estado de Goiás
Fruit flies (Diptera, Tephritidae) are important insect pests in world fruit orchards; responsible for significant yield losses, and an obstacle to the fruit market due to quarantine restrictions imposed by importing countries. The knowledge of their population dynamics in a specific region is an important factor in insect pest management programs. Fruit fli

10. Potenciais hospedeiros alternativos para o fitoplasma e o espiroplasma, agentes do enfezamento do milho, e alterações bioquímicas em plantas infectadas pelo espiroplasma / Potencial hosts for maize mollicutes, agent of corn stunt, and biochemical changes in plants infected by the spiroplasma
The maize bushy stunt and corn stunt are relevant diseases caused, respectively, by a phytoplasma and a spiroplasma (Spiroplasma kunkelii). Both kinds of stunting were reported in Brazil in the beginning of the 1970´s and became economically important in the beginning of the 1980´s, with the adoption of new techniques for maize cultivation. Although this p

11. Release of Trichogramma pretiosum (Hym.: Trichogrammatidae) and evaluation of Trichogrammatidae on egg masses of Spodoptera frugiperda (Lep.: Noctuidae) in corn / LIBERAÇÃO DE Trichogramma pretiosum (Hym.: Trichogrammatidae) E AVALIAÇÃO DE Trichogrammatidae EM POSTURAS DE Spodoptera frugiperda (Lep.: Noctuidae) NA CULTURA DO MILHO
Fall armyworm, Spodoptera frugiperda (J.E. Smith), is considered the major pest of corn. In general, the control of larvae is achieved with insecticides application, which can cause several environmental problems. In search of alternative control methods, egg parasitoids of the genus Trichogramma have been used in applied biological control programs, since t

12. Avaliação micológica e micotoxicológica de silagens destinadas à alimentação de bovinos de fazendas no Estado de São Paulo e Rio de Janeiro. / Mycological and mycotoxicology evaluation of silage intended to a food on cattle Farms in the State of São Paulo and Rio de Janeiro.
Despite having the second largest cattle herd in the world, the Brazilian has low rates of productivity. The performance of the animals in pastures is reasonable during the rainy season, being deficient in the dry season, caused by the low availability and quality of grass, which results in weight loss of animals. Thus ensiled foods are a recently solution t
