2. 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

3. Resistance of maize landraces from Brazil to fall armyworm (Lepidoptera: Noctuidae) in the winter and summer seasons
ABSTRACT The fall armyworm (Spodoptera frugiperda) is a major maize (Zea mays L.) pest in Brazil, whose larvae cause losses from plant emergence to harvesting stage. This pest has been controlled almost exclusively with chemical insecticides and Bt plants (transgenics); however, resistance evolution has been detected to these two control tactics. Therefore,

4. Influência da época de semeadura na severidade de doenças foliares e na produtividade do milho safrinha
RESUMO Nas principais áreas produtoras de grãos, o milho tem sido cultivado em duas safras, sendo o milho verão (primeira safra) e o milho safrinha (segunda safra). Desta maneira com a cultura do milho o ano todo no campo, criou-se uma ponte verde, favorecendo o desenvolvimento e a permanência de pragas e doenças. A severidade de doenças podem limitar

5. Evaluation of baroclinic effects on mean water levels in Guanabara Bay
RESUMO Este trabalho analisa aspectos hidrodinâmicos do sistema estuarino da Baía de Guanabara, localizado na costa sul do estado do Rio de Janeiro, Brasil. Padrões de circulação hidrodinâmica foram caracterizados, com e sem influência de gradientes de pressão baroclínicos devido a diferenças de densidade da água, para cenários típicos de verão

6. LEAF TEMPERATURE AND TRANSPIRATION OF PEQUI TREES WITH AND WITHOUT WATER RESTRICTION
ABSTRACT The answers to when and how much to irrigate orchards can be obtained based on the measurements of plants' transpiration and leaf temperature. This study aims to determine the leaf temperature and sap flow of the pequi tree (Caryocar brasiliense Camb.), both with and without water restriction. Further, the leaf temperature was measured by infrared t

7. Relationship between seasons and pregnancy rates during intrauterine insemination. A historical cohort
ABSTRACT BACKGROUND: The underlying cause of seasonal infertility in humans is unclear, but is likely to be multifactorial. OBJECTIVE: The aim of our study was to compare the pregnancy rates among infertile women who underwent induced ovulation and intrauterine insemination (IUI) with the season in which the fertility treatment was performed. DESIGN AND

8. Seasonal Variation of Plant Mineral Nutrition in Fruit Trees
Abstract This research evaluated the monthly variation of plant mineral nutrition in six species of fruit trees over a year. Leaf samples were taken from the fruit trees and nutritional status (N, P, K, Ca, Mg, Fe, Zn, Cu, Mn, and Mo) was determined in the leaves in a month basis from April until November for apple, persimmon and peach. Mandarin mineral nutr

9. Methods and rates of poultry litter fertilization for corn silage in organic system
ABSTRACT. The creation of proper soil fertility is fundamental to the agroecological transition phase and guarantees the sustainability of organic agribusiness. In a randomized complete block design with a 3 x 2 factorial scheme with 1 additional treatment (control, without organic fertilizer), we tested three poultry litter rates (7, 14, and 21 Mg ha-1) at

10. Response of duck breeders to dietary L-Carnitine supplementation during summer season
Abstract: A total number of 300 (225 ducks and 75 drakes) Sudani ducks, 28-wk-old were divided into five groups to investigate the effects of dietary L-carnitine (LC) supplementation on productive, hatching and physiological performance as well as nutrients digestibility coefficients. The results indicated that the productive performance and Semen quality pa

12. Sowing date and fungicide application in the agronomic performance of oleaginous brassica for the biodiesel production
ABSTRACT This work aims to evaluate the agronomic performance of crambe and juncea canola, sowed in the summer and winter season intervals with and without fungicide application. The cultivars used were FMS Brilhante and Terola 25A85 for crambe and juncea canola, respectively. The experimental design was randomized blocks in split plots, in which the plots w
