Foram conduzidos dois experimentos em Coimbra, Estado de Minas Gerais, um no verão-outono e outro na primavera-verão com o objetivo de avaliar o efeito de diferentes doses de molibdênio e nitrogênio sobre o feijoeiro, cultivar Meia Noite, utilizando delineamento em blocos casualizados, com quatro repetições, e esquema fatorial 4 x 2 x 2, envolvendo quatro níveis de molibdênio (0, 40, 80 e 120 g há-1) aplicados em pulverização foliar aos 25 dias após a emergência das plantas, duas doses nitrogênio aplicadas na semeadura (0 e 20 kg há-1) e aplicadas duas doses de nitrogênio em cobertura (0 e 50 kg há-1). Tanto na presença como na ausência de nitrogênio na semeadura ou cobertura, o incremento da dose de molibdênio até 80 g há-1 eleva o número de vagens por... |

Abstract Zinc deficiency affects one third of the population and a possible solution is the agronomic biofortification of vegetables. Due to the increased consumption of arugula, this vegetable has good potential of use; however, there are few researches on the subject. The objective of this study was to evaluate the effect of foliar zinc applications, at different times, on physiological, yield, nutritional, and biofortification parameters of the ‘Broad Leaf’ arugula. Three doses (0.5, 1, and 1.5 kg ha-1 Zn) were evaluated at five times (15; 20; 25; 15 and 20; and 15, 20 and 25 days after emergence) and a control treatment. It was observed that there was no effect of the application on the physiological variables, as well as on the height, leaf area, and... |

Wheat is grown in Brazil, mostly in no-till, a system in which the zinc can become potentially deficient, due to excessive application of acidity corrective and phosphate fertilizers in surface and, or at shallow depths. This study aimed to evaluate the effect of foliar application of zinc in agronomic characteristics and yield of wheat. The experimental design was randomized blocks with five replications. Treatments consisted of four doses of zinc (0, 54, 108 and 216g ha-1 Zn), divided into two foliar applications, the first at tillering (18 days after plant emergence) and the second at the boot stage (65 days after emergence). Foliar application of zinc increased the number of fertile tillers and yield of wheat, however, have little effect on the... |

La presente investigación se llevó a cabo en condiciones de invernadero del Campus Montecillo, con rizomas de Alstroemeria cv. “Olga”, bajo sistema hidropónico, con la solución universal de Steiner hasta la cosecha. Consistió en dos etapas: fase de invernadero y vida de florero. En fase de invernadero se aplicaron tratamientos mediante fertilización foliar al cultivo bajo un diseño experimental completamente al azar con cinco repeticiones. Se evaluaron nueve dosis de fertilización obtenidas de un estudio previo. Las fuentes de fertilizantes utilizadas fueron: Ca(NO3)2, MgSO4- y FeEDTA. Las variables evaluadas fueron: clorofila, longitud de hoja, diámetro del tallo, número de hojas por tallo y longitud de tallos. La investigación en la fase de vida de... |

Abstract: The objective of this work was to evaluate the effect of magnesium foliar spray on yield performance of soybean (Glycine max) and corn (Zea mays) cultivated in soil with adequate levels of base saturation and magnesium content in Brazil. The field trials were conducted on a Typic Hapludox cultivated with soybean and corn in the 2013/2014 and 2014/2015 crop seasons, respectively. Treatments consisted of Mg rates (50, 100, 250, 500, 1,000 and 1,500 g ha-1 and a control without Mg) applied during the V4, R1, and R5.1 (soybean) or V4 and R2 (corn) phenological growth stages as magnesium sulfate heptahydrate (MgSO4∙7H2O). The SPAD index, leaf Mg content, grain yield, and 100-grain weight were evaluated. The Mg foliar spray increased the SPAD index in... |

Abstract: The objective of this work was to evaluate the effect of applying N sources to leaves and N rates to the soil on the growth, N uptake, and grain and crude protein yields of the common bean (Phaseolus vulgaris) crop. Three experiments - two irrigated and one rainfed - were conducted during the 2012/2013 agricultural season, in a randomized complete block design with four replicates. The treatments consisted of the application of: four N rates (0, 45, 90, and 180 kg ha-1) to the soil, as topdressing in the V4 stage; and five N sources/rates - i.e., control, without foliar N application; 2.5 kg ha-1 N as conventional urea (N-CU); 5.0 kg ha-1 N-CU; 2.5 kg ha-1 N as slow-release urea-formaldehyde (N-SR); and 5.0 kg ha-1 N-SR - to leaves, in the R5... |

The genotypic variability in molybdenum (Mo) accumulation in common bean seeds has been demonstrated in cases in which soil is the main Mo source, but this variability is yet unknown when Mo is foliar-applied. Therefore, seed Mo concentrations (SMoCc) and seed Mo contents (SMoCt) of 12 genotypes were determined in four experiments in the Zona da Mata, Minas Gerais, Brazil, in which plants were sprayed with 600 g ha-1 Mo. For comparison, two additional experiments without external Mo were conducted. Without Mo application, the average SMoCc was undetectable or 2.83 µg g-1, without significant differences among genotypes. On average, with Mo applications, SMoCc ranged from 14.7 to 25.0 µg g-1 and SMoCt, from 3.94 to 6.84 µg. 'Majestoso' was among the... |
