| This study aimed to characterize the harvest phenological stages of soybean cultivars intended for silage. Cultivars were evaluated for dry weight of the composite sample, branches, leaves and pods; wet mass of branches, leaves, pods and ground natural matter. This experiment was a 3 x 2 factorial randomized block design, with four replications each, where the first factor corresponds to the harvest stage: R4, R5 and R6; and the second factor refers to two soybean maturity groups (8.0 and 8.1). A significant interaction was detected only for ground natural matter. Higher values of most traits evaluated were observed for the R6 harvest phenological stage. The cultivar with maturity group 8.0 showed higher values for ground natural matter. |

| Alfalfa weevil (Hypera postica Gyllenhal.) control is traditionally based on the use of chemical insecticides. Due to the side effects of these compounds, there are many motivations for the use of integrated control methods, which may include the use of biopesticides (microbial and botanical). The result of the effect of seven doses of the tested biopesticides (500, 1000, 1500, 2000, 2500, 3000 and 3500 ppm) under laboratory conditions indicated that the insecticides Azadiractin® (1859.971 ppm) and Biobit® (2000.57 ppm) were of the highest, while Basiokara® (3178.697 ppm) and Naturalis® (2973.246 ppm) were of the lowest lethality. Field experiments were carried out based on randomized complete block design with 10 treatments and 4 replications. The... |

| ABSTRACT Brachiaria brizantha is a forage grass well adapted to tropical areas and cultivated in millions of hectares in Brazil. The apomictic mode of reproduction in this species, in addition to differences in ploidy between sexual and apomictic plants, impairs crossbreeding. The development of a methodology to transform apomictic cultivars will provide an option to introduce agronomic important traits to B. brizantha cv. Marandu. In addition, it will open the possibility to study in vivo the function of candidate genes involved in the apomictic reproduction. The objective of this work was to evaluate peeled seeds, isolated embryo from mature seeds, embryogenic calluses and embryogenic cell suspensions, as target explant for genetic transformation via... |
