| The objective of this study was to evaluate the genotypic stability of agronomic traits in hybrids of Panicum maximum. Hybrids originating from the crosses between two sexual parents and cultivars Mombasa and Tanzania were evaluated in an incomplete-block design. Evaluated traits were total dry matter, leaf dry matter, stem dry matter, percentage of leaves, and leaf:stem ratio. These traits were evaluated in six harvests. Overall, higher repeatability was observed for the traits total dry matter and leaf dry matter, especially when harvests 4, 5, and 6, occurring in spring and summer, were evaluated. The leaf dry matter was the trait that provided the greatest repeatability and determination. The repeatability of stem dry matter, percentage of leaves, and... |

| Abstract Soil and water salinity are considered the main limiting factors of plant production. This work aimed to evaluate the influences of irrigation frequency and soil salinity on the development of cactus pear cv. Miúda (Nopalea cochenillifera Salm Dyck). The experiment was conducted in factorial arrangement of four salinity levels: 0.3 (control), 0.5 (low), 1.5 (medium) and 3.6 (high salinity) (ds m-1), associated with four irrigation frequencies (each 7, 14, 21 and 28 days) and two soil textures (sandy and sandy loam) in a randomized block design with four replicates. One cladode was planted in each polyethylene pot containing 10 kg of soil. The soil texture influenced some of the morphological characteristics of the cactus pear, so that plants grown... |

| 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. |

| This study aimed to evaluate in situ degradability and degradation kinetics of DM, NDF and ADF of silage, with or without tannin in the grains. Two isogenic lines of grain sorghum (CMS-XS 114 with tannin and CMS-XS 165 without tannin) and two sorghum hybrids (BR-700 dual purpose with tannin and BR-601 forage without tannin) were ensiled; dried and ground silage samples were placed in nylon bags and introduced through the fistulas. After incubation for 6, 12, 24, 48, 72 and 96 hours, bags were taken for subsequent analysis of fibrous fractions. The experimental design was completely randomized with 4 replicates and 4 treatments and means compared by Tukey’s test at 5% probability. As for the DM degradation rate, silage of CMSXS165without tannin was... |

| This research evaluated, using the in situ technique, the dry matter and fiber fraction degradability of the Mineirão stylo (Stylozanthes guianensis). The nylon bag method was used for the degradability assay, with two incubations in rumen-cannulated adult female cows. In each incubation, 25 samples of 7.0 g each were used. The samples were collected at 0, 6, 9, 12, 24, 36, 48, 72 and 96 hours. The experiment was conducted according to a randomized blocks design and data were submitted to analysis of variance. The maximum effective degradability was obtained in the 2% passage rate. For the 5% passage rate the Mineirão stylo showed effective degradation of 75.70% for dry matter, 59.01% for neutral detergent fiber and 76.81% for acid detergent fiber. The... |

| This work aimed to promote in vitro seed germination and disinfestation of the sweet cactus. Seeds were submerged in alcohol at 70% for 1 min. and then treated with sodium hypochlorite solution at different concentrations: 0.0; 0.5; 1.0 and 1.5%. After this treatment, the seeds were washed four times in distillated, deionized and autoclaved water. Seeds were inoculated in MS medium with different concentrations of sucrose (0.0, 2.5, 5.0, 7.5 and 10.0 g L-1). The experimental design was completely randomized in a factorial experiment 4 x 5, with five replicates for treatments. Contamination, germination and seedling growth were evaluated. The results of the analysis of variance indicate that there were no significant interactions among factors. There was no... |

| O presente trabalho foi conduzido, em area de "cordilheira", na parte central da sub-regiao dos Paiaguas, do Pantanal Mato-Grossense. Os solos sao formados por sedimentos arenosos aluviais e na maior parte sao de baixa fertilidade. Entre 1980 e 1985, foram introduzidas e avaliadas 51 gramineas e 105 leguminosas, com o objetivo de identificar forrageiras adaptaveis as condicoes ecologicas da regiao. Para cada cultivar e/ou especies foram utilizadas duas parcelas de 1,5 x 3,0m com adubo (CA) e sem adubo (SA). O rendimento de materia seca de CA foi superior ao de SA apenas no primeiro ano. Segundo o indice de avaliacao (IA), no dominio de 0 a 3, as forrageiras mais promissoras se encontraram nos generos Andropogon, Brachiaria e Calopogonium. Das gramineas, a... |
