Alterações morfoanatômicas foliares da cana-de-açúcar na fase de estabelecimento em condições de matocompetição

Aiming at the assessment of the production parameters and leaf tissues morph anatomical possible changes of the sugar cane RB 86 7515 variety in its establishment phase in the conditions of weed competition, a study over vases has been accomplished in the city of Dracena, São Paulo State, from April to June, 2010, at Universidade Estadual Paulista Júlio de Mesquita Filho. The species Brachiaria brizantha e Brachiaria decumbens, which are regarded as invaders, were used. It was also used the Completely Randomized Design with seven treatments and five repetitions, totalizing 35 lots or vases. The treatments ranged according to the number of Brachiaria brizantha and Brachiaria decumbens seeds, as it follows: T1 - no occurrence of weed competition; T2 - low occurrence of weed competition with Brachiaria brizantha; T3 - medium occurrence of weed competition with Brachiaria brizantha; T4 - high occurrence of weed competition with Brachiaria brizantha; T5 - low occurrence of weed competition with Brachiaria decumbens; T6 - medium occurrence of weed competition with Brachiaria decumbens, and T7 - high occurrence of weed competition with Brachiaria decumbens. There was an evaluation over the following issues after 60 days of the sugar cane plantation and the invading plants: the weight of the total dry matter of the plants, the thickness of the upper surface epidermis or adaxial, the thickness of the lower surface or abaxial, the thickness of the mesophill, the thickness of the limbo, the diameter of the xylematic vessels and the diameter of the phloem vessels. The weed competition of the species Brachiaria brizantha e Brachiaria decumbens, which are considered as invaders, provoked some reduction of the morph anatomical characteristics and of the sugar cane production. In general, the Brachiaria decumbens was the species which mostly influenced the leaf thickness of the sugar cane in negative aspects.

Load transportation in brazilian territory is made difficult by a deficient highway network, result of low maintenance and lack of government supervision. The problem aggravates when we consider the transportation of indivisible loads, mainly because the brazilian highways are not prepared for such task and few companies in Brazil have the necessary equipment suited for this kind of transport. In this dissertation it will be shown the analysis of a specific equipment to transport overweight indivisible loads, called hydraulic modular multi axle trailer. From an existing project (RB.04LE-01), manufactured and homologated in Brazil, it has been studied how the components in this trailer work so it could have been possible to elaborate a new model (RB.04LE-02), with two main objectives: reduction of costs and weight with subsequent increase in the liquid load for roadway transportation. The trailer’s components analyses were made utilizing the theory of fatigue strength of materials and finite element method with the von Misses criteria for a more safety when realizing the calculations

Agronomic and chemical characteristics of hybrid corn to ensiling

Our aim was to evaluate agronomic and chemical characteristics of corn hybrids to ensiling. It were evaluated nine corn hybrids (MX 300, RB 9308, 2B655, XB 6012, GNZ 2500, PL6890, PRE 32D10, PRE 22T10 e AG 1051), with three replicates. The higher fresh matter yield were observed in the hybrids PL6890 and PRE 32D10, while the dry matter yield was observed in the hybrid PRE 32D10 (13.43 t ha(-1)). The hybrids PRE 32D10 and PRE 22T10 stood out to present higher percent of leaf in relation to whole plant, while the lower percent of stems was found in the hybrids MX 300, 2B655 and XB 6012, however the higher leaves: stems relation was found in XB 6012 (0.49). There was higher CP content in the hybrid PRE 32D10 (9.10% of DM), while the lower NDF (57.78% of DM) and cellulose content (24.27% of DM) were observed in the hybrid GNZ 2500. The hybrid PL6890 presented higher ADF and lignin contents, the others hybrids had values lower. The lower NDIN content was observed in the hybrid RB 9308, while the lower AIDN content occurred on the hybrid 2B655. The lower buffer capacity was observed in the hybrid 2B655 (0.29). There are some differences on chemical composition among the corn hybrids used in this study, however, it is recommended to use the hybrids MX 300, PL6890 and PRE 32D10 for showing higher dry matter yield, which may reflect in the amortization of silage production costs.
