Alterações em Variáveis Agrometeorológicas pelo Uso de Estufa Plástica

O presente trabalho teve como objetivo verificar o efeito da cobertura plástica de polietileno de baixa densidade (PEBD) sobre a temperatura do ar, umidade relativa do ar, déficit de saturação e tensão de vapor d'água no ar. Pelos resultados encontrados neste trabalho as médias mensais de temperatura do ar no interior da estufa plástica foram superiores em 7,5%, a umidade relativa do ar em 7%, o déficit de saturação em 34% e a tensão atual de vapor d'água no ar em 4,7%, em relação aos valores determinados à campo. Observou-se maior efeito da cobertura plástica sobre as temperaturas máximas, as quais levaram as médias mensais a ficar entre 3,8 a 7,8 oC acima dos valores médios determinados no campo. Os valores médios mensais mínimos de temperatura e umidade relativa do ar entre a estufa e o campo apresentaram menor amplitude de variação que os valores máximos.

Absorção de nutrientes e alterações químicas em Latossolos cultivados com plantas de cobertura em rotação com soja e milho

The effects on soil chemical properties brought about by cover crops vary considerably. This study was conducted to evaluate nutrient uptake by five cover crops used for grain, seed and forage production at different seed densities per hectare, as well as uptake by spontaneous vegetation, and their effect on the chemical properties of two Oxisols when grown in rotation with soybean and corn. The experiments were set up in Votuporanga, SP, Brazil and Selvíria, MS, Brazil in March 2008 after conventional soil tillage. A randomized complete block experimental design was used with four replications with the following cover crops at different seed densities: Sorghum bicolor at 6, 7 and 8 kg ha-1; Pennisetum americanum at 10, 15 and 20 kg ha-1; Sorghum sudanense at 12, 15 and 18 kg ha-1; hybrid of Sorghum bicolor with Sorghum sudanense at 8, 9 and 10 kg ha-1; and Urochloa ruziziensis at 8, 12 and 16 kg ha-1. We also used a spontaneous vegetation control. After management of the cover crops, in the first year of study, soybean was sown in no-tillage system and, in the second year, corn was sown, also in a no-tillage system. We evaluated the dry matter yield of different cover crops, nutrient uptake by the cover crops, and the chemical changes in the soil. It was found that in clayey soils with high aluminum content, as in Selvíria, sudan grass at a seed density of 18 kg ha-1, and sorghum at a seed density of 6 kg ha-1, in combination with liming, contributed to reduction of aluminum content and high potential acidity and an increase in base saturation. The different seed densities of each cover crop did not affect the dry matter yield of the cover crop itself, but affected nitrogen uptake of the hybrid Sorghum bicolor with Sorghum sudanense at a seed density of 10 kg ha-1, with lower uptake than at a seed density of 8 kg ha-1. Seed density also affected the organic matter content in the soil with sudan grass, with the seed density of 15 kg ha-1 providing more organic matter content than a seed density of 18 kg ha-1.

Histologia hepática e produção em tanques-rede de tilápia-do-nilo masculinizada hormonalmente ou não masculinizada

The aim of this work was to evaluate the performance and the liver structure health of Nile tilapia hormonally masculinized or nonmasculinized, reared in cages with two protein levels. Two groups of Nile tilapia of Thai lineage (total 2,400), with 127 g initial average weight, were distributed in a completely randomized design with four treatments, in a 2x2 factorial arrangement, corresponding to the groups of hormonally masculinized or nonmasculinized fish, and to diet protein level of 28 or 32% of crude protein, with three replicates. After 115 days feeding, there was no interaction between the factors for final weight, weight gain, feed conversion rate, final length and survival. There was no difference between hormonally masculinized and nonmasculinized fish for final weight, weight gain, and survival, which shows the possibility of their production in cages, without the need of hormonal masculinization. Crude protein at 32% in the diet enables a better performance for both groups. Histological changes in the liver - such as increased cell volume, disruption of the cord-like arrangements, and increase of vesicles in the hepatocytes - are found in hormonally masculinized fish, and are more pronounced in fish fed 32% crude protein in the diet.

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.
