Características agronômicas, bromatológicas e econômicas de alturas de corte para ensilagem da cultura do milho

The aim was to evaluate agronomic, bromatologic and economical characteristics harvest heights for ensiling of corn. The trial was conducted in randomized block design and treatments corresponded to harvest heights of 20; 50; 80 and 110 cm from the soil surface. The agronomic evaluations were conducted 114 days after planting. The percentage of dry matter (DM) and productivity of stem, grain and participation of potassium remaining in the stem increased linearly with increasing cutting height (p<0.05). Therefore, the mass used at ensiling decreased proportionally with increasing cutting height (p<0.05). The silage quality was improved because of the increase in the cutting height. We observed higher crude protein (CP) content and energetic value in the silage harvested at 110 cm from the soil surface, while there was lower fiber content. However, silages produced with plants harvested at 110 cm from the soil surface showed the highest production cost (4.47 times greater than cycling through K in the remainder of the stem). The agronomic and bromatologic characteristics of corn silage improves with increasing cutting height, but the increase cutting height unfeasible economically the practice silage when the generation of final products is not computed. Thus, it is recommended that the cutting height of the corn plant is at most 50 cm.

Desempenho e uso eficiente da terra de modalidades de consorciação com milho e forrageiras

This study was developed with the aim of evaluating the performance and land use efficiency of different arrangements of intercropping with maize and forage. The field experiment was conducted in Tangar da Serra/MT. The experimental design was a randomized block in factorial scheme 3x2 + 1, were as three arrangements of intercropping, two species of forage and an additional treatment with maize monoculture in four replication. In maize monoculture and intercropping were evaluated: plant height and ear insertion height, plant population, weight of 100 grains, productivity, number of grain rows and number of grain per row. In forages intercropping with maize were evaluated plant population and dry matter accumulation. The arrangements with Maize + Forage sown in the line and Maize + Forage sown in two rows between rows with the species Urochloa hybrid promoted best corn yields. The modality and species affect both the productivity of maize as forages species. Grain yield of maize is higher in monoculture. The higher dry matter accumulation of Urochloa hybrid occurs in the Maize + Forage sown in one row between rows, while, for the Urochloa brizantha the arrangements studied do not affect their yields. The arrangement with best land use efficiency is Maize + Forage sown in two rows between rows for both study forage species.

Vibração de plantas de pimenta Malagueta para produção de frutos e sementes em ambiente protegido

This study aimed to verify the effect of vibration of plants in the production of fruits and seeds and in the physiological quality of the seeds of the “Malagueta” pepper in a protected cultivated area with open and closed sides. The experiment was conducted at the Experimental Farm of the School of Agronomic Sciences of Universidade Estadual Paulista (FCA/UNESP), located in the city of São Manuel (SP). Two treatments were carried out, which consisted of plants that did and did not undergo vibration. Plants were vibrated manually by swinging the wire attached to the supporting bamboo for about 5 seconds, twice a day for 11 weeks. The design was a randomized block with six repetitions. The same experiment was conducted in two protected environments, with and without anti-aphids screens on the sides, cultivated in the same season. For the comparison of environments, a combined analysis was performed considering each environment as a separate experiment. The characteristics evaluated were: weight and number of fruits per plant; weight, diameter and length of fruit; weight and amount of seeds per fruit; and plant height. For the analysis of seed quality, the characteristics evaluated were: germination percentage; first count of germination; dry matter of seedlings; seedling emergence in substrate; and seedling emergence speed index. Regardless of the environment, vibration affects the physiological quality of seeds. The presence of pollinator insects benefited the production and quality of “Malagueta” pepper seeds and increases the fruit weight.

Batata cv Pirassu como matéria prima industrial

The starch market has been growing and improving in recent years, leading to a search for products with specific characteristics that meet the industrial requirements. This work aimed to evaluate the centesimal composition of potato tubers cv Pirassu and its industrial potential. The potato cv Pirassu was cultivated in Pouso Alegre, mountainous region south of Minas Gerais state, with planting season in August and harvest season in November, 2011. The tubers were analyzed for color, pulp and centesimal composition. The starch extract was analyzed for centesimal composition, phosphorus content, apparent amylose, pasting properties and thermal properties. The results showed that the content of dry matter, total soluble sugar and starch of tubers, are compatible for processing for potato chips. The starch of this cultivate showed important viscosity characteristics for food industry such as: heat resistance and friction, good final viscosity and low granular organization.
