The study was aimed of evaluating the nutritive value of silages from five corn hybrids (AG 122, AG 9090, AG 5011, Dow 766 and DKB 747). The used five treatment with four replications in a completely randomized design to evaluate pH, ammonia nitrogen (N-NH3), dry matter (DM), crude protein (CP), ether extract (EE), mineral matter (MM), neutral (NDF) and acid detergent fiber (ADF), total carbohydrates (TC) and nonstructural carbohydrates (NSC). The ether extract rates (EE), mineral matter (MM), neutral (NDF) and acid detergent fiber (ADF) and non-structural carbohydrates (NSC) was not affected by corn hybrids. The AG 122, AG 9090 and DOW 766 did not differ significantly with values from pH the 3.42, 3.31 and 3.40, respectively. The AG 122 and DOW 766 showed maximum value of N-NH3 (2.89 mg/100ml). The lower values of N-NH3 was found in the AG 9090 (0.87 mg/100ml) and DKB 747 (1.05 mg/100ml). The DOW 766 and AG 9090 had higher value of MS rates, 33.51 and 32.32 %, respectively. In the silages, the pH and N-NH3 values had demonstrated that five corn hybrids supplying a good fermentation standard, all the corn hybrids can be classified like a good quality for silages.

The goal of this work was to evaluate the sulfur supply in soils of different textural classes using the mineral plaster originating of the region of Araripe-PE as sulfur source the sugar cane. They were installed 5 field rehearsals in different classes texturais soils to evaluate the effects of the mineral gypsum as sulfur source in the sugar cane plants nutrition. It searched the relations of the sulfur in plant, evaluating itself your availability. The rehearsals were led in the Zone of the Woods of Pernambuco. The experimental delineation employee was the one of blocks at random. The treatments in each rehearsal they constituted of the combination of 5 sulfur doses, with 3 repetitions (5 x 3). They evaluated the treatments at 16 months after the application of the sulfur doses calculated by the exchangeable aluminum neutralization and or calcium exchangeable content method, for the 0,4-0,6m soil depth layer. In the loamier soils and of smaller values of P-rem the sulfur doses promoted sugar cane larger production. The sulfur doses were enough for the sulfur supply for the sugar cane.

In aim to evaluate the nutritional value of shrimp meal its proximate chemical analyzed and a metabolism trial were done. The analyses performed on shrimp meal were dry mater (DM), ash, crude protein (CP), ether extract (EE), crude fiber (CF), gross energy (GE), calcium (Ca), and phosphorous (P). In the digestibility trial sixty broilers with fourteen days old were allocated in a completely randomized experimental design composed by three treatments, four replicates and five broilers per experimental unit. Treatments were a reference standard diet and two trial diets with 30 or 40% of substitution on the reference standard diet. Shrimp meal analyses resulted in 91.81 % DM, 16.31 % ASH, 66.01 % CP, 17.31 % EE, 9.38 % CF, 4726.51 kcal/kg GE, 4.70 % calcium and 1.44 % phosphorus in dry matter. Digestibility coefficient of DM from diets and shrimp meal does not differ but values for EE digestibility differed. In the levels of 30 and 40 % inclusion the mean calculated values of Apparent Metabolizable Energy (AME) for shrimp meal were 3,690 and 3,800, for AME nitrogen corrected (AMEn) the values were 3,478 and 3,554 kcal/kg, respectively.

An experiment was carried out at Universidade Federal Rural do Semi-Árido (UFERSA), Mossoró - RN, for screening the effect of substrate for germination of seeds and seedling growth of Moringa oleifera Lam. It was utilized a completely randomized design with four treatments (substrates: T1= 75% sand + 25% bovine manure, T2= 100% washed sand, T3= 75% sand + 25% worm castings and T4= 75% sand + 25% sawdust) and four replications of 25 seeds. The seeds were sown in the substrates contained in wooden boxes (7,5 cm long x 23,5 cm wide x 39 cm deep). Each box was filled with approximately 6 kg of substrate. The substrates were irrigated once a day (until the tenth day), then twice a day until the end experiment (19 th day). Seedling height, root length, number of leaves, whole seedling fresh and dry matter weights, germination velocity index and germination percent were evaluated. It was concluded that the mix 75% sand + 25% worm castings was the most suitable for the initial growth of moringa and the substrate containing 100% sand provided the best germination index for this species.

Bly. ex Rowl)) is native cactus the caatinga, much utilization of the small farmers in the drought period in the caatinga, To evaluate the xiquexique consumption for goats in the drought period in the caatinga, they were selected to the 12 animals in the community of the Xiquexique, Curaçá, BA, in the period of august to november of the 2005. The experiment consisted the two treatments and four replications. The animals consumed, on the average, 351.13 kg the phytomass the xiquexique. The daily consumption the xiquexique for animal was of 6.63 kg/dia. The animals thatreceived supplement had the period, while the other animals lost.

The objective of this work was to evaluate the effect of different doses of nitrogen and potassium applied through the irrigation water by micro-sprinkler in the space distribution of the root system of the soursop (Annona muricata L.), through digital images. The study was conducted at the experimental field of Embrapa - North, in Teresina - PI (05th 05 ' S and 42 and 48 ' W). The treatments consisted of the combination of five doses of nitrogen (20, 120, 200, 280 and 380 kg ha-1 year-1) with five potassium doses (30, 180, 300, 420 and 570 kg ha-1 year-1), besides the witness, applied every fifteen days. The evaluation of the length of roots was accomplished being used the software SIARCS and the results were analyzed through graphs of contour and columns. The largest concentrations of roots in relation to horizontal distance happened inside of the projection of the cup. The treatment whose doses of N and K2O were 380 kg ha-1 year-1 of N and 420 kg ha-1 year-1 of K2O it presented the best vertical profile of root distribution and it was also verified that dose high of potassium they inhibit the root development.

The guava is principally cultivated in tropical and sub-tropical regions. Brazil is one of the principal producers worldwide besides with India, Paquistan, Mexico and Venezuela. The fruit can be used in the industrialization generating many subproducts. The objective of this paper was to evaluate the efficiency of resistance inducers alone and associated with hydrothermal treatment in the control of anthracnose of guava. The fruits that were treated with Agro-Mos® presented minor severity in comparison to the others treatments (Crop-Set, Methyl Jasmonate and Chitosan). The Agro-Mos® was selected to be used associated with the hydrothermal treatment. The temperatures treatments, 47ºC, in any time of exposure and 50ºC in the time exposure of 3 and 6 minutes differs significantly to the others, independently of the association with the inductor.

This work aimed to evaluate the seeds germination and vigor of cv Golden papaya fruits after seeds and fruits storage. The papaya fruits were picked from two maturation stage, from Caliman Farm, in Linhares - ES. The fruits were conserved in 25ºC for 10 days and the seeds germination was evaluated at the 0, 2, 6 e 10 days. After extraction and washing of the seeds, the drying was accomplished using an oven-dried with air circulation at 30ºC until they reached 8 to 10% humidity. A part of the seeds was analyzed, immediately, as germination and vigor percentage (first count of germination test and percentage of strong seedling in first count of germination). Another part was stored in packings of the type pouch of flexible aluminum by 30 and 120 days in 15ºC. The experimental design used was completely randomized in 4x3 factorial scheme with four replications. The treatments consisted of four fruits storage period (0, 2, 6 e 10 days), with three seeds storage period (0, 30 and 120 days). The vigour was better availed by first count of germination test than by percentage of strong seedling. There were increase in the seed germination and vigor with the increase seed and fruits storage period. The fruit storage for 10 days and seeds storage for 120 days allowed hither seeds germination.

The in vitro propagation can provide the production of uniform plants, with high quality and free of diseases, and allow fast and genetically reliable multiplication of new cultivars and hybrids. In this context, the present work had the aim at developing a protocol for the in vitro propagation of Ananas lucidus Miller. Two experiments have been carried through, the first on the effect of BAP on nodal multiplication, an the second on plantlet acclimatization. For the multiplication it was used a completely randomized factorial design with 10 repetitions, and 2x5 factors, composed by two consistences, solid and liquid, and five BAP dosages (0,0; 1,0; 2,0; 3,0; 4,0) mg L-1. For the acclimatization experiment it was used a randomized blocks design with 5 treatments, 5 repetitions and 5 plants in each experimental unit, it being tested different substrata (coconut fiber, compost of plant residues, vermiculite, coconut fiber + compost, and vermiculite + compost). The number of sprouts (NB) produced in the liquid medium in the 2,0 mg. L-1 BAP dosage treatment was greater than in the 0,0 mg L-1 dosage, at a 5% probability level, and similar to the 1,0; 3,0 e 4,0 mg.L-1 dosages. It was observed that in the liquid media treatments there was a higher proliferation of sprouts than in the semi-solid media (11,3 and 9,0 respectively). The acclimatization survival index was of 96% for all treatments.

The Brazilian Cherry (Eugenia uniflora L.) is a native species of Brazil species native to the southern of Brazil. The aerial part of the plant (leaves and fruits) contains essential oil high in sesquiterpenes, which is used in the cosmetics industry and popular medicine. Although it has great potential, information regarding the distillation of its essential oil is scarce. The objective of this study was to evaluate the post-harvest treatments of the aerial part in order to improve the extraction of essential oil. The samples were collected from terminal branches of the same access of Eugenia uniflora L. belonging to the collection of aromatic and medicinal plants of the Center of Horticulture of the Agronomical Institute of Campinas, Sao Paulo State, Brazil, from May to June, 2005. The experiment was conducted in completely randomized blocks and a 2 x 2 x 2 factorial designs, with 3 replications, the factors being: two parts of the plant (leaves and branches), two methods of sample preparation (leaves and branches, whole or triturated) and two forms of the sample (fresh and frozen), totalizing eight treatments. The leaves were distilled in a modified Clevenger distiller for 3 hours. The frozen parts were kept for 7 days at -10oC before distillation. The highest concentration of essential oil is occurs in the leaves of Brazilian Cherry, with the twigs of the plant containing a small amount.. The freezing of the leaves reduced the oil yield as compared to that by others treatments, and the trituration of the vegetal material raised the extracted amount of oil.
