The objective of this work, the performance of three varieties of soybean on "Tabuleiros Costeiros" State of Alagoas. The installation of the experiment occurred on March 20, 2006, picking up the parcels on 26 August 2006. The experimental design was a randomized blocks with seven repetitions. The experimental plots consisted of ten rows of 4.0 m in length, spaced 0.50 m. In ten plants per plot were marked certain height of the plant in full bloom stage R2 and point of harvest stage R9 considering the distance between the soil surface and apical end of the main stem, the body weight of 100 seeds, grain production and dry weight in (kg ha-1) which are calculated from the production harvested per plot. The soybean plants of three varieties showed height below the minimum required for mechanical harvesting. The three varieties yield or more of the traditionally producing. The average of dry matter accumulation obtained show the variety BRS Tracajá as a good option for the production of forage.

A field experiment was developed in the period of April of 2000 to May of 2002, at the Experimental Station of Jiqui pertaining to the Empresa de Pesquisa Agropecuária do Rio Grande do Norte - EMPARN, Parnamirim city, state of Rio Grande do Norte. The work had as objective to evaluate the effects of nitrogen and potassium applied through irrigation water on the vegetative behavior and productive of green dwarf coconut tree (Cocos nucifera L). The treatments had consisted of the combination through the experimental matrix of Pan Puebla III, 5 doses of N and 5 doses of K2O both oscillating of 135 the 2565g plant -1 year -1 derived of the urea and potassium chloride. The used experimental design was of blocks at random with 4 repetitions and 5 plants for plots totalizing 40 experimental units. The plantation was made in the triangular spacing of 7.5 m between plants and 7.5 m between lines. During the 5th year of culture, from April of 2001 to May of 2002 was quantified the number of fruits in the 13 harvest carried out. The referring variables to the vegetative development, height and circumference of stem, diameter of the top and leaf number, had been measured in May of 2002, in the end of the experiment. The stem circumference increased linearly with the increase of the doses of N and of quadratic form with the doses of K with the biggest value for the dose of 1350 g plants -1 year-1. The leaf number answered only the nitrogen applications. The growth in stem height had influence of N and K, however, data did not adjust to no mathematical model. The diameter of the top of the green dwarfed coconut palm did not suffer significant interference of no applied fertilizer through irrigation water. The number of fruits increased quadratically with the N and K doses. The maximum physical efficiency of the production, 154.75 fruits plants -1 year -1, it was reached with the doses of 1437 g plants -1 year -1 of N and 1553 g plants -1 year -1 of K.

The aim was to survey the floristic, structure and to characterize data of Capparis flexuosa L. in an area in the semi-arid of Paraiba State. Ninety-nine contiguous parcels of 10 m X 10 m have been established for measured standing specimens whose trunk measured ¿ 3 cm of diameter at ground level (DNS) and whose total height was ¿ 1 m. The index of diversity of Shannon-Wiener (H') and equability of Pielou (J'), density, frequency, dominance, Value of Covering (VC), Value of Importance (VI), diameter-class and height-class were calculated. It was verified that plant mean density was 2879 ind.ha-1, with 2850 individuals belonging to 22 species, 18 genera and 12 families. H' = 1.75 nats.ind-1. The value J' = 0.57 showed an ununiformity in the species distribution in the studied parcels. Capparis flexuosa was the fourth species with greatest relative density (6.04%) and relative frequence (12.43%) indicating a good distribution in the studied area; the first in relative dominance (26.03%), the third in VC (16.03%) and the fourth in VI (14.83%), suggesting that this species is well adapted to the edafoclimatic conditions of the studied area. We observed that 1.975 individuals were found between 3-6 cm of diameter and 2716 between 2.01 - 5 m height.

With the objective in determine the contribution of the clay and of the organic matter for CTC of the soils of the State of Alagoas, with base in data of the rising exploratory-recognition done by JACOMINE et al.,(1975) 265 representative samples were used of the horizons A and B of 64 profiles of the different areas of the State. The CTC of the fraction clay corrected by the organic matter is presented by area and in the general for the State: Coast CTCargila = CTCsolo - (% C x 4,4) /% clay x 100; Forest CTCargila = CTCsolo - (% C x 4,7) /% clay x 100; Rural CTCargila = CTCsolo - (% C x 5,6) /% clay x 100; Interior CTCargila = CTCsolo - (% C x 4,7) / %argila x 100; São Francisco CTCargila = CTCsolo - (% C x 3,1) /% clay x 100; General CTCargila = CTCsolo - (% C x 4,6) /% clay x 100;. It is presentedre a presentative model of equation for determination of CTC of the fraction clay (Targ) and of 1 gram of carbon (TC) (cmolc clay kg-1) for the State of Alagoas: Targ (Y) = 17,27 - 1,0976ArgB + 0,01276ArgB2 + 4,9748TB - 0,05526ArgB.TB (R2 = 0,989) and TC (Y) = 1,2189 - 0,0531ArgA + 0,0722ContA (R2 = 0,664). It's presented average, medium, minimum, maximum, standard deviation, asymmetry and curtose of the clay tenor, organic carbon, CTC and contribution of the organic carbon for area and in the general for the State, being also applied for CTC of the clay (Targ) and CTC of 1 gram of carbon (TC).

Metarhizium anisopliae var. anisopliae and Metarhizium flavoviride var. flavoviride are entomopathogenic fungi with proved action against several species of insects. In this work, the behavior and cytology of the M. anisopliae var. anisopliae (PL43) and M. flavoviride var. flavoviride (CG291) were evaluated after the passage in eggs, larvae and adults Chrysomya albiceps, an important causer of secondary myiais. The experiment was carried out under an acclimatized environment's humidity and temperature of 60 ± 10% and 28 ± 1oC. The most expressive results of the biological parameters studied (percentage of germination, quantity of conidia, quantity and diameter of colonies) were reached from re-isolated fungi of larvae. No significant differences were observed in the cytological aspects of the life cycle of the fungi post-passage in eggs, larvae and adults. These results suggest the possibility of the use of the fungi in the control of C. albiceps fly.

The evaluation of the effect of seed has been fundamental tool in the program of quality control, and the accelerated aging test, an important part of that process. Some authors report that the germination and vigor are associated with seed size and facing the lack of consensus for the use of this test methodology and the relationship of seed size on the physiological quality, this work aimed to adapt the existing methodology as the temperature and period of conditioning on the performance of two sizes of seed cotton. The seeds were classified into two meshes of sieves, and then subjected to tests of water content, germination and electrical conductivity. The experimental design was completely randomized, analyzed statistically in a factorial threefold. Seeds of different sizes, showed no difference in percentage of germination. Seeds subjected to 40 º C for 42h of conditioning showed better percentage of germination.

The study aimed to evaluate the effect of two doses of organic material in the nutrition of tomato (Lycopersicon esculentum), cv Santa Cruz, grown in pots in an Oxisol Ultisol Distrocoeso the municipality of Rio Largo - AL. The design was in randomized blocks in factorial 2 X 4 (two and four fertilizer doses) with 5 replicates. The experimental unit consisted of a vessel with capacity for 12 dm3 containing 15 kg of soil. The fertilizer materials were: 1 fertilizer - manure from corral + chicken manure + fertilizer and the filter cake of 2 - to corral manure + chicken manure + sugar cane bagasse, in doses 0, 5, 10 and 15 t ha-1. The applications were split in the following way: 10% at the time of transplantation, and 15% at 20, 34, 48, 62, 76 and 90 days after transplanting (DAT) in coverage. The seedlings were produced in the tomato seed, on March 10, 2008, in polystyrene trays with 128 cells, after transplantation and were selected for the vessel on April 02, 2008, leaving two plants per pot . The plants were conducted in mentoring and single stem, and where, therefore, all cultural and treatment plant. There was a collection of leaves 4 + from the apex of the plant, to assess nutritional status at the beginning of flowering. Among the nutrients, the nitrogen was absorbed the most, followed by: potassium, calcium, sulfur, magnesium and phosphorus, whereas among the micronutrients, in increasing order of absorption was the following: boron, zinc, copper, manganese and iron. According to analysis of variance and regression analysis of the fertilizer did not affect the levels of nutrients in the plant, with only difference between the doses.
