The aim of this paper was to evaluate the performance of lines of cherry tomato, heat tolerant under the organic system. The experiment was conducted at the Instituto de Ciências Agrárias da UFMG, Montes Claros - MG. The treatments consisted of eleven lines of cherry tomato, heat tolerant, obtained from the Asian Vegetable Research and Development Center, China: CLN1561A, CLN1555C, CLN1555B, CLN1555A, CLN1558B, CLN1558A, CH151, CH152, CH154, CH157, CH155 cultivated under organic system. We used a randomized block design with eleven treatments and four replications. There was an inverse relationship between the average fruit weight and number of fruits produced per plant. The lines CLN1561A and CH157 are indicated for the culture and commercialization of the cherry tomato organically produced, therefore to present greater productivity and greater total soluble solid content.

The aim of this paper was to evaluate the development of melon seedlings grown in different substrates. The experiment was carried out in a greenhouse covered with 25% screen, at the Department of Technology and Social Sciences -DTCS of the University of the State of Bahia / UNEB, Juazeiro-BA, from July to August 2005. It was used a completely randomized experimental design with six treatments and four replications, each one consisted of 50 seedlings. The treatments composed of the substrates: Plantmax HT©; soil; sterilized soil; sugarcane residue; sugarcane residue + soil (1:1) and sugarcane residue + urea. Polystyrene trays of 200 cells were used as containers, where seeds of the AF882 melon cultivar. We sowed at 1 cm depth, using one seed per cell. The emergence percentage, average emergence time and average emergence velocity were determined. Fourteen days after sowing were evaluated seedling height, shoot and toot fresh and dry masses leaf area and chlorophyll content. The results allow one to conclude that the commercial substrate Plantmax HT© and the sterilized soil were those that provided the best melon seedlings formation.

This research aimed at evaluating the effect of the semiarid climatic conditions on the physiological behavior of F1 Saanen x Boer crossbred goats, created at an intensive system. The experiment was carried out in the Health and Rural Technology Center, in the Federal University of Campina Grande, in the town of Patos, Paraiba. Twenty-four animals were used, with ages varying between three and four months, being 12 females and 12 males, weaned and prevented against worms, receiving ad libitum water and controlled concentrate and roughage. The environmental variables were checked inside and outside the experiment place, as well as the physiological variables of all animals. Except for the humid bulb temperature, the variance analysis revealed shift effect (P<0.05) for all environmental variables. There was merely shift effect (P<0.05) for Cardiac Frequency and Rectal Temperature, and the averages of both, in the afternoon, overcame those observed in the morning. The obtained results based on the studied physiological and environmental variables conclude that crossbred goats, resulting of Boer (paternal) and Saanen (maternal), present a good resistance to heat, permitting their indication for the meat production in confinement on semiarid conditions.

Water is a limiting factor for crop yields, for example yellow passion fruit, requiring from use of irrigation due to limitation of surface waters. This study aimed to evaluate irrigation levels and fruits quality in yellow passion fruit production in Semiarid conditions, thus an experiment was carried out. The seedlings were grown in greenhouse and transplanted in the field spacing 4 m x 2 m. The treatments studied were five water levels: 60; 80; 100; 120 and 140% from ETo, applied through drip irrigation with 4 repetition. The parameters evaluated were average fruit weight (g), yield (t ha-1), the pulp yield with seed (%), juice yield (%) and skin percentage (%). The results obtained in the experiment showed that the highest yield of hybrid passion fruit with average weight over 150 g, and the highest yield was obtained with the blade of 120% ETo. The yield of pulp with seeds was negatively affected by increased volumes of water for irrigation. Can use plant 120% ETo for the irrigation of yellow passion fruit 'IAC 273/277¿ to optimize production and improve fruit quality in semiarid conditions.

O objetivo deste trabalho foi analisar a uniformidade de aplicação de efluente de três sistemas de irrigação abastecidos com diferentes características de esgoto doméstico do condomínio residencial Bosque Acamari, em Viçosa-MG. O experimento foi realizado em área de pesquisa da Universidade Federal de Viçosa (UFV), em Viçosa-MG. Montaram-se três sistemas de irrigação por gotejamento, abastecidos com esgoto doméstico preliminar (EDP), esgoto de tratamento secundário (EDS) e esgoto de tratamento terciário (EDT). Cada sistema de irrigação foi composto por filtro de discos e gotejadores não autocompensantes com vazão nominal de 1,7 L h-1. A uniformidade de aplicação de efluente foi obtida a cada 100 h, totalizando 500 h de operação, com os Coeficientes de Uniformidade de Distribuição (CUD) e de Uniformidade Estatística (Us). Foram realizadas determinações físico-químicas e microbiológicas nos esgotos domésticos. Conclui-se que as características ferro total e coliformes totais representam risco severo de obstrução para gotejadores abastecidos com EDP, EDS e EDT, enquanto para as características manganês total, magnésio e cálcio tal risco é baixo. A formação de biofilme de sólidos suspensos e bactérias foi a principal causa de obstrução de gotejadores. Os valores de CUD e Us apresentaram, após 500 h de operação, redução de 61 e 54%; 27 e 24%; e 57 e 59%, respectivamente, para os sistemas de irrigação abastecidos com EDP, EDS e EDT.

In the Brazilian northeastern, goat and sheep are a complementary income for family farmers, mainly through the production of leather skin and/or meat. The aim of this work was to characterize sheep and goat's production systems practiced by local farmers in Jussara and Valente - Bahia (Brazil) through the analyses of nutrition, sanitary and reproductive practices. Data on 46 producers were collected through a structuralized script and later analyzed through descriptive statistical techniques. There was greater frequencies and medium from sheep than goat. The sheep breed Saint Ines and goat breed Anglo-Nubiano predominate in the crossbreeding with local breeds. The nutritional management was based on caatinga vegetation with supplements. The sanitary management was deficient, mainly in relation to worms. The reproductive management, although the general situation of traditional systems, showed better indices. Thus, the systems studied are family- based, diversified among stages of production. Although presentations for own consumption or subsistence systems, particularly the sheep production have a tendency of expansion and specialization.

It was evaluated the influence of doses of KCl applied to soil and to the leaf axil of the the quality of the fruit and on the concentration of K in the water and peel of the fruit. The experiment was carried out at a commercial orchard of green dwarf coconut tree (Cocos nucifera L.) in Campos dos Goytacazes, Rio de Janeiro state, Brazil, in a typical Ortic Quartzarenic Neossol, during one year, using a randomized complete block design with five treatments and sixteen replicates. The treatments consisted in two application ways (in the soil and in the axil of the leaf number nine) and two manuring levels (1666 and 3333 g of KCl plant-1 year-1 in the soil and 833 and 1666 g plant-1 year-1 in the leaf axil, with three month intervals), besides a control, without KCl. The application of KCl resulted in the increase of the concentration and of the content of K in the water and in the peel of the fruit. There was no influence of potassium fertilization on the mass, the volume, the pH, C.E. and SST of the coconut water. The application of high doses of K should be reviewed in view of the low recovery rate of the potassium fertilizer.

Due the expansion of atemoya cultivation and its increasing consumption in the principal Brazilian markets, it is necessary to investigate the postharvest physiology of fruit as well as the use of technologies to increase their shelf life. The purpose of this paper was to evaluate the quality attributes of atemoya 'Gefner' harvested in two maturation stages. The fruit, from commercial plantation located in Neopólis, SE, Brazil, were evaluated at harvest and after three days, staying at 25 ° C throughout the experiment. The experimental design was completely randomized in a factorial 2 x 4 (maturity stage x time), with five replicates. The characteristics evaluated were: color, firmness, weight loss, color, soluble solids (SS), titratable acidity (TTA), pH and vitamin C. The color, the mass loss and the SS and ATT increased during storage, with decrease in pH and a dramatic reduction in the level of vitamin C. The storage time directly influenced all traits. Among the stages of maturation, only firmness differed significantly and may be used as an indicator of ripeness.

We studied the spatial distribution of a galling insect species that induces galls on the leaf veins of Caryocar brasiliense Camb. (Caryocaraceae) trees. Galls/leaflet predominantly occurred at the northern (1.06) tree slope, with decreasing number at the western (0.92), eastern (0.65), and southern (0.60) slopes. Higher number of galls/leaflet were found in the interior of the tree crown, i.e., on the proximal region (1.99) of the stems compared to the terminal portion (1.26). On the other hand, the average number of vein galls/leaflet did not differ statistically among the three leaflets of C. brasiliense (right = 0.79, central = 0.78, left = 0.84). Galls/leaflet were most abundant on the distal (0.46) and median (0.52) regions compared to the proximal (0.24) longitudinal region of the leaflet. This gall/leaflet insect was most frequent on the central (1.01) portion than in the leaf margin (0.05) or near mid vein (0.14) on transversal regions of a leaflet. Keywords: Savanna.

The production of jelly is an alternative to the use of fruits that did not meet the classification standard, helping to reduce post harvest losses of up to 40% of total production. This study aimed to evaluate the sensory quality of jelllies produced mixed with watermelon (Citrullus lanatus Schrad.) and tamarind (Tamarindus indica L.). Six jelly formulations were prepared using pulp from watermelon and tamarind in different proportions: F1 (100% watermelon pulp), F2 (87.5% watermelon pulp and 12.5% tamarind pulp), F3 (75% watermelon pulp and 25% tamarind pulp), F4 (12.5% tamarind pulp and 87.5% water), F5 (25% tamarind pulp and 75% water) and F6 (37.5% tamarind pulp and 62.5% water). All jellies containing pulp and sucrose in the ratio 1: 0.6 and the final soluble solids was 67 ºBrix. The attributes of color, texture, taste and preference of the jellies were evaluated by 50 untrained panelists using a hedonic scale of nine points (ranging from "like extremely" to "dislike extremely"). The worst consistency was found in F4 and the largest concentration of tamarind in jelly impaired color impacting negatively on the product acceptance. The jelly mixed F2 had the best score for taste and preference attributes that jelly F6.
