This work makes a approach of the familiar agriculture of the Assentamento Redonda in the City of Icapuí in the State of the Ceará, objectifying tytisy to identify, to classify the familiar agriculturists having for base the survival strategies put in practical for these actors in the process of local development. The methodology adopted in the work searched to make possible adequate knowledge of the agricultural activity and the agricultural agriculturist, through the analysis of economic performance and parameters that they make possible to measure the stimulus to the investment in the production, as well as the degrees of integration to the market and specialization of the production. In accordance with the gotten results, in the studied locality, the properties are considered integrated to the market and possess greater specialization in the cattle production and of cashew chestnut. Between the studied producers, it has low stimulus to invest in the farming production; this if must to the fact from that the majority of the income of the seated ones is proceeding from other sources as: retirements, pensions, stock market family (bolsa família), wages and others, what it becomes the agricultural activity relatively less attractive. Words Key: Tipificação, Familiar Agriculture, System of Production, Icapuí-ce.

In order to evaluate the response of Nitrogen and Simple super phosphate fertilization in the growth of yellow passion fruit (Passiflora edulis Sims f. flavicarpa Deneger) seedling an experiment was carried out at shady chamber (50%) at Agricultural Department of Universidad Federal de Lavras (UFLA). A randomized block design was used with factorial scheme 4x4, with four replications and five plants by plot. It was used 4 doses of Nitrogen (0; 800; 1600 and 3200 mg N dm-3 of substrate) and 4 SS doses (0; 2,5; 5,0; and 10,0 kg m-3 of substrate. It was evaluated the characteristics: high of plants ( cm), root length (cm) number of leaves/plants, dry matter of aerial part and root (g/plant). ). It was verified that the nitrogen fertilization in cover warranty best quality in production of plants of yellow passion fruit. The simple super phosphate not showed good results substrate formulation to formation of seedlings of yellow passion fruit.

This paper reports the first occurrence of Hoplolaimus galeatus associated to banana (Musa sp.) var. "Gran Naine" rhizosphere in Ceará State, Brazil.

The objective of this experiment was evaluate the effect of nitrogen nonproteic (NNP), that is urea and ammonia sulphate, replace to soybean meal in the supplementation of milk cows fed with differed buffel grass and cactus forage. The work was carried out at IPA - Experimental Station in Serra Talhada - PE. Eight cows were fed in a 7.5 ha area, four from the Guzera race and four from the 5/8 Holstein/Zebu. They were supplied with 38 kg of cactus forage (P) and soybean meal (FS), being replaced by urea + ammonia sulphate (U+SA). The experimental design was the Latin Square, and the treatments were P + FS (1.69 kg FS); P + 2/3FS + 1/3U (1.13 kg FS + 97 g U+SA); P + 1/3FS + 2/3U (0.56 kg FS + 195 g U+SA) e P+U (292 g U+SA). The 5/8 Holstein/Zebu cows were more productive than the Guzera, with the production of 7.08 and 7.31 against 4.67 and 5.34 kg/day, respectively, for milk and corrected milk for 4% of fat. There was no difference among the treatments or interaction race x treatment, so that the NNP could substitute soybean meal in the conditions of developed experiment.

This work was carried out to measure the adaptability on the heart rate (HR), respiratory frequency (RF) and rectal temperature (RT) in Boer and Anglo-nubiana goats at Meio-Norte, Brazil. Fourteen male goats were used (7 = Boer and 7 = Anglo-nubiana) in the same conditions. In the same days and times were too collected the temperature and (TA) and relative humidity of the air (UR). The SNK test was used to compare the means. The results obtained to Bôer and Anglo-nubiana was, in dry period, HR (beats/minutes) = 79.3±16.1 and 97.0±18.3; RF (mov.min-1.) = 25.5±5.9 and 34.4±13.3; TR (oC) = 39.2±0.4 and 39.4±0.4. In rain period, in the same breed order HR = 75.1±6.9 and 82.5±6.0; RF (mov./min.-1) = 27.7±4.47 e 26.7±5.5; TR (oC) = 39.3±0,4 and 39.4±0,4. The TA, in oC, and UR, in %, were in the dry period 33.0±1.5 and 55.0±7.43; and in the rain period, 30.0±2.02 and 81.2±6,99. The Anglo-nubiana goats showed the highest HR, RF and RT relative to the Boer goats in the dry and in the rain periods that indicate the Boer goats are better adaptable in the hot stress conditions.

The objective of this work was evaluating the principal alterations of the chemical properties of quality of the papaya 'Formosa' under refrigerated storage. The harvest of fruits was accomplished in a commercial planting located in the municipal district of Baraúna-RN. The storage happened in cameras under controlled conditions of temperatures (8, 10 and 12 ºC ± 1 ºC) and relative humidity of the air (90 ±5%) during periods of 7, 14, 21 and 28 days. After each period, the papayas were transferred to environmental conditions (20 ± 1oC 60 ± 5% UR) where a period of shelf life of seven days was simulated. Then, the papayas were analyzed regarding the titratable acidity (ATT), C vitamin, total soluble solids (SS), starch, reducing and non-reducing sugars. A completely randomized experimental design was used, in a factorial 3 x 4 outline (temperatures x time of storage), with five replications and two fruits per plot. The best extension for the post harvest useful life of papaya 'Formosa' was esteemed for the fruits submitted to 10 °C and 90 ± 5% UR up to 20 days, with soluble solids above 12% and C vitamin around 40 mg×100 g-1. The fruits submitted to 8 °C, 90 ± 5% UR had the worst estimates, presenting the smallest contents of SS.

The objective of this work was to evaluate sowing depth and seed dormancy breaking method in the formation of seedlings of the soursup rootstock cv RBR. The experiment was conducted under greenhouse conditions at the orchard of the Lavras Federal University - UFLA. The experimental design was in randomized blocks in a two factors arrangement (4x3), with four replicates and five plants per plot. The dormancy breaking treatments were: witness (control); immersion in water (25 °C for 12 hours); immersion in water (25 °C per 24 hours) and side cut on the seed. The seeds were sowed at 1, 2 and 3 cm of profundity. The characteristics evaluated were germination velocity; germination percentage and after 120 days of sowing the seedlings height (cm); rootsand aerial part fresh matter (g) and roots and aerial part dry matter (g) were also evaluated. There was notinteraction of dormancy brake treatments with the seeds profundity. Seed germination was not influenciated by theprofundity that the seeds were sowed. The side cut on the seed did not provide different results of germination percentage and germination velocity compared to the other treatments, but presented higher of seedlings height.

The contamined soil with the forms infect of the parasites, transmitted by feces of animals, it represents high risk of zoonoses transmission. Among the helmintos species, they meet agents producers of the cutaneous migrans and visceral migrans larvae. In this context, the present work had for objective to contribute for the study of the cutaneous migrans larvae, identifying your agents producers and associate the results with the obtained data of the medical registrations of dermatological center in the Mossoró-RN. The study was accomplished in the Mossoró District and beaches of Areia Branca and Tibau District, region west of Rio Grande do Norte State, removing soils samples of the 29 public squares, 07 schools and 04 beaches, to which was processed at the Laboratory of Animal Parasitology - UFERSA, by modified Baermann method. In overall, 200 samples of soil were collected originating from 40 different places, of these, 35% (14) presented growth for Ancylostoma sp, being distributed in 78,6% (11) squares, 14,3% (2) schools and 7,1% (1) beach. The larger occurrence of the helminto was verified in the months that presented higher pluviometric index and in the studied period 92/770 patients positive for worms migrans cutaneous according the medical registrations.

With the purpose of evaluating effects of salinity of irrigation water on initial development of rootstocks of guava (Psidium guajava L), an experiment was conducted in greenhouse at Experimental Station of Pacajus, belonging to Embrapa Tropical Agroindustry in the State of Ceará. The treatments in randomized block design consisted of five levels of electrical conductivity of water (ECw: 0.5; 1.5; 2.5; 3.5 and 4.5 dS m-1) and two cultivars of guava (Rica and Ogawa) with four replications. The irrigation waters were prepared maintaining equivalent proportion of 7:2:1 respectively of Na:Ca:Mg. Seedlings were appraised 80 days after emergence, the effects, on number of leaves, plant height, diameter of stem, phytomass of the root and aerial parts, total phytomass, diameter, leaf area and root to aerial part ratio were studied. The increment of water salinity affected growth of cultivar in terms of number of leaves, stem diameter plant height, the Ogawa cultivar was found to be more affected. In highest level of water salinity (4.5 dS m-1) the relative reduction in total dry phytomass in case of cultivar Rica was 63.5% while the decrease in cultivar Ogawa was higher (77.4%); with regard to leaf area the effect was linear with reduction of 17.2% and 18.4%, respectively, for unit increase of water salinity. In cultivar Rica roots and in cultivar Ogawa the aerial parts were most affected negatively by water salinity.

The objective of this paper was to know the species of the leafminer (Diptera: Agromyzidae) associated with melon plant Cucumis melo L., in the Chapada do Apodi, semi-arid region of the Rio Grande do Norte state, and report losses due to leafminer mining. This way, leaves infested with leafminer larvae were collected in the field and carried to laboratory, in order to obtain pupae. These pupae were placed inside glass containers until adults emergence. All identified adults belonged to Liriomyza trifolii (Burgess). In some farms leafminer caused losts that range from 10 to 15% of the whole area, due to low fruit ºbrix value. From pupae also emerged some Opius sp. (Hymenoptera: Braconidae) individuals, a leafminer natural enemy, endoparasites the larva-pupae of L. trifolii.
