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.

This work objectified to study the nutritional composition of the espinheiro (Machaerium aculeatum Raddi.), in dry and rainy season under pasture of Brachiaria decumbens Stapf in the conditions of Itambé, Pernambuco, Brazil. The experiment was carried out at Experimental Station of Itambé, of the IPA. It was identified 20 trees of the specie in the pasture, in which were realized eight collections of leaves and twigs (diameter<0.5 cm), half at the dry period and half at the rainy period. It were determinate the dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), potassium (K), nitrogen (N), calcium (Ca), magnesium (Mg), and phosphorus (P) contents. The CP, ADF, K, N, Ca and Mg contents were larger (P<0.05) in the rainy season, with average 14.7; 39.7; 1.7; 2.3; 1.1 and 0.5%, respectively. NDF and P contents had not differed between the seasons, with average 49.1 and 0.1%. The espinheiro presents similar chemical composition to the one of other legumes forages. The season of the year exerts influence on the chemical composition of the espinheiro.

With objective to study the effect of the powder of neem (Azadirachta indica L.) dryness and green leaves on the quality of cowpea (Vigna unguiculata L. Walp.) seeds, was installed an experiment in the technology of seeds laboratory of the ESAM-RN. Was utilized seeds drip-gold cultured originated of Sierra of honey municipality, submitted four doses (0,25; 050; 0,75; 1,0g) by fifty seeds of powder of neem dryness and green leaves. The experiment was in completely randomized design with eight replications in a factorial arrangement 2 x 4 + 1. The values were submitted variance analyses and compared through tukey test with 1% probability used SISVAR program. NPDL and NPGL caused no toxic effect to seedlings as evaluated through first count of emergenced seedlings, germination rate and dry matter loss in seedlings.

Sunflower crop is a good option of income generation because of its grains commercialization and oil extration. The lack of knowledge about performance of genotypes at local conditions is one of the problems to the installation of this crop in the Maranhão State The objective of this work was to evaluate sunflower genotypes and to verify its productive potential in the Maranhão State. The aquenio yield, oil content, oil yield, initial flowering, physiological maturation and height of plants had been evaluated. It was observed that genotypes showed a low average aquenio yield (348 kg/ha), but their average oil content was sactisfatory. ACA 884, Helio 358 and Agrobel 962 had the best results for all of agronomical characteristics evaluated.

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.

The experiment was carried for 12 months in the Rabbit Unit of Departamento de Zootecnia at the Universidade Federal do Ceará. The aim of this work was to evaluate the rabbit reproductive parameters and ponderable performance of the races New Zealand (NZ) and Califórnia(CA) , in Ceará, Northeast Brazil. Animals were fed with a commercial feed of 2500 kcal DE/kg for rabbit in reproduction. Thirty does (50% of each race) were distributed at random in experimental cages, such that each ¿treatment¿ (race) had 15 replications. Data were analyzed in a complete randomized design. Does were selected by weight and age, being included in the expeiment with 3,0 kg and 4,5 months of age, approximately. The male/female ratio was 1:10. Pregnancy check was done by palpation 15 days after mating. Reproductive management adopted was mating 10 days after delivery and weaning at 30 days of age (semi-intensive). Productivity in maternity was similar between races. Numeric productivity for both races was 31.3 rabbits weaned/cage/year. Does CA showed greatest maternal ability as compared with NZ does, with heavier offspring at birth, at 21 days, and at weaning. Finally, it is suggested that to produce a rabbit for slaughtering, it should use females CA with males NZ, in single or industrial mating.

The objectives of this research were to report Meloidogyne mayaguensis on seedlings of guava (Psidium guajava) cv. "Paluma" in commercial nursery in Assu municipality and in commercial field of pipper (Capsicum annum) cv. "Comandante" in Baraúna municipality, in Rio Grande do Norte State and to notify all of segments involved to commercial growing of fruits and vegetables about the risk that seedlings infected by this pathogen represents to the agro-centers of Rio Grande do Norte and Ceará States. Concerning to both reports the identification of pathogenic species was made by the a-esterasic fenotype characterization. The present reports of M. mayaguensis represent the second and the third ones in Rio Grande do Norte State,having been made the first one on plants of guava in Touros municipality. Meloidogyne mayaguensis can represent a threat to commercial growing of fruits and vegetables if eradication and exclusion methods of control will not beused.

The aim of this work is to approach the prevalence of pathological alterations of the genital system of anestrous females of collared peccaries (Tayassu tajacu). The genital systems of 14 matrices proceeding from the Centro de Multiplicação de Animais Silvestres - CEMAS, of the Universidade Federal Rural do Semi-Árido - UFERSA , that were without activity breeding for a period above of one year had been studied. After it abates of the animals had been collected the agencies that compose the genital system and lead to the Laboratory of Animal Pathology of the Institution for pathological alterations evaluation. The joined pathologys had been hydrosalpinges and ovarian hypoplasia with four cases each (28.6%),one (6.7%) case of persistent corpus luteum associate to mucometra and 2 (14.3%) cases of ovarian cysts. The pathologys of the genital system of collares peccaries can, in changeable way, to compromise temporary or the fertility permanently, diminishing the reproductive effectiveness, with consequent reduction of the breeding, generating economic losses .

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 Districtand 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.

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 greaterthan 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.
