Biometric analysis is of great importance for the evaluation of the characteristics of the seeds, being used to predict the physiological aspect. In this context, the objective was to study the biometry of seeds of cowpea bean varieties cultivated by family farmers in the Brazilian Northeast. The work was carried out from April to July 2018, consisting of the harvesting of cowpea bean seeds in the agroecological production area, of the region of Apodi, Northeast Brazil. A completely randomized design with six treatments (owl, canapum, lizão, always green, cow’s rib plus cultivar BRS potiguar) and six replicates of 100 seeds was used. A completely randomized design with six treatments and six replicates of 100 seeds was used. The evaluated characteristics were: length and width of seeds, expressed in mm; length/width ratio of seeds, expressed in mm; weight of one hundred seeds, expressed in g; weight of one thousand seeds, expressed in grams and quantity of seeds per kg, expressed in units kg-1. There was a statistical difference between the varieties of cowpea for the biometric characteristics studied. The cowpea variety was statistically superior to the others, for the characteristics, seed length (11.37 mm), length (2.14 mm) length ratio, weight of one hundred seeds (31.16 g) and weight of one thousand seeds (312.46 g). The BRS potiguar variety was statistically superior to the characteristic number of seeds per kilo (5099.16 units kg-1).

<p class="abstrakinggris">Soil salinity could significantly reduce rice yield, therefore, varieties tolerant to salinity are urgent to be developed. Mutation induction could be used to create rice mutants tolerant to salinity. The study aimed to evaluate the tolerance of somaclonal mutants of rice to NaCl salinity in a greenhouse condition and characterize their tolerance mechanism. A total of 45 putative mutants were generated by a gamma ray mutation induction followed with <em>in vitro</em> selection in the growth media containing different NaCl concentrations in the greenhouse experiment. The study consisted of two-factor treatments, namely three levels of NaCl concentrations and 45 rice mutants suspected to be tolerant to salinity, arranged in a completely randomized design. Proline, cations (K, Na, Ca, and Mg) content, and stomata density were evaluated.  The results showed that eight mutants were tolerant to 150 mM NaCl, namely CH30, CH-4-2, II-13-42, II-13-7, II-13-10, II-13-13, II-13- 2, and IA-3-21. These tolerant mutants had a higher Na content compared to the check parent. The tolerant mutants had a high proline content, lower Na, and stable K, Mg and Ca cations as well as had a greater number of stomata and higher stomata length-width ratio. Some of the identified tolerant mutants demonstrated the tolerant mechanism against salinity stress. Further studies are required to evaluate these tolerant mutants in the field conditions under salinity stress.</p>

O meloeiro tem grande importância econômica para o Nordeste brasileiro. Entretanto, em seu cultivo utiliza-se insumos que podem prejudicar o ambiente; como, os fertilizantes nitrogenados. Objetivou-se avaliar a emissão de N2O em cultivo de meloeiro amarelo ‘Goldex’. O experimento foi instalado em delineamento inteiramente casualizado, com cinco repetições. Os tratamentos foram: 0 (controle), 1,0; 1,5 e 2 vezes a quantidade de nitrogênio recomendada para cada estádio. Foi analisado o fluxo de N2O, área foliar, número de folhas, massa seca da parte aérea, massa seca dos frutos, massa seca da parte radicular, nitrogênio total do solo, das plantas e N (NH4+ e NO3-) do solo. O fluxo de N2O teve comportamento temporal irregular durante a fase de plântulas e crescente na floração. Os tratamentos afetaram significativamente a área foliar, número de folhas, massa seca da parte aérea, massa seca da parte radicular, nitrogênio da parte aérea e parte radicular das plantas e do solo. A aplicação de nitrogênio, em dosagens superiores à recomendada, não aumentou a produção do meloeiro. E o cálculo do fator de emissão mostrou que a emissão do N2O não atingiu valores prejudiciais ao ambiente.Palavras-chave: fator de emissão, efeito estufa e nitrogênio. NITROUS OXIDE EMISSION ASSOCIATED WITH UREA USE THE YELLOW MELON CROP ABSTRACT: The melon has great economic importance for the Brazilian Northeast. However, in its cultivation uses inputs that can harm the environment; Such as nitrogen fertilizers. The objective of this study was to evaluate the emission of N2O in yellow 'Goldex' cultivar. The experiment was installed in a completely randomized design with five replications. The treatments were: 0 (control), 1.0; 1.5 and 2 times the amount of nitrogen recommended for each stage. N2O flux, leaf area, leaf number, shoot dry mass, fruit dry mass, dry mass of the root portion, total soil nitrogen, of the plants and N (NH4 + and NO3 -) of the soil were analyzed. The flow of N2O had irregular temporal behavior during the seedling phase and increased in flowering. The treatments affected significantly the leaf area, number of leaves, dry mass of the aerial part, dry mass of the root part, nitrogen of the aerial part and root part of the plants and the soil. The application of nitrogen, in dosages higher than the recommended one, did not increase the production of the melon. And the calculation of the emission factor showed that the emission of N2O did not reach values harmful to the environment.Keywords: emission fator, greenhouse and nitrogen.

Yellow Passion Fruit

This study aimed to evaluate different substrates to produce yellow passion fruit seedlings. For this purpose, an experiment was carried out in a greenhouse, from April to June 2016. A completely randomized design with five replications, in a 6 x 5 factorial scheme was used. The first factor was the alternative substrates (poultry, cattle and equine manure, sugarcane and coconut bagasse, and Organomais compost). The second factor was the replacement levels to the commercial substrate of Plantmax® (100:0, 75:25, 50:50, 25:75, 0:100). The seedling evaluation was carried out 42 days after sowing. The following variables were analyzed: length, width, and the number of leaves; plant height and shoot dry matter. A significant effect (P0.05) for the interaction between the factors was verified. The addition of 60% cattle manure and Organomais to the commercial substrate Plantmax® promoted greater length, width, and the number of leaves, plant height, and shoot dry matter accumulation in the yellow passion fruit seedlings.

ABSTRACT Brazil is one of the world's largest producers of melon (Cucumis melo L.), and Rio Grande do Norte and Ceará are the largest producers states of the country (99% of exports). This crop had great socio- economic importance in the Brazilian Northeast, however, it is affected by insect pests and consequently, large amounts of pesticides are applied to it, which greatly affect beneficial organisms, such as Chrysopidae. This bioassay evaluated the toxicity of nine insecticides used in commercial crops of muskmelon, applied to first- instar larvae of Chrysoperla genanigra of up to 24-hour-old, from mass rearing cultures. Sublethal effects were evaluated, classifying the insecticides into the toxicity classes recommended by the IOBC. A completely randomized design was used, consisting of ten treatments (clothianidin, pymetrozine, lambda-cyhalothrin, chlorantraniliprole, indoxacarb, pyriproxyfen, beta-cyfluthrin+imidacloprid, imidacloprid, beta-cypermethrin and a control consisted of distilled water). The treatments consisted of exposure of thirty larvae to dry residues of each product in Petri dishes, assessing their mortality, duration of instars, sex ratio, fecundity and viability of eggs from adults of the insects evaluated. The products were classified in toxicity classes as harmful (Class 4) (clothianidin, pymetrozine, indoxacarb, lambda-cyhalothrin, beta-cyfluthrin+imidacloprid, imidacloprid, beta- cypermethrin and pyriproxyfen) and innocuous (Class 1) (chlorantraniliprole) to first -instar larvae of C. genanigra, by calculate their total effect. Based on this work, chlorantraniliprole is the only recommended insecticide for use in integrated pest management (IPM) programs in muskmelon crops.

ABSTRACT Teak (Tectona grandis) is a forest species cultivated in tropical regions worldwide, due to the traits of its wood and its great economic value on the market. In Brazil, original plantations are being replaced by selected clonal forests, which generate the need and interest to protect this genetic material based on the current legislation. The legal requirements for cultivar protection are that the genotype must result from genetic improvement and provide distinguishability, homogeneity, and stability (DHS). This work identifies morphological descriptors in teak cuttings to assist the clone protection process of the species. The study was conducted in a completely randomized design with the evaluation of 7 clones and 15 cuttings per clone, at 30, 60, 90, and 120 days old. The information was also organized based on the arrays of presence and absence of variations for each clone, for 21 morphological traits. Subsequently, genetic similarity measures were estimated using the Jaccard index and the UPGMA clustering method. The clones with the 12, 7, 9, and 11 morphological traits formed the morphological descriptors for the 30, 60, 90, and 120 days old cuttings, respectively. The traits of the leaf blade: length, width, length/width ratio, green intensity, and the brightness of the leaf, were common for all the evaluated ages, but their respective levels of expression were different.

Female Reproductive Organs

Fennel (Foeniculum vulgare Mill.) traditionally used by people as antifertility agent for female. Fennel leaves (Foeniculum vulgare Mill.) contain phytoestrogen that has role as antiestrogen or synthesized become antiestrogen. Coumarin is the kind phytoestrogen that can be antiestrogen to female reproductive organs such as ovary and utery. The aim of this research is to find out the influence of fennel leaves infuse (Foeniculum vulgare Mill.) on morphometric of ovary and utery in female rats (Rattus sp.) administered after parturition, to find out the effective dose  affecting the morphometric of ovary and utery and to find out the total coumarin consisted in fennel leaves (Foeniculum vulgare Mill.). This research was carried out by using CRD (Completely Randomized Design) consisted of 2 groups, those are control group (aquades) and treatment groups (doses of fennel leaves infuse 20 g/300 ml, 40 g/300 ml and 60 g/300 ml). The treatment was administered in the morning and afternoon for 15 days. After 15 days of treatment, the rats were sacrificed and dissected to measure the morphometry of reproductive organs (ovary and utery). The data obtained was analyzed by Analysis of Varian (ANOVA) and continued by LSD (Least Significance Different) test with significance of 5%. The measurement of coumarin level was performed by TLC (Thin Layer Chromatography) densitometry method. The result of this research showed that the administration of infused fennel leaves (Foeniculum vulgare Mill.) at dose of 20 g/300 ml, 40 g/300 ml and 60 g/300 ml significantly decreased ovarian weigh in female rats (Rattus sp.) after parturition (p<0,05), but not decreased the  length, width, thick of ovary, length and diameter of utery (p>0,05). No difference was observed between doses 20 g/300 ml, 40 g/300 ml and 60 g/300 ml, and it showed that the dose 20 g/300 ml of fennel leaves infuse was able to be used to decrease the weigth of ovary. Coumarin level observed in leaves is 0,09%, and it is higher than the coumarin content in fruit/seed.

The effect of different containers was evaluated to produce cocona seedlings (Solanum sessiliflorum) and jurubeba (Solanum paniculatum). The experiment was performed in the mesoregion of Alto Solimões, in Benjamin Constant, Amazonas state, Brazil, in a particular production area. The seeding was done in black holed polyethylene bags and polystyrene trays with 128, 200 and 288 cells with volumes of 250.00; 32.61; 21.60 and 9.88 cm³, respectively. We adopted a completely randomized design with four containers, four replicates, being assessed five plants per replicate. The seedlings of cocona were evaluated at 27, 38, 45 and 52 days after sowing (DAS) and of jurubeba at 38, 45, 52, 59 and 66 DAS. We evaluated the number of leaves; length of the main root, the aerial and total parts of the plant, fresh and dry matter of the main root, fresh and dry matter of the aerial part. There was no difference on the number of leaves of jurubeba at 45 and 66 DAS; there was no difference on the number of leaves of cocona at 52 DAS; there occurred a greater number of leaves of cocona when seeded on trays containing 200 cells; The other characteristics for both species presented higher values when the seeding was done in the plastic bags, at all evaluation dates.

Silage Production

In the western region of the State of Goias family farmers that depend onthe raising of livestock as one of their main sources of income are predominant. These farmers periodically grow maize for the production of silage in order to compensate their incomes. Considering the high cost of hybrid seeds and nitrogen fertilization, technologies that contribute to the reduction of silage production costs are required. In this sense, the objective of this study was to evaluate the response of maize genetic materials (Feroz Hybrid VIP3 and varieties SCS 156 and SCS 154), regarding silage production, bromatological composition and economic viability when inoculated with Azospirillum brasilense. The experiment was carried out on strips using a completely randomized design with four replications. Each cultivar responded differently to inoculation. For the Feroz hybrid and SCS 156 variety, the use of Azospirillum provided increases of 13.1% and 42.1% in green stem mass and 11.2 and 30.3% in silage nitrogen content, influencing the nutritional composition of the bulky food produced. For the SCS 154 variety, there was no response to inoculation. As for the economic viability, the use of inoculated SCS 156 variety presents a better rate of rentability, proving to be more economically attractive and viable to farmers.
