The tomato crop is very demanding in water, its water demand requires an irrigation practice to obtain an optimum dry crop production in the season. Through the technology of economic channels, it is possible to save water in tomato production through subsurface irrigation. The objective is to evaluate the growth and production of tomato under different irrigation depths in the economic channels with mulching, applying or increasing in family farming. The experiment was conducted in the factorial scheme (5 x 2) x 4, with subdivided plots, in the DBC, without which was the effect of 5 irrigation depths (50%, 75%, 100%, 125% and 150% of ETc) on two tomato cultivars: RIO GRANDE (Lycopersicon lycopersicum) and CALINE IPA-7 (Lycopersicones culentum Mill.), arranged in four replications. The EVALUATED characteristics were: plant diameter (DC); Plant height (H); number of leaves (NF); lateral branches (NR); number of floral branches (NRFL); weight per fruit (P / F); average fruit diameter (DIA); volume (VOL); density (DS); production (PROD) and productivity (PRODT) and water use efficiency. An IPA7 cultivar does not differ statistically in terms of water use, showing that it is possible to produce tomatoes with low water consumption and 75% undifferentiated production and use when compared to a standard that obtains, therefore, a saving of 25% of (100 % Etc). According to these results, the applied technology of economic beds with mulching is ideal for saving water in food production aiming at water use efficiency in family farming.Item Rendimento produtivo do rabanete cultivado sob diferentes lâminas de irrigação e qualidades de adubação(2019) Sá, Carlos André de Souza; Nascimento, Antônio Henrique Cardoso do; http://lattes.cnpq.br/5216997634308364; http://lattes.cnpq.br/3285445362250128Water stress along the radish crop cycle may interfere with its development, causing changes in morphology, interfering with the biochemical reactions of the plant. The objective of this work was to evaluate the productive yield of radish (Raphanus sativus L.) cultivated under different irrigation depths and fertilization qualities, from September to December 2019, in the Serra Talhada Academic Unit - UFRPE/UAST. The design adopted was in a factorial scheme (5 x 3) x 4 consisting of five irrigation depths (50, 75, 100, 125 and 150% of The ETc), three sources of fertilization (two organic sources and one mineral source as control treatment) and four replications, in randomized blocks with arrangement of subdivided plots. Campaigns were carried out to obtain biometric and biomass data. Of the biometric parameters, the following parameters were analyzed: shoot height, number of leaves, plant weight, commercial diameter, root system length and root weight. Biomass was performed to determine the efficiency of water use. The irrigation depth of 113.2% of the ETc provided higher production of the commercial part of the radish. It was found that the efficiency of water use is maximized with the use of smaller irrigation depths. It is feasible to partially or fully replace mineral fertilization with organic fertilization for the production of radish.Item Estruturas hidráulicas e eficiência da aplicação de água cinza em áreas irrigadas por pequenos produtores rurais do Sertão do Pajeú e do Sertão do Araripe(2019) Silva, Paulo Romário Calixto da; Barros Júnior, Genival; http://lattes.cnpq.br/4379675294862211; http://lattes.cnpq.br/9400875516238976Item Avaliação de métodos de estimativa da evapotranspiração de referência para a região do vale do São Francisco(2019) Silva, Maiara Tatiane Lima; Souza, Luciana Sandra Bastos de; http://lattes.cnpq.br/1186468548787818; http://lattes.cnpq.br/8455026363821368Information related to reference evapotranspiration (ET0) is very important for irrigation management, especially in regions dependent on agriculture. To determine it several methods can be used, among which are the alternative methods, which are used of few data. This work hypothesized that new models for estimating evapotranspiration and those developed locally better represent ET0 of the Submedio São Francisco. In order to investigate the adequacy of historical and contemporary models for the estimation of ET0 and to develop a new method for its estimation in the region of the Vale do São Francisco. The work was carried out in Juazeiro, Ba, using data referring to a meteorological station belonging to EMBRAPA Semiarid, using data of temperature, relative humidity, wind speed, precipitation and global solar radiation, for the year 2017 and 2018, and for validation of the poposed odel, data from 2016. The data were used in the determination of evapotranspiration using the Penman-Monteith methods and the alternative ones, subdivided into two groups: historical,those developed before theyear 2000with the methods of Hargreaves-Samani, Camargo, Jensen-Haise, Makkink, Solar radiation FAO 24 and Benevides-Lopes, and contemporary, developed afterthe year 2000, with Irmak, Castaneda-Rao, Moretti-Jerszurki-Silva, Silva-Souza, additionally, the information was used in the development of a simple model for ET0 estimation. This information was compared using the indices for which Pearson's correlation coefficient (r), coefficient of determination (r²) and Willmont's concordance index were considered. Based on these results, it was possible to observe that contemporary methods, with the exception of Moretti-Jerszurki-Silva, tended to reduce errors in the estimation of reference evapotranspiration.The most appropriate method to estimate ET0 was the FAO-24 Solar Radiation. The alternative model obtained in the present work was based only on temperature and humidity data and was classified as very good.
