ÁGUA SALINA E SUBSTRATOS NO CRESCIMENTO INICIAL DO MELOEIRO   MARIA ÂNGELA CASIMIRO LOPES1; RAFAEL VITOR DA SILVEIRA MUNIZ1; SAMARA SIBELLE VIEIRA ALVES2; ALINE COSTA FERREIRA1; FRANCISCO VANIES DA SILVA SÁ3 E LUDERLÂNDIO DE ANDRADE SILVA3 1 Unidade Acadêmica de Ciências Agrárias, Universidade Federal de Campina Grande, UFCG, Pombal, PB, Brasil, [email protected], [email protected], [email protected] Unidade Acadêmica de Garanhuns, Universidade Federal Rural do Pernambuco, UFRPE, Garanhuns, PE, Brasil, [email protected] Centro de Ciências e Recursos Naturais, Universidade Federal de Campina Grande, UFCG, Campina Grande, PB, Brasil, [email protected], [email protected]  1 RESUMO Objetivou-se estudar a produção de mudas de meloeiro em função de diferentes substratos irrigados com água salina. O experimento foi desenvolvido em casa de vegetação no município de Pombal, Paraíba PB, no período de abril a maio de 2015. Adotou-se o delineamento experimental inteiramente casualizado, em esquema fatorial 4 x 3 x 2 constituído de quatro níveis de salinidade da água de irrigação - CEa (0,3; 1,5; 3,0 e 4,5 dS m-1) e três substratos [S1= solo; S2= solo + composto orgânico (2:1); e S3 = solo + esterco bovino (2:1)], e duas variedades de melão (V1= Melão Gaúcho Casca de Carvalho; V2= Hales Best Jumbo), com quatro repetições e três plantas úteis por repetição. As plantas foram conduzidas em recipientes com capacidade de 0,5 dm3 durante 32 dias após a semeadura, quando foram avaliadas quanto ao crescimento e acúmulo de matéria seca. O crescimento e o acúmulo de matéria seca de ambas as variedades foram reduzidos com o aumento da salinidade da água de irrigação. O crescimento e acúmulo de massa seca da variedade Hales Best Jumbo no substrato constituído de solo com composto orgânico foi menos afetado pelo estresse salino. A variedade Gaúcho Casca de Carvalho é a mais sensível ao estresse salino independente do substrato utilizado. Palavras-chave: Cucumis melo L.; estresse salino, composto orgânico.  LOPES, M. A.

A.SALINE WATER AND SUBSTRATES ON INITIAL GROWTH IN MELON  2 ABSTRACT The aim was to study the production of melon seedlings for different substrates irrigated with saline water. The experiment was conducted in a greenhouse in the city of Pombal, Paraíba, PB, in the period April-May 2015. We adopted a completely randomized design in a factorial 4 x 3 x 2 design, consisting of four levels of irrigation water salinity (0.3, 1.5, 3.0 and 4.5 dS m-1) and three substrates [S1= ground; S2= soil + organic compound (2:1); and S3= soil + manure (2:1)] , and two varieties of melon (V1 = Gaúcho Casca de Carvalho; V2 = Hales Best Jumbo), with four replications and three plants per repetition. Plants were kept in containers with a capacity of 0.5 dm3 for 32 days after sowing, when they were evaluated for growth and accumulation of dry matter. Growth and dry matter accumulation of both varieties were reduced with increasing irrigation water salinity. The growth and accumulation of dry mass of the Hales Best Jumbo variety in the substrate composed of soil with organic compost was less affected by salt stress. The Gaúcho Casca de Carvalho variety is the most sensitive to salt stress regardless of the substrate used. Keywords: Cucumis melo L., salt stress, organic compound

Irrigation Waters

The effects of boron and effluent (treated sewage water) on vegetative growth, fruit yield, and boron uptake of grafted and nongrafted melons (Cucumis melo L. cv. Arava) were studied. Nongrafted melon plants and melon plants grafted onto the commercial Cucurbita maxima Duchesne × Cucurbita moschata Duchesne rootstock ‘TZ-148’ were grown in pots filled with perlite in a heated greenhouse and were irrigated with fresh water or effluent. The two irrigation waters contained boron in five concentrations ranging from 0.1 to 10.4 mg·L−1. The boron concentration in the plants increased linearly with that in the irrigation water. The highest boron concentrations were found in old leaves, the lowest in the fruit, and intermediate concentrations were noted in the roots. The boron concentrations were, in general, significantly lower in grafted than nongrafted plants, possibly because the root system of the former had higher selectivity and lower boron absorption than that of the latter. Fruit yield and dry weight accumulation in shoots and roots decreased linearly as the boron concentration in the irrigation water increased, the nongrafted plants were more sensitive than grafted ones to the boron level, and both were more sensitive under fresh water irrigation than under effluent irrigation. It is suggested that the higher boron sensitivity of the root systems of the nongrafted plants probably decreased their capability to absorb water and nutrients, which in turn sharply reduced their fruit yields.

QUALIDADE FÍSICA E QUÍMICA DE FRUTOS DE MELOEIRO RENDILHADO CULTIVADO SOB DIFERENTES ÉPOCAS DE APLICAÇÃO DE CO2 VIA ÁGUA DE IRRIGAÇÃO.  Boanerges S. D’ Albuquerque Júnior1; José Antonio Frizzone1; Sergio Nascimento Duarte1; Rafael Mingoti1; Nildo da Silva Dias2; Valdemício Ferreira de Sousa21Departamento de Engenharia Rural, Escola Superior de Agricultura Luiz de Queiroz, Universidade de São Paulo, Piracicaba, SP,  [email protected] Meio-Norte, Teresina, PI 1 RESUMO O melão tem se constituído em ótimo negócio para o Nordeste brasileiro. O Brasil passou a se destacar no cenário internacional, embora com registros de quedas nas exportações nos últimos anos. Sabe-se que nos últimos 100 anos a concentração de CO2 na atmosfera vem aumentando. Pensando no que isso poderia representar para as plantas, nas últimas décadas se intensificaram os estudos com aplicação de CO2 nas plantas via ambiente e via água.  Freqüentemente foram observados aumentos em crescimento de produção  sob elevadas  concentrações de CO2 na atmosférica.  Têm sido freqüentes os estudos com dióxido de carbono (CO2) na cultura do meloeiro com o intuito de tornar viável a relação custo/benefício, de modo a se tentar reduzir o número de aplicações e o volume de CO2 aplicado por área cultivada, porém mantendo a produtividade quando se aplica o CO2 durante todo o ciclo. O objetivo deste trabalho foi estudar o efeito de uma dose de CO2 aplicada em diferentes fases fenológicas da cultura do melão via água de irrigação por gotejamento subsuperficial sobre a qualidade pós-colheita de frutos de meloeiro rendilhado cultivado em ambiente protegido. Os resultados mostram que a aplicação de CO2 não alterou a qualidade dos frutos (Brix e pH), porém no tratamento 3 se observou uma menor acidez. A aplicação de CO2 via água de irrigação nos períodos de frutificação (T3) e do florescimento (T1) proporcionaram aumentos na produção de melão em relação ao tratamento sem CO2 (T4), respectivamente; verificou-se um menor incremento do T2 em relação ao T4. UNITERMOS: pós-colheita, subsuperficial, Cucumis melo L.  D’ ALBUQUERQUE JÚNIOR, B.

PHYSICAL AND CHEMICAL QUALITY OF MELON FRUITS UNDER DIFFERENT SET OF CO2 APPLICATION THROUGH IRRIGATION WATER    2 ABSTRACT Melon is turning into a big business for the northeast of Brazilthat starts to stand out in the international scenery, although there has been a decrease in exportation in the last years.  It is known that in the last 100 years the concentration of CO2 in the atmosphere is increasing. Thinking about what that could represent for plants, in the last decades studies of CO2 application in plants through atmosphere and water have been intensified.  Increases were frequently observed in production growth under high CO2 concentrations in the atmosphere.  Studies with CO2  have become usual in melon production in order to make the cost/benefit relation viable, and to try to reduce the number of CO2 applications and volume per cultivated area, but keeping productivity when CO2  is applied during the whole cycle. The objective of this work was to study the effect of one single CO2 rate, applied at different crop stages through water by a subsurface drip irrigation system, under post harvest quality in net melon fruits cultivated in greenhouse. Results showed that CO2 application did not alter fruit quality (Brix and pH), but treatment 3 resulted in  smaller acidity. Obtained data showed that CO2 application through irrigation water for the fruiting (T3) and flowering (T1) treatments provided yield increases, respectively,  when compared to untreated (T4); the lowest yield increment was obtained by flowering plus fruiting T2  when compared to T4. KEYWORDS: post harvest, dripping, Cucumis melo L.

At the stage of water treatment for irrigation systems, the efficiency capture coarse and fine mechanical impurities, as well as oil products and organic compounds affects the reliability of the equipment of the irrigation network and the safety of energy exchange processes in irrigated agricultural landscapes. The violation of work irrigation system can cause disruptions in irrigation schedules of agricultural crops, crop shortages, degradation phenomena on the soil and ecological tension. For the combined irrigation system, a water treatment unit has been developed, representing a hydrocyclone apparatus with a pipe filter in the case. For the capacity of 250 m3/h the main geometrical dimensions of hydrocyclone have been calculated. To organize the capture petroleum products and organic compounds, it has been proposed a modernization of a hydrocyclone unit, consisting in dividing the cylindrical part of the apparatus into two section. The first is section is for input irrigation water, the second one is for additional drainage of clarified irrigation water after sorption purification by the filter, placed on the disk and installed coaxially with the drain pipe and the pipe filter.
