Freqüência de irrigação em meloeiro cultivado em solo arenoso

Abstract: RESUMO -O objetivo deste trabalho foi avaliar o efeito de cinco freqüências de irrigação na produtividade e na eficiência do uso da água em meloeiro cultivado sob fertirrigação por gotejamento em solo arenoso de Tabuleiro Costeiro do Piauí. O delineamento experimental foi em blocos ao acaso, com cinco tratamentos e seis repetições. Os tratamentos foram: F 1 , F 2 , F 3 , F 4 e F 5 , correspondentes às freqüências de irrigação de 0,5, 1, 2, 3 e 4 dias, respectivamente. A freqüência de irrigação influenciou as p… Show more

“…Confirming the assertion Fernandes and Prado (2004) reported that as little watermelon resistant to soil water deficit since the frequent irrigation throughout the growing season has significantly increased fruit production. Sousa et al (1999) point out that the high frequency of irrigation, besides increasing the efficiency of water use, favors the development of watermelon crop and thus enables greater productivity, since this practice tends to keep the soil in optimal moisture conditions.…”

“…Os valores de firmeza da polpa (FP) obtidos variaram de 4,45 a 17,51 N, estando próximos a os encontrado por Santos (2002) em híbridos Orange Flesh (15,65 e 15,66 N) e Galileo (6,74 e 5,32 N) submetidos a duas diferentes soluções nutritivas, aplicadas por meio da técnica do NFT (técnica do filme de nutrientes) e inferiores aos encontrados por Granjeiro (1999) que verificou em melão tipo amarelo na época da colheita valores de firmeza da polpa de 28,51 a 40,50 N. Os baixos valores de firmeza de polpa encontrados estão associados à característica da variedade estuda (melão tipo cantaloupe), apresentando baixa vida útil pós-colheita e menor resistência ao transporte, se comparada ao melão amarelo (SOUSA et al, 1999). DINUS & MACKEY (1974) afirmam que a firmeza da polpa do melão tipo cantaloupe é determinada largamente pelo tipo e qualidade de constituintes da parede celular, principalmente, o conteúdo de pectina solúvel e as estruturas das hemiceluloses.…”

“…The application of fertilizers via fertigation, normally by drip irrigation, can decrease the water and nutrient loss in the soil, enabling to adjust the quantity of nutrients applied to the needs of each development phase of the crop (GENUNCIO et al, 2010;CARDOSO and KLAR, 2012) and improve the efficiency of water use, nitrogen and other applied nutrients (VÁZQUEZ et al, 2006). It provides a decrease of the soil compaction (TEIXEIRA et al, 2007), presents generally a high uniformity of distribution of the fertilizer in field conditions, reduces manpower and enables greater parceling of the fertilizations, increasing, consequently, the efficiency on the utilization of fertilizers by the plants (DUENHAS et al, 2002;ELOI et al, 2007;SOUSA et al, 1999;HOU et al, 2009), though such results will only be achieved if the movements and reactions of the nutrients are well comprehended and managed (RAVIKUMAR et al, 2011).…”

“…The handling techniques of fertigation must always tend to the conservation and increment of the production capacity of the soils, aiming the elevation of productivity (SOUSA et al, 1999). Potential environmental problems are associated to the fertigation, standing out the contamination of the superficial sub-superficial water and by fertilizer leaching (CAUSAPÉ et al, 2004;DARWISH et al, 2011) and the accumulation of salts in more superficial soil layers (DIAS et al, 2005;FACTOR et al, 2008); such problems are normally associated to inadequate handling of the irrigation and to elevated doses of applied fertilizers .…”
