Resumo: | The objective of this work was to evaluate the effect of five irrigation frequencies in the productivity and efficience of water use of melon crop cultivated under fertirrigation by drip irrigation in a sandy soil of the Coast Plains of Piauí, Brazil. The experiment was allocated in a randomized complete block design, with five treatments and six replications. The treatments were: F1, F2, F3, F4 and F5, irrigation frequency of 0.5, 1, 2, 3 and 4 days, respectively. The irrigation frequency affected the marketable and total yield of the melon crop. The highest total (70.73 t ha-1; 77.99 t ha-1 and 64.21 t ha-1) and marketable (62.20 t ha-1; 63.88 t ha-1 and 53.67 t ha-1) yields were obtained with the frequencies of 0.5 and 1 day, respectively. It was observed that for the leastest frequent of water applications there was a significative reduction (P < 0.01) of the marketable and total fruit yield of melon crop. The average fruit weight was not affected by the frequency of water application. The highest and the lowest efficiency of water use, 24.40 kg m-3 and 14.14 kg m-3, were obtained with the frequencies of F1 and F5, respectively. The irrigation frequency twice a day, daily and two days are indicated for melon crop cultivated in sand soil by drip irrigation. The efficiency of water use for the melon crop is higher when the irrigation frequencies are higher. |

O delineamento experimental foi em blocos ao acaso, com cinco tratamentos e seis repetições. Os tratamentos foram: F1, F2, F3, F4 e F5, correspondentes às freqüências de irrigação de 0,5, 1, 2, 3 e 4 dias, respectivamente. A freqüência de irrigação influenciou as produtividades comercial e total do meloeiro. As maiores produtividades totais (70,73 t ha-1; 77,99 t ha-1 e 64,21 t ha-1) e comerciais (67,20 t ha-1; 63,88 t ha-1 e 53,67 t ha-1) foram obtidas com as freqüências de 0,5 e de 1 dia, respectivamente. Com aplicações menos freqüentes, houve redução significativa (P < 0,01) nas produtividades comercial e total do meloeiro. O peso médio de frutos não foi influenciado pelas freqüências de aplicação de água. A maior e a menor eficiência de uso de água, 24,40 kg m-3 e 14,14 kg m-3, foram obtidas com F1 e F5, respectivamente. As freqüências de irrigação de duas vezes por dia, diária e a cada dois dias, são as recomendadas para o meloeiro cultivado em solo arenoso sob fertirrigação por gotejamento. A eficiência de uso da água no meloeiro é maior quando as freqüências de irrigação são maiores.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirade Sousa, Valdemício FerreiraCoêlho, Eugênio Ferreirade Sousa, Valdomiro Aurélio Barbosa1999-04-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5201Pesquisa Agropecuaria Brasileira; v.34, n.4, abr. 1999; 659-664Pesquisa Agropecuária Brasileira; v.34, n.4, abr. 1999; 659-6641678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5201/2393info:eu-repo/semantics/openAccess2010-07-06T11:32:27Zoai:ojs.seer.sct.embrapa.br:article/5201Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-06T11:32:27Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
