Summary: | The ground cover is an agricultural practice that is designed mainly to control weeds, while the nonwoven prevents the attack of pests. The objective of this study was to evaluate the yield and fruit quality of watermelon grown under nonwoven textile protection combined with plastic mulching. The experiment was conducted at the WG Fruits Company, Barauna, RN. A randomized block design was used in a factorial 3 x 3 + 1 with four replications, and 36 plants per plot, with the first factor of color of plastic used in mulching (black, silver and white) and the second factor nonwoven textile with different times of use (first and third crop nonwoven under textile and without nonwoven) and an absolute control (no mulching and without nonwoven). The production variables evaluated were: yield (commercial, noncommercial, and total fruit yield), and fruit quality (soluble solids--SS, titratable acidity--TA and SS/TA). The use of mulching and protection of plants with nonwoven textile provided a higher yield of watermelon fruits in relation to bare soil with and without nonwoven textile protection. Fruit quality was not affected by the use of mulching and nonwoven.

O objetivo deste trabalho foi avaliar o rendimento e a qualidade dos frutos da melancia cultivada sob protecao de agrotextil combinado com mulching plastico. O experimento foi realizado na empresa WG Fruticultura, Barauna, RN. Utilizou-se o delineamento em blocos ao acaso em esquema fatorial 3 x 3 + 1 com quatro repeticoes e 36 plantas por parcela sendo o primeiro fator composto por cores de mulching plastico (preto, prata e branco) e o segundo fator por agrotextil com diferentes tempos de uso (agrotextil de primeiro e terceiro cultivos e sem agrotextil) e testemunha absoluta (sem mulching e sem agrotextil). Analisaram-se as variaveis de producao (produtividade de frutos comerciais, produtividade nao comercial e produtividade total) e a qualidade dos frutos (solidos soluveis--SS, acidez titulavel--AT, relacao SS/AT). O uso do mulching e da protecao das plantas com agrotextil, independente do tempo de uso, proporcionou maior rendimento de frutos de melancia em relacao ao solo descoberto e sem a protecao com agrotextil. A qualidade dos frutos nao foi afetada pelo uso do mulching e do agr |
