Resumo: The south of the state of Roraima is a region where there is a predominance of small farmers, most of whom are without capital. The use of organic compounds is an alternative to reduce costs through nutrient cycling. The use of organic waste available in the region, mainly sawdust from sawmills, can be an alternative for the production of compounds. Given this, the objective was to produce organic compounds using sawdust (SD) and sheep manure (EM) in different proportions and to evaluate the production of pumpkin culture when fertilized with the compounds in a sandy soil. The work was developed in two stages: the first the production of organic compounds and the second the evaluation of the production of the pumpkin culture. Two compounds were produced with different proportions of SD and EM. To evaluate the production of pumpkin culture, the following treatments were used: 1. cultivation without fertilization (control); 2. compound 1 (C1) (50% SD + 50% EM); 3. compound 2 (C2) (75% SD + 25% EM); 4. EM; 5. biofertilizer (Bio) and 6. mineral fertilization (N-P-K). It was observed that C1 started and ended with a lower C/N ratio than C2. The temperature (ºC), humidity and pH differ little between the compounds. Regarding the productivity of the pumpkin culture, the treatments EM, C1 and C2 were the ones that produced the most, however, C1 and C2 did not differ from mineral fertilization. It was concluded, therefore, that organic compounds can be used to replace mineral fertilizer.

El uso de compuestos orgánicos es una alternativa para reducir costos mediante el ciclo de nutrientes. El aprovechamiento de residuos orgánicos disponibles en la región, principalmente aserrín de aserraderos, puede ser una alternativa para la producción de compuestos. Ante esto, el objetivo fue producir compuestos orgánicos utilizando aserrín (AS) y estiércol de ovino (EO) en diferentes proporciones y evaluar la producción de cultivo de calabaza cuando se fertiliza con los compuestos en un suelo arenoso. El trabajo se desarrolló en dos etapas: la primera la producción de compuestos orgánicos y la segunda la evaluación de la producción del cultivo de calabaza. Se produjeron dos compuestos con diferentes proporciones de AS y EO. Para evaluar la producción de cultivo de calabaza se utilizaron los siguientes tratamientos: 1. cultivo sin fertilización (testigo); 2. compuesto 1 (C1) (50% AS + 50% EO); 3. compuesto 2 (C2) (75% AS + 25% EO); 4. EO; 5. biofertilizante (Bio) y 6. fertilización mineral (N-P-K). Se observó que C1 comenzó y terminó con una relación C/N más baja que C2. La temperatura (ºC), la humedad y el pH difieren poco entre los compuestos. En cuanto a la productividad del cultivo de calabaza, los tratamientos EO, C1 y C2 fueron los que más produjeron, sin embargo, C1 y C2 no difirieron de la fertilización mineral. Por lo tanto, se concluyó que los compuestos orgánicos pueden usarse para reemplazar los fertilizantes minerales.O sul do estado de Roraima é uma região onde há predominância de pequenos agricultores, em sua maioria descapitalizados. A utilização de compostos orgânicos é uma alternativa para reduzir custos através da ciclagem de nutrientes. O uso dos resíduos orgânicos disponíveis na região, principalmente a serragem das serrarias, pode ser uma alternativa para produção de compostos. Diante disto, objetivou-se produzir compostos orgânicos utilizando serragem (SE) e esterco de ovino (EO) em diferentes proporções avaliando a produção da cultura da abóbora quando fertilizada com os compostos em um solo arenoso. O trabalho foi desenvolvido em duas etapas: sendo a primeira a produção dos compostos orgânicos e a segunda a avaliação da produção da cultura da abóbora. Foram produzidos dois compostos com diferentes proporções de SE e EO. Para avaliação da produção da cultura da abóbora, utilizaram-se os seguintes tratamentos: 1. cultivo sem adubação (testemunha); 2. composto 1 (C1) (50%SE + 50%EO); 3. composto 2 (C2) (75%SE + 25%EO); 4. EO; 5. biofertilizante (Bio) e 6. adubação mineral (NPK). observou-se que o C1 iniciou e finalizou com menor relação C/N do que o C2. A temperatura (ºC), umidade e pH se diferenciam pouco entre os compostos. Em relação à produtividade da cultura da abóbora, os tratamentos EO, C1 e C2 foram os que mais produziram, no entanto, C1 e C2 não se diferenciaram da adubação mineral. Concluiu-se, portanto, que os compostos orgânicos podem ser utilizados em substituição ao fertilizante mineral.Research, Society and Development2020-11-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/951010.33448/rsd-v9i11.9510Research, Society and Development; Vol. 9 No. 11; e929119510Research, Society and Development; Vol. 9 Núm. 11; e929119510Research, Society and Development; v. 9 n. 11; e9291195102525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/9510/8564Copyright (c) 2020 Hipólito Ribas Pereira; Romildo Nicolau Alves; Josimar da Silva Chaves; Sandoval Menezes de Matos; João Pedro Santos do Nascimento; Ronielly Barbosa Soares; Lucas Souza da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPereira, Hipólito Ribas Alves, Romildo Nicolau Chaves, Josimar da SilvaMatos, Sandoval Menezes de Nascimento, João Pedro Santos do Soares, Ronielly Barbosa Silva, Lucas Souza da 2020-12-10T23:37:57Zoai:ojs.pkp.sfu.ca:article/9510Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:31:46.469713Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
