Fuentes y dosis de materias orgánicas en la materia seca del Maíz (Zea mays L.) en invernadero - UNALM

Abstract

El presente ensayo se realizó en el Laboratorio e invernadero de Fertilidad de Suelos perteneciente a la Facultad de Agronomía, ubicado en la Universidad Nacional Agraria La Molina. Se evaluó el efecto de la aplicación de niveles de fertilización (0-0-0) y 150 N - 150 P2O - 150 K2O, con fuentes de materia orgánica al 1%: Gallinaza 1er uso, Gallinaza 3er uso, Gallinaza 6to uso, Compost Molido, Compost sin Moler, Koripacha y vermicompost, en un suelo arenoso, también se incluyó en el experimento tratamientos adicionales y con utilizando fertilizantes minerales, 150 N - 150 P2O - 150 K2O, usando los fertilizantes: urea, superfosfato triple de calcio y cloruro de potasio. Las variable analizadas fueron altura de planta, materia seca total, extracción total de nitrógeno, fósforo y potasio, utilizando el maíz PM-213 como cultivo indicador. Se utilizó un arreglo factorial de 7x2 con tres repeticiones en un Diseño Completamente al Azar (DCA). Los resultados del estudio demostraron que la mayor altura, materia seca total y extracción total de nitrógeno lo presento gallinaza 1er uso, para la extracción total de fósforo y potasio lo obtuvieron gallinaza 6to uso y gallinaza 3er uso respectivamente. En los resultados analizados; existen diferencias significativas entre los niveles (1% y 2%), finalmente en la extracción total de nitrógeno, potasio y fósforo, las tratamientos más extractivas son compost sin moler, Gallinaza 3er uso y Gallinaza 6to uso o Compost sin moler, respectivamente.

This trial was conducted in the laboratory and greenhouse Soil Fertility belonging to the Faculty of Agriculture, located at the Universidad National Agrarian La Molina. The effect of the application of seven sources of organic matter was evaluatedThe present essay was carried out in the Laboratory and greenhouse of Fertility of Soils belonging to the Faculty of Agronomy, located in the National Agrarian University La Molina. The effect of application of fertilizing levels (0-0-0) and 150 N - 150 P2O - 150 K2O, with sources of organic matter at 1% was evaluated: Gallinaza 1st use, Gallinaza 3rd use, Gallinaza 6to use, Compost In addition, additional treatments were also included in the experiment and using mineral fertilizers, 150 N - 150 P2O - 150 K2O, using fertilizers: urea, triple calcium superphosphate And Potassium Chloride. The variables analyzed were plant height, total dry matter, and total extraction of nitrogen, phosphorus and potassium, using maize PM213 as indicator culture. A 7x2 factorial arrangement with three replicates was used in a Completely Random Design (DCA). The results of the study showed that the highest height, total dry matter and total nitrogen extraction were presented by first use poultry, for the total extraction of phosphorus and potassium were obtained henna 6th use and henna 3er use respectively. In the analyzed results; there are significant differences between the levels (1% and 2%), finally in the total extraction of nitrogen, potassium and phosphorus, the most extractive treatments are compost without grinding, henry 3er use and henry 6th compost or ungrounded compost, respectively
