Growing of coffee seedlings on different substrates and fertilized with lithothamium

Resumo

The coffee seedling production quality is essential to ensure crop development in field. Thus, the objective of this study was to evaluate the effect of two substrates (cattle manure and filter cake) interacting with four levels of organic fertilizer with lithothanmium in coffee seedlings var. Lempira production. A completely randomized experimental design was used with factorial arrangement of treatments 5 x 2, five levels of lithothamnium (0, 1.75, 3.50, 5.25, and 7 kg m-3 of substrate), two substrates (cattle manure and filter cake) and three replicates. The variables evaluated were: plant height, number of leaves, stem diameter, and root length. The treatments produced significant effects on the initial development parameters of the coffee seedlings. The best results in plants grown were obtained in cattle manure substrate with 5.25 kg m-3 of lithothamnium, and decreased with levels higher than 1.75 kg m-3 of lithothanmium in filter cake substrate.
La producción de plantas vigorosas constituye un requisito indispensable para garantizar el desarrollo de los cultivos en el campo definitivo. Así, el presente trabajo tuvo como objetivo evaluar el efecto de dos sustratos (estiércol de corral y torta de filtro) y cuatro dosis de fertilizante orgÔnico con lithothanmium en la producción de plÔntulas de café var. Lempira. Se utilizó un diseño experimental completamente al azar con arreglo factorial de los tratamientos 5 x 2: 5 doses de lithothanmium (0, 1,75, 3,50, 5,25 y 7 kg m-3 de sustrato), dos sustratos (estiércol de corral y torta de filtro) y tres repeticiones. Las variables evaluadas fueron: altura de la planta, número de hojas, diÔmetro de tallo y crecimento de raíz. Los tratamientos produjeron efectos significativos en los parÔmetros de desarrollo inicial de las plÔntulas de café. Los mejores resultados en plantas cultivadas se obtuvieron en el sustrato de estiércol con 5,25 kg m-3 de lithothamnium y disminuyeron con dosis superiores a 1,75 kg m-3 de lithothamnium en sustrato de torta de filtro.
