This study aimed to assess the effects of tree manures in comparison with NPK fertilizer on growth of Acacia senegal on the growth performance of Acacia senegal seedlings occurred in the following descending order: Azadirachta indica＞ Albizia lebbeck＞Khaya senegalensis＞NPK fertilizer. These results assert clearly the ameliorative and fertilizing characteristics of tree manures that can be reliably used for raising seedlings stocks in the nurseries.

“…This suggests that the stock type with older seedlings at planting grew slower in the nursery. The slow growth in the nursery can be partly attributed to the use of low-quality seeds, including genetic characteristics [46], which may have influenced the subsequent slow growth after planting.…”

“…The primary criterion was an initial RCD ≥ 7.3 mm (Figure 9), and the percentage of seedlings exceeding this criterion was 18%-30% for LIECO390 (0+1), JFA300.C (1+2), and HRO200 (1+1) but 0% for JFA300.E (1+2) and BCC150 (0+2) in container-grown stock types (Figure 4B, Table S1). For container-grown seedlings, the RCD of seedlings generally increases with large cell volume and low growing density of the container [54][55][56]; in Japanese larch, lower RCD was reported in JFA150 containers (cell volume: 150 mL, growing density: 292 cells m −2 ) with lower cell volume and higher seedling density compared to JFA300 containers (cell volume: 300 mL, growing density: 178 cells m −2 ) [57]. Thus, the low initial RCD of the BCC150 (0+2) can be attributed to the smallest cell volume and highest density of this container in the stock type of this study (Table 1).…”

It is important to understand the characteristics of Japanese larch (Larix kaempferi) seedlings that allow them to grow vigorously after planting and quickly exceed the height of surrounding vegetation, resulting in lower weeding costs. Seven stock types, including bareroot and container-grown seedlings, were planted in two plots with different mechanical-site-preparation (MSP) methods and evaluated for survival, height, and root collar diameter (RCD) for four consecutive years. Three-year-old bareroot seedlings, which were one year older and larger than normal, had low survival rates in the mulcher MSP. Initial seedling height significantly differed among the seven stock types, while almost no significant differences were observed after four growing seasons. Model analyses showed that initial seedling height and RCD had a significant effect on seedling height after planting until the second growing season, while the effect of planted seedling age and plot became increasingly significant after the third growing season. The difference in seedling type, bareroot versus container-grown seedlings, had no effect on the seedling height during the four growing seasons after planting. A decision tree analysis suggests that the seedlings with sufficiently large RCD and young age, regardless of seedling type, can grow taller than surrounding vegetation more quickly.

“…En el presente estudio, el agua de los viveros analizados estuvo fuera de diferentes parámetros recomendados para varias características en 4 a 85 %, mientras que para el norte de los Estados Unidos, solamente 1 % de los viveros que producen a raíz desnuda, manifestó problemas de calidad de agua, cifra que se elevó a 1 y 4.1 % cuando se trató de una tabla de agua muy alta y de disponibilidad del líquido (Landis 1984).…”

Diagnóstico de la calidad del agua en los viveros forestales de México Diagnosis of water quality of the forest nurseries in Mexico Introducción: Un vivero forestal debe contar con abundante provisión de agua de calidad. El agua de características deficientes puede contener sales, iones tóxicos, contaminantes o fitopatógenos. No obstante, en México la calidad del agua en dichos viveros ha recibido poca atención. Por ello, se planteó como objetivo realizar un diagnóstico de la calidad del agua en viveros forestales de México. Método: En 148 viveros forestales ubicados en la República Mexicana que producen planta en contenedor o en bolsa, fueron obtenidas muestras de 1 L de agua. Éstas se analizaron en el Laboratorio Central de la Universidad Autónoma Chapingo. Fueron estimados los parámetros de pH, conductividad eléctrica, concentración de bicarbonatos, calcio, boro, magnesio,sulfatos, sodio y cloro. Con los datos obtenidos se calculó la dureza total y la relación ajustada de adsorción de sodio (esta última para viveros que producen en bolsa).Resultados: Los parámetros que excedieron los límites establecidos fueron: pH con 84% (125 viveros), conductividad eléctrica con 34% (50 viveros), y concentración de bicarbonatos con 77% (114 viveros); en el resto de los parámetros medidos sólo un pequeño porcentaje está por arriba de los valores estándar. De todos los viveros, seis que producen en contenedor y dos que producen en bolsa, cumplen con los parámetros de calidad de agua, el resto tienen por lo menos un valor que no cumple con los límites establecidos.Conclusión: Con base en la proporción de viveros de cada región ecológica, la región templada sobresale con pH y bicarbonatos en altas concentraciones, y la región tropical húmeda presenta valores elevados en conductividad eléctrica. Se recomienda siempre seleccionar la ubicación del vivero entre otros factores, para contar con una fuente de agua de calidad.Palabras Clave: viveros forestales; calidad del agua; calidad de planta; producción de árbolesRecepción: 23-09-2015 Aceptación: 09-02-2016Diagnóstico de la calidad del agua en los viveros forestales de México Abstract Introduction: A forest nursery must be provided with abundant water of good quality water.The water with low quality may contain salts, toxic ions, pollutants or diseases. However, inMexico the quality of water in forest nurseries has received little attention in research.Because of that in this work is performed a diagnosis of the water quality in forest nurseries of Mexico. Method:In 148 containerized forest nurseries ubicated in Mexico, 1 L irrigation water samples were obteined. Such samples were analyzed in the Central laboratory of the Universidad Autónoma Chapingo. From the samples were determined the parameters pH, electric conductivity, concentration of bicarbonates, Ca, B, Mg, sulfates, Na and Cl. With the obtained data was calculated the total hardiness and the adjusted sodium adsorption ratio (this last for nurseries that produce the trees in plastic bags). . Results:The parameters that e...
