Planting of Seedlings and Direct Seeding with Different Inputs in Pioneer Species in the Southeastern Amazon

Abstract: The main objectives of the study were to determine which was the best implantation of forest method between direct seeding and planting of seedlings, the use of Slow Release Fertilizer (SRF) and hydrogel in the pioneer species Schizolobium parahyba var. amazonicum and Senegalia polyphylla, and the use of morphometric indices, such as slenderness of trunk and canopy, to assist in growth evaluation. Generalized Linear Model (GLM) and Principal Component Analysis (PCA) were used as the main methods. The morphomet… Show more

“…We expected that the survival and relative growth rates of DS would be higher than those of SP, due to their germination in their definitive location, and not suffering the stress of transplanting from the nursery to the field (Raman et al 2009; Silva & Vieira 2017; Fagundes et al 2018). However, planted seedlings are older and larger in terms of biomass and height at the moment they are transferred into the field (Atondo‐Bueno et al 2018; Scaloppi & de Souza 2020; Silva et al 2020), and that is why we expected them to be taller by the end of the study. Moreover, we compared total cost per planting hole, per surviving tree, and the ecological and economic performance of SP and DS, seeking to recommend the most effective strategy.…”

“…Dentro de las prácticas que influyen de manera directa en la restauración del bosque podemos considerar aquellas de carácter pasivo (i.e auto resiliencia) y aquellas prácticas activas que implican la siembra de semillas o la plantación de individuos en el bosque (Campoe et al, 2014;Ceccon et al, 2016). El enriquecimiento de bosques degradados mediante la plantación de individuos producidos en vivero tiene la ventaja de poder elegir y 'rustificar' las especies con las que se enriquecerá el bosque (Silva et al, 2020).…”
