[Unpublished Undergraduate Feasibility Study, Don Mariano Marcos Memorial State University - North La Union Campus, Sapilang, Bacnotan, La Union]. Lakasa ti Sirib, DMMMSU Institutional Repository.https://lakasa.dmmmsu.edu.ph/handle/123456789/2090This study was conducted to determine the effects of potting media, leaf pruning and the interaction between potting media and leaf pruning on the growth and survival of rambutan wildlings. It was conducted at the Agroforestry Nursery of the Institute of Agroforestry and Watershed Management, DMMMSU-NLUC, Bacnotan, La Union, from January 18, 2013 to April 18, 2013. Three hundred sixty wildlings of rambutan were used in the study and were laid out using two-factor (3x4) experiment in Completely Randomized Design (CRD) with 12 treatment combinations replicated three times. The different treatments used were the following Factor A - (Potting media) P₀ – ordinary garden soil (control) P₁ – forest top soil ordinary garden soil, and river sand (1:1:1) P₂ – vermicompost, ordinary garden soil, and river sand (1:1:1) Factor B (Leaf pruning) L₀ – No leaf pruning L₁ – ½ of the size of the leaflets were pruned L₂ – ¼ of the size of the leaflets were pruned L₃ – ¾ of the size of the leaflets were pruned The study revealed highly significant results on the length of primary roots of rambutan wildlings as affected by potting media, length of primary roots as affected by potting media, leaf pruning and the interaction of potting media and leaf pruning, and on the shoot-root ratio as affected by potting media and the interaction of potting media and leaf pruning. The analysis revealed significant results on the weight of roots as affected by potting media. However, all other parameters taken have comparable results. The rambutan wildlings that were planted to ordinary garden soil and the wildlings that were pruned ¼ of the size of its leaflets gained low shoot-root ratio.en-USThesis
