Akinrinde E.A. 3 2007 1 3 This study was conducted to determine the effect of propagule weight and nitrogen fertilizer rates on growth and yield of pineapple in southwestern Nigeria. Pineapple whole stump were collected from the Teaching and Research Farm, University of Ado-Ekiti which were split into three different weights viz: Short Weight (SW), Medium Weight (MW) and Large Weight (LW). Nitrogen fertilizer was applied at 0, 100, 150 and 200 kg N ha-1. Treatments were arranged in a split plot design with propagule weight as the main plot factor and N rates as sub-plot factor. The results indicated a significant (p<0.05) increase in length of D leaf, number of leaves, root length and days to 50% sprouting. Optimum fruit yield 210.03 MT ha-1 was obtained at 150 kg N ha-1. Large weight propagules gave significant increase in yield and yield components except fruit weight, fruit diameter and fruit length which were not significant.
