ABSTRACT:A field experiment was carried out at Botswana College of Agriculture content farm, Sebele about 10 km
from the center of Gaborone city to evaluate the effect of different application rates of organic fertilizer on growth,
development and yield of rape from November 2014 to March 2015. The experiment was laid out in a complete
randomized block design (RCBD) with four different application rates of organic fertilizer being 0, 5, 7.5 and 10 kg m-2
each replicated three times. Plant parameters measured were; plant height, leaf number, leaf area and leaf fresh weight.
For plant height and number of leaves a non-significant treatment effect was observed for the first 7 weeks and 8 weeks
respectively whereas, plants provided with 10 kg m-2 of organic fertilizer significantly (p
