ABSTRACT:

The experiment was conducted at the Teaching and Research Farm University of Jos, Jos during the raining season of 2019\2020 to determine the effect of plant spacing on the growth and yield of Rosell Hibiscus sabdariffa L. It is laid out in [RCBD] with four [4] treatments replicated three [3] times. The treatment are 15cm by 75cm, 20cm by 75cm, 25cm by 75cm and 30cm by 75cm and the parameters of the studies are viz; PH, NB, LL, LW, data collected were subjected to ANOVA using a Statistical Analysis [SAS] and means were separated using Least Significant Difference [LSD]. Base on there sult obtained from this study, it shows that for optimum yield of hibiscus sabdariffa L, wider spacing of 30cm by 75cm shows superiority over other treatment, hence wider spacing is recommended for Hibiscus Sabdariffa L because at a wider spacing, plants do not compute for growth resources, and the plants has the oppoturnity to produce more numbers of productive branches and the more the productive number of branches, the more the yield.
