Effect Of Varying Concentrations Of Nitrogen And Phosphorus Supply On The Growth Of Enset (ensete Ventricosum (welw.) Cheesman) Suckers

The effect of a range of factorially combined concentrations of nitrogen and phosphorusrnon the growth of enset suckers (Ellsete velltricoSlI1II (Welw.) Cheesman) was studied inrna greenhouse using Randomized Complete Block Design with seven replications. Thernexperiment was conducted on soil samples collected from Sidamo, Agereselam asrngrowing medium. To these soils, four concentrations of nitrogen (0, 10, 50 and 250rnmgl-l , designated as N" N2 , N3 and N4 , respectively); and four concentrations ofrnphosphorus (0, 9, 27 and 81 mgl-lrn, designated as PI' P2 , P3 and P4 , respectively) werernfactorially combined and added to investigate sixteen treatments. The appropriaternnutrient solutions were applied to the plants at a rate of 200 ml twice in a week Enset suckers responded to an increase in concentrations of nitrogen and phosphorusrnin solution through increases in pseudostem girth, leaf area, total biomass and tissuernnitrogen and phosphorus contents. Increasing concentrations of nitrogen and phosphorusrnin solution resulted in significant increase (P < 0.001) in pseudostem girth and total dryrnweight. The interaction between the two nutrients were also highly significantrn(P
