EFFECT OF FREQUENCY OF HARVEST PLANT POPULATION AND N.P.K FERTILIZER ON THE GROWTH PERFORMANCE OF VERNONIA AMYGDALINA

The trial aimed at assessing the effect of frequency harvest, plant population and N.P.K fertilizer Vernonia amygdalina(Bitter leaf) was conducted Teaching Research farm, University Abuja, Nigeria. Split plot treatment arrangement fitted into a randomized complete Block Design (RCBD) with 3 replications used. Plant used were10,000,stands/ha 40,000 stands/ha 4 weeks harvest. Data collected were Numbers branches/plants Number leaves /plants, Height/plant, leaf area index dry matter/unit.The result study showed that number branches per in plots received greater than those control plots. Leaf drastically reduced compared treated 200kg 400kg/ha not significant.Frequency harvest has significant on matter weight plants. Stands planted spacing 1m(10,000 stands/ha) developed more all growth parameters others one year after establishment.
