2.6.1. Ipomoea aquatic (kangkung)
A randomized block was designed having two fertilizer treatments: (A) blank and (B) a compost soil with SBE-based bio organic fertilizer. All treatments were replicated three times. Parameters observed were average number of leaves and average height of kangkung. The fresh weight of total biomass, shoot and root were measured and used in a statistical analysis.
2.6.2. Abelmoschus esculentus (okra)
Two sets of planting block were set up; each set contained 3 planting pots having different fertilizer treatment: (A) blank and (B) a compost soil with SBE-based bio organic fertilizer. All treatments were replicated three times. Seeds were soaked in water for 24 h to allow water to nourish the seed for better germination before planted. The physical parameters observed were plant height, root length, number of leaf, size of leaf and number of fruit. Two performance and efficacy assessments at different cultivation period were conducted i.e. in a month of cultivation and after a complete 3-month trial. The plants were harvested after the set cultivation periods. The physical parameters of the plant (fresh weight and or dry weight of the total biomass, shoot and root) were measured and used in a statistical analysis.
