Abstract

Research entitled "The Effect of Moringa Leaf POC NPK and NPK 9:25:25 on the Growth and Production of Green Okra Plants (Abelmoschus esculentus L.)" was conducted at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Jl. Air Dingin Ujung, Air Dingin Village, Bukit Raya District, Pekanbaru City for 3 months from October 2024 to December 2024. The study aims to determine the interaction and main effects of Moringa Leaf POC and NPK 9:25:25 on the growth and production of green okra plants. This study used a factorial Completely Randomized Design (CRD) consisting of 2 factors. The first factor is the concentration of Moringa Leaf POC consisting of 4 treatment levels, namely 0, 100, 200 and 300 ml/L of water. The second factor is the dose of NPK 9:25:25 consisting of 4 treatment levels, namely 0,3,6 and 9 g/plant. The parameters observed were plant height, flowering age, number of stomata, percentage of stomata opening, harvest age, number of fruits per plant, fruit weight per plant, fruit weight per fruit, and number of remaining fruits. Observation data were analyzed statistically and carried out with a further test of Honestly Significant Difference (HSD) at the 5% level. The results showed that the effect of the interaction of Moringa Leaf POC and NPK 9:25:25 was significant on the parameters of plant height, flowering age, number of stomata, percentage of stomata opening, harvest age, number of fruits per plant, fruit weight per plant, fruit weight per fruit, and number of remaining fruits. The best treatment was a combination of Moringa Leaf POC concentration of 300 ml/L water and NPK dose of 9:25:25 9 g/plant. The main effect of Moringa Leaf POC was significant on all observation parameters with the best treatment concentration of 300 ml/L water. The main effect of NPK dose of 9:25:25 was significant on all observation parameters with the best treatment dose of 9 g/plant.
