Abstract

The research that has been conducted with the aim of determining the Growth Response and Production of Purple Eggplant (Solanum melongena L.) to the Provision of Azolla POC and TSP. This research was conducted at the Experimental Garden of the Faculty of Agriculture, Riau Islamic University for 5 months starting from March 2023 to July 2023. This study used a Factorial Completely Randomized Design consisting of two factors. The first factor is Azolla Liquid Organic fertilizer, consisting of 4 levels, namely 0, 600, 1,200, 1,800 ml per polybag. The second factor is TSP fertilizer consisting of 4 levels, namely 0, 2.5, 5, 7.5 g per plant. So that 16 treatment combinations with 3 replications were obtained, so there were 48 experimental units. Each experimental unit/plot consists of 4 plants and 2 plants as observation samples, so that the total number is 192 polybags/plants. The parameters observed were plant height, flowering age, harvest age, number of fruits per plant, fruit weight per fruit, fruit weight per plant and number of remaining fruits per plant. Observation data were analyzed statistically and continued with the BNJ test at the 5% level. Based on the study, it can be concluded that the best treatment is azolla liquid organic fertilizer 1,800 ml/polybag and TSP 7.5 g/plant. The effect of the interaction of azolla liquid organic fertilizer and TSP had a significant effect on the parameters of plant height, flowering age, harvest age, number of fruits per plant, fruit weight per plant, and number of remaining fruits. The best treatment was a combination of azolla liquid organic fertilizer doses of 1,800 ml/polybag and TSP 7.5 g/polybag. The main effect of azolla liquid organic fertilizer was significant on all observation parameters with the best dose of azolla liquid organic fertilizer 1,800 ml/polybag. Thus, the treatment of azolla liquid organic fertilizer and TSP had a significant effect on purple eggplant plants. Keywords: Azolla Liquid Organic Fertilizer, Purple Eggplant, TSP
