Abstract :
This research has been carried out in the Experimental Garden of the Faculty of Agriculture, Riau Islamic University, Jalan Kaharuddin Nasution Km 11, Air Dingin Village, Bukit Raya District, Pekanbaru City. This research lasted for 4 months from April to July 2019. The purpose of this study was to determine the effect of the interaction and main POC Nasa and TSP fertilizer on the growth and production of purple eggplant. This research uses factorial completely randomized design (CRD). The first factor is POC Nasa (N) consisting of 4 levels (N0, N1, N2, N3) and the second factor is TSP fertilizer (P) consisting of 4 levels (P0, P1, P2, P3). So that obtained 16 treatment combinations with 3 replications. The parameters observed were plant height, flowering age, age of harvest, number of fruits per plant, long fruit length, weight of fruit per fruit, weight of fruit per plant, and number of remaining fruit. The results of this study indicate that the influence of the interaction of POC Nasa and TSP fertilizer has a significant effect on the length of the longest fruit, fruit weight per fruit, and weight of fruit per plant. The best treatment resulted in the treatment of POC Nasa 6 cc / L water and fertilizer TSP 10 g / plant. The main influence of POC Nasa gives a significant effect on plant height, harvest age, number of fruits per plant, longest fruit length, fruit weight per fruit, weight of fruit per plant, and number of remaining fruit. The best treatment of POC Nasa 6 cc / L water. The main effect of TSP fertilizer has a significant influence on plant height, flowering age, age of harvest, number of fruits per plant, longest fruit length, fruit weight per fruit, and the number of remaining fruit. The best treatment of 15 g TSP fertilizer / plant.
