Abstract

The aim of the study was to determine the interaction and main effect of Palm Oil Palm Abu Janjang and POC NASA on the growth and production of sweet potato plants. The research was carried out at UPT UIRA Farm Agro FP UIR Experimental Garden, Jalan Teropong No. 62, Kubang Jaya Village, Kec. Siak Hulu, from April to July 2021. The study used a two-factorial Completely Randomized Design, where the first factor was the dose of Abu Janjang Kelapa Sawit (A) which consisted of 4 levels, namely 0, 50, 100, and 150 g of mounds and the second factor namely the concentration of NASA POC (P) which consisted of 4 levels, namely 0, 3, 6, and 9 cc, so that 16 treatment combinations consisting of 3 replicates were obtained so that the total was 48 experimental units. Parameters observed were harvest age, tuber weight, tuber diameter, tuber weight planted, and tuber weight. Obtained observational data were tested statistically and tested further BNJ 5%. The results showed that the interaction effect of Palm Oil Palm Abu Janjang and POC NASA significantly affected the observation of flowering age, harvesting age, number of fruits per plant, fruit weight per plant, and fruit weight per plot. The best treatment was a combination of Palm Ashes at a dose of 150 g/mound and POC NASA with a concentration of 6 cc (A3P2). The main effect of Abu Janjang Kelapa Sawit is significant for all observation parameters. The best treatment is Abu Janjang Kelapa Sawit dose of 150 g/bundle (A3). The main effect of NASA's POC is real on all observation parameters. The best treatment was POC NASA with a concentration of 6 cc/bundle (N2).
