Pengaruh ZPT Dekamon Dan Pupuk NPK 16:16:16 Terhadap Pertumbuhan Okulasi Tanaman Jeruk Kasturi (Citrofortunella Microcarpa)

Siti Khadijah (164110275), research entitled The Effect of ZPT Dekamon and NPK 16:16:16 on Grafting Growth of Kasturi Orange (Citrofortunella microcarpa) under the guidance of Mr. Ir. Suhaswardi, MP. This research was carried out in the experimental garden of the Faculty of Agriculture, Riau Islamic University, Pekanbaru from November 2020 to January 2021. The purpose of this study was to determine the interaction and main effect of ZPT Dekamon and NPK 16:16:16 on the growth of grafting of musk citrus plants. This study used a 2 factorial completely randomized design. The first factor was ZPT Dekamon (D) which consisted of 4 levels, namely 0, 1, 2 and 3 cc/l. The second factor was the dose of NPK 16:16:16 (N) which consisted of 4 levels, namely 0, 1.5, 3, and 4.5 g/plant. Parameters observed were age of grafting shoots, percentage of grafting life, shoot height, shoot diameter and number of leaves on shoots. Observational data were statistically analyzed and continued with the BNJ test at the 5% level. The results showed that the interaction of ZPT Dekamon and NPK 16:16:16 significantly affected the age of buds growing, percentage of grafting life, and number of leaves on shoots. The best treatment combination was a combination of ZPT Dekamon 3 cc/l and a dose of NPK 16:16:16 4.50 g/plant (D3N3). The main effect of Dekamon ZPT was significant on the age of grafting shoots, percentage of grafting life, plant height and number of leaves on shoots. The best treatment was ZPT Dekamon 3 cc/l (D3). The main effect of NPK 16:16:16 was significant for all parameters. The best treatment was NPK 16:16 4.5 g/plant (N3)
