Located on the land of Fasum Villa Padma 1, USA Rumbai, research will be carried out which aims to examine the effect of Atonik ZPT doses on the growth of green betel plant stem cuttings. It is suspected that the dose of Atonik ZPT affects the growth of green betel plant seeds. This research was conducted using a completely randomized design of 4 treatments with 5 replications. The observation data is processed by analysis of variance using the SPSS version 17 program, if Ho is rejected, it continues with the DMRT test at 5% level. The four treatments in the study of the efficacy of Atonik ZPT doses on the growth of stem cuttings of green betel plants (Piper betle. L) were the 4 doses of Atonik ZPT treatment; 2, 4, 6 and 8 ml/l water. The research was carried out using polybags filled with planting media mixed with topsoil and compost in a ratio of 3:1. The observation parameters observed were: Percentage of life, Number of shoots (fruit), Shoot height (cm), Number of leaves (strands), Widest leaf length (cm), and Widest leaf width (cm). The research results did not show a real effect. The best treatment is a ZPT dose of 2 ml/l water.

Liquid organic fertilizer is a natural fertilizer that can improve the physical, chemical and biological conditions of the soil. Contains nutrients that can increase plant growth. The aim of this research was to determine the effect of fertilization on the vegetative growth of Taiwan White Guava (Psidium guajava L. cv. Taiwan White) and to study the length, width and height of the leaves. This research was conducted at the Deni’s Farm guava plantation located on Jl. Bypass, Minas District, Siak Regency. This research was carried out using data collection techniques in the form of observation, direct observation and documentation as methods. In this research, a qualitative descriptive approach was used in data processing. Based on the research results, it can be concluded that liquid organic fertilizer or NPK fertilizer has an effect on Psidium Guajava L. cv. Taiwanese white. If the fertilizer concentration or dosage is not too high and according to the dosage, Psidium guajava L. cv White Taiwan will produce good quality growth. At a concentration of 3 ml/l (P3) the tallest plants were obtained, at a concentration of 1 ml/l (P1) and 4 ml/l (P4) the leaves were very numerous, leaf length, leaf width and. stem height is obtained. good quality. While the average leaf length of the 10 samples was 11.1 cm, Psidium guajava L. cv. The average width of Taiwanese white leaves is 5.7 cm, and the highest tree height with 6 data collection marks is the fourth mark, namely. height 140 cm.
