Abstract

Indonesia’s palm oil production needs to be developed, generative sapodilla cultivation has a very long growth. The effort that can be done to increase the growth of sapodilla seeds for the provision of quality seedlings. Giving chitosan expected to increase the growth of sapodilla seeds because there are chitosan content that accelerate plant growth, and age planting shorter. The aim of this research is to know the concentration and time of spraying of chitosan to be applied to generative sapodilla seeds. The study used Randomized Complete Block Design (RAKL) of 2 factors. The first factor was phytosanic concentration consisting of four levels (0, 2, 4, and 6 mL/L) and the spraying time consisted of three levels (morning, afternoon, and morning and afternoon), each treatment combination was repeated three times. that the concentration of chitosan have significant effect to the leaf area with the best treatment at 6 mL/L concentration and the time of spraying treatment had significant effect on the increase of the number of branches with the best treatment during the morning spraying.
