The objectives of the study is to find out the influence of spraying concentration and interval of hyponex leaves fertilizer toward tree seeds growth. The advantages of the study are to enhance the insights and information toward forestry plants, especially trees. Besides, it is tried to give alternatives toward related institutions to develop tree plantation by the se of leaves fertilizer treatment, especially hyponex to produce high quality product. The hypotheses of the study are 1) there is an interaction between hyponex leaves fertilizer concentration and spraying interval toward the growth of tree seeds, 2) the use of different concentration of hyponex 1 gr/lt leaves fertilizer to increase the growth of tree plantation, 3) the use of different spraying interval once in 5 days leaves might influence the growth of tree plantation. This is a group randomized design study by using 2 factors. First is the concentration of hyponex leaves fertilizer, consists of P1 = the concentration of hyponex leaves fertilizer 0,5 gr/lt, P2 = the concentration of hyponex leaves fertilizer 0,75 gr/lt, P3 = the concentration of hyponex leaves fertilizer 1,00 gr/lt, P4 = the concentration of hyponex leaves fertilizer 1,25 gr/lt. Whereas the second factor is spraying interval, consist of M1 = the spraying intervali once in 5 days, M2 = the spraying intervali once in 10 days, M3 = the spraying intervali once in 15 days. In order to analyze the research data from earch of observation parameter analyzed the use of varied search related to factorial group randomized design, the analysis result tested using F test with the percentage about 5 %. To compare one treatment to another by the use of Duncan test by the percentage for about 5 %. Based on research result indicate that in the observation parameter of the seed height growth there are interactions between hyponex leaves fertilizer concentration and spraying interval during period of observation of 14 hst by the highest treatment combination is P3M1. Besides, the diameter increasing parameter of the stem indicate interactions during the observation periods of 21 hst, 35 hst, 42 hst dan 49 hst with the highest treatment combinations is P3M1.
