<p align="justify">Rice plant (Oryza sativa l.), plants that produce the main food commodities in Indonesia namely rice. The increase in the demand for rice is increasing along with the increase in the population of Indonesia, so it takes the effort of planting rice plant (Oryza sativa l.) with planting the modified method. This research aims to determine the growth and development of rice plant by the plant height, number of leaves, the number of chicks, the number of panicle, weight of wet forage, roots, and grains, weight of dry forage, roots, and grains, 1000 grain weight, GKP, GKG as the effect of the difference of the composition and a given watering, as well as determine the productivity of rice plant (Oryza sativa l.) var. INPARI 30 on some compositions of fertilizers and irrigation. The treatment given consists of two control treatments, namely treatments with rice planting media treatment is soil and treatment II with rice planting media treatment are soil, biochar, fertilizer Compost (Enclosure), with the 2:1: 1 comparison and watering. That are located in the campus of ITB Jatinangor. Granting of inorganic fertilizers NPK given at three time of cultivation i.e., 14, 35, and 50 days after planting (HST) on each treatment. Each treatment is used 25 samples of 40 plants in plant populations. The parameters of the plant, the amount of leaves, the number of chicks, and the real number of panicles was no different with the control treatment. Treatment plant biomass parameters II has an average rating of wet weight respectively of forage, roots, and grains namely 85.072 gr, gr, and 10.34 20.28 gr, whereas the average weights of dry treatment II respectively of hijaun, root , grain was 25.9728 gr, gr, 6.416 17.16 grams the weight values higher than the control treatment had an average rating of wet weight respectively of forage, roots, and grains namely 80.056 gr, gr, 12.74 21.844 gr and the average weighted dry hijaun, roots, and grains namely 23.2672 4.89 gr, gr, 15.78 and Gr. rice plant biomass Parameter treatment II and control <br /> <br /> treatment did not differ markedly. In this experiment the plants treatment II disease infected tungro and leaf blight which causes rice crops don't grow optimally.<p align="justify">
