Abstract

Compost and biochar are organic materials that can improve the function of soil as a growing medium in cultivation. Inpago 8 is a kind of upland rice which is grown in the dry land. This study was conducted to determine the effects of compost and biochar on dryland to the growth and yield of Inpago 8 rice plant. The experiment was conducted on dry land in Natar Experimental Station, South Lampung from January 2015 until May 2015. Six treatments were tested in this study consisted above: (A) control (without compost and biochar), (B) biochar rice husk 5 ton/ha (t/ha), (C) biochar rice husk 10 t/ha, (D) compost 5 t/ha, (E) biochar rice husk 5 t/ha + Compost 5t/ha, and (F) Biochar rice husk 10 t/ha + compost 5t/ha, using a randomized block design with four replications. Observations were conducted on the components of growth and yield of Inpago 8 rice plant, data analysis used Duncan's test. The result showed that the best appearance of the growth and yield of Inpago 8 rice plant is the application of biochar rice husk 5 t/ha + compost 5t/ha.
