Abstract Suboptimal land is a problematic land for rice crop growth. This is because the nutrient content in the soil is very low but the content of iron or aluminium elements is so high, that causes toxicity to plants, and then inhibited plant growth. Therefore, it is necessary to add organic fertilizer to the soil, one of which is cow manure that is available at all times and easy to obtain. In addition to cow manure, kieserite is also important to be given into the soil because kieserite contains magnesium nutrients that are badly needed for plant growth. This research purposes to see the best response of rice plants of Batang Piaman variety to fertilizer given to increase growth and yield on suboptimal land. This study used Completely Randomized Design with 3 fertilizer treatments [100% inorganic fertilizer, cow manure 5 tons/ha+150kg/ha kieserite, and 10 tons/ha of cow manure without kieserite]. Each treatment is replicated 5 times. The data is analyzed with a variety of variance and if the results differ noticeably followed by Honestly Significant Difference [HSD] Post Hoc Test in level 5%. Observations had made on some quantitative parameters. From the results of the study obtained that the best response from rice plants of Batang Piaman variety is obtained in the treatment of cow manure 5ton/ha+150kg/ha kieserite that provides high growth of plants 90 cm and the total number tillers of rice as 34 stems and a yield of 6.52 tons/ha on suboptimal rice field.
