Farmers on suboptimal land are generally economically disadvantaged and need to be supported by low-cost technology. The study aimed to find out a low input technology package in maize cultivation on suboptimal land in Riau Province. The research was carried out on the tidal agroecosystem overflow type C, around the Mandau River on alluvial land, peat, and alluvial + peat mixture in Siak District. Time of study in March to December 2018. The materials used were hybrid maize varieties such as Nasa 29, Bima Uri 19, and composite maize Bisma and Sukmaraga, Urea, TSP, KCl, farm yard manure, dolomite, locality liquid organic fertilizer (LLOF), grilled ash, biological fertilizers, decomposers, pesticides, herbicides. There are 4 fertilization packages, i.e.: A (high dosage), B (high dosage + LLOF + Grilled ash), C (50% dosage + LLOF + grilled ash), D (low dosage). Experiments were designed using randomized complete block design and repeated three times. To find out whether farming is profitable or not economically, it is analyzed by using Benefit Cost Ratio. The results showed that Nasa 29 and Sukmaraga varieties produced the best average growth and yield for all soil types and fertilizer doses of 4.0 t ha-1 and 3.9 t ha-1 dry seeds, respectively. NASA 29 can produce 6.2 t ha-1 dry seeds in a mixture of peat + alluvial soil even though the dose of chemical fertilizer is reduced by 50%. Reducing the dose of chemical fertilizer can be done to improve the ability of farmers to buy fertilizer depending on the type of soil and the availability of LLOF and grilled ash. Mixture of peat and alluvial is good soil for maize growth if combined with fertilizer package B. Decrease in chemical fertilizer 50% (package C) causes yields to fall to 6.23 t ha-1 and farmers get a profit of Rp 12,418,000 per planting season with B/C 1.9.
