SIERRA-MACIAS, Mauro et al. Seed productivity and adoption of the H-520 maize hybrid in México’s tropics. agric. soc. desarro [online]. 2016, vol.13, n.1, pp.19-32. ISSN 1870-5472.

Seed is the main input for maize production (Zea mays L.), since yield potential and product quality depend on it. In the last six years, the production and distribution of the H-520 maize hybrid has been promoted, a hybrid that has high yield potential and adaptability in México’s Tropics. Thus, from 2008 to 2013, INIFAP’s Campo Cotaxtla distributed 8736 kg of certified seed, with which seed companies produced 1630 tons of certified seed, for a commercial sowing of 84 940 ha of the H-520 hybrid. In terms of profitability, there was a Benefit/Cost (B/C) relation of 1:1.52 in the production of certified seed; in grain production, the B/C relation was 1:1.09. The H-520 seed and grain production is profitable. The impact of the 84 940 hectares sown with H-520 represent an additional profit of $476.51 million and 2 548 200 workdays are generated. In the 485.20 hectares of seed production, a profit of $35.83 million is achieved, and 80 543 workdays are generated.
