Track 4-1-3: Breeding Range Grasses and Legumes for Biomass and Stress Tolerance
Description
Tanzania guinea grass is a forage plant recognized in Brazil and part of Latin America due to high forage production in intensive production systems (Jank et al., 2010). In irrigation conditions, this plant has also shown excellent performance in semiarid areas. In general, this grass develops well in regions with above 700 mm rainfall, medium texture soils and good fertility, and the main limitation for its production in the tropics is the rainfall (Jank et al., 2010).
Future scenarios point to temperature increases, directly impacting evapotranspiration, and there are also many uncertainties in relation to precipitation, with studies indicating increasing droughts in semiarid regions and droughts in areas where this is not currently common. Using tools that can predict this grass productivity in drought situation is very useful in the decision-making process and in the search for pasture use more sustainable strategies.
Simulation models use based on biomass production data is a tool that has helped technicians, producers and governments in fast decision-making processes. This study type has evolved along with geographic information systems, enabling geo processing techniques application, allowing crops productive potential areas delimitation in a quick manner and with reliable results. Suitable areas predetermination allows cost, time and risk reduction with Tanzania guinea grass pastures formation. This research was conducted in order to carry out a simulation to determine suitable areas for Tanzania guinea grass cultivation under rainfed conditions, using forage production data in a Brazilian semiarid environment.
