As pragas e os patogenos (fungos, bacterias e virus) sao responsaveis por grandes perdas da agricultura, causando injurias e doencas, alem de se alimentarem dos tecidos de plantas. As perdas na producao da agricultura mundial, devido ao ataque de pragas e doencas chegam a 37%, sendo que 13% desta perda e causada por insetos (Gatehouse et al., 1992). As plantas, possuem entretanto, um certo grau de resistencia a insetos e ha muitos anos, tem-se estudado a biossintese e a regulacao de compostos quimicos de plantas associadas com essas defesas. Atualmente, sabe-se que esses defensivos sao encontrados em varios tecidos vegetais e entre esses compostos, estao incluidos antibioticos, alcaloides, terpenos e proteinas. Entre as proteinas, estao incluidas enzimas tais como as quitinases, as lectinas e os inibidores de enzimas digestivas (Ryan, 1990). Atualmente, genes que conferem resistencia a insetos podem ser introduzidos em plantas de interesse para reduzir sua susceptibilidade. Esses genes podem ser obtidos de plantas, bacterias ou de outra origem (Schuler et al., 1998). Os inibidores de enzimas (a- amilases e e de proteinases) serao aqui descritos e estudados, relacionando-se suas funcoes como compostos de defesas de plantas contra insetos e seu potencial como ferramenta na obtencao de plantas resistentes a pragas. |

During crop cycle, growth and phenological development are influenced by different factors such as weather conditions, genetic potential, soil fertility, and system management. Management practices influences soil water retention properties and consequently crop growth an yield. In Brazil, a paradigm chance in soil management has lead conventional tillage system to give room to no-tillage cropping system, due to impacts such as erosin processes and soil organic carbon losses. No-tillage is considered a conservationist system because it includes crop rotation, mulching and only minimum soil mobilization on the seeding line. Those practices promote higher soil water storage, which are attributed o improvement of mesoporosity and non-saturated soil hydraulic conductivity. Knowledge on soil-water-atmosphere system dynamics is required on modeling crop growth and yield for supporting decision systems. Among several options, the Decision Support System for Agrotecnology Transfer (DSSAT) seem to be the most suitable for practical application since it includes more than 18 different crops models tested worldwide. After model calibration against field data, it is possible to simulate realistic scenarios for decision-makers (farmers, managers, agricultural technicians and government), as well as to identify crop constraint for scientists defining research priorities. This study aimed to evaluate CROPGRO/DSSAT model performance to simulate soybean growth, development and crop yield under no-tillage and conventional tillage systems in subtropical climate conditions, in order to support decision making in soybean cropping of Brazil.
