Com o objetivo de comparar os danos causados pelo percevejo Nezara viridula (L.) na cultivar de soja (Glycine max Merrill), 'Bragg', de semente pequena, foram conduzidos dois experimentos em casa-de-vegetacao e um experimento em campo, no Centro Nacional de Pesquisa de Soja, da EMBRAPA, em Londrina, PR. Alem do dano, observou-se a localizacao das sementes danificadas em diferentes alturas da planta, e a capacidade de dano do percevejo. Os resultados indicaram menor peso e percentagem de sementes danificadas nas linhagens BR 79-15807 e BR 79-15197, do que na 'Bragg'. Observou-se que os percevejos se alimentaram principalmente nos tercos superior e medio da planta. O numero de sementes picadas/percevejo/dia foi de 3,7 na 'Bragg'e de 3,4 na BR 79-15807. Em outro experimento conduzido em campo, visando testar a interacao dano de percevejo Piezodorus guildinii (West.) e fungo Nematospora coryli Peglion, observou-se que as plantas introduzidas (PI's) 227.687 e 86.490 apresentaram maior tolerancia a acao do percevejos do que a 'Bragg'. A percentagem de sementes sadias foi superior nas PI's em relacao a 'Bragg', quando submetidas ao ataque de percevejos P. guildinii infectado ou nao com N. coryli. |

The application of nitrogen soil fertilization is one of the factors that leads to high yields in common bean crops. Therefore, the aim of this work is to evaluate in silico the effects of nitrogen rates and topdressing dates on common bean yield in three different sowing dates and three growing seasons in Goias State, Brazil. The CSM-CROPGRO-DRYBEAN crop model was parameterized, validated, and applied to simulate common bean yields in wet (Nov to Dec), dry (Jan to Feb), and winter (May to Jun) seasons for nitrogen rates applied at sowing and as topdressing. An economic analysis was carried out to assess the viability of each scenario. Nitrogen rate was the most important factor in the wet season in obtaining high yields. Yields increased as nitrogen rates increased. In the dry season, sowing date was the most important factor in obtaining the highest yields. However, this season presented the lowest increase in yield per kg of nitrogen, whereas the winter season presented the highest increase. In the winter season, nitrogen rate was also the most important factor in obtaining high yields, and sowing date and topdressing had a low effect on yield. The highest crop economic return was obtained with N rates (sowing/topdressing) of 60/180 kg ha -1 and 40/120 kg ha -1 for the wet and winter seasons, respectively. The bean price was fixed at US$ 0.85 kg1. Therefore, the best management strategy is an early sowing date for the dry season, high nitrogen rates and an early sowing date for the wet season, and high nitrogen rates for the winter season.
