Resumo: | Aiming to delimit areas showing climate aptitude for growing com, an agroclimatic zoning based on growing degrce-days and water deficit as agroclimatic indexes, at different sowing dates, was generated for the State of Rio Grande do Sul, Brazil. The zoning was established for sowing dates 8/1, 9/1, 10/1, 11/1,12/1, and 1/1, and six maps (1:750,000), which are presented in a reduced forre in this papei, were obtained. The zoning areas were classified as Preferential I and II. Tolerable. Marginal, and Not Recomended for com. Planalto, Serra do Nordeste, Serra do Sudeste, and Alto Vale do Uruguai are the regions showing higher potential for com in the state. Additionally, Médio and Baixo Vale do Uruguai, Missões, Depressão Central, Litoral Sul, and Campanha regions, though also showing potential for com, have the highest values of water deficit and, by using irrigation, are clssified through the temperature index. The main limitation to high com yields in the state is linked to water deficit that normaly occurs in southwestern and southeastern state arcas and in part of Depressão Central region in 9/1 to 1/1 sowing dates. Low temperaturas and frost occurrence are the most limiting factors in the sowings centered in 8/ 1. The results obtained show that climate aptitude for com in Rio grande do Sul varies according to the sowing date and region, evidencing the importante of carrying out the zoning by sowing dates. |

CORN AGRO CLIMATIC ZONING BY SOWING DATES IN THE STATE OF RIO GRANDE DO SUL, BRAZIL ZONEAMENTO AGROCLIMÁTICO DA CULTURA DE MILHO POR ÉPOCAS DE SEMEADURA, NO ESTADO DO RIO GRANDE DO SULAgroclimate aptitude. water deficit, degree-days, com, Rio Grande do Sul.Aptidão agroclimática, deficiência hídrica, graus-dia, milho, Rio Grande do Sul.Aiming to delimit areas showing climate aptitude for growing com, an agroclimatic zoning based on growing degrce-days and water deficit as agroclimatic indexes, at different sowing dates, was generated for the State of Rio Grande do Sul, Brazil. The zoning was established for sowing dates 8/1, 9/1, 10/1, 11/1,12/1, and 1/1, and six maps (1:750,000), which are presented in a reduced forre in this papei, were obtained. The zoning areas were classified as Preferential I and II. Tolerable. Marginal, and Not Recomended for com. Planalto, Serra do Nordeste, Serra do Sudeste, and Alto Vale do Uruguai are the regions showing higher potential for com in the state. Additionally, Médio and Baixo Vale do Uruguai, Missões, Depressão Central, Litoral Sul, and Campanha regions, though also showing potential for com, have the highest values of water deficit and, by using irrigation, are clssified through the temperature index. The main limitation to high com yields in the state is linked to water deficit that normaly occurs in southwestern and southeastern state arcas and in part of Depressão Central region in 9/1 to 1/1 sowing dates. Low temperaturas and frost occurrence are the most limiting factors in the sowings centered in 8/ 1. The results obtained show that climate aptitude for com in Rio grande do Sul varies according to the sowing date and region, evidencing the importante of carrying out the zoning by sowing dates. Com o objetivo de delimitar áreas com aptidão para a cultura de milho foi realizado o zoneamento agroclimático, usando soma de graus-dia e deficiência hídrica como índices agroclimáticos, em diferentes épocas de semeadura, no Estado do Rio Grande do Sul, Brasil. O zoneamento foi elaborado para as semeaduras de 1/8, 1/9, 1/ 10, 1/11. 1/12 e 1/1, obtendo-se seis mapas de zoneamento, em escala original de 1:750.000, sendo apresentados no trabalho em formato reduzido. As áreas de zoneamento foram classificadas como Preferencial I, Preferencial II, Toleradas, Marginais e Não Recomendado o Cultivo. As regiões com maior potencial para milho no estado são: Planalto, Serra do Nordeste, Serra do Sudeste e Alto Vale do Uruguai. Médio e Baixo Vale do Uruguai , Missões , Depressão Central, Litoral Sul e Campanha, embora também mostram potencial para milho, são regiões que apresentam maiores valores de deficiência hídrica e, mediante o uso de irrigação, passam a ser classificadas pelo índice térmico. A maior limitação ao alto rendimento de grãos da cultura de milho no estado, é a deficiência hídrica, que ocorre normalmente no sudoeste e sudeste do estado e em parte da Depressão Central, nas semeaduras de 1/9 a 1/1. A temperatura mínima e a ocorrência de geadas são as maiores limitações na semeadura centralizada em 1/8. Os resultados obtidos demonstram que no Rio Grande do Sul, a aptidão agroclimática para cultura de milho varia com a época de semeadura e com a região, evidenciando a importância de realizar-se o zoneamento por épocas de semeadura.
