Resumo: | The incorporation of peanuts in the rotation systems in new productive areas requires the evaluation of the behavior of commercial varieties for the correct choice of genetic material and the sowing date, as factors that can influence the yield and quality of the peanut obtained. The objective of this work was to evaluate the effect of the sowing dates of commercial peanut varieties of different cycles. Seven varieties were evaluated: CCA and CCB (Short Cycle and high oleic); CIA, CIB and CIC (Intermediate Cycle, high oleic except for CIA); CLA and CLB (Long Cycle, high oleic). The sowings were carried out on four different dates: 1st Date (10/27/2020), 2nd Date (11/6/2020), 3rd Date (11/21/2020) and 4th Date (12/21/2020). The variables measured were: Coverage (%), SPAD Units as an indicator of chlorophyll content and photosynthetic activity, Maturity (%) and Productivity (Kg / ha). The results indicated that the varieties of CC in early dates allowed the crop to reach in the reproductive period, 60% coverage, values higher than 40 SPAD units, which determined high productivity and maturity. The CL varieties, although the photosynthetic activity did not show differences, the growth rate was low in relation to the other varieties, so they did not show differences in yield or maturity even in early plantings. The CL varieties did not show differences in productivity sown on different dates, but showed a decrease in the degree of maturity to delay the sowing moment. |

A incorporação do amendoim nos sistemas de rotação em novas áreas produtivas requer a avaliação do comportamento das variedades comerciais para a correta escolha do material genético e da época de semeadura, como fatores que podem influenciar no rendimento e na qualidade do amendoim obtido. O objetivo deste trabalho foi avaliar o efeito de datas de plantio de variedades comerciais de amendoim de diferentes ciclos. Foram avaliadas sete variedades: CCA e CCB (Ciclo Curto e alto oleico); CIA, CIB e CIC (Ciclo Intermediário, alto oleico exceto para CIA); CLA e CLB (Ciclo Longo, alto oleico). Os plantios foram realizados em quatro datas distintas: 1ª Data (27/10/2020), 2ª Data (6/11/2020), 3ª Data (21/11/2020) e 4ª Data (21/12/2020). As variáveis medidas foram: Cobertura (%), Unidades SPAD como indicador do teor de clorofila e atividade fotossintética, Maturidade (%) e Produtividade (Kg / ha). Os resultados indicaram que as variedades CC em datas precoces permitiram que a cultura atingisse 60% de cobertura no período reprodutivo, valores superiores a 40 unidades SPAD, o que determinou alta produtividade e maturidade. As variedades CL, embora a atividade fotossintética não tenha apresentado diferenças, a taxa de crescimento foi baixa em relação às demais variedades, portanto não apresentaram diferenças de produtividade ou maturidade mesmo em plantios precoces. As variedades CI não apresentou diferenças na produtividade semeada nas diferentes datas, mas apresentou diminuição no grau de maturidade para retardar a época da plantio. Â La incorporación del maní en los sistemas de rotación en la expansión de áreas productivas, requiere de la evaluación del comportamiento de variedades comerciales para la correcta elección del material genético y la fecha de siembra, como factores que pueden influenciar en el rendimiento y la calidad del maní obtenido. El objetivo de este trabajo fue evaluar el efecto de las fechas de siembra de variedades comerciales de maní de diferentes ciclos. Se evaluaron siete variedades: CCA y CCB (Ciclo Corto y alto oleico); CIA, CIB y CIC (Ciclo Intermedio, alto oleico a excepción de CIA); CLA y CLB (Ciclo Largo, alto oleico). Las siembras se realizaron en cuatro fechas diferentes: 1º Fecha (27/10/2020), 2º Fecha (6/11/2020), 3º Fecha (21/11/2020) y 4º Fecha (21/12/2020). Las variables medidas fueron: Cobertura (%), Unidades SPAD como indicador de contenido de clorofila y actividad fotosintética, Madurez (%) y Productividad (Kg/ha). Los resultados indicaron que las variedades de CC en fechas tempranas permitieron al cultivo alcanzar en el periodo reproductivo, un 60 % de cobertura, valores superiores a 40 unidades SPAD, lo que determinó alta productividad y madurez. Las variedades de CL, si bien la actividad fotosintética no presentó diferencias, la tasa de crecimiento fue baja en comparación con las otras variedades, por lo que no mostraron digferencias en rendimiento ni madurez aún en siembras tempranas. Las var. CI no evidenciaron diferencias de productividad sembradas en diferentes fechas, pero mostraron disminución en el grado de madurez a retrasar el momento de siembra.
