Resumo

Introdução: O amendoim (Arachis hypogaea L.) está entre as quatro culturas oleaginosas de maior importância comercial no mundo. O objetivo desta pesquisa foi avaliar a resposta agronômica desta cultura em diferentes densidades de plantio. Materiais e métodos: O experimento foi conduzido na Fazenda “Elpidio Sosa”, município de Sagua La Grande, província de Villa Clara, Cuba. Foi utilizado o delineamento em blocos casualizados com uma cultivar de amendoim (Cascajal rosado) e quatro densidades de plantio (13,3; 11,1; 9,5; 8,3 plantas m−2) em três repetições. Resultados: Os resultados mostraram que a menor densidade de plantio aumentou os valores dos componentes de rendimento: número de frutos e sementes por planta, peso de frutos e sementes por planta e rendimento biológico, enquanto na maior densidade de plantio o rendimento de frutos, sementes e índice de colheita aumentaram significativamente. Discussão: Essas descobertas demonstram que otimizar a densidade de plantio é uma prática agrícola importante para explorar todo o potencial de rendimento e alcançar um aumento contínuo na produção de amendoim sem aumentar o uso de insumos. Conclusões: É evidente a influência positiva da maior densidade de plantio (13,3 plantas m-2) na produtividade de frutos e sementes, no peso de 100 frutos e 100 sementes, no rendimento biológico e no índice de colheita.
