Resumo

Lupinus albescens é uma espécie freqüente nos locais de arenização no Rio Grande do Sul (RS), com alta rusticidade e rápida cobertura vegetal, mostrando potencialidades para recomposição de áreas degradadas. O objetivo foi avaliar a emergência e o desenvolvimento de L. albescens, com e sem aplicação de adubação mineral consorciada com Butia lallemantii. As sementes foram coletadas em três populações e submetidas à escarificação por 40 segundos. A semeadura foi feita entre nove fileiras (2 x 1 m) de B. lallemantii aplicando-se 0 e 30 g/cova do fertilizante mineral NPK (5-20-20). As avaliações foram: número de plantas por cova (NPC), altura (cm) e diâmetro do caule (mm), nos períodos de 30 e 60 dias, assim como a porcentagem de emergência de plantas/m2 (PEP) e o total emergência de plantas (TEP) ao longo de 240 dias, utilizando delineamento em blocos casualizados. Os resultados mostraram considerável PEP e altura aos 30 dias para as plantas do bloco 2. A dose de 0g/cova do fertilizante NPK proporcionou maior NPH. Portanto, a semeadura de L. albescens consorciada com B. lallemantii apresentou maior PEP, NPC sem o uso de adubação (30 dias) e maior altura das plantas entre as plântulas de diâmetro do estipe médio.
