EFEITO DE ÉPOCAS DE DEFICIÊNCIA HÍDRICA NA EFICIÊNCIA DO USO DO NITROGÊNIO DA CULTURA DO FEIJÃO cv. IMBABELLO

Abstract: Visando identificar estádios da cultura de feijão que apresentam a menor sensibilidade ao estresse de água no solo, nos quais a irrigação pode ser omitida sem um significativo decréscimo na eficiência de uso de nitrogênio e na produtividade final, foi realizado experimento em um solo franco arenoso (Typic Haplustoll) na Estação Experimental da Universidade Central do Equador, "La Tola", em Tumbaco-Pichincha, Equador, entre julho e novembro de 1994. Os tratamentos consistiram da combinação de sete regimes de ir… Show more

“…Another factor that can directly affect the symbiosis is the occurrence of water deficiencies, with negative effect, especially during flowering and pod filling (Calvache & Reichardt, 1996), besides affecting the survival of rhizobia in the soil. How the test was conducted under rainfed and without application of fertilizer, under conditions of small producers, the differences between the DBS and REEF strains BR 3267 and INPA 3-11B compared to other strains studied, show the high ability of these strains in the production of plant biomass.…”
