Abstract

The research was carried out during 2010-2012 on the preluvosoil from Agricultural Research and Development Station Oradea. Two factors were studied: organic fertilization and annual fertilization. Organic fertilization included the variants: control, Lupinus angustifolius; vetch oat ryegrass; Lupinus angustifolius oat; Lupinus angustifolius oat rape; rape; rape oat; manure 25 t/hectare and manure 50 t/hectare. Annual fertilization included the graduations: N0P0, N120P90. Green manure were seeded in the 15th July, 3rd and 20th August like second crop. The biggest green manure yields were obtained seeding in 15th July. Both in the first year of the green manure effect, the biggest yields maize were obtained in the mixture of the Lupinus sp.: 5510 kg/ha and 3990 kg/ha in Lupinus sp. oat rape without chemical fertilizers, 6868 kg/ha and 5110 kg/ha in the variant with N120P90; in the variant with Lupinus sp. oat the yields were very close. The yield maize obtained in the Lupinus sp. mixtures were bigger than the yield maize obtained using the mixture vetch oat ryegrass recomanded by biological school. In the all mixture of green manure the yields maize obtained were bigger than the yields obtained in the variant with Lupinus sp. pure crop. The manure determined to obtain the yields maize bigger than the yields obtained using the mixture of green manure.

Keywords: green manure, organic fertilization, yield, water use efficiency, maize
