Zusammenfassung: | In order to quantify the effects of different levels of water, organic fertilization (effluent of
biodigestor) and mineral fertilizer on the development of culture of onion (Allium cepa L.), was held on this research
in the Departamento de Engenharia Rural da FCAV/UNESP- SP / Brazil. To achieve the proposed objectives,
referred to the cultivation of onion at different levels of water, is also making use of organic manure (in the dose of
60 m3 ha¡¥1) and mineral (conventional), for purposes of comparison. From the data obtained, raised up figures for the
plant height, average diameter of bulbs, and plant production per hectare and matric potential of water in the soil.
The analysis of results, it was concluded that the mineral fertilization of onion can be replaced by organic
fertilization (bovine), effluent of biodigestor. The levels of water corresponding to 100 and 150% of the maximum
considered evapotranspiration, are ideal for the development of culture, organic fertilizer and kept the soil with the
highest potential matrix that the application of mineral fertilizer for all levels of water applied.
Com a finalidade de se quantificar os efeitos de diferentes niveis de agua, adubacao organica (efluente
de biodigestor) e adubacao mineral sobre o desenvolvimento da cultura de cebola (Allium cepa L.), realizou-se a
presente pesquisa no Departamento de Engenharia Rural da FCAV/UNESP- SP/Brasil. Para alcancar os objetivos
propostos, submeteu-se a cultura de cebola a diferentes niveis de agua, fazendo-se tambem uso da adubacao organica
(na dose de 60 m3 ha £¼1) e mineral (convencional), para efeito de comparacao. A partir dos dados obtidos,
levantaram-se valores referentes a altura das plantas, diametro medio de bulbos, producao por planta e por hectare e
potencial matricial da agua no solo. Da analise dos resultados, concluiu-se que a adubacao mineral da cebola pode
ser substituida pela adubacao organica (origem bovina), efluente de biodigestor. Os niveis de agua correspondentes a
100 e 150% da evapotranspiracao maxima considerada, sao os ideais para o desenvolvimento da cultura, e a
adubacao organica manteve o solo com potencial matricial mais alto que a aplicacao de adubo mineral para todos os
niveis de agua aplicados. |
