ETUDE DE L’EFFET DES MODES DE FERTILISATION, DU RECHAUSSEMENT ET D’UN PAILLIS SUR LA PRODUCTION DE LA GOURGANE (Vicia faba L. VAR. major) AU SAGUENAY-LAC ST-JEAN
The interaction of fertilization methods, ridging and the use of a mulch has been established over a 4-yr period on the yield of a local cultivar of broad bean (Vicia faba L. var. major). No significant effect has been obtained on green pod production, average number of pods per hectare, average number of pods per individual plant (three interrelated parameters), contribution of green grain in percent of the whole green pod, green seed yield and dry matter production of the stubble. Yearly variations have been obtained. The differences in dry stubble production and pod number per plant indicate that broad bean yield seems to be related to the prevailing climatic conditions during plant development and particularly at the blooming stage.Key words: Vicia faba L. var. major, broad bean
