Relationship between nitrogen form and the development and yield of Lupinus albus L. from different countries
This paper discusses the influence of form of nitrogen (N) used as fertilizer, such as N2, NH4+, NO 3?, [NH4+ + NO3 ?] and -NH2, on the development and yield and the protein content and yield of low-alkaloid cultivars of Lupinus albus L. from Poland, Spain, and Chile. The experiments were carried out in a greenhouse and plants were grown in perlite. The different forms of N used significantly influenced lupin development and yield. Plants only developed normally in treatments where N was delivered in the molecular form N2 or as [NH4 + + NO3?]. For the other forms of N anomalies like necrosis, chlorosis, and small leaves were present. In contrast to cv. Butan, the N used as NH4+ disturbed flowering in cvs. Multolupa and Marta, which produced no seed. Moreover, N form also influenced protein seed protein content and yield.
