ResumoResearch concerned three genotypes of white lupin (Lupinus albus L.) from three countries: the Romanian white lupin cultivar Medi, the Serbian source De Voivodina, and the Turkish source De Turcia. The type of soil on which was carried the research was a brown podzolite, with a low acid reaction (pH 5.90 in Ap, poorly supplied with humus, phosphorus, and potassium, with a base saturation degree of V% = 78% and with medium fine texture in the first 49 cm. The Medi white lupin cultivar was noted among the white lupin cultivars, whose average yield over the three periods of sowing was 2640 kg/ha. The De Voivodina source had a close yield, the difference compared to the Medi white lupin cultivar lacking significance. The lowest yield was in the De Turcia source, i.e. only 1840 kg/ha. Among sowing periods, we noticed, with practically equal yields, the variants sowed between March 20 and 25 and between April 10 and 15. Crops in the field amplitude within the range investigated was 1950 kg / ha in variant sown at the end of May last decade, the origin is Turkey and 2840 kg / ha in planted variant of March last decade the variety Medi. This magnitude of about 1000 kg / ha in variants with extreme values highlights the practical importance of links taken year study that the optimum genotype cultivated and sown in habitat conditions that have made inquiries.
