Abstract

The study investigated a Polish white lupin ‘Butan’, and its yielding depending on the interrow width and plant density.
The mean many-year lupin seed yield was 3.05 t ha-1 and it strongly depended on the total rainfall and total
temperature over the generative plant development. The mean discrepancy in the seed yield across the research years, due to a considerable variation in the total rainfall, ranged from 1.59 t ha-1 to 7.43 t ha-1. There was no
significant effect of the factors applied on white lupin yielding. Only the number of pods per plant depended on the factors and it was significantly higher when lupin was grown in narrow rows, with the lowest plant density. Also, HI and SPAD values were significantly higher for 16 cm row width. The LAI value did not depend significantly on either of the two factors. Content and yield of protein depended proportionally on the sum and distribution of precipitation in the following years.
