Production results of intensification of cultivation technologies in three lupin (Lupinus l.) species

Abstract

The paper presents results of 3-year field studies carried out in a split-block design in four replications in the years 2012–2014 at the Agricultural Experiment Station in Mochełek (Poland). The effect of intensification of cultivation technologies on the yield of morphologically diversified cultivars of white (Lupinus albus), yellow (L. luteus) and narrow-leafed lupin (L. angustifolius) was examined. Traditional cultivars of white and yellow lupin gave signifi­cantly higher yields than the self-completing ones, as opposed to narrow-leafed lupin in which the self-completing cultivar had higher yields. Increasing expenses on industrial production means caused an increase in the yield of all the studied species. Seed yield of white and narrow-leafed lupin was significantly the highest in high-input technol­ogy, while that of yellow lupin in high- and medium-input technology. In all lupin species, insignificant diversifica­tion was observed in the number of pods per plant in medium- and high-input technologies as well as in low- and medium-input technologies. A significant increase in the seed yield along with an increasing intensity of the culti­vation of traditional and self-completing cultivars of white and yellow lupin, as well as self-completing cultivars of narrow-leafed lupin, resulted mainly from developing a higher number of pods.
