ABSTRACT
In 2000 – 2002 a strict field experiment was carried out to investigate the effect of foliar fertilization and/or chemical plant protection on seed yield of two white lupin cultivars, ‘Bardo’ traditional and ‘Katon’ self-completing. The plants were sprayed once at the end of flowering and twice at the beginning and at the end of flowering. 5, 10, 15 and 20% urea solutions were supplemented with a 5% Mikrokompleks and 0.7 dm3·ha-1 of Sarfun (carbendazim), Mikrokompleks + Sarfun or they were used separately each. ‘Bardo’ yielded about 24% higher than ‘Katon’. ‘Bardo’ yielding was most enhanced by Sarfun chemical plant protection, while ‘Katon’ yielding – by all the urea treatments applied with Mikrokompleks + Sarfun. There was observed no significant effect of the foliar fertilization and/or plant protection treatments date and number on the seed yield and most of seed yield components and seed viability and vigor. A double plant spraying at the beginning and at the end of flowering increased significantly 1000 seed weight, only. Positive results of Sarfun application in white lupin seed production suggest that chemical plant protection is of great importance for the potential of this species, while the impact of foliar fertilization with urea + microelements will depend on the availability of macro- and microelements in soil and the effectiveness of symbiosis.
Key words: foliar treatments, urea, Mikrokompleks, Sarfun, white lupin.
