Opis:
Growth regulators stimulate life processes in plants, improving their stress resistance and health, which translates into higher and better quality yield. Growth regulators can improve biochemical parameters of tubers and enhance the potato’s resistance to adverse environmental conditions or pathogens. The purpose of this research was to examine the effect of biostimulators on yield and selected chemical properties of potato tubers. Four table potato cultivars were grown in a field experiment: very early Volumia and medium early Irga, Satina and Sylvana. Starting from stage 39 on the BBCH scale (crop cover complete), potato plants were treated thrice, in 10- to 14-day intervals, with the growth regulators Asahi SL, Bio-Algeen S90 and Kelpak. The reference treatment was composed of potatoes untreated with the bioregulators. The growth regulators, especially Bio-Algeen S90 (6.3 – 16.3%) and Kelpak SL (14.2-24.7%) raised the tuber yield, but the effect was statistically verifiable only in the second year, with less precipitation and lower temperature of the vegetation period. The quality of potato tubers was more strongly dependent on the cultivar-specific traits than on the applied biostimulators. In the second year, too, potato tubers contained on average 34% more N-total than in the first year. During storage, the content of N-total in tubers increased by 35-50%. After a five-month storage period, potato tubers contained more NO3 - abut less N-NH4+.

Opis:
The aim of this study has been to determine the effect of cultivation and plant protection on the content of macro- and micronutrients and yield of roots in edible carrots. The cultivation of carrot according to the principles of integrated farming resulted in a higher root mass as well as a higher total and commercial yield than in the ecological cultivation system. The plant protection had a positive effect on the root mass only in ecological cultivation. The content of crude ash in carrot roots ranged from 71.25 to 80.10 g kg-1 d.m. Roots of carrots from the integrated system contained more N-total and potassium than the ones from the ecological system. In general, carrots originating from the integrated system contained more Zn and Mn, while those grown ecologically had more Cu and Ni. After storage, the content of N-total, K, Na, Ca and Mg in carrot roots increased. Meanwhile, the P concentration tended to decrease. The plant protection methods have significant effect on the content of N-total and K and microelements. The content of nitrates (V) was modified more extensively in roots of carrots grown in the integrated system than in ecological system.
