The following factors were examined: I – three varieties of edible potato: Honorata, Jelly, Tajfun, and II – four types of biostimulators used in three periods (beginning of flowering, full flowering and after flowering of the plants): Kelpak SL®, dosage 0.20 mg l–1, Titanit®, dosage 0.20 mg l–1, GreenOk®, dosage 0.20 mg l–1, BrunatneBio Złoto®, dosage 0.20 mg l–1 and a control variant (without the use of biostimulators). The aim of the study was to determine the effect of biostimulators on the dry matter yield and starch yield of edible potato tubers. The content of dry matter was determined by means of a dry weight method. The starch content was determined using the Reimann hydrostatic balance. Dry matter yield and starch yield were calculated as a product of the total yield and the content of individual components. The results obtained were statistically analysed with the use of the analysis of variance. The use of biostimulators in the experiment increased the amount of dry matter yield and the yield of edible potato tuber starch as compared with the control plot. The reaction of the different varieties to the biostimulators used was diverse. The highest dry matter yield and starch yield was produced by the Jelly variety. The BrunatneBio Złoto biostimulator significantly increased the dry matter yield and starch yield as compared with the control variant. The Jelly variety produced the highest dry matter yield and starch yield, while the Honorata variety reacted with a decrease in the yield in relation to the variant in which the biostimulator was not used. The diverse climatic conditions prevailing during the growing season in the years when the research was conducted influenced the yield of dry matter and starch.

Germination of three soybean cultivars: Abelina, SG Anser and Merlin was examined in a laboratory study as affected by products containing effective microorganisms: EM5, EM Farma and EM Mulit Grower. Germination in an aqueous environment was the control treatment. Analysis of germination capacity after 5 and 10 days from the beginning of the experiment (as indicated by International Seed Testing Association) was based on two-way analysis of variance. A logistic function was used to analyse the average number of germinating seeds over time (for each cultivar × product). Based on this function, the rate of germination and the time (day) when the greatest number of seeds germinated were determined. Regardless of the applied product, cv. Abelina had the best germination performance at the first and second date of counting as its germination capacity was 55 and 86%, respectively. An application of EM Farma contributed to a significant increase in seed germination capacity at both the dates compared with the control and the remaining products. No significant differences in the number of germinated seeds counted after 5 and 10 days following EM application were found for cv. Merlin only. The highest number of germinated seeds at the logistic curve inflection point was observed for all the cultivars treated with EM Farma, their germination rate ranging from over 7 to 19% per 24 hrs.

Flower or fruitlet thinning is one of the cultural practices used for improving the fruit quality and regulation of yield. The effect of ATS (FloreduX), 6-BA (MaxCel) and metamitron (Brevis) on yield and some fruit characteristics of apple trees cv. Šampion/ M.9 T337 was evaluated. Chemical thinning agents were applied alone, as subsequent spraying or as a tank mixture. Due to the possibility of damage to flowers by the announced frosts, a preparation containing sea algae – Goëmar was added in some treatments. Thinning with only MaxCel resulted in an excessive reduction of the total yield expressed in the number of fruits and their mass, but using MaxCel after flower thinning with Floredux gave very good results. The total yield expressed in kg/tree was even bigger than in the control, but the share of fruits with diameter above 7.5 mm was much better. The most promising method of thinning apple trees cv. ‘Szampion’ was the use of MaxCel+Brevis, at fruitlets diameter of 10-12 mm. The yield expressed by the number of apples on a tree was much smaller than in the control, but total yield did not differ from the total yield of the control trees. Apples in this treatment were characterised by the highest mass and length, as well as large diameters. In the fruits of this treatment, there was no significant reduction in flesh firmness relative to the control, and they had the highest dry matter content.
