The aim of research was to define the influence treatment methods involving application of growth biostimulators and herbicide on the total yield of edible potato. The field research was conducted in 2015-2017 in the area of eastern Poland, in Lublin Voivodship. The experiments were performed in three replications using the randomized split-block method. Examined factors were: The examined factors included: I. factor – three early cultivars of edible potato (Owacja, Bellarosa, Vineta), II. factor – treatment methods involving application of growth biostimulators and herbicide: GreenOK-Universal Pro and Asahi SL as well as their combination with the Avatar 293 ZC herbicide. The highest total yield of tubers was obtained from object 4., where prior to sprouting, mechanical treatment was used, and after the final shaping of ridges and just before sprouting the Avatar 293 ZC herbicide was applied at a dose of 1.5 dm3 ha–1, and then after sprouting the GreenOK Universal-PRO was applied three times at doses: 0.10 dm3 ha–1 – full moon-end of seeding + 0.15 dm3 ha–1 – covering inter-rows + 0.15 dm3 ha–1 – formation of flower buds (an average of 41.8 t ha–1) and from the object 5., on which mechanical treatment was used to the seeding, and after the ultimate formation of furrows before seeding of potato plants, Avatar herbicide 293 was applied in a dose of 1.5 dm3 ha–1 (total yield amounted to, on average, 40.6 t ha–1). Potato cultivars cultivated in the experiment and meteorological conditions during the conducted tests also had a significant impact on the size of the total yield. Owacja noted the highest yields (an average of 41.4 t ha–1). The largest total yield was collected in 2016 (an average of 42.8 t ha–1). A significant influence of the experiment factors on the structure of large tuber yields was also found.

The experiment studied the effect of various mulching terms of ‘Foxtrot’ tulips with wheat straw in combination with spraying of plantations with herbicides using various doses and different amounts of working liquid. The mulch was laid out just after planting and after the soil had frozen. The experiment included combinations, in which the mulch was left until the end of the growing season or removed in spring. Spraying with single (linuron 675 g·ha–1 + lenacyl 1000 g·ha–1) or double herbicide dose (linuron 1350 g·ha–1 + lenacyl 2000 g·ha–1) was made before covering the soil with mulch and also on mulch – two weeks after planting the bulbs, or in the spring after thawing the soil. Volumes of 300 dm3 and 600 dm3 of working liquid were used for spraying. Tulips covered with mulch bloomed 2–3 days later and formed longer shoots as compared to non-mulched ones. The highest yield of marketable bulbs and the first-selection ones was obtained from tulips mulched immediately after planting and sprayed 2 weeks later with herbicides used in a single dose of 600 dm3 of a working liquid. Mulching of tulips after soil freezing and removal of mulch in spring adversely affects the number and weight of commercial bulbs. The lowest yield was obtained in combinations, in which the mulch was not used. The use of additional nitrogen fertilization before laying out the mulch did not affect the yield of tulips. Herbicides can be used both before mulching and after covering the plantation with mulch. It is not necessary to increase the dose of the agent and the amount of water.

The recent experiment was conducted to assess the effect of herbicide (quizalafop-p-ethyl) on growth, photosynthetic pigments, enzymes and yield of Black gram (Vigna mungo L.) during the summer season 2013-2014. This experiment comprised black gram (variety ADT 3) and different concentrations of herbicide (quizalafop-p-ethyl) treatments compared with control. Reduction in growth, photosynthetic pigments, enzymes and yield parameters were observed with 0.5 % herbicide application followed by 1 %, 1.5 % and 2 %, out of all treatments 0.5 % shows least reduction. Thus, 0.5 % herbicide application is the safest way for weed control in Black gram field as it showed least adverse effect on growth, photosynthetic pigments, enzymes and yield of crop when compared with other treatments.

In vitro plant tissue and cell cultures were used to study herbicide effects on growth, selected metabolic activities and other phenomena. The effect of abiotic elicitors, two newly synthesized substituted amides of pyrazine-2-carboxylic acids (synthesized at the Department of Pharmaceutical Chemistry and Drug Control, School of Pharmacy in Hradec Kralove), on the flavonolignan accumulation in callus and suspension culture of Silybum marianum (L.) Gaertn. was investigated. The compounds markedly influenced production of flavonolignans in an in vitro culture. Particularly after the elicitation with a solution of compound 3-methylamide 5-tert-butylpyrazine- -2-carboxylic acid at a concentration of 3.71x10-7 moll-1 and within 72 h of elicitation, an increase in flavonolignan production by 893 % in suspension culture versus control took place. The flavonolignan accumulation in callus culture after the elicitation with a solution of 5-brom-2-hydroxyphenylamide of 5-tert-butyl-6-chloropyrazine-2-carboxylic acid was also increased by about 1039 % (24 hour elicitation and concentration of 2.59x10-4 moll-1 ).
