Impact of Growth Biostimulators and Herbicide on the Content of Major Protein in Edible Potato Tubers

Abstract

New solutions which would allow for the realization of two basic objectives, i.e. production-related and environmental ones, continue to be sought in plant production. Hence, the purpose of research was to define the impact of five methods of potato field treatment with the application of growth biostimulators and herbicide on the content and harvest of major protein Solanum tuberosum L. Field experiments were carried out in the years 2015-2016 in the region of Eastern Poland (52°02'N; 23°07'E). The experiment was performed in the split-plot system in three replications. The tested factors included: I. Factor-two early edible potato cultivars (Owacja, Bellarosa), II. Factor-methods of treatment with the application of growth biostimulators: GreenOk-Uniwersal Pro and Asahi SL and their combination with Avatar 293 ZC herbicide. As a result of the carried out research, it was noted that the methods of treatment applied in the experiment had a beneficial effect on the value of tested features in comparison to the control object, treated exclusively mechanically (without the use of biostimulators and herbicide). Both in terms of protein concentration and the obtained crop of major protein, the application of mechanical treatment for sprouting of potato plants and Avatar 293 ZC herbicide at a dose of 1.5 dm 3 •ha-1 directly before the sprouting and subsequently post sprouting, triple application of GreenOK Universal-PRO bioactivator at the following doses: 0.10 dm 3 •ha-1 + 0.15 dm 3 •ha-1 + 0.15 dm 3 •ha-1 was the most beneficial. The average content of major proteins in this object amounted to 8.14% while the average protein yield-750.09 kg•ha-1 .

Yield-Forming Effects of Herbicide and Biostimulants Application in Potato Cultivation

“…Thus, there were similar trends as in the yield of dry matter and starch. Baranowska et al [2018] also showed a significant effect of herbicide and biostimulants on the yield of total potato protein. After the application of herbicides to weed potatoes, Gugała and Zarzecka [2010] noted an increase in the yield of total protein and proper protein compared to the object without chemical treatments.…”

Assessment of Bioefficacy by Using Biostimulants on Growth, Quality, and Yield of Chilli (Capsicum annum L.)

“…This can increase market value and profitability.Improved soil health can promote beneficial microbial activity in the soil, leading to improved soil health and fertility. This can create a more favorable environment for chilli crop growth [3]. There are various types of biostimulants that can be used in chilli crop production, including plant growth-promoting substances, humic substances, and beneficial microorganisms.…”
