Relationship of potato yield and factors of influence on the background of herbological protection

Abstract

The latest technologies for growing crops, including potatoes, are based on the use of modern mathematical models that can fairly accurately identify the impact of various factors of natural and technological nature on the object of study. Yield modeling makes it possible to adjust resource consumption indicators to obtain the maximum economic effect and minimize the negative impact on the environment. It was found that the lowest weediness of potato agrocenosis (24 pcs/m2) was formed by the complex application of Hezagard (4 L ha−1) and Panthera (1 L ha−1). The lowest level of actual weeds infestation had a positive effect on the yield of tubers – 27.6 t ha−1 (+26.6% to control) and was obtained in the variant of herbicide application. The results of correlations of potato tuber yield from factors such as weediness, density and productive moisture reserves in the arable soil layer are highlighted. It was found that the highest yield of 27.6 t ha−1 (+26.6% compared to the control) was obtained in the variant with the application of herbicides Hezagard (4 L ha−1) and Panthera (1 L ha−1). According to the results of multiple regression, it was found that the coefficient of multiple correlation is R = 0.9985, and the coefficient of determination is R = 0.997, i.e., the relationship between potato yield and experimental factors is quite close.

“…Also, glyphosate can reduce the activity of the enzyme ribulose-1.5-bisphosphate carboxylase/oxygenase (Rubisco), which is necessary for carbon fixation in the process of photosynthesis. This can lead to reduced photosynthetic efficiency and reduced plant growth and yield (Korpita & Shuvar, 2020;Soares et al, 2020) In addition, active substances such as atrazine and metribuzin have been shown to disrupt the electron transport chain in photosynthesis, leading to a decrease in energy production and photosynthetic activity (Corrêa & Alves, 2010;Shuvar et al, 2022). Certain herbicides can disrupt the electron transport chain in photosynthesis, which can lead to reduced energy production and photosynthetic activity.…”

“…Certain herbicides can disrupt the electron transport chain in photosynthesis, which can lead to reduced energy production and photosynthetic activity. For example, atrazine alters the electron transport chain, leading to reduced ATP (Adenosine triphosphate) production and ultimately reduced photosynthesis in plants (Banerjee et al, 2022;Shuvar & Korpita, 2023).…”

Study on the influence of fertilizers on the yield and quality of barley and potatoes

“…For potato plants, the temperature regime is very important, so at 10...12 0 C in moderately moist soil they sprout on the 25...27th day, at 14...16 0 C -on the 18...22 nd day. The best temperature for germinating tubers in the middle zone is 18...22 0 C. The combination of good soil moisture supply and optimal temperature during germination contributes to the accelerated emergence of seedlings [13,14]. The most favorable temperature for tuber formation is 15...20 0 C. At a temperature of 6 0 C and above 23 0 C, tuber growth is delayed, and at 26...29 0 C, tuber formation stops.…”
