AMMI Analysis of the Effects of Different Insecticidal Treatments against Agrotis spp. on the Technological Yield from Sugar Beet

Abstract

The aim of this study was to analyze the effects of different variants of insecticidal treatment against Agrotis spp. caterpillars on the technological yield from sugar beet using the AMMI (Additive Main Effect and Multiplicative Interaction) model. Data for the analysis of sugar beet yield and different insecticidal treatments were obtained from a trial in Winna Góra between 2011 and 2018. White sugar yield was estimated for each variant of treatment, and it was found to be directly proportional to the root weight and polarization. The content of potassium in molasses had an inversely proportional effect on the sugar yield in the variant of treatment based on phenological observations with calculated heat sums, as well as in controls. The content of α-amino-N had an inversely proportional effect on the technological yield of sugar for each variant of tested chemical treatments. The content of α-amino-N had a statistically significant effect on the sugar beet yield for all tested experimental combinations. AMMI analysis used to estimate the interaction of treatments based on environmental conditions showed the additive effect of the applied treatments on the quality parameters of white sugar yield from sugar beet. These effects were demonstrated for polarization and the content of sodium in molassigenic substances. Regarding the AMMI model, the results of the analysis of variance showed a significant interaction between treatment and year for all considered characteristics in the experiment.

A comparative study on single and multiple trait selections of equatorial grown maize hybrids

“…Similar applications of AMMI and GGE biplot have also been investigated in various biotic stress environments, including rice-blast pathosystem (Mukherjee et al, 2013), Agrotis spp. Cutworms vulnerable areas (Bocianowski and Wielkopolan, 2022), the response of cassava to various pests and diseases such as brown streak disease (Pariyo et al, 2015). Fotso et al (2018) conducted a study that investigated the response of cassava to multiple pests and diseases, utilizing AMMI and GGE biplot to evaluate the impact of these biotic stresses on cassava growth and development.…”

Insecticidal activity of Bacillus thuringiensis towards Agrotis exclamationis larvae–A widespread and underestimated pest of the Palearctic zone

“…Agrotis exclamationis causes significant losses every year [12], and very often occurs together with cutworm larvae of other closely related species i.e., Agrotis segetum [5,6,11,13]. For example, in Poland the cutworm caterpillars can damage between 2 and 30% of the yield, depending on the crop [14][15][16].…”
