“…Stanaszek-Tomal [ 50 ] shows the high resistance of fungi to unfavorable conditions. As emphasised by many authors [ 7 , 18 , 38 ], an increase in soil organic matter content (crop residues), which is a source of nutrients for microorganisms, leads to an increase in microbial abundance. Sebiomo et al [ 48 ] studied the influence of, among others, glyphosate on the populations of bacteria, actinomyces and fungi in a dose recommended by the manufacturer and found its negative impact on these microbiological parameters.…”

Purpose The use of glyphosate in agriculture raises a lot of controversy because research concerning its impact on the soil provides contradictory information. However, despite these negative opinions, glyphosate is still used in agricultural practice. Therefore, for a more complete assessment, the authors carried out research using traditional microbiological methods and a modern method of metabolic profile analysis in glyphosate-treated soil. Methods The study was carried out on the soil witch was sown with six cultivars of rapeseed. Seven days before harvest, the plants were sprayed with the herbicide. The analyses consisted in determining the number of selected groups of microorganisms, biochemical and enzymatic activity, and differentiation of the catabolic potential of soil microbial communities. Results The results showed significant changes in the analyzed parameters. Respiratory activity and ammonification processes were stimulated in the treatments with rapeseed cultivation treated with the herbicide. Changes in the enzymatic activity were generally positive. The EcoPlate assessment of microbial community catabolism showed that the highest activity was recorded in the soil sown with the cultivars Belinda, Tamarin, and Sw svinto. Concurrently, these soils were characterized by the highest correlations between rapeseed cultivar and metabolic activity. Conclusion Cultivation of specific plant varieties that reduce the negative effect of herbicides used in agriculture may be one of the methods to prevent soil degradation. In our research, Belinda turned out to be a cultivar, under the cultivation of which an increase in the activity of microorganisms was recorded most frequently compared to soil not sown with rapeseed.

Livestock production in the basins of the northern macro-region of Peru has as its primary source pastures of Lolium multiflorum L. ‘Cajamarquino ecotype’ (ryegrass CE) in monoculture, or in association with white clover Ladino variety, for feeding. The objective of this research work was the morphological characterisation, yield evaluation, and cutting time evaluation of two local genotypes (LM-58 and LM-43) of Lolium multiflorum L. in six locations. An ANOVA was performed to compare fixed effects and interaction. It was determined that the LM-58 genotype is intermediate, growing semi-erect, with a dark green colouring and 0.8 cm broadleaf, and can reach an average stem length of 46 cm, up to 1.6 cm. day−1, achieving fourth-leaf growth at 28 days under appropriate management conditions. Despite the differentiated characteristics, according to BLASTn evaluation, the ITS1 sequences showed a greater than 99.9% similar identification to Lolium multiflorum L., characterising it as such. It was determined that the LM-58 genotype outperforms LM-43, achieving a forage yield of 4.49 Mg. ha−1, a seed production of 259.23 kg. ha−1, and an average of 13.48% crude protein (CP). The best biomass yield (49.10 Mg. ha−1.yr−1) is reached at 60 days; however, at 30 days, there is a high level of CP (14.84%) and there are no differences in the annual protein production at the cutting age of 60 and 45 days. With the results of the present study, LM-58 from a selection and crossbreeding of 680 ryegrass EC accessions emerges as an elite genotype adapted to the conditions of the northern high Andean zone of Peru.
