Response of the Weight of A Thousand Seed With Inoculation With Nitrogen-Fixing Bacteria In Soybean Cultivated in Soil Contaminated With Copper

Abstract: Copper is a heavy metal that occurs naturally in soil and is an essential micronutrient for plant development, but high levels of copper in soil can harm agricultural production due to its toxicity, posing risks to the entire anthropogenic chain, including animals and animals. humans. Soy production has reached global relevance, manifested in domestic and export markets due to the socioeconomic value of its products and by-products in numerous applications, producing a variety of food products such as oils, milk, margarine, cheeses, sauces, proteins from texture. of soy, soy flour and meal for animal feed. The insertion of the bacterium Bradyrhizobium joponicum promotes biological nitrogen fixation and is one of the main factors in large-scale soybean cultivation in Brazil.

Key words: copper, heavy metal, Bradyrhizobium joponicum
