Germination of Soybean Seeds treated with Sources and doses of Lithium for Agronomic Biofortification

Abstract

Lithium is a chemical element, symbol Li, this element can be new strand of world agriculture. The agronomic Biofortification of soybeans can be beneficial to the entire production chain that involves, because this practice can lead to an increase in the average productivity of culture in soils naturally poor, reversing the current picture of stagnation in productivity the last 10 years. Additionally, the producer of grains will benefit from adding value to the final product and the consumer will benefit by purchasing a product with higher Li content. Treatments were arranged in a completely randomized design (DIC), with three repetitions. The twelve treatments were arranged in a factorial scheme 2 x 6. The first factor is regarding the two lithium sources (Li2SO4 e LiOH) and the second factor refers to five doses of lithium in their fonts used (0; 20; 40; 60; 80 and 100 mg dm−3). Soybeans have had a positive effect on germination with the use of doses and sources of lithium compared with the witness, but the germination percentage was less than 65% well below the expected, which shows that the lithium in large doses can be harmful for the germination of seeds.
