GERMINAÇÃO E VIGOR DE SEMENTES DE SORGO E MILHO TRATADAS COM ESTIMULANTE DE CRESCIMENTO

Abstract

Corn and sorghum are crops of significant importance for Brazilian agriculture. They are in high demand for national use, in animal and human food, and for exportation. In this sense, the use of high-quality seeds may increase the viability of crops, becoming an important ally for producers. In this sense, the objective of the present study was to verify the effects of the treatment of sorghum and corn seeds using growth stimulants containing micronutrients and amino acids on the germination and vigor of the plants. For that, there were used six doses (0, 1, 2, 3, 4 and 5 ml kg-1 of seeds) of the mixed mineral fertilizer“Agressive Desperta” and the germination test variables were analyzed to determine seedling growth and seedling dry mass. The treatment did not provide differencesin the germination percentageof corn seeds. In addition to reduction in shoot and root length and increase in corn root dry matter.In sorghum a reduction in the percentage of seed germination wasobserved, an increase in the length of sorghum seedlings related to the variables: aerial part, rootand total, and a reduction in the dry matter of the sorghum root.
