Efficacy of Application of Biostimulants Based on Non-pathogenic Microorganisms when Growing Okra in Arkansas

The results of the experiment on the cultivation of okra vegetable crops in a farm in Osceola, Arkansas, USA using innovative biostimulants based on non-pathogenic microorganisms are presented. It is shown that the use of biostimulants contributed to a significant improvement in the morphological characteristics of plants, such as plant height, the number of side branches, leaves, fruits. In the green fruits of okra, the content of vital elements-nitrogen, sulfur, potassium, and especially iron, zinc, copper, magnesium and phosphorus-increased compared with the control variant, while the content of nitrates was significantly reduced, which suggests that biostimulants studied based on non-pathogenic microorganisms are promising.
