FIELD: agriculture.
SUBSTANCE: method consists in determining free proline in leaves or grains before and after applying agronomic practices, with the subsequent calculation of the antistress factor which is expressed in the ratio of proline concentration before agronomic practice application to its concentration after agronomic practice application. Wherein the higher is the antistress factor, the less is the stress situation effect and the higher is the yield increase from the given agronomic practice application. The agronomic practices are represented by various tillage types in the form of single or double disking or fertilizing with nitrogen or phosphorus fertilizers or spraying with Microel microfertilizers or potassium humate.
EFFECT: method allows to increase the yield of grain crops.
