Rains significantly improved soil moisture under all crops, however, cool weather and slow accumulation of effective heat were not favorable for heat-loving crops, the initial development of which was very slow. On most of the sown areas, soil and air drought stopped, but in the southern regions May rainfall was not enough to stop it. In general, the condition of crops is satisfactory.
