The impact of soil drought on the formation of organs and productivity of vegetable pea

The article describes the impact of soil drought on the formation of vegetative and generative organs (flowers, beans and grains) in vegetable pea, as well as on productivity. As a result of the research, it was determined that the soil drought had a negative impact on the formation of leaves, flowers, beans and grains in vegetable pea, leading to a decrease in their number, as well as a reduction in leaf surface area. It was also found that, the length of the beans was shortened and the width was slightly increased due to the drought, which led to the enlargement of the grain and an increase in the weight of 1,000 seeds. The results of the study showed that the first beans appeared in the non-irrigated drought field 15 days earlier than in the irrigated area, and the plant completed its growing season faster, which protects the plants from the destructive impact of soil and air drought.  Soil drought also has a significant impact on the structure of the crop - the number and size of beans per plant, the weight and number of grains in beans, the mass of 1000 grains, as well as productivity.
