Research aim and objectives:
he purpose of the study is to evaluate the technology of planting grain crops and water saving in planting with water-retaining hydgogel.
- the influence of hydrogel on the growth and development of plants, productivity and quality of the crop is evaluated;
- the amount of water used in relation to the gross yield of agricultural crops and water saving compared to traditional methods is studied;
- evaluation of the economic efficiency of the agrotechnological methods studied and determined as a result of the conducted research;
- the application of hydrogel to the soil in the cultivation of grain crops consists in the development of a high-yielding, economically efficient cultivation technology by applying the standards of water consumption.
Research object:
as Southern Agricultural Research Institute and hydrogel material was obtained.
Results and their novelty:
for the first time, in the conditions of irrigated pale gray soils of Kashkadarya region, water saving was studied when sowing grain crops with water-retaining hydgogel;
for the first time, the amount of water used in the cultivation of grain crops in the conditions of irrigated light gray soils of Kashkadarya region and water saving compared to traditional methods were studied;
studied the effectiveness of water consumption using hydrogel in grain crops;
optimal water-retaining hydgogel standards, which ensure high yield of spiked grain crops depending on the increase of effective moisture reserves in the soil, were determined and economic efficiency was evaluated.
Practical and scientific value:
The practical importance is to determine the laws of increasing effective moisture reserves by applying water-retaining hydgogel to the irrigated pale gray soils of Kashkadarya region, the amount of water consumed in relation to the yield in the cultivation of grain crops in general, and water compared to traditional methods. enriches our knowledge about water conservation and also serves to develop methods of rational use of water and its conservation.
The practical significance of the research results is that the use of water-retaining hydgogel at different rates in the cultivation of grain crops on farms in the conditions of irrigated light gray soils of Kashkadarya region increases the effective moisture reserves in the soil and the growth of grain crops. , was explained by the development and development of the rules for the use of optimal water-retaining hydgogel, which ensures high productivity. Also, the effect of water-retaining hydgogel on the increase of effective moisture reserves in the soil with the use of water-retaining hydgogel at different rates was studied in the cultivation of grain crops, which reveals the scientific nature of the research.
