How Much Water is Given per 1 Decare?
While looking for the answer to the question of how much water is given per 1 decare, it is first necessary to determine the parameters that determine the amount of irrigation water. In calculating the amount of water to be given in 1 decare, factors such as soil permeability, the vegetative period of the plant, and the evapotranspiration rate are effective. Plant water consumption is influenced by the characteristic features of the plant and the soil. In terms of the plant, these are the plant variety, plant growth stage, leaf characteristics, stomatal characteristics, and root characteristics. These are the factors affecting transpiration. The factors affecting evaporation are; sunshine, temperature, atmospheric humidity rate, wind, soil moisture rate, soil aeration, and the concentration of soil water.
While calculating the plant water consumption coefficient, 4 different periods are taken into consideration, these are;
- Initial period: In annual plants, this period covers the time from the sowing-planting date to the period where it covers approximately 10% of the soil surface.
- Development Period: This period begins with the end of the initial period and covers the period when the green parts of the plants develop rapidly.
- Mid-Season Period: The mid-season period begins with the completion of the development period. In this period, development characteristics such as flowering, maturation, and fruiting are observed more than the development of the green parts in the plant. Generally, the mid-season period ends when the first aging in the leaves and the first yellowing in the leaves begin.
- Late season period: For many plants, this is the period between the end of the mid-season period and harvest or the last harvest. For fruit trees, the time interval between the start of leaf fall and the significant reduction in the amount of green leaves can be evaluated as the late season period, while in evergreen plants, the late season period can be considered to be very short and a short time interval after the last irrigation.

Corn | 500-800 mm |
Soybean | 450-700 mm |
Sunflower | 600-100 mm |
Apricot | 550 mm |

Plant Net Irrigation Water Requirements
Plant net irrigation water requirements are tracked according to meteorological station data. These data are calculated by taking into account factors such as the amount of water the plants need, weather conditions, soil moisture, soil type, and plant type.
Meteorological station data is important for determining the amount of water plants need. These data include factors such as daily or weekly precipitation amount, humidity rate, air temperature, and wind speed. These data are used to determine the amount of water the plants need.
The net irrigation water requirement needed by plants may vary according to agricultural irrigation methods. For example, when using a surface irrigation system, the amount of water needed by plants may be higher because water is lost on the soil surface. When using an underground irrigation system, the amount of water needed by plants may be lower because it prevents water loss on the soil surface.
As a result, the net irrigation water requirement needed by plants, calculated by considering meteorological station data, may vary according to agricultural irrigation methods and is important for the healthy development of plants. Using these data, correct irrigation methods can be applied to increase productivity and protect water resources.
