Syrdarya region of the Republic of Uzbekistan mainly grows cotton, winter wheat, rice, corn, oats, and barley. Each type of plant requires a certain amount of moisture, nutrients, temperature, solar energy, and other factors.
Although the plants listed above are resistant to a certain level of mineralized water resources, improper use of ditch water will worsen the reclamation condition of the soil.
Therefore, the study and modeling of the impact of irrigated water quality on productivity are one of the pressing issues.
To parameterize the CropSyst model, the plant under study is grown under stressless conditions, and all the observed parameters are included in this model. For example, it requires regular and timely irrigation, proper care, adequate fertilizer application, soil reclamation management, and phenological observations during each growing season.
In the next validation phase, the selected replanting mung bean is grown under altered conditions, such as changing the irrigation regime or applying different amounts of fertilizer. These modified parameters are entered into the model and constructed by comparing the results shown in the model with the results obtained in practice. If the results shown in the model are the same as the results obtained from the field experiment, then this model is considered to be correctly parameterized. In the application section, we will again test the model and recommend it to farmers for use.
