Oʻzbekistonning Toshkent viloyati iqlim oʻzgarishi taʼsiriga sezuvchan hudud hisoblanadi. Bu hudud dunyodagi eng qurg'oqchil va suv tanqis hududlaridan biri hisoblanadi. Iqlim o'zgarishi, ayniqsa, haroratning oshishi, yog'ingarchilikning kamayishi va tez-tez sodir bo'ladigan ekstremal ob-havo hodisalari tufayli bu muammolarni yanada kuchaytiradi. AquaCrop turli xil ekinlarni, shu jumladan bug'doyni turli xil ekologik sharoitlarda modellashtirish uchun ishlatiladigan samarali vositadir. Model ekinlarning fiziologiyasi va suvdan foydalanish samaradorligini inobatga oladi, bu unga turli xil suv va harorat rejimlarida hosilni bashorat qilish imkonini beradi. Ushbu tadqiqotda AquaCrop ekin modeli Toshkent viloyatining Bekobod tumanida sinovdan o'tkazildi. Model yig'ilgan ikkilamchi qishloq xo'jaligi ma'lumotlari va iqlim ko'rsatkichlari asosida kalibratsiya qilingan. 1998-2016 yillardagi bug'doy hosildorligi ko'rsatkichlari statistik ma'lumotlar va model natijalari bilan taqqoslandi. AquaCrop ekin modeli 1998-2016 yillarda Bekobodda olingan bug'doy hosilini 4,69 ts/ga xato bilan bashorat qilish imkonini berdi. Bunda o'rtacha indikatorning mutlaq xatosi 9 s/ga, o'rtacha kvadrat xatosi 0,7 s/ga va Pearson korrelyatsiyasi 0,65 s/ga ni tashkil qildi.
