Ushbu tadqiqot O‘zbekistonda qishloq xo‘jaligi mahsulotlarini prognozlashni maqsad qiladi. Tadqiqot uchun ma’lumotlar O‘zbekiston Respublikasi Milliy statistika qo‘mitasidan olingan. Tadqiqot 2010-yildan 2024-yilgacha bo‘lgan 15 yillik davrni qamrab oladi. Mazkur ishda ayrim tanlangan qishloq xo‘jaligi mahsulotlari bo‘yicha Box–Jenkins metodologiyasi, ya’ni Avtoregressiv integrallashgan sirpanma o‘rtacha (ARIMA) modeli qo‘llanildi. Metodologiya talabiga ko‘ra yetarli hajmdagi kuzatuvlar zarurligi inobatga olinib, 10 turdagi qishloq xo‘jaligi mahsulotlari tanlab olindi. Modelning barcha muhim bosqichlari tizimli ravishda qo‘llanilib, 2025-yildan boshlab keyingi 5 davr uchun dinamik prognoz amalga oshirildi. Turli model tanlash mezonlari, jumladan tuzatilgan determinatsiya koeffitsienti (Adj R²), eng kichik AIC qiymati hamda eng past MAPE ko‘rsatkichlari asosida modelning aniqligi tasdiqlandi. Natijalarga ko‘ra, mahsulotlar orasida eng past Akaike axborot mezoni (AIC) qiymati arpa mahsulotiga to‘g‘ri keldi, eng past o‘rtacha mutlaq foiz xatolik (MAPE) ko‘rsatkichi esa karam mahsulotida kuzatildi.
