Ushbu maqolada Samarqand viloyatining Bulung‘ur va Jomboy tumanlarida 2015-2024 yillar davomida sabzavot hosildorligiga ta’sir etuvchi asosiy agroiqlim va agrotexnik omillar ekonometrik usullar asosida tadqiq qilindi. Tadqiqotda yog‘ingarchilik miqdori, ob -havo sharoiti, sug‘orish hajmi hamda mineral o‘g‘itlar sarfi kabi omillarning hosildorlikka ta’siri ko‘p omilli chiziqli regressiya modeli yordamida baholangan. Model parametrlarini baholashda eng kichik kvadratlar usuli, modelning adekvatligini tekshirishda esa determinatsiya koeffitsiyenti, Fisher mezoni, Student tstatistikasi va Durbin-Watson mezonidan foydalanilgan. Tadqiqot natijalari sabzavot yetishtirish jarayonida hosildorlikni shakillantiruvchi omillar o‘rtasidagi bog‘lanishlarni aniqlash, ularning iqtisodiy mazmunini talqin qilish hamda qishloq xo‘jaligi resurslaridan samarali foydalanish bo‘yicha ilmiy asoslangan xulosalar ishlab chiqishga metodik asos bo‘lib xizmat qiladi. Mazkur yondashuv hududiy agroiqtisodiy tahlillarni amalga oshirish, hosildorlikni prognozlash va boshqaruv qarorlarini qabul qilishda amaliy ahamiyatga ega.Kalit soʻzlar
