Annotatsiya. Mazkur maqolada g‘o‘zani yetishtirishda qo‘llaniladigan turli sug‘orish usullarining suv sarfi va agrotexnik samaradorligini baholashning ilmiy-uslubiy jihatlari yoritilgan. Tadqiqotda egatlab, tomchilatib va diskret sug‘orish usullarining suvdan foydalanish darajasi, tuproq namligining ildiz qatlamida taqsimlanishi, sug‘orish me’yorlari, mehnat va energiya sarfi hamda g‘o‘za hosildorligiga ta’siri qiyosiy tahlil qilinadi. Sug‘orish texnologiyasini tanlashda faqat berilgan suv miqdorini emas, balki suvning o‘simlik tomonidan samarali o‘zlashtirilishi, tuproq namligining maqbul darajada saqlanishi va agrotexnik tadbirlarning o‘z vaqtida amalga oshirilishi muhimligi asoslanadi. Olingan natijalar suv resurslari cheklangan sharoitda g‘o‘za yetishtirish samaradorligini oshirish, sug‘orish suvini tejash va hosildorlikni barqarorlashtirishga xizmat qilishi mumkin.
