Abstract
Mazkur tadqiqotda 2023–2025-yillarda unabi (Ziziphus jujuba Mill.) navlarini “Melkoplodniy kisliy 1” va Ziziphus acidojujuba payvandtaglarida yetishtirishda turli mineral o‘g‘itlash me’yorlarining iqtisodiy samaradorligi baholandi. Tajribada o‘g‘itlanmagan nazorat hamda N₆₀P₃₀K₁₅, N₁₂₀P₉₀K₃₀, N₁₆₀P₁₂₀K₄₀ va N₂₀₀P₁₅₀K₅₀ variantlari qiyoslandi. Hisob-kitoblar qo‘shimcha xarajat–qo‘shimcha daromad usulida amalga oshirildi. Har ikkala payvandtagda ham eng yuqori iqtisodiy natija N₁₆₀P₁₂₀K₄₀ me’yorida qayd etildi. “Melkoplodniy kisliy 1” payvandtagida ushbu variant 32,12 mln so‘m/ga qo‘shimcha sof daromad va 215,6% rentabellikni, Z. acidojujuba payvandtagida esa 25,36 mln so‘m/ga va 195,0% rentabellikni ta’minladi. O‘g‘it me’yorini N₂₀₀P₁₅₀K₅₀ gacha oshirish hosildorlik va iqtisodiy qaytimning pasayishiga olib keldi.References
