BUXORO VILOYATINING TUPROQ-IQLIM SHAROITIDA AMARANT NAVLARINING OʻSISHI, RIVOJLANISHI VA HOSILDORLIGIGA TOMCHILATIB SUGʻORISH REJIMLARINING TAʻSIRI

ushbu maqoladagi raqamli natijalar dissertatsiyaning haqiqiy dala maʻlumotlari taqdim etilmagani sababli ilmiy adabiyotlar va agronomik qonuniyatlarga tayangan holda namunaviy-modellashtirilgan. Nashrga taqdim etishdan oldin ularni muallifning real tajriba natijalari bilan almashtirish talab etiladi.Abstract
Maqolada Buxoro viloyatining keskin kontinental, issiq va suv tanqis sharoitida
donli amarant navlarining oʻsishi, rivojlanishi va hosildorligiga tomchilatib sugʻorish
rejimlarining taʻsirini baholashning ilmiy-uslubiy asoslari yoritilgan. Tajriba
sxemasida uchta nav (V1, V2 va V3) hamda oʻsimlik suv isteʻmolining 60, 80 va 100%
ETc darajasiga mos sugʻorish variantlari qabul qilingan. Fenologik kuzatuvlar,
oʻsimlik boʻyi, barg sathi, quruq biomassa, vegetatsiya davri, don hosildorligi va suv
sarfi oʻrtasidagi bogʻlanishlar ikki omilli dispersion tahlil, korrelyatsiya va regressiya
usullari orqali baholangan. Namunali model natijalari 80% ETc rejimida oʻsimlikning
vegetativ rivojlanishi keskin cheklanmasdan, toʻliq sugʻorishga nisbatan suv sarfini
kamaytirish mumkinligini koʻrsatadi. V2 navida 80% ETc sharoitida don hosildorligi
2,46 t/ga atrofida shakllanib, 100% ETc variantidan farqi cheklangan, biroq 60% ETc
da oʻsish surʻati, barg sathi va biomassa toʻplanishi sezilarli pasaygan. Buxoro
sharoitida maksimal hosil emas, balki hosil va suv sarfi oʻrtasidagi maqbul nisbatni
