Abstract
Buxoro viloyatining sho‘rlangan tuproqlarida Amarant o‘simligining o‘sishi va biofaol komponentlarining shakllanishiga abiotik stresslar (suv taqchilligi, yuqori harorat va sho‘rlanish) ta’sirini o‘rganish maqsad qilindi. Tadqiqotda Xlorella vulgaris suv o‘ti “maxsus kombinatsiyalangan oziqa muhitida” yetishtirilib, turli konsentratsiyalarda Amarant urug‘iga ishlov berildi va vegetatsiya davrida tomchilatgichli fertigatsiya usuli orqali qo‘llanildi.Natijada, Xlorella v. ning maqbul konsentratsiyalarini qo‘llash orqali suv sarfi 2 baravar kamaydi, resurslar 50 % tejaldi, Amarant hosildorligi 15–20 % ga oshdi, biofaol komponentlarning shifobaxsh faolligi yaxshilandi hamda iqtisodiy rentabellik 30 % gacha ortdi.Ushbu biotexnologik yondashuv sho‘rlangan va suv tanqis hududlarda Amarant yetishtirishning samarali usullaridan biri sifatida tavsiya etiladi.References
