kuzgi bugʻdoyAbstract
Maqolada kuzgi bugʻdoy navlarini parvarishlashda zamonaviy sugʻorish va mineral oziqlantirish usullarining don hosildorligi hamda sifatiga taʼsiri Oʻzbekiston va xorijiy tadqiqotchilarning ilmiy ishlari asosida qiyosiy tahlil qilindi. Sharhda egatlab va tomchilatib sugʻorish, fertigatsiya, mineral oʻgʻitlarni bosqichma-bosqich berish hamda bargdan oziqlantirish boʻyicha nashr etilgan natijalar tizimlashtirildi. Tadqiqotlar suv va azot rejimini muvofiqlashtirish hosildorlik va resurslardan foydalanish samaradorligini yaxshilashi, ammo yuqori hosildorlikka mos oziqlantirish meʼyori donning oqsil va kleykovina sifatini maqbullashtiruvchi meʼyordan farqlanishi mumkinligini koʻrsatadi. Tuproq-iqlim sharoiti va nav xususiyatlarini inobatga olmasdan tajriba natijalarini boshqa hududga koʻchirish cheklovlari ochib berildi. Ilmiy sharh natijasida nav–tuproq namligi–oziqlanish–hosildorlik–don sifati bogʻliqligini yagona agrotexnologik tizimda baholash zarurligi asoslandi.
