Mazkur maqolada za’faron (Crocus sativus L.) o‘simligini Xorazm viloyatining arid agroekologik sharoitiga introduksiya qilish va uning morfo-fiziologik javoblarini kompleks baholashning ilmiy-metodik asoslari yoritiladi. Tadqiqot konsepsiyasi fenologik kuzatuvlar, morfometrik o‘lchovlar, barg suv holati, xlorofill va fotosintetik faollik ko‘rsatkichlarini birgalikda tahlil qilishga asoslanadi. Xorazm hududida yuqori yozgi harorat, yog‘ingarchilikning kamligi va tuproq sho‘rlanishi qishloq xo‘jaligi ekinlari uchun muhim ekologik cheklovlar hisoblanadi [1]. Xalqaro tadqiqotlar za’faronning sho‘rlanish va suv tanqisligiga fiziologik javobi sug‘orish rejimi hamda ekish usuliga bog‘liqligini ko‘rsatgan [2,3]. O‘zbekiston sharoitida Crocus sativus ning biologik, morfologik va anatomik xususiyatlari ham o‘rganilgan [4]. Shu sababli Xorazm sharoitida ushbu turning fenologiyasi, vegetativ o‘sishi va fiziologik holatini birgalikda baholash hududga mos agrotexnologik yondashuvlarni ishlab chiqish uchun ilmiy asos yaratishi mumkin. Maqolada hali yakunlanmagan tajriba natijalari raqamlar bilan ifodalanmagan; natijalar bo‘limi keyingi dala va laboratoriya o‘lchovlari bilan to‘ldirilishi nazarda tutiladi
