Annotatsiya. Maqolada Farg‘ona viloyatining o‘tloqi-saz tuproqlari sharoitida moshning “Baraka” navida barg sathining shakllanishi uch xil urug‘ ekish muddati (10–15 iyun, 20–25 iyun, 1–5 iyul) va olti xil ekish sxemasi (60x5-1, 60x10-1, 60x15-1, 76x5-1, 76x10-1, 76x15-1) sharoitida o‘rganilgan. Natijalar korrelyatsion va regression tahlil usullari bilan baholangan. Ko‘chat qalinligi ortishi bir tup o‘simlikdagi barg sathini keskin kamaytirgani holda (r = –0,951), maydon birligidagisini oshirgani (r = +0,609) aniqlangan. Qator oralig‘ining (60 va 76 sm) ta’siri ko‘chat qalinligi hisobga olinganda ishonarsiz bo‘lgan (p = 0,69), ya’ni barg sathini qator kengligi emas, maydon birligidagi o‘simliklar soni belgilaydi.
