Abstract
Maqolada sarept xantali (Brassica junceae Czern.) ning “Nika” va “Yunona” navlarini poya balandligiga urug‘larni ekish oldidan, o‘simlikni to‘pbarg va to‘pgul hosil qilish davrlarida stimulyatorlar bilan ishlov berishning ta’siriga oid ma’lumotlar keltirilgan. Xantal navlari urug‘larini ekish oldidan Uzgumi stimulyatorini urug‘ga ekish oldidan 700 ml/t, to‘p barg hosil qiqlish davrida 200 ml/ga, to‘pgul hosil qilish davrida 400 ml/ga va Fitovak stimulyatorini ekish oldidan urug‘ga 300 ml/t, to‘p barg hosil qilish davrida 300 ml/ga, to‘pgul hosil qilish davrida esa 400 ml/ga me’yorlarda qo‘llanilgan variantlarda yuqori natijalar kuzatilib, o‘simlikning bo‘yi poya hosil qilish fazasida 44,5-45,0 sm, shonalash fazasida 84,6-85,3 sm, gullash fazasida 114,1-114,8 sm, qo‘zoqcha hosil qilish fazasida 138,3-139,1 sm va pishish fazasida 143,6-144,0 sm ni tashkil etganligi aniqlangan. Yunona navida esa poya hosil qilish fazasida 45,3-46,1 sm, shonalash fazasida 86,7-87,0 sm, gullash fazasida 115,8-116,7 sm, qo‘zoqcha hosil qilish fazasida 140,6-141,4 sm va pishish fazasida 145,2-145,8 sm ni tashkil etgan.
