Abstract
Ushbu sharh maqolada o‘tloqi alluvial tuproqlar sharoitida kuzgi bug‘doy hosiliga mineral o‘g‘itlar me’yorining ta’siri xalqaro maqolalar tahlili asosida o‘rganilgan. Tadqiqot natijalari shuni ko‘rsatadiki, azot o‘g‘itlari bug‘doy hosildorligini barqarorlashtiruvchi eng muhim omil hisoblanadi. O‘tloqi alluvial tuproqlarda optimal o‘g‘it me’yorlari: N - 80-120 kg/ga, P2O5 - 50-70 kg/ga, K2O - 40-60 kg/ga tashkil etadi. Uzoq muddatli dala tajribalariga ko‘ra, mineral azot qo‘llash bug‘doy hosilining yillar orasidagi o‘zgaruvchanligini sezilarli darajada kamaytiradi va barqaror hosildorlikni ta’minlaydi. O‘zbekiston sharoitida, ayniqsa Xorazm viloyati o‘tloqi alluvial tuproqlarida, ushbu yondashuvlarni joriy etish bug‘doy hosildorligini 85-90 s/ga darajasiga ko‘tarish va qishloq xo‘jaligi barqarorligini ta’minlash imkonini beradi.References
