Xorazm viloyatining sug‘oriladigan allyuvial o‘tloqi tuproqlari sharoitida olib borilgan dala tajribasida don
uchun yetishtirilgan makkajo‘xorida qo‘llanilgan mineral o‘g‘itlarning agronomik samaradorligi mineral o‘g‘itlar N150P75K50,
N200P100K70 va N250P125K85 kg/ga me’yorlarda ishlatilganda nisbatan yuqori bo‘ldi. Ekinda ishlatilgan mineral o‘g‘it me’yori
ortishi bilan azotli, fosfor va kaliy faktorining samaradorligi (PFP - Partial factor productivity) ko‘rsatkichi pasayib bordi.

В полевом опыте с кукурузой на орошаемых аллювиальных луговых почвах Хорезмской области срав-
нительно высокая агрономическая эффективность минеральных удобрений достигнута при использовании N150P75K50,
N200P100K70 ва N250P125K85 кг/га. Показатели PFP (Partial factor productivity) азота, фосфора и калия снижались с возрас-
танием норм вносимых минеральных удобрений на культуре.

English

In a field experiment with maize on irrigated alluvial meadow soils of the Khorezm region, a comparatively high
agronomic efficiency of mineral fertilizers was achieved using N150P75K50, N200P100K70 and N250P125K85 kg/ha. The PFP (Partial
factor productivity) of nitrogen, phosphorus and potassium nutrients decreased with an increase of mineral fertilizers rates
applied to the crop.
