Abstrak
Nair usuli bilan sug‘oriladigan tipik bo‘z tuproqlarda fosfor adsorbsiyasi va muvozanat konsentratsiyasini aniqlash asosida uning fosforga standart talabi aniqlangan. Standart talab va g‘o‘zaning rejalashtirilgan hosilni shakillantirish uchun sarflaydigan fosfor miqdori asosida belgilangan mineral va organik o‘g‘itlar me’yorlarining g‘o‘zaning asosiy oziqa elementlarining o‘zlashtirishiga vegetativ va generativ organlarida taqsimlanishiga, hosil birligini shakllantirishiga va hosildorligiga ta’siri aniqlangan.
