Abstract
Two field experiments were conducted at Sakha Agricultural Research Station,Kafr El-Sheikh Governorate , Egypt, during  2018 and 2019 seasons.to to investigate the effect of different proportions of nitrogen rates with foliar potassium and Zinc their combined effect on growth and yield components .The treatments i.e.,45kgN/fad ,60kgN/fad,45Kg N/fad+spray with 2% K2O,45Kg N/fad+spray with 2 % Zn, 45Kg N/fad+spray with 1% K2O+1%Zn, 60 kg N/fad+spray with 2 % K2Oand 60 kg N/fad + spray with 2 % Zn, 60kg N/fad+spray with 1% K2O+1%Zn .The used variety was Sakha 107.The experiments were performed in Randomized Complete Block Design with four replications.The collected data include  physiological traits, yield attributes yields and grain quality characteristics. The main obtained results are summarized as following all mistuned traits were significantly and pristinely  responded to tested nitrogen treatment combined with foliar spray of  K2O, Zn mixture in both study seasons .The highest means of  dry matter, leaf area index ,crop growth rate, net assimilation rate , panicle number/m2, panicle length, panicle weight,filled grains numbers/panicle ,1000 grain weight. Grain, and biological  yields and  grain content of carbohydrates,crude protein and amylase were produced when rice plants received 60kgN/fad.+ mixture spray of K2O,Zn  at 1% for each.The grain quality showed the same pattern of above mentioned traits. It could be concluded  that  high growth, yield attributes, grain yield and grain quality traits, as well as  physiological parameters could be approached by apply 60kg N/fad along with  foliar spray of K2O, Zn mixture twice at 15 and 30 days after transplanting
