Abstract
A factorial experiment RCBD carried out in plastic house to evaluate the effect of fertilizers containing (K+ Mg ) used by application in soil and as foliar fertilization and growth and yield of tomato (Lycopersicon Esculentum Mill ) Carmella variety planted in silty clay loam four levels of fertilizer mixture (K+Mg) ( 0+0) , (100+50) , (200+100) ,(300+150) Kg . ha -1 represented levels : S0 , S1, S2 , S3 of sulphate (%41.5 K)and magnesium sulfate (17%Mg) in soil . Feryilizerr mixture (K+Mg) was applied by soil for three times with time interval of 30 days . The first application was after 30 days of planting , and 1/3 of soil application was used as foliar fertilizer was sprayed in four levels : (0+0) , (33.3+16.6) , (66.6+33.3) , ( 100+ 50 ) Kg . ha represented levels F0 , F1 , F2 , F3 Foliar fertilizer was sprayed in four times : 1st application after 80 days of planting and repeated every 30 days . Significant increase in plant dry weight Soil application S2 and foliar application f2 caused increase in dry matter weight,.Fertilizer mixture (K+Mg) applied in soil and as foliar application and their interaction caused significant increase in K , Mg , concentration in leaves , and fruits, early.Results showed that addition potassium and magnesium increased early yield of tomato plant . . Addition of potassium and magnesium (S2 , F2 and S2F2 ) significant increased total yield of tomato plant achieved to 220.82 .
