| Abstract | ||
| To study the best combination foliar fertilizers application N and K on yield and some yield component of rice cv .Anbar - 33 , a field experiment was conducted at the Agric . Res. Station Mishkhab , during 1995-1996 seasons, the design of the experiment was according to RCBD with 3 replications. There were 17 treatments, one of these was the check treatment (soil application ) was a combination of 160) N40 + P +120 K ) Kg .ha-1 and the other 16 treatments was applied as foliar treatments as well as added 1/4 from the check treatment N and K quantities with 60 Kg P .ha-1 to the all foliar treatments in which there were four levels of N (0 , 10 , 17.5 , 25 ) Kg .ha-1 and P ( 0 , 10 , 15 , 20 ) ) Kg . ha-1 . The results showed that the suitable N- foliar fertilization treatment was 17.5 kg N.ha-1 (N2) which caused significant differences in biological rice yield and grain yield of the two seasons .The mean increased to about 14.3 and 20.7 % for biological rice yield and 11.0 and 22.5 % for grain yield compared with the water foliar (N0 ) and N1 (10) kg N. ha-1- respectively.Using K- foliar fertilization treatment ( K2 ) caused significant differences in biological yield ,and grain yield the mean increased to about 9.5 and 14.6 % for biological yield and grain yield to about 9.8 and 20.0 % compared to the water foliar (K0) and 10 Kg K.ha-1- (K2) respectively. The application of (17.5 N + 20 K ) kg.ha-1 significantly increased biological yield 12432 Kg/ha , rice grains yield 4138 Kg/ha , Number of panicles 236 and Number of grains 180 compared with the other foliar treatment, While no significant differences recorded in the other plant parameters ,this treatment also had increased effects compared with the soil application treatment. | ||
