Abstract

Abstract A field experiment in the province of Muthanna during the summer season 2014-2015 to study the effect of three levels of humic acid on the growth and yield five genotypes of rice, the experiment carried out using a design Split Plot Design with three replications as occupied the main panels three levels of Humic acid (0, 2 and 4) ml liter −1 while genotypes occupied (IR-60819 and PR-2235 and Mchkab-1 and Jasmine and Amber-33) secondary panels. The results showed that there were significant differences between the humic acid leves, treatment 4 ml liter −1 overtook in a period of flowering (109.88 days), plant height, (99.33 cm) area of flag leaf, (38.11 cm 2 ) number of panicle 373.33 panicle/m 2 the number of grains 129.83 grains/panicle and yield grains 4.66 ton/h and there was no significant difference in grain weight, as well as the presence of significant differences between genotypes for all growth traits, as observed superiority of class dormitory -33 moral in the period of flowering, (110.88 days), Mchkab −1 in plant height, (111.34 cm) Yasmin in the flag leaf area, which amounted to 45.00 cm 2 , as it gave the class Mchkab-1 highest number of Panicles totaled 400.00 Panicles/m 2 , and the superiority of product was Jasmine and averaged 145.11 grain/Panicle, and the superiority of genotype RP -2235 average grain weight of 20 mg were given a The interaction (4 × Mchkab −1 ) higher average plant height was 118.27 cm whereas given the The interaction (0× IR-60819) less than an average of 77.44 cm, either on the flag leaf area has given The interaction (4 × Yasmin) averaged 45.45 cm 2 , while given the The interaction (0 × RP-2235) below average for this trait was 30.02 cm 2 , and for yield and its components given The interaction (2 × Mchkab −1 ) the highest average number of Panicles 450.00 Panicle/m 2, while the number of grains in the deltoid has The interaction gave (2 × Yasmin) the highest average number of grains/Panicle totaled 150.00 grain/Panicle while given The interaction (4 × IR-60819) less than an average of 98.66 grain/Panicle, also was given The interaction (2 × Mchkab −1 ) yield the highest average grain amounted to 5.82 tons/h, while the The interaction gave (0 × IR-60819) less than the average stood at 3.05 tons/ha.
