|A field experiment was conducted during the summer seasons of 2017 and 2018 to study the effect of adding Seaweed extract (Algaren) on the growth and yield components of two varieties of Rice (Oryza sativa L.). The experiment was accomplished using Randomized Complete Block Design (RCBD) in a split plot arrangement with three replicates. The study involved two varieties of Rice (Anbbar33 and Yassamen) as main treatments, while, sub plots comprised of six treatments add of seaweed extract (Algaren) and they were symbolized (T0, T1, T2, T3, T4 and T5). Results show that the variety Yassamen significantly superposed to Anbbar33 variety in all growth and yield components. Also, the adding Seaweed extract (Algaren) T5 treatment (Seed immersion in 0.2-0.3% solution before planting + first spray at stage 2-4 leaves + second spray at the branching stage) significantly gave the best results of (Number of days from planting to 50% flowering, number of days from planting to physiological maturity, number of effective branches bearing panicle. m-2, the weight of 1000 grains, grain yield, compared to T0 (non-adding plant) which gave the lowest values. The interaction between varieties and Seaweed extract showed that the Yassamen cultivar with T5 treatment significantly outperformed in all growth and yield components compared to cultivar Anbbar33 with treatment T0 (non-addition of Algaren) which gave the lowest values. From the data obtained from this study, it can be concluded that adding Algaren leads to improving the growth and yield components of varieties of rice used in this experiment.|
