The thesis, entitled “The Effect of Soil Fertilization with Seaweed and Spraying with Tekomine Max on the Growth and Yield of Maize (Zea mays L.)”, was presented by the student Sarour Khalid Samawi and consisted of seven chapters: Abstract, Introduction, Literature Review, Materials and Methods, Results, Conclusions and Recommendations, and References.
The aims of the thesis were:
- To determine the optimal concentration of seaweed that yields the best growth and production of maize.
- To determine the optimal concentration of Tekomine Max that results in the highest vegetative growth and grain yield.
- To investigate the interaction effect between seaweed and Tekomine Max on improving growth and yield traits.
Based on the obtained results, the student recommended the following:
- Seaweed showed a clear effect in increasing the number of grains per ear and improving yield by reducing the negative impact of high temperatures on pollination and fertilization during the spring season.
- The highest level of seaweed application, A3 (12 kg ha⁻¹), significantly improved plant growth and yield.
- Foliar spraying with Tekomine Max at the N3 treatment (3 ml L⁻¹) had a significant positive impact on most studied traits.
- The interaction between the two factors (seaweed and Tekomine Max) largely aligned with the effects of each factor individually. The combination (A3 × N3) excelled in leaf area (a vegetative growth trait), and also outperformed in yield components such as ear length and ear weight. Meanwhile, the combination (A2 × N3) was superior in traits such as 500-grain weight and total grain yield.
