Effect of Mineral, Organic and Bio-Fertilizer on Growth and Yield of Sunflower

Abstract

A field experiment was conducted in Al-Mussaib/ Al-Taheria project during the summer of 2020. A factorial experiment carried out by three factors according to the randomized complete block design RCBD to study the effect of mineral, organic and bio-fertilizer on growth and yield of sunflower. The study included two levels of NPK mineral fertilizer (without fertilizer, mineral fertilizer half the fertilizer recommendation) and two levels of organic fertilizer (without organic fertilizer, and Organic fertilizer). Three methods of bio-fertilizerd addation by used as Bio Health (Control without fertilizer, bio-fertilizer of soaking the seeds, and injecting the soil with Bio Health), For the second level seeds were soaked and mixed well with the bio-fertilizer before planting, the third level the plants were injected with Bio Health. Seeds flame cultivar cultured in June 2020.  Results of the experiment showed that there were significant differences between the means of the studied traits in the mineral’s presence, organic and bio fertilizer process, and mineral fertilizer gave the best mean for all traits except for seed yield The organic fertilization was the significant, as it reached 179.83 cm, 3693.20 cm and 23.62 leaves. plant ^-1, 23.93 cm and 64.74 g for plant height, leaf area, number of leaves, disc diameter and weight of 1000 grains compared to the control treatment, which amounted to 160.33 cm, 2315.20 cm and 18.37 leaves. plant ^-1, 19.53 cm and 56.88 g ,respectively. The interaction between mineral and organic fertilizer was significant in the means amounted to 190.50, 2.72 cm and 1.47 ton/ha for plant height and seed yield, respectively, and the triple interaction was significant for all plant traits.
