Effect of Biofertilizer in Flax Yield and its components

Abstract

A field experiment was carried out in the winter season 2020-2021 in Al-Mahaweel (25 km north of babylon Governorate) in order to study the effect of bio fertilizer in flax yield and its components for several varieties of flax. A factorial experiment was applied according to a Randomized Complete Block Design (R.C.B.D) with three replications. The experiment included two factors, the first includes eight varieties of flax (Indian Variety, Giza 11, Giza 10, Sahka 5, Sahka 6, Giza 8, Syrian Variety, Thorshansity 72), The second factor, bio fertilizer includes four levels: (control, bacterial fertilization, fungal fertilization and a bacterial-fungal mixture). The following traits were measured (number of capsules per plant, number of seeds per capsules, 1000 seed weight, total seed yield, biological yield and harvest index). The results showed that Giza 10 Varity significantly superiority on other verities in all studied traits, while Thorshansity 72 Varity gave lowest means in most of the yield traits and its components. The bio fertilization also achieved a significant increase in all traits with the superiority of the fertilization treatment (Bacterial fertilizer + Mycorrhiza). The interaction between the variety and the bio fertilization was The combination (Giza 10 + Bacterial fertilizer + Mycorrhiza) achieved highest means for all studied traits, as number of capsules per plant was (76.22) capsule. plant^-1, number of seeds per capsule (9.95) seed. capsule^-1, weight of 1000 seeds (13.79) g, total seeds yield (1,681.40) kg.h^-1, biological yield (6542.70) kg and harvest index (30.87) %.
