Effect of Compost Tea, Cyanobacterial Strains and their Extracts on Growth and Productivity of Wheat Plant

Abstract

Applicability of compost tea, cyanobacterial strains of Anabaena cylindrica, Nostoc calcicola and their extracts for enhancing growth and productivity of wheat plant were tested under glass house conditions. Individual and mixture with doses of inorganic nitrogen were the main treatments of the presented work. Results indicated that all the tested treatments were varied significantly in their effects during the tested three growth phases of 60, 90 and 120 days from planting. Due to use of C75TNANEAE (N 75 % + compost tea + Nostoc calicola , Anabaena cylindrica and their extracts), highly significant increase in vegetative and yield growth parameters, chemical content and NPK content ( in shoot, root, straw and grains) were obtained. Biofertilizers treatments were found to have pronounced increase in the number of viable bacterial count and the N2-fixing cyanobacteria in soil. So, utilization of the cyanobacterial inoculum which containing Anabaena cylindrica and Nostoc calcicola, their extracts and compost tea in the presence of 75% dose of N for enhancing growth and yield of wheat plant and reduce chemical fertilizers usage were recommended.

Effect of Blue-Green Algae in Soils with Different Texture: (a) on Enhancement Growth and Yield of Wheat Plant

“…Also, the cyanobacteria have been saved the inorganic nitrogen application by 25% compared with recommended doses. Similarly, Afify et al (2022b) recommended that using cyanobacterial inoculum in the presence of a 75% dose of inorganic nitrogen enhance the wheat plant's growth and yield and reduce chemical fertilizer usage. Therefore, this study aimed to determine the effect of inoculation with three cyanobacterial strains and their mixture and different doses of inorganic nitrogen in two types of soil texture on the growth and yield of wheat.…”
