The effect of the biological addition of trichoderma, fertilizer, spraying of amino acids and natural extracts on the growth and yield of broccoli

Abstract

  factor field experiment with two factors was implemented  according to the randomized complete blocks design with three replicates during the autumn cultivation season of 2019 for the period from 15/8/2019 to 30/1/2020 in one of the private fields in Fallujah city study the effect of adding some biological fertilizers and sprinkling some nutrients on the growth and yield of broccoli .A . The first factor included terrestrial applications as follows (without application T0 and application a fertilizer recommendation T1 and application half a fertilizer recommendation + trichoderma fungus T2 and application humic acid + trichoderma fungusT3) . The second factor included foliar spray, and it includes (without spraying D0 , spraying with biozyme D1, amino acid spraying D2, and licorice Glycyrrhiza glabra extract sprayD3) . The results showed that the effect of adding some biological fertilizers and foliar spray with some nutrients to a significant increase in (plant height, leaf area, total chlorophyll in the leaves, dry weight of the vegetative group, early flowering, weight of the main flower disc, total yield of floral discs, nitrogen in the flower discs Phosphorous in floral discs, potassium in floral discs.
