Effect of Biofertilization and Some Sinai’s Flora Extracts on the Vegetative Growth and Yield of Broad Bean

Abstract

Broad bean plants (Vicia faba L.) were cultivated in two field experiments at the Experimental Station of the Faculty of Environmental Agricultural Sciences, Arish University, North Sinai, Egypt, during 2018/2019 and 2019/2020 seasons under North Sinai condition, to study the effect of soil application of some biofertilizers and foliar spray with some wild plant extracts on broad bean plants. Biofertilizer treatments contained combination of Arbuscular Mycorrhizal Fungi (AMF) + Trichoderma harzianum + Rhizobium leguminosarum. Three wild plant extracts treatments; i.e., Qeysoom Gebeli (Achillea fragrantissima L.), Harmal (Peganum harmala L.) and Mitnaan (Thymelaea hirsute L.) were sprayed on plants. Treatments were arranged in a randomized complete block design with three replicates in split plot system. The results indicated that biofertilizers had significant effected of all studied traits in both seasons. Foliar spraying of Thymelaea hirsute extract had the highest stimulation effects on spores count, root colonization, mycorrhizal status, and weight of non-active nodules, broad bean plant growth characters; i.e. stem length, number of branches per plant, leaf area, and shoot fresh and dry weight as well as both of fresh and dry weight of roots. Both of Thymelaea hirsute and Achillea fragrantissima extracts combined with biofertilizer treatment had significant effects on yield and its components (pod length, number of pods per plant, average pod weight total yield per plant, and weight of seeds per pod) in both seasons. The combination between Thymelaea hirsute and biofertilizer was the superior interaction treatment of this study.

Effect of different nitrogen forms and bio-treatments on the growth and seed yield of downy safflower (Carthamus lanatus)

“…Trichoderma is a genus of saprotrophic fungi and a widespread component of the soil rhizosphere; it has been reported to enhance plant growth and to control many of plant diseases (Colla et al, 2014). One of the wellknown stimulatory effects of Trichoderma on plants is the ability to dissolve phos phate through acidification, chelation or redox activi ty to improving the utilization by plants (Mansour et al, 2021). The benefits of Trichoderma species in stimulating plant growth can be realized via various mechanisms including boost nutrient uptake, solubi lization, sequestration of inorganic nutrients and enhancement of root hair development (Harman, 2006;Lorito et al, 2010).…”
