Impact of applied vermicompost tea and humic acid on nodulation status, vegetative growth, and yield attributes of bean (phaseolus vulgaris l)‎ plants

Abstract EN

This work amid to investigate the beneficial effect of Rhizobium strains, vermicompost tea and humic acid and their interactions on nodulation, vegetative growth, N, P, K mineral contents and uptake and seed yield production and its components of Bean (Phaseolus vulgaris L) plants.

Results showed that application of Rhizobium leguanomis vr.

Phaseolus mixed two strains with vermicompost tea and humic acid increased vegetative growth measurements i.

e.

, plant height cm/plant, number of branches/plants, plant dry weight (g/plot), chlorophyll a, b and carotenoids, number of nodules per plant, dry weight of root nodule mg/plant, plant dry weight g/plant, seed number /plant, number of pods/plants, number of seed per pod, seed yield per plot during 2019 and 2020 growing seasons.

In the same time other different applied treatments increased these traits as compared to un treated plants but doesn't reach the highest value like the above-mentioned treatment during both seasons.
