Stimulation of Chilli and Groundnut Plant Growth by Crude of Trichoderma SPP

Abstract

Rhizosphere filamentous fungi of the genus Trichoderma, a dominant component of various soil ecosystem mycobiomes, are characterized by the ability to colonize plant roots. Detailed knowledge of the properties of Trichoderma, including metabolic activity and the type of interaction with plants and other microorganisms, can ensure its effective use in agriculture. The growing interest in the application of Trichoderma results from their direct and indirect biocontrol potential against a wide range of soil phytopathogens. This study evaluates the impact of different concentrations of crude on the germination, growth, and yield of Capsicum annuum (chilli) and Arachis hypogaea (groundnut). Growth measurements, including root and shoot length, showed maximum development under 50% crude treatment, with chilli reaching 29.2 cm and groundnut 34.46 cm in root length. Yield parameters, including fruit count and weight, were also highest under 50% crude treatment, suggesting improved physiological and metabolic activity. These findings highlight the potential of crude-based organic treatments as sustainable alternatives to synthetic fertilizers, promoting enhanced crop productivity. Future research should focus on biochemical mechanisms underlying these effects to optimize crude application in agricultural practices is under progress.
