Abstract

This study highlights the effect of a biostimulant based on Trichoderma, indigenous antagonistic fungus from the region of Touggourt, on the development of a local variety of corn. This study was conducted at the experimental station of National Institute of Agronomic Research (Sidi Mehdi, Touggourt) as a complete randomaize block designe. The examined agro-morphological parameters showed that the application of this bioproduct stimulates vegetative growth of the plant. Besides, better germination and earliness of seeds. The results showed more interesting values were obtained in the treated plots (height = 135.9 cm, diameter = 28.9 mm, surface of leaves = 318 cm2, Pan = 10.2 panicles/plant) compared to those of the controls (height = 98.6 cm, diameter = 23.7 mm, surface of leaves = 260.4 cm², Pan = 7.4 panicles/plant). Statistical analyzes confirmed the existence of a very highly significant difference between treated and control subjects.

Highlights

In Algeria, corn production has dropped considerably with values of 3687 and 2634 tons recorded respectively in 2016 and 2017 [1]

Tested biostimulant appears to have a significant effect on diameter of treated plants that is of 28.9 mm and only 23.7 mm for the one of control

Summary

Introduction

In Algeria, corn production has dropped considerably with values of 3687 and 2634 tons recorded respectively in 2016 and 2017 [1]. Trichoderma harzianum species have been known as biological control agents that antagonize phytopathogenic agents as well as their biofertilizing ability to stimulate shoot and root growth, to produce antibiotics and promote plant defense mechanisms [6,7,8]. These stimulation products are sometimes called alternative insofar as they are differentiated by their indirect action through the plant or the soil [9]. This study comes to evaluate the potential of a biostimulant made by some strains of indigenous fungus, from the southeastern Algeria, of Trichoderma genus on the performance of a local variety of corn
