IMPACT OF BIOCHAR AND COMPOST ON GROWTH AND PHYSIOLOGICAL CHARACTERISTICS OF MAIZE (ZEA MAYS L.)

Résumé fourni par la source

This study was conducted to assess the influence of combined of biochar and compost application on the growth-related morphological attributes (root and shoot weights (fresh and dry), root and shoot lengths, height of plant, no of leaves, leaves areas, stem diameter), physiological (chlorophyll, proline, free amino acid, phenolic contents) of maize (Zea mays L.).The results showed that compost and biochar treatments doses considerably affected the morpho-physiological characteristics of maize.Comparing the control (B0C0, no biochar, no compost) the introduction of combined treatment (B1C1 1% biochar, 1% compost) improved root and shoot fresh weight, total weight of plant, root and shoot length, and total length of plant, number of leaves, leaves area, stem diameter and dry weight of crop.But the concentration of biochar and compost enhanced at the level of (B2C0 and B0C2, 2% biochar, no compost and no biochar, 2% compost respectively) also improved the growth characters.Furthermore, combined treatment of biochar and compost also showed impact on physiological attributes (chlorophyll contents, reactive oxygen species, total free amino acid and phenolic content) of crop.Our results showed that biochar-compost based soil practices can improve the growth of maize.
