Abstract |
The valorization of date palm wastes as bioresources has received little atten-
tion. In this context, the feasibility of date palm waste valorization through
composting and the application effects on barley plants production under
control condition was investigated. The principal requirements for compost to
be safely used are stability and maturity that refer, respectively, to the micro-
bial biomass activity’s level, germination tests, and plant growth bioassays or
phytotoxicity. Indeed, the phytotoxicity of composted date palm waste used
for seed germination and seedling growth bioassays was researched. The
finished compost values of the C/N ratio were 15.36 and 18.58%, 1.21%,
0.54%, and 0.95% for total organic carbon, N, P, and K contents, respectively.
The concentration of heavy metals and microelements were lower and met the
requirement established by national standards. Moreover, the end product
was free from harmful pathogens like Salmonella, Escherichia coli, total coli-
forms, and fecal coliform bacteria. Application of compost extract (especially
25%, 50%, and 75%) did not affect barley seed germination, stimulated hypo-
cotyl and radicle growth and is characterized by a GI exceeding 90%, demon-
strating its stability and lack of phytotoxic effect. Moreover, compost promotes
plant growth, improved physiological parameters, photosynthetic pigments,
and plant biomass. According to the results, the prepared compost especially
at the dose T3 (soil amended with 30 t/ha) increased the nutrients availability
and uptake which may be the reason for an increase in photosynthetic activity,
chlorophyll synthesis, and dry matter accumulation. Composting may well
represent an acceptable solution for disposing of date palm waste and be of
great interest to sustainable agriculture in Tunisia oasis ecosystems. |
