Abstract:
Salinity is a major abiotic stress that affects crop production throughout the
world. New strategies for plant adaptation with soil affected by salinity are needed.
Biochar may be an effective management tool. Biochar is a charcoal-type material
manufactured specifically for use as a soil amendment in agriculture. It is produced by
pyrolysis of biomass under low or anaerobic conditions. The following experiment
includes the preparation of biochar using rice husk biomass and then characterization
of biochar through different physical and chemical analysis. Pot experiment is set up
for eight treatments, treatment without biochar is set as control, 2% biochar is
introduced in three different levels of salinity. This research is designed to evaluate
the ameliorative effect of 2% biochar application on growth parameter of wheat crop
under different levels of salinity stress i.e., 50ppm, 100 ppm and 150 ppm NaCl
solution. Biochar application had positive effect on all observed treatments with
salinity levels (50ppm, 100ppm, 150ppm) compared to the respective unamended
treatments and the addition of 2% biochar in the treatment with concentration of
150ppm provided with best possible results.
