Abstract
Application of biochar to agricultural soils is mostly used to improve
soil fertility. Experimental treatments were comprised of two factors: i) drought at
two level, i.e., 80% and 40% water holding capacity (WHC) which was maintained
on gravimetric basis ii) three levels of biochar i.e., control, 2 t ha
-1 and 4 t ha
-1
added to soil. Experimentation was done to examine potential of biochar
application to enhance the growth attributes, water relations, photosynthetic
pigments and antioxidants activities in maize (
Zea mays L.) seedlings. Results of
study revealed that biochar application increased the growth qualities (total
seedlings biomass, dry weight of shoot and root, shoot length and root length). In
addition; contents of photosynthetic pigments (chlorophyll a, b, a + b and a/b),
water relation (relative water contents, turgor potential, osmotic potential and water
potential) were improved significantly due to addition of biochar. Addition of 4 t
ha
-1 biochar led to significant rise activity of enzymatic antioxidant catalase (CAT),
superoxide dismutase (SOD) and peroxidase (POD) in leaf of maize seedling
sunder drought as well as well watered circumstances. However, biochar applied at
the rate 4 t ha
-1 improved the all the physiological and biochemical attributes in
maize seedlings under drought. From the results it was concluded that biochar
application is an efficient way to alleviate adverse effect of drought stress on maize.
In drought prone areas, long term impacts of biochar on production of maize and
properties of soil could be recommended as upcoming shove.
