Özet:

 


Application of chemical fertilizers besides
economic concerns has been a reason of environmental and ecosystem degradation,
so sustainable organic agriculture is becoming popular in researches and among
farming communities. Phosphorus holds second position after nitrogen among
macronutrients required for better plant growth and is needed in higher
amounts. Meeting this high phosphorus input for better crop yields causes environmental
problems like eutrophication, so phosphorus solubilizing bacteria (PSB) and plant
growth promoting rhizobacteria (PGPR) are being emphasized to utilize
phosphorus fixed in soil layers. This study was carried out to evaluate the effect
of PSB on plant growth, soil biological properties including enzymes and soil
respiration. Treatments including control, 50 mg kg-1 nitrogen, 50
mg kg-1 nitrogen and 12 mg kg-1 phosphorus applications
reduced dosage of nitrogen 25 mg kg-1 with PGPR and 25 mg kg-1 nitrogen
along with 0.12 g raw phosphate and PGPR. Results indicated that plant
parameters like above and below ground plant biomasses (fresh and dry weight),
plant nitrogen and phosphorus content were significantly enhanced in all the
treatments when compared with the control. While soil pH in rhizosphere
significantly increased with the treatments, bulk soil pH decreased with PGPR
treatments when compared with all other treatments. EC values in rhizosphere
and bulk soils were not significantly influenced with the treatments. Rhizospheric
and bulk soil showed high amount of N, P and organic matter in PGPR treatments.
Alkaline phosphatase and β-glucosidase activities were found significantly
higher in the last treatment than the other treatments. Basal soil respiration
was interestingly found higher in control soil but did not differ statistically
from the other treatments. Concluding, application of PGPR with lower amounts
of chemical fertilizers can reduce the use of chemical fertilizers and has also
potential of improving soil health in long term aspects.
