ABSTRACT
Field experiment was conducted to study the effect of flyash with different levels of inorganic fertilizers on productivity of paddy. Grain yields recorded by 120 kg N, 40 kg P2O5, 40 kg K2O/ha along with flyash @ 20t/ha at basal was significantly higher over inorganic fertilizers alone (120 kg N, 40 kg P2O5, 40 kg K2O/ha). Similar results were also recorded with recommended dose of fertilizers (80 kg N, 40kg P2O5, 40 kg K2O/ha) along with flyash @ 20 kg/ha but was significantly lower than higher dose of fertilizers along with flyash. Application of 75% recommended dose of fertilizers along with flyash @ 20 t/ha recorded lower yields over all other treatments.
Key words :
Fly ash, grain yield, soil properties, paddy.
