INTEGRATED APPLICATION OF HUMIC ACID, FLY ASH AND FERTILISER ON BIOCHEMICAL PARAMETERS AND SOIL FERTILITY

To find out the two different organic sources like humic acid (HA) and fly ash (FA) with inorganic fertilizers on green gram, a pot experiment was conducted in Alfisol. The treatments were control , fly ash @ 20 t ha^sup -1^, humic acid @10 kg ha^sup -1^, NP alone , fly ash + NP , HA + NP, Fly ash +...

Summary:To find out the two different organic sources like humic acid (HA) and fly ash (FA) with inorganic fertilizers on green gram, a pot experiment was conducted in Alfisol. The treatments were control , fly ash @ 20 t ha^sup -1^, humic acid @10 kg ha^sup -1^, NP alone , fly ash + NP , HA + NP, Fly ash + HA + NP with and without blending. Among the treatments, the combined application of HA, fly ash and fertilizer applied by blending (T10) registered higher soluble protein (203 mg/g), nitrate reductase activity (180 NO^sub 2^/g/hr) . The same treatment also recorded higher available N (228 kg ha^sup -1^), available P (24 kg ha^sup -1^) and available K (350 kg ha^sup -1^).
