Abstract
The experiment carried out in this field study was between at theAICRP Research Farm in the outward-bound farm of the College of Agriculture, Indore. Indore is a small city in the western part of Madhya Pradesh, Central India, situated on the Malwa Plateau. An experiment was conducted with three replications by using different combination of N, P levels and crop residues in RBD design. Experiment field was medium to black soil with pH of 7.63 and medium in organic carbon 0.58%. The soil was low in available nitrogen (208.0 kgha-1) medium in available phosphorus (21.0 kgha-1) and high in potassium (585 kg ha-1) and divided into gross plot size of 10 x 7.2 m2 and a net plot size of 9 x 6.4 m2, respectively. During crop harvest four different depths were used to gather the soil samples: 0–10, 10–20, 20–30, and 30–40 cm. All the collected samples are examined separated for Dehydrogenase, Urease enzyme, Acid & alkaline phosphate, Arysulphatase activity. The finding showed that maximum soil DHA, Urease, Acid & alkaline phosphate, Arysulphataseactivitywas observed with the application of treatment T6 treatment (FYM 6 t ha-1 + N20 P13.
Keywords: Acid phosphate, alkaline phosphate, arysulphatase activity, dehydrogenase (DHA), urease enzyme
