Impact of silk reeling effluent irrigation on soil physical and chemical properties in mulberry garden

Abstract

A field experiment was conducted during 2022-2023 at Department of Sericulture, UAS, GKVK, Bengaluru to know the growth and development of mulberry when irrigated with various proportion of reeling effluent and borewell water along with recommended dose of NPK and FYM. Five treatments were laid out in RCBD with four replications. Among all the treatments application of 100 percent reeling effluent for irrigation to mulberry plant has recorded highest soil physical and chemical properties viz., bulk density (1.39 Mg m-3), water holding capacity (37.83%), soil pH (7.38), electrical conductivity (0.21 dS/m), organic carbon (0.92%), organic matter (1.58%), available N (275.96 kg/ha), available P2O5 (54.76 kg/ha), available K2O (181.41 kg/ha), calcium (3.55 meq/100 g), magnesium (1.75 meq/100 g), sulphur (7.53 ppm), iron (14.40 ppm), manganese (15.28 ppm), zinc (0.71 ppm) and copper (0.91 ppm) compare to control.
