Abstract
Aim: Evaluation of raw and treated sewage water irrigation on yield and quality of V1 mulberry.
Study design: The Experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications and six treatments comprises of different proportions of raw sewage water, treated sewage water and borewell water.
Place and duration of study: The study was conducted during Rabi 2019 in pre-established irrigated V1 mulberry garden at Department of Sericulture, University of Agricultural Sciences, GKVK, Bengaluru, Karnataka, India.
Results: Data recorded on quality parameters of mulberry revealed that raw sewage water irrigation significantly increased the leaf nutrient content such as N (3.68%), P (0.4%), K(1.91%), S (0.34%), Zn (30.08 ppm), Mn (103.75 ppm), Fe (373.75 ppm) and also leaf yield (804.31 g/plant) is significantly increased in 100% raw sewage water irrigation, whereas higher leaf Ca (2.06%) and Mg (0.71%) content was recorded in 100% borewell water irrigated plot, and the lowest leaf N (2.82%), P (0.28%), K (1.33%), S (0.17%), Zn (18.03 ppm), Mn (75.75 ppm), and Fe (336.5 ppm) content was found lower in 100% borewell water irrigation.
Keywords: Mulberry leaf quality, leaf yield, raw sewage water, treated sewage water
