Impact of sensor-based wastewater irrigation on chemical soil health in chrysanthemum (Chrysanthemum morifolium)

A field experiment was conducted to study the short-term impact of sensor-based wastewater irrigation scheduling on chemical soil health in chrysanthemum (Chrysanthemum morifolium Ramat.) at Water Technology Centre, ICAR-Indian Agricultural Research Institute (IARI), New Delhi during 2019–20. Experiment with following 6 treatments, viz. T1, Groundwater (GWI) 25% Maximum Allowable Depletion (MAD), T2, GWI 50% MAD, T3, 75% T4, Wastewater (WWI) T5, WWI T6, MAD and laid out a randomized block design (RBD) open condition 4 replications. Soil samples quality groundwater were assessed after quantify properties (pH, EC OC), primary nutrients (NPK), micronutrients (Fe, Mn, Cu Zn) heavy metals (Ni, Pb, Cr Cd). Results shows that pH remains same. Organic carbon, nutrient content significantly increased irrigated soils best result observed T5. Moreover, Cr, Cd Pb) not changed different treatments. have beneficial impacts parameters terms higher amount organic matter, soil.
