Site selection, soil analysis, and climatic conditions
.7053030 N
The present study was carried out at four sites i.e. farmer’s field in Multan (29°.959593 N, 71°.343759 E), Faisalabad (31°.7053030 N, 73°.0215580 E), Sahiwal (30°.533018 N, 72°.758652 E) and Lahore (31°.748680 N, 74°.103364 E) regions. Two-year experiments were conducted on rice (2019 and 2020) and wheat (2019–20 and 2020–21) separately at each site. Pre-sowing soil samples (0–15, 15–30 cm) were analyzed for pH, electrical conductivity (EC), phosphorus (P), potassium (K), zinc (Zn), boron (B), and texture. The pH, EC, B, and texture were measured by following the methods described by [
