Abstract

---

Root-zone temperature (RZT) changes with season, geographical location and global warming. Nutrient accumulation and use behaviour of two maize (Zea mays L.) genotypes were evaluated under low (22.4 ± 5°C) and high (28.8 ± 5°C) root-zone temperatures. In greenhouse study, hybrid maize (FHY-396) and indigenous variety (EV-7004) were sown in calcareous loam soil filled in pots. Shoot and root dry matter yield of both the genotypes was significantly (p
