Overview

Randomized block design shows phosphorus and zinc improve safflower yield in calcareous soil, indicating nutrient interactions are vital.

Key Points

  • Safflower yields improved significantly with 200 kg P2O5 ha-1 and 30 kg Zn ha-1, showing high seed yield of 13.450 Mg ha-1.
  • Analysis revealed oil content of safflower seeds reached 42.660%, influenced by phosphorus and zinc interactions.
  • Using randomized complete block design with three replicates, factors included different levels of phosphorus and zinc application.
  • Findings highlight the significance of nutrient interactions for optimizing safflower growth in calcareous soils.
