Response of Iron and Boron on Uptake of Nutrients and Soil Nutrient Status after Harvest of Safflower Crop (Carthamus tinctorius L.) in Kalyan Karnataka, India

Micronutrients are required by the plants in small quantities, but they very important for plant to compete life cycle with this present experiment was conducted at Agricultural Research Station, Hagari, Ballari, Karnataka evaluate response of iron and boron on uptake nutrients soil nutrient status after harvest safflower during two consecutive years 2020-21. The consisted seven treatments, includes T1: Absolute control, T2: RDF (40:40:12.5 kg NPK +30 Sulphur +15 ZnSO4 ha-1), T3: + 15 FeSO4ha-1, T4: 1.0 Boron ha-1, T5: FeSO4 ha-1+ T6: 20 T7: 1.5 ha-1 T8: +1.5 which replicated thrice randomized complete block design. results revealed that combined application i.e. 100% recommended dose fertilizer (RDF) along per ha (T8) recorded significantly higher N. P. K. Fe B crop. availability N, K were control P, T8:RDF ha-1+1.5 treatments.
