Abstract

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