Effect of chelated zinc and iron on the uptake and quality parameters of summer groundnut (Arachis hypogaea L.)

Abstract

The field experiment entitled Effect of Chelated zinc and iron on Summer Groundnut of uptake and quality parameters was undertaken during the summer 2022-23 at Oilseed Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The experiment was laid out in Factorial Randomized Block Design (FRBD) with two factors (Soil application and Foliar spray of chelated micronutrients (Zn EDTA and Fe EDDHA) replicated three times. The results of the present investigation revealed that, the uptake of N, P, K, Zn, Fe, Cu and Mn of summer groundnut was significantly highest with Soil application of chelated zinc and iron S3 (100% RDF + Zn EDTA @ 1.5 kg ha-1 + Fe EDDHA @ 1.5 kg ha-1) along with foliar spray of chelated zinc and iron F3 (Zn EDTA @ 0.5% + Fe EDDHA @ 1.0% at 35 and 65 DAS). The highest protein and oil content is in Soil application of chelated zinc and iron S3 (100% RDF + Zn EDTA @ 1.5 kg ha-1 + Fe EDDHA @ 1.5 kg ha-1) along with foliar spray of chelated iron and zinc F3 (Zn EDTA @ 0.5% + Fe EDDHA @ 1.0% at 35 and 65 DAS) and this was non -significant among the treatments.
