A field experiment was conducted to study “Growth, yield and economics of pigeonpea as influenced by biofortification of zinc and iron” during kharif 2017 at Agriculture Research Station, Kalaburgi on black clay soil. The experiment was laid out in randomized complete block design with ten treatments and three replications comprising of both soil and foliar application of zinc and iron. Among the treatments, RDF + soil application of ZnSO4 @ 15 kg ha-1 followed by foliar application 0.5% Zn EDTA recorded significantly higher growth attributes viz. plant height (252.5cm), number of primary branches (23.42), secondary branches (25.42), leaf area (17.08), leaf area index (0.95), total dry matter accumulation (210.79 g) at harvest and yield attributes viz. number of pods per plant (169.67), seed yield per plant (51.41 g), pod yield per plant (86.27g) and 100 seed weight (12.05g), as compared to rest of the treatments. Among the different biofortification treatments, significantly higher grain yield (1897 kg ha-1), stalk yield (4760 kg ha-1), husk yield (1654 kg ha-1), net returns (Rs. 86933 ha-1) and B: C ratio (3.89) was obtained in RDF+ soil application of ZnSO4 @ 15 kg ha-1 followed by foliar application of 0.5% Zn EDTA. Significantly lower growth, yield attributes and economics were recorded with recommended dose of NPK only.
