Effect of zinc and iron ferti-fertification on growth, yield and economics of baby corn (Zea mays L.)

Abstract

A field experiment was conducted during Kharif, 2017 to study the effect zinc and iron as soil and foliar application on growth, yield and economics of baby corn at IFS Unit, MARS, Raichur, Karanataka. The experiment consisted of ten treatments and laid out in Randomized Complete Block Design with three replications. The results revealed that significantly higher plant height (201.96 cm), leaf area (80.92dm2 plant-1), total dry matter (132.95g plant-1), green cob (14.12 t ha-1) and stover yield (29.42 t ha-1), gross returns (Rs. 241278 ha-1), net returns (Rs.199127 ha-1) and B:C (4.72) with soil application of ZnSO4 @ 25 kg ha-1, foliar application of ZnSO4 @ 0.5 %, soil application of ZnSO4 @ 25 kg ha-1 + foliar application of ZnSO4 @ 0.5 % which shows on par result with soil application of ZnSO4 @ 25 kg ha-1 and FeSO4 @ 10 kg ha-1 and soil application of ZnSO4@ 25 kg ha-1 + foliar application of ZnSO4 @ 0.5%. Application of both zinc and iron as soil and foliar significantly increase growth and yield of baby corn as compared to control.
