Effect of Zinc Fertilization on Yield of Baby Corn (Zea Mays L.)

A field experiment was conducted on sandy clay loam soil at College farm, College of Agriculture, Rajendranagar, Hyderabad during kharif, 2016 to evaluate the soil and foliar applied zinc response in baby corn. The experiment was laid out in a randomized block design consisting of twelve treatments and replicated thrice. In the present experiment significantly higher growth parameters, yield and yield attributes and quality parameters was recorded with soil application of ZnSO4 @ 25 kg ha-1 + foliar spray of ZnSO4 @ 0.2% at 25 DAS and at 40 DAS over control (no zinc). Increasing level of zinc application had a marked effect on all the growth characters and yields. Likewise cob yield, corn yield, husk yield and green fodder yield were highest with soil application of ZnSO4 @ 25 kg ha-1 + foliar spray of ZnSO4 @ 0.2% at 25 DAS but remained on par with treatments T9: soil application of ZnSO4 @ 25 kg ha-1, T10: soil application of ZnSO4 @ 25 kg ha-1 + Foliar spray of ZnSO4 @ 0.2% at 25 DAS, T11: soil application of ZnSO4 @ 25 kg ha-1 + Foliar spray of ZnSO4 @ 0.2% at 40 DAS whereas no zinc treatment resulted lower yield and yield attribute
