Study of different Nitrogen levels on growth parameters of Kharif Onion (Allium cepa L.) under Malwa region

In the present study three onion varieties i.e. Agrifound Red, Bhima Shubra Red and Bhima Sweta were grown under five different levels of nitrogen (i.e. 00, 60, 90, 120 and 150 Kg/ha) The effect of different treatments on different growth parameters [plant height (cm), number of leaves per plant, dry weight of shoot per plant (g), dry weight of bulb per plant (g), leaf area per plant (cm²), and days taken to maturity was studied. It was observed that in general growth parameters show positive response on application of nitrogen although among varieties response is varied.
