Effect of micronutrients on growth, yield and quality of onion (Allium cepa L) cv Phule Samarth

A field experiment was conducted to evaluate the effect of micronutrients on growth, yield and quality of onion (Allium Cepa L) cv Phule Samarth using six treatment combinations containing soil application and foliar spray of micronutrients along with control under RBD replicated four times, during kharif (rainy) season of 2022-23 at the Oilseeds Research Station, Mahatma Phule Krishi Vidyapeeth, Jalgaon, Maharashtra. Among different treatments, the application of 100 per cent RDF + 20 tonnes FYM + soil application of ZnSO₄ @ 25 kg/ha and 100 per cent RDF + 20 tonnes FYM + foliar spray of mixture of ZnSO₄ @ 0.5 per cent and borax @ 0.25 per cent at 30 and 45 DAT, resulted in higher plant height of 60.66 and 59.33 cm at 60 DAT, number of leaves of 8.73 and 8.50 at 45 DAT, polar diameter of 5.86 and 5.53 cm and yield of 25.55 and 23.98 MT per hectare respectively, as compared to all other treatmentw. However, the treatment 100 per cent RDF + 20 tonnes FYM + soil application of ZnSO₄ @ 25 kg/ha resulted in maximum bulb weight of 111.66 g among all the treatments applied.
