Abstract

A field experiment was conducted during the rabi season of 2024–25 under open field conditions in Banaskantha district of Gujarat to study the effect of fermented organic manure (UTPANN FOM) on growth, yield and quality of onion (Allium cepa L.). The experiment was laid out in a Randomized Block Design with two treatments, T1 control no nutrient input and T2 application of UTPANN FOM 10 kg/acre, replicated three times. The treatment receiving application of UTPANN Fermented Organic Manure (FOM) recorded a higher yield of 27.96 t/ha as compared to the control. Plant growth characteristics, such as plant height 56.78 cm, number of leaves per plant 9.21, and neck thickness 11.36 mm, were also improved bulb yield, as shown in higher yield parameters such as bulb diameter 6.18 cm and average bulb weight 102.36 g under UTPANN FOM application. Quality parameters showed higher values of total soluble solids 11.86 °Brix, dry matter content 14.67% and shelf life 68.5 days. The improvement in growth, yield and quality was associated with better nutrient availability, improved soil condition, enhanced microbial activity and balanced nutrient supply under fermented organic manure application.
