dc.description.abstractOnion is one of the most important vegetable crops grown in Uganda, because of its nutritional and economic value. However, production of onion in Uganda is very low due to nutritional imbalances in the soil. Therefore, soil fertility remains one of the key areas of focus in sustaining onion production. A field experiment was conducted to assess the response of onion variety Red Creole C-5 to different soil organic amendments at Kyambogo University during the period February 2016 and January 2017. The experiment was laid out in a randomized complete block design with four replications. The treatments included T0: without manure (control), T1: green manure (GM), T2: farmyard manure (FYM) and T3: compost manure (CM). Data collected included: plant height, root length, plant fresh and dry weight, number of leaves per plant, fresh and dry weight of bulbs, diameter of bulbs and commercial yield computed. Data were analysed using Genstat. There was significant response of onion to the different soil organic amendments. Onion plant height, number of leaves, root length, dry and fresh weight and bulb weight were high in farmyard manure, followed by compost manure and lastly green manure, compared to the control. The highest yield (12,000 kg/ha) was obtained from the plots amended with farmyard manure as opposed to the control. It was therefore concluded that farmyard manures had a greater effect on the agronomic and yield performance of onion. Future study with more than one onion genotype is recommended so as to widen the scope of this result.en_US
