ABSTRACT:

The study was conducted for two years, 2017 and 2018 dry season at the Institute for Agricultural Research (IAR) Farm, Samaru located 686m above sea level in the Northern Guinea Savanna of Nigeria to investigate the poultry manure fertilization on growth and yield of onion varieties to under irrigated conditions. Treatments consisted of four (4) levels of poultry manure (0, 2, 4, 6 t ha-1and a Recommended NPK ), three varieties of onion (Red creole, Galmi Spv, Wuyan- Bijimi). All the treatments were factorial combined and laid out in a randomized complete block design (RCBD)which was replicated 4 times. The result revealed that the use of 6 t ha-1 poultry manure significantly influenced number of leaves, crop growth rate, onion bulb weight and yield. The results indicated that plot treated with NPK significantly had more percent rotted and sprouted bulbs during storage compared to poultry manure plots while the local varieties Wuyan-bijimi and Galmi produced less percent rotted bulbs. However, variety Wuyan-bijimi gave the least percentage on sprouted bulbsthan Red Creole and Galmi which gave more sprouted bulbs that were statistically similar. Based on the result obtained, growing Wuyan-bijimi or Red Creole with application of 6 t ha-1 PM or120:45:45 kg ha-1 NPK are recommended for possible adoption by farmers
