ABSTRACT

Onion is an important vegetable crop in Nigeria grown in both wet and dry seasons

though it fetches higher profit when cultivated in the dry season. The crop yield is

limited by some production constraints, notable of which is the „Danzazzalau‟ disease

in Kebbi State. Fungi isolated from infected pseudostem and roots of onion were

Fusarium sp. and Thielavia sp. Pathogenicity test was conducted using these fungi

and Fusarium sp. proved to be pathogenic on 6-week old onion seedlings. Fusarium

sp. was identified as a Fusarium species belonging to biological group clade V. by

Centre for Agriculture and Bioscience International (CABI), Egham, Surrey, United

Kingdom. Trials were carried out in the screenhouse and field during 2015 dry season

at Samaru, Zaria to study the effects of water regimes, manure rates and mulch

treatments for the management of „Danzazzalau‟ disease of onion crop. The

treatments consisted of three water regimes (3, 10 and 21-day), three manure rates (0

Kg/plot, 40 Kg/plot, and 80 Kg/plot) and three mulch types (polyethylene sheet, rice

straw and no mulch) laid out in a Split Plot Design (SPD) with three replications.

Water regime was the main plot while manure rates and mulch types were the sub-

plots. Incidence and severity of the disease and its effect on onion growth and yield

were determined. Lowest disease incidence (36.02 %) and severity (32.93 %) were

obtained at the 21-day water regime. The 21-day water regime and rice straw mulch at

1.2 mt/ha produced highest bulb yield of 4.67 t/ha and 4.80 t/ha
