Onion (Allium cepa L.) Bulb Crop Production Using Sets of Two Sudanese Cultivars

The objective of this research was to determine production requirement for onion bulb crop using sets as, rarely but high potential, planting material. An experiment carried out at the Demonstration Farm Faculty Agriculture, University Khartoum two consecutive growing seasons,(2010/11 and 2011/12). Treatments comprised cultivars(Saggai Kamlin), three set sizes (small 1-1.5 cm diameter; medium 1.6- 2.1 large 2.2-2.7 cm) dates (15th August, September October). were arranged in a split plot design with replications, where cultivars randomized main plots, sub-plots sub-sub plots. Resultsindicated that increasing size from small significantly promoted plant growth. Medium resulted higher average weight, total marketable yields than sets; however, splitting premature bolting (negative quality traits) also high. So yield represented range 40-46 %, 39-49 % and25-53 over years when medium, used respectively. Plant growth, diameter, planted inOctober August; yet, higher. Early August increased dry matter. Saggai cultivar had tendency Kamlin as Total October August. It is concluded use material good transplants, if not better, it more easy adaptable continuously changing environment terms climate change cost.
