- Abstract
The Productivity response of tiger nut (Cyperus esculentus) to size of planting material (tubers) and moisture stress was evaluated in a greenhouse at Federal University of Agriculture, Abeokuta during March- June 2014. The trial was a 3 X 4 factorial experiment arranged in completely randomized design and replicated three times. There were large, medium and small tuber sizes as well as four intervals of irrigation (3, 7, 12 and 17 days) imposed between 4th and 7th week after planting. The results showed that emergence was significantly (p<0.05) affected by tuber size. At 14 days after planting it was 67, 39 and 28 percent for large, medium and small tubers, respectively. Fresh weight of biomass, total number of tubers and total weight of tubers were significantly reduced (p<0.05) as moisture stress increased. The significant interaction between tuber size and number of tubers produced showed the medium sized tubers to be more consistent. It was concluded that large and medium sized tubers gave better emergence; and exposure to moisture stress for 12-17 days led to as high as 41-46 percent reduction in tiger nut productivity.
