Towards Understanding Nutrient Transport in Celosia argentea L. | Chapter 11 | New Perspectives in International Plant and Soil Research Vol. 1
To better understand nutrient transport in vegetable, a pot experiment was carried out at the nursery site of the Department of Crop Production, Federal University of Technology, Minna (9°36’ N, 6°33’ E) Niger state, Nigeria. The study aimed at determining the effect of age of celosia plant at harvest on the yield and nutritional composition of the plant as well as the concentration of nutrients at different leaf positions. The experiment was a 3 x 3 factorial combination of three harvest periods (5, 7 and 9 weeks after sowing) and three leaf positions on the mother plant (upper, middle and basal) arranged in a completely randomized design. Harvested leaves were analysed for the nutritional composition. The results showed that the whole plant fresh weight, varied significantly (p<0.05) with the age of plant at harvest, having the maximum and the minimum values at 9 weeks after sowing (266.19 g/pot) and 5 weeks after sowing (96.12 g/pot) respectively. The leaf fresh weight and lea...
