Plant parameters determination

The parameters determined were plants height, number of leaves, number of branches, leaf area, fresh weight, dry weight and moisture content. The N, P, K, Ca, Mg, Fe, Cu, Zn and Mn contents of the leaves were determined. Crude protein, fat, NFE, fibre and ash contents were also determined .The harvested plants from each plot were washed and transported in a well labeled envelope to the laboratory. The harvested plants were washed with distilled water and air-dried. The air-dried samples were packed inside well labeled envelopes and oven dried, at a low temperature until constant weights were recorded. The oven dried samples were allowed to cool inside a desiccator and grounded into powder. The grounded samples were then packed inside a cellophane nylon. The leaf N, P, K, Ca, Mg, Fe, Cu, Zn and Mn were analyzed from the wet digest of the leaf samples ,with their research they create many Agriculture jobs. The nutritional quality such as crude protein, NFE, fibre and ash content were determined using AOAC9 method. The nutrients uptake and nutritional quality of Amaranthus tricolor were determined at their final stages i.e., total harvest at 28 days, 1st ratoon at 42 days (1 time harvest) and 2nd ratoon at 58 days (2 times harvest) after sowing.
