Maturity Effects on the Nutritional Composition of Cleome gynandra L. (A Wild Vegetable)

다국어 초록 (Multilingual Abstract)

Cleome gynandra L. is cultivated for its nutritional benefits. Nutritional composition of most vegetable plant increases with relative growth rate. Therefore, the contribution of organic (e.g. goat manure) and inorganic fertilizers (such as NPK) to optimum nutritional composition and productivity of Cleome gynandra is poorly understood. The nutritional benefit at different growth stages is required to optimize its utilization as a vegetable. Therefore, the relationship between relative growth rate and proximate analysis of C. gynandra was investigated. Three treatments (control, 100 kg N/ha and 8 t goat manure/ha) were arranged in a randomized complete block design in field and glasshouse trials. 100 kg N/ha of inorganic fertilizer influenced more proximate constituents such as vitamin C, protein and ash while 8 t of organic fertilizer increased the crude lipid and phytate contents. The field trial was more favourably compared to the glasshouse. The ash content ranged between 6.49-19.64%, fibre 9.62-26.13%, lipid 1.07-6.94%, vitamin C ranged between 68.33-279.7 mg/100 g, protein 36.55-53.82; phytate 0.74-2.91 mg/100 g; oxalate 1.33-2.63 mg/100 g. It further reveals the concentrations of protein, vitamin C, and fibre can be explored better in the 2nd, 6th and 8th weeks respectively. The overall analysis of the proximate parameters analysed on the field and in the glasshouse showed variations in the nutritional composition of Cleome gynandra.
