Abstract

During the 2013 and 2014 harvest seasons, field and laboratory experiments were conducted in Nigeria’s inferred agroecological zone. The nutritive value of fluted pumpkin ( Telfairia occidentalis ) leaves was evaluated by measuring the levels of carbohydrate, protein, fat, ash, dietary fiber, and moisture content in Telfairia occidentalis using the standard analytical methods. The experiment was laid out in a randomized complete block design (RCBD) and repeated four times. Three separate applications of paraquat herbicide (non-selective) at rates of 100, 150, and 200 L ha −1 were applied to the treated plots. Comparative studies of the nutritive value of T. occidentalis were observed in the treatment and control plots. The effects of herbicides showed that the proximate composition of the T. occidentalis leaves of the treated plot was 70% carbohydrate, 29% protein, 1.8% fat, 1.7% dietary fiber, 7.9% ash, and 8.7% moisture. In contrast, the values of the control plots were 6.5% carbohydrate, 1.9% protein, 1.5% fat, 1.2% dietary fiber, 7.0% ash, and 7.9% moisture. The results show that paraquat herbicide spray increased moisture, protein, fat, carbohydrate, ash, and vegetable yields in the treated plot and that T. occidentalis leaves are rich in lipids, fiber, and protein. As a result, the control plot’s fiber, carbohydrate, protein, ash, and moisture content decreased drastically without using paraquat. These results demonstrate that herbicides can affect the nutritional yield of T. occidentalis by eliminating weeds alongside the main crops ( T. occidentalis) in the agroecological zone of south-eastern Nigeria. Therefore, if consumed in sufficient quantities, the studied leafy vegetables will significantly contribute to the nutritional needs of human health and the Nigerian population’s food security.
