Comparative Effects of Conventional Fertilizers and Nymphaea lotus Leaf Extract on Growth, Nutritional Composition and Chlorophyll Contents of Solanum macrocarpon L
The rising demand for food due to increased population and concern over food safety because of synthetic fertilizers and polluted animals manures has led to the use of alternative nutrient sources for crops. Hence, the study aimed at comparing conventional fertilizers and N. lotus extract on growth, nutritional composition and chlorophyll contents of S. macrocarpon. Loam soil, N. lotus and mature seeds of S. macrocarpon were obtained from Lagos State Agricultural input Supply, Ojo respectively. Poultry manure PM-1Kg , NPK-15:15:15 NPK-10g and N. lotus extract LF-10gg dried N. lotus+100ml water were applied on S. macrocarpon. Study was setup-PM, NPK, LF, PM+LF,PM+NPK, PM+NPK+LF, NPK+LF and CTRL control . Morphometric data were collected one week after treatment for 5 weeks, proximate composition and chlorophyll contents were determined across treatments. Descriptive statistics such as mean-standard deviation and one-way analysis of Variance were done using Statistix 10 software. results revealed that the use of combined NPK+LF enhanced stem height, stem girth, leaf length, leaf breadth, and leaf area compared to individual treatment except for number of leaves and number of fruits which favoured PM+LF. PM+LF improved the moisture, crude protein, and crude fibre contents compared to other fertilizer types. Also, PM+LF improved Ca, Na, and K contents compared to other fertilizer types used except N and P which favoured PM+NPK+LF and PM respectively. PM+NPK and PM+NPK+LF had the highest total chlorophyll contents compared to other treatment except Chlorophyll b which was higher in PM+LF. Thus, this study, therefore, concludes that N. lotus extract +poultry manure or NPK+N. lotus extract for better quality and quantity of S. macrocarpon.
