Standard procedures were followed in these assessments: Proximate composition (carbohydrate, protein, fibre, lipid, ash and moisture), Mineral elements (magnesium – Mg, calcium – Ca, iron – Fe, potassium – K and sodium – Na), vitamin C and chlorophyll (a and b). The study showed varied proximate composition, mineral elements, vitamin C and chlorophyll contents across the vegetables assessed. For proximate composition, the following ranges were recorded: 2.78 – 8.99%, 9.63 – 14.00%, 5.43 – 12.15%, 0.001 – 0.013%, 1.91 – 3.14% and 63.38 – 78.01% for carbohydrate, protein, fibre, lipid, ash and moisture contents, respectively. Among the vegetables, G. africanum recorded the highest value for carbohydrate, fibre, lipid, Fe, vitamin C and chlorophyll b. However, recorded the least value for moisture, ash, Mg and K contents. Secondly, L. africana had highest value for moisture, Ca, K, and Na contents and least value for protein, fibre, lipid, vitamin C, chlorophyll a and b contents. The K content in L. africana was statistically different at p≤0.05 with other vegetables. The study recommends the consumption of these nutritious vegetables based on dietary requirement of individuals.</em></p> <p><strong> JEL Classification Codes:</strong> O13.</p> Josephine Udunma Agogbua , Kalu Okonwu , Daniel Akaninyene Archibong , Festus Austine Ikpowosa Copyright (c) 2022 Josephine Udunma Agogbua , Kalu Okonwu , Daniel Akaninyene Archibong , Festus Austine Ikpowosa Tue, 07 Jun 2022 00:00:00 +0000 HYDROPONICS PRODUCTION OF CUCUMBER AS SOIL FARMING ALTERNATIVE IN NIGERIA <p><em>The constant farmers-herders clash has predisposed farmers to insecurity in Nigeria thereby making farming in open field difficult. The hydroponics system has gained popularity in the cultivation of vegetable crops around the World. However, in Nigeria, there is dearth of information on hydroponics usage as an alternative to soil farming. Hence, the need to investigate the suitability of producing cucumber in Nigeria using the hydroponics system compared to soil. Seeds of three cucumber varieties were grown in cocopeat substrate and topsoil in a 3 (genotypes) by 2 (substrate) factorial experiment laid in a completely randomized design with 3 replicates. Each plant was fertigated with 100 ml of liquefied poultry manure weekly and was watered every 3 days till harvest. Data were taken on the number of leaves, plant height, leaf area, days to flowering and fruiting, number of fruits and average fruit weight. Data collected were analyzed using ANOVA and differences in the treatment means were separated using least significant differences at 5% level of significance. Result obtained showed significant differences among genotypes in the growth and yield parameters with Poinset having the highest number of fruits (6.88±0.57) and fruit weight (275.00±17.03), while the substrate effect was not significant.</em></p> <p><strong>JEL Classification Codes: </strong>Q15.</p> Chukwunalu Okolie Ossai , Stephanie Clara Akpeji , Ifeakachukwu Sunday Alama , Fidelis Nduka Emuh Copyright (c) 2022 Chukwunalu Okolie Ossai , Stephanie Clara Akpeji , Ifeakachukwu Sunday Alama , Fidelis Nduka Emuh Wed, 15 Jun 2022 00:00:00 +0000 PERFORMANCE OF TELFAIRIA OCCIDENTALIS LEAF GROWN IN UREA HYDROPONIC SOLUTION <p style="text-align: justify;"><em>The study evaluated the performances of Telfairia occidentalis Hooker fil. under varying growth media subject to the amount of Urea granules (25 g, 50 g, 75 g, 100 g, 125 g and 150 g) dissolved in water containing micronutrients. The growth media were M25U, M50U, M75U, M100U, M125U, M150U, and Control. Two-week old seedlings of T. occidentalis raised using River-sand were transferred into the non-circulatory growth media. The growth indices (vine main length (VML), number of leaves (NL), stem girth (SG), petiole length (PL), internode (LI), leaf area (LA), and total leaf area (TLA)) of T. occidentalis were measured weekly. The root length (RL), root fresh weight (RFW), root dry weight (RDW) and pigment components were determined 5 weeks after planting following standard procedures. Across the growth media studied, the Control medium had the highest VML, NL, LA, TLA, PL and pigment composition of T. occidentalis. However, among the Urea growth media, M25U medium produced relatively the highest VML, NL, TLA, total chlorophyll, and RFW of T. occidentalis while M50U medium had the highest LA, RL and RDW. Also, T. occidentalis leaves grown in the Control medium had the highest chlorophyll content (33.22 mg/g), followed by M25U medium (22.88 mg/g) and was significantly different from the other growth media.M100U medium effectively enhanced carotenoids content (6.49 mg/g) of T. occidentalis compared to others. The study showed that the mineral composition of the growth media enhanced the performance of T. occidentalis. Hence, M25U growth media are recommended for growing T. occidentalis.</em></p> <p style="text-align: justify;"><strong>JEL Classification Codes: </strong>O13.</p> Love Akaja Akonye , Kalu Okonwu , Josephine Udunma Agogbua Copyright (c) 2022 Love Akaja Akonye , Kalu Okonwu , Josephine Udunma Agogbua Sat, 03 Sep 2022 00:00:00 +0000
