However, it is a less utilized perishable crop. Therefore, in other to improve it utilization in processing and bakery products the incorporation with other flours should be considered. In order to use OFSP tubers, incorporation with other flours in processing and baked products can be considered.</p> <p><strong>Study Design:</strong> The physicochemical analysis was carried out at the biochemistry laboratory of National Root Crop Research Institute (NRCR1) while part of the analysis was done at International Institute of Tropical Agriculture Ibadan (IITA). Study lasted for 6 months.</p> <p><strong>Methodology:</strong> Orange-fleshed sweet potatoes (OFSP), yellow roots cassava (YRC) were all sourced from National Root Crops Research Institute Umudike, while the plantain and <em>Moringa oleifera</em> leaves were gotten from Umuahia market and Michael Okpara University of Agriculture Umudike (NRCRI) respectively. The samples were processed into flour and used to form a blend.&nbsp; The flour blend constitute of yellow root cassava, orange fleshed sweet potato and plantain which were fortified with <em>Moringa oleifera</em> leaves at constant portion of 5% while the YRC, OFSP and plantain were varied at different concentration of 65%, 70, 75, 80, 85, 95 and 5, 10, 95 and 5, 10, 15, 25 and 95% I.e. Sample A, B, C, D, E, F, G, H respectively.</p> <p><strong>Results:</strong> The result obtained indicated&nbsp; among the mineral&nbsp; content determined that sample G which serves as the control with 95% Plantain and 5% <em>Moringa oleifera</em> leaves powder exhibited highest in calcium&nbsp; having 13.26 mg/100 g, magnesium 88.06 mg/100 g, potassium 287.70 mg/100 g and iron 2.69 mg/100 g as compared to other composite flour. The phytochemical content of sample F (95% YRC with 5% <em>Moringa oleifera</em> leaves powder) has the highest in alkaloid, tannin and hemagglutinin content as 4.22 mg/100 g 2.26 mg/100 g and 12.43 mg/100 g respectively. The result also indicated that increase in the YRC and decrease in the OFSP caused an appreciable increase in the Vitamin B1, B3 C and D content.</p> <p><strong>Conclusion:</strong> The vitamins, mineral and phytochemical content of the products were enhanced and can be of nutritional benefit to the public.</p> L.

The ingredients used in this study were fresh semen from Boer Goat, tris yolk extender, streptomycin, and sweet orange essential oil. Tris yolk extender is made using Tris (hydroxymethylaminomethane) (3.32 g), citric acid (1.86 g), fructose (1.37 g), glycerol (6 ml), egg yolk (20 ml), aquabides (100 ml). The study design was a non factorial completely treatments given were the addition of sweet orange essential oil at 0%, 0.25%, 0.5%, 0.75% and 1%. The results showed that the addition of a combination of streptomycin and sweet orange essential oil into the tris yolk extender had a highly significant effect (P &lt;0.01) on the percentage value of spermatozoa abnormalities of Boer Goats before and after freezing. The best average value of spermatozoa abnormalities is the addition of sweet orange essential oil at 1% (P4) with the percentage of spermatozoa abnormalities before freezing at 3% and after freezing at 6%.</p> Sukma Aditya Sitepu ##submission.copyrightStatement## 2020-02-11 2020-02-11 20 23 10.9734/ajaar/2020/v12i230076 Soil Physicochemical Properties Variation in Black Soil after the Long-term Application of Different Organic Amendments <p><strong>Aims: </strong>This research aimed to assess how the physicochemical properties of black soil respond to different organic amendments after 10 years of application.</p> <p><strong>Study Design:</strong> The experiment was established in 2010 and followed a randomized block design consisting of 24 plots (5 m × 5 m) 25 m<sup>2</sup> with eight treatments in three replicates.</p> <p><strong>Place and Duration of Study:</strong> The study site was located at the Jilin Agricultural University Research Farm, Northeast China (43°48′ N, 125°23′ E; km).</p> <p><strong>Methodology:</strong> The treatments for the study included an annual input of chemical fertilizer and organic amendments at the surface of the soil. The treatments were: Control (CK), chicken manure (JM), fodder grass (FG), mushroom (MS), maize straw (MZ), tree leaf (TL), pig manure (PM) and cow manure (CM). Chemical fertilizers were added at the rate of 165 kg of N, 82.5 kg of P and 82.5 kg of K ha_1 per year. Application rates of organic materials were adjusted to similar amounts of organic matter (2000 kgha−1). In June 2019, soil samples were collected from each of the amended fields. In each field, three sampling points were randomly selected. Soil samples were collected from the 0 – 20 cm depth using a core sampler then taken to the laboratory for soil physicochemical properties analysis.</p> <p><strong>Results:</strong> Comparing the results of the organic treatments with CK, bulk density decreased by 5.6-18.0% while porosity, EC, pH, total N and SOC significantly increased in the organic treatments by 6.0-25.9%, 8.3-25.0%, 0.52-1.7%, 2.7-54.7% and 1.3-18.4% respectively. The textural class of soil under the different treatments did not change however, the distribution of soil particle size varied among the treatments, where high clay and silt content were recorded in the amended fields. Moreover, the application of different organic materials significantly affected the soil aggregate stability and this was attributed to the increase in organic matter content which accelerated important microbial activities in the soil to improve aggregation. At higher suction potentials, higher water contents were recorded in the organic amended fields mainly due to the improved physical properties of the soil.</p> <p><strong>Conclusion:</strong> The study results showed that the application of organic amendments greatly improves the physical and chemical properties of black soil. Therefore, using these organic amendments can serve as an effective strategy to enhance soil quality and fertility.</p> Yaa Opoku-Kwanowaa Jinggui Wu Xiaodong Chen Ahmed Sharaf Sonny Gad Attipoe ##submission.copyrightStatement## 2020-02-13 2020-02-13 24 34 10.9734/ajaar/2020/v12i230079 Nutritional Qualities of Ginger Mutant Lines Grown in the Humid Tropical Agroecology of Nigeria <p>The present study was aimed to determine the variations in nutritional qualities of 15 mutant lines and two landraces of ginger (<em>Zingiber officinale</em>). Fifteen (15) gamma (γ)-ray induced mutants lines and two landraces of ginger were planted in 2017 early cropping season in the Teaching and Research Farm, Department of Crop Science, Faculty of Agriculture, Forestry and Wildlife Resources Management, University of Calabar, Calabar, Nigeria. To evaluate the nutritional qualities of these seventeen ginger genotypes at maturity, proximate analysis was carried out in the Biochemistry Laboratory of the National Root Crop Research Institute Umudike, Abia State, Nigeria. Using standard and official protocols of the Association of Official Analytical Chemists (AOAC). Results showed that the ginger lines varied significantly (<em>P</em> &lt; 0.01) in all their proximate attributes. The moisture content ranged from 10.13% (UG1) to 12.95% (UG2). Mean dry matter was 88.89%; UG1 and UG2 had the highest (89.89%) and lowest (87.05%) dry matter content, respectively. Mean crude protein was 7.74%; UG2-9-01 and UG2-11-03 had the highest (8.25%) and lowest (7.29%) crude protein respectively. UG1-5-38 and UG1-5-22 had the highest (8.12%) and lowest (6.41%) crude fibre content respectively. The oleoresin content ranged from (6.25%) in UG2-9-01 to (9.09%) in UG1-11-07. UG1-5-04 and UG1-5-22 had the highest (2.88%) and lowest (2.22%) ash content respectively. UG2-9-01 had the highest carbohydrate content of (65.10%). While UG1-5-52 had the lowest (61.27%) The result showed that the ginger lines used in this study had high mean carbohydrate (62.85%) and protein (7.74%) contents as such can be used as supplementary sources of these nutrients for human and livestock. UG1-7-24, UG1-11-07 and UG1-5-18 with high oleoresin contents of 9.11%, 9.09% and 9.05% respectively are recommended to ginger breeders as useful genotypes for improving other ginger lines through micropropagation techniques especially when breeding for oleoresin quality, which is an important quality of ginger. In conclusion, further evaluation and testing of these ginger lines is recommended.</p> M. N. Abua M. A. Ittah E. E. Obok G. A. Iwo R. E. Edugbo C. O.
