A split plot design was adopted for the study with two maize varieties assigned to the main plots and nitrogen with cow dung assigned to the subplots in a factorial combination. Nitrogen rates of 0, 60 and 120 kg N ha<sup>-1</sup> and cow dung 0, 1 and 2 ton ha<sup>-1 </sup>were used. Data were collected on number of cobs per plant, cob length, 100 grain weight and grain yield per hectare. Data collected were subjected to analysis of variance using SAS system for windows 9.2 version 2005 and treatment means were separated using Duncan Multiple Range Test. Result showed that the effect of nitrogen fertilizer on the yield and yield parameters increased significantly with the use of 120 kg N per ha<sup>-1</sup> recording the highest for cob length (17.68 cm) 100 grain weighs (32.89 g) and grain yield (5658.3 kg). The control plot produced the least. Application of 2 ton ha<sup>-1</sup> cow dung exhibited the highest yield. there was an interaction of variety with nitrogen on cob length and grain yield. Application of 120 kg N ha<sup>-1</sup> significantly increased the yield of Quality Protein Maize (QPM) along with 2 ton ha<sup>-1</sup> cow dung.</p> Iliyasu Audu ##submission.copyrightStatement## Thu, 12 Mar 2020 00:00:00 +0000 Production Mapping and Description of the Organoleptic Qualities of Local Varieties of Plantain (Musa spp. AAB) Cultivated in Côte d’Ivoire <p><strong>Aims:</strong> A field survey was carried to apprehend the full diversity of Ivorian’s plantain. The aim was to produce a reliable and up-to-date production map of the local varieties. This study was also intended to determine their level of appreciation by local consumers on the basis of their physical, technological and sensory characteristics.</p> <p><strong>Place and Duration of Study:</strong> The enquiries data were collected in 87 villages distributed into 22 regions of Côte d'Ivoire, between September and December 2017.</p> <p><strong>Methodology:</strong> During the survey, data on the production, description, processing and consumption of local plantains were collected by direct individual interviews using a structured questionnaire. This information was collected in a participatory manner from 1232 (14 producers/villages).</p> <p><strong>Results:</strong> This study identified twenty-two (22) varieties of plantain, traditionally cultivated for several generations in Côte d'Ivoire. The greatest varietal diversity has been observed in the South-East and the East, notably in the regions of Sud-Comoé, Indénié-Djuablin, Mé and &nbsp;&nbsp;&nbsp;Agneby-Tiassa. These varieties are variously appreciated according to their physical and organoleptic characteristics. People used them to make the usual plantain-based dishes found in Côte d’Ivoire. However, for the most questioned people, cooking specific plantain dishes requires the using of specific varieties with particular characteristics. The <em>Agnrin</em>, <em>Molegna</em>, <em>N'gretia</em>, <em>Molekotoba</em>, <em>Ameletia</em>, Purple banana and <em>Banadiè</em> varieties have been designated to be the best for “<em>foutou”</em>. In addition, the <em>Banadiè</em> variety, even in the green state, gives a nice yellow “<em>foutou</em>”. The above varieties are said to be perfect to prepare “<em>Aloco”</em>, “<em>Docklounou”</em> and “<em>Clacro”</em> at advanced ripening stages. The <em>Afoto,</em> Spotted banana, <em>Kpatrè-kou</em>, <em>Kpatragnon</em>, <em>Kpatrè-n'san</em> varieties, were recommended for “<em>foutou”</em>, “<em>foufou”</em>, roasted or chips because of their volume.</p> <p><strong>Conclusion:</strong> Further researches are underway to explain, scientifically, the sensory and technological differences usually observed between local plantains varieties.</p> H.

In this study the important roles of area enclosure with comparison to an open sites were investigated for physicochemical properties of soil in rangeland of Shilabo district Somali region, east Ethiopia. The management types (5 yrs enclosures, 10 yrs enclosure and open grazing land) were taken as treatments. The sand, silt and clay content of CGL, 5E and 10E were 78, 76 and 75%; 8.67, 12.00 and 14.67% and 14.67, 10.33 and 10.33% respectively. Where the mean value of N, P and K for CGL, 5E and 10E were 0.04, 0.14 and 0.16%; 3.72, 3.91 and 5.96 mg/L and 0.16, 1.05 and 1.53 (cmol (+)/Kg soil respectively. The soil variable results revealed that soil organic matter, CECs, exchangeable Cat ions and soil moisture were significantly improved as a result of the enclosure. This study generally shows that area enclosure is a promising strategy to rehabilitate degraded environments as it is fast, cheap and lenient.</p> Mowlid Hassan, Zawde Tadesse, Mohamed Abdikader, Dinow Sharif ##submission.copyrightStatement## Fri, 27 Mar 2020 00:00:00 +0000
