Juice extracted from sugarcane can be used extensively in manufacturing brown sugar, industrial sugar and bioethanol fuel through the process of fermentation; hence, the need to develop a machine that can extract juice from sugarcane effectively. This work involves the design, fabrication and performance evaluation of sugarcane juice extractor. The machine was designed to extract juice from sugarcane at small scale level suitable for small and medium scale sugarcane processors. The prototype machine was designed, fabricated and assembled in the Department of Agricultural and Bio-resources Engineering, Ahmadu Bello University, Zaria. The machine consists of rollers, gears, cane guide, juice collector, frame, and prime mover. The developed machine was evaluated using <em>koma</em> variety of cane and obtained an output capacity of 148.2 kg/h and extraction efficiency of 67.44%, respectively at a speed of 30 rpm. The production cost stood at N 90,000 which is affordable and therefore recommended for small scale processors.</p> N. Oji M. A. Gwarzo U. S. Mohammed I. Abubakar J. K. Agunsoye A. Zakariyah E. I.

The study made use of ASTER data of 2017 with spatial resolution of 30m, topographical map at a scale of 1:50,000, monthly rainfall data for 35 covering the study area and soil map at a scale of 1:50,000. Thematic maps for soil, rainfall and elevation were produced converted to raster data in GIS environment. Each data set in a single map was given weight by pair-wise comparison; reclassification of each map was done based on the weights generated from the pair-wise comparison of each dataset. The results showed that the rainfall recorded in the study area ranges from 950mm to 1150mm and this is categorized between high and very high under the pair-wise comparison rating. The elevation is such that parts of the study area had high elevation that ranges between 226m and 255m and low elevation that ranged between 125m and 167m giving room to flooding. The soil types in the study area are such that encourage flooding coupled with high amount of rainfall on one hand and the high and low elevations experience across the study area. For the farmers to sustain agricultural activities as a result of flooding, they practiced mixed farming, shifting cultivation, terrace farming, fallow and arable farming. The above farming systems were practiced by the farmers to alternate, avoid or take advantage of the floods. In conclusion, the study recommends the use of more resistant seedlings and crops to flooding, channelization of the river should be carried out by the government to reduce the level of flooding across the study area among others.</p> Daniel Habila Galadima Ishaya K.

The major staple grains are the most important field crops and the chief element in the diet of most Ethiopians. Maize is the largest and most productive crop in Ethiopia. In 2007/08, maize production was 4.2 million tons, 40 percent higher than teff, 56 percent higher than sorghum, and 75 percent higher than wheat production. Postharvest losses are major problem in enhancement of maize production. The main controlling mechanism to avoid these losses is using appropriate grain storage. As FAO introduced&nbsp; stated household metal silo is a key post-harvest technology in the fight against hunger and for food security. The house hold air tight metal silos generally hold between 100 and 3 000 kilos. The objective of this activity is to minimize post-harvest losses of maize grains by introducing this airtight silos in selected wordea’s of the region.</p> <p>Different air tight silos were manufactured according the SDC Manual for Manufacturing Metal Silos for Grain Storage in MAMRERC workshop. Preliminary test was conducted to check air leakage and strength of welding of the silo. Farmers were selected based on the willingness and resource they have. Weight loss, relative humidity, temperature, moisture content, count breakage from 1000kernel and insects occurred and farmer’s perception was collected in compiring with tradition silo and plastic bag.</p> <p>From these the air tight silo has low weight loss form 125gm initially and after recorded for six months the weight reduces to 122.6, 114.35, and 112.25gms respectivly.&nbsp; The moisture of maize grain decrease&nbsp; from 13% have different in the three containers 26.48, 28.72 and 27 and difference of&nbsp; -0.52, 1.72, and 0 and average Relative humidity's are 7.96, 4.96, and 3.96 for metal silo, traditional Gottera and plastic bag respectively.&nbsp; The counted and damaged from 1000 kernels are high in plastic bag and traditional silo. the farmers perception in relative advantage and characteristic of the silo are good.</p> Dawit Hadera ##submission.copyrightStatement## 2019-11-02 2019-11-02 1 10 10.9734/arja/2019/v11i430066 Combnining Ability of Sweetpotato Yield in Endemic and Non-endemic Sweetpotato Weevil (Cylas formicarius) Environments in South West Nigeria <p><strong>Introduction: </strong>Combining ability studies in sweetpotato marketable root yield were carried out using ten sweetpotato varieties and their F<sub>1</sub> hybrids in <em>Cylas formicarius</em> endemic (Omu Aran) and free (Ibadan) environments during 2012 cropping season.</p> <p><strong>Study Design:</strong> The genetic material used for this experiment was from the germplasm &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;collection of the Department of Agronomy, University of Ibadan, Nigeria. This material &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;comprised of 10 varieties of sweetpotato: 5 orange fleshed, 3 white fleshed and 2 yellow &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;fleshed.</p> <p><strong>Place and Duration of Study: </strong>The field trial was carried out in <em>C. formicarius </em>endemic (Omu Aran) and Non-endemic (Ibadan) environments both in South West Nigeria during the raining season of 2012.</p> <p><strong>Methods: </strong>Collected data were subjected to diallel analysis using Griffing (15) approach in method I (parents, crosses reciprocals together), Model I (fixed effects). Both general combining ability (GCA) and specific combining abilities (SCA) were computed using PBTools, version 1.4. for the 10 parents and their F<sub>1</sub> hybrids with respect to <em>C. formicarius.</em></p> <p><strong>Results and Discussion: </strong>The result obtained from this study showed that some parents were tolerant to <em>C. formicarius</em>, but level of tolerance varied probably due to differences in genetic background among the parental population or time of planting. Hybrids from the parents resisto, TIS 87/0087 displayed high performance in term of <em>C. formicarius </em>tolerance. These parents and their hybrids appeared to have gene pools for <em>C</em>.<em> formicarius</em> tolerance that can be manipulated and used to develop promising hybrids in South west, Nigeria. <strong>&nbsp;</strong></p> M.
