Data were collected from 80 respondents randomly selected from Du, Bukuru, Vwang and Kuru districts. It was collected using structured questionnaire and analyzed using descriptive statistics, farm budgeting and multiple regression analysis. The result revealed that 32.5% of the respondents were between 32 – 36 years of age with a mean of 36.6 years. In addition, the results indicated that 65% of the respondent were male and 71.3% were married with the mean family sie of 7.8 persons. The average year of experience in Irish potato production was 14.8 years. The result also revealed that 80% of the respondent sourced their capital from personal savings. The average farm size was 1.63 hectares. The total costs and returns were N 54,145.94 and N 131,513.75 per hectare respectively. The net farm income and return per naira invested were N77,367.81 and N1.43 per hectare respectively. The operating, fixed and gross ratio were 0.40, 0.01 and 0.41 respectively. The result of the regression analysis on socio-economic factors influencing gross income the cobb douglas production function was chosen as the lead equation with R2 0.819 and F- value of 29.9 which was significant at P < 0.001. The cost of labour had positive coefficient was significant at P < 0.01, cost of fertilizer (P <0.01). Regression analysis on production factors influencing Irish potato production output using linear functional form indicated that R2 was 0.722 and F- value of 31.56 which was significant at (P<0.001). fertilizer was significant at P < 0.001, farm size was significant (P < 0.001). However poor storage facilities, instability in market price and inadequate input among others were the major problem associated with Irish potato production in the study area. The study recommended that formation of cooperatives society or farmers groups to handle marketing problems.

ECONOMIC ANALYSIS OF IRISH POTATO PRODUCTION IN JOS SOUTH LOCAL GOVERNEMENT OF PLATEAU STATE By DIRISU, Precious Asekome ABSTRACT This study examined economic of Irish potato production in Jos South Local Government area of Plateau State. A purposive sampling technique was employed in selecting four districts and eight villages in the study area. Data were collected using structured questionnaire from 80 respondents randomly selected from villages. The data were analyzed using descriptive statistics, farm budgeting and multiple regression analysis. The result revealed that 32.5% of the respondents were between 32 – 36 years of age with a mean of 36.6 years. The results indicated that 65% of the respondent were male and 71.3% were married with the mean family size of 8 persons. The average year of experience in Irish potato production was 14.8 years. The result also revealed that 80% of the respondent sourced their capital from personal savings. The average farm size was 1.63 hectares. The total costs and returns were N 54,145.94 and N 131,513.75 per hectare respectively. The net farm income and return per naira invested were N77,367.81 and N1.43 per hectare respectively. The operating, fixed and gross ratio were 0.40, 0.01 and 0.41 respectively. The result of the regression analysis on socio-economic factors influencing gross income revealed the cost of labour had negative coefficient and was significant at P < 0.01,cost of fertilizer was positive and at (P <0.01). The R2 0.819 and F- value of 29.9 were significant at P < 0.001. Regression analysis on production factors influencing Irish potato production output revealed that fertilizer was positive and significant at P < 0.001, farm size was positively significant (P < 0.001) the R2 was 0.722 and F- value of 31.56 which were significant at (P<0.001). However poor storage facilities, instability in market price and inadequate input among others were the major problem associated with Irish potato production in the study area. The study recommended that provision of storage facilities may help greatly in reducing damage of potatoes also farmers should be encourage to form cooperatives society or farmers groups to source inputs and sell their product collectively.

The study analysed the profitability of Irish potato production in Sardauna Local Government Area of Taraba State, Nigeria. Primary data were collected from 118 Irish potato farmers using purposive and random sampling techniques. The data were analysed using descriptive and inferential statistics. The result of the study revealed that majority (60.1%) of the respondents were in their prime age, 72.1% of the respondents were male and 49.2% were married. Most (94.1%) of the respondents had one form of education or the other while 85.6% of the respondents were small holder farmers. The result on the costs and returns revealed that Irish potato farming in the study area is profitable with a profit of N18, 131.57 per hectare. The return on Naira invested was N 0.18k. This Implies that for every N1 invested, N 0.18k was realised as profit. The result on the input output relationship reveals that seeds, fertilizer and educational level of the respondents were the main variables that have direct relationship with the output of Irish potato production in the study area. The major constraints affecting Irish potato production in the study area were identified as; lack of storage facilities, Problems of pest and diseases, high cost of labour, among others. The study recommend that modern storage techniques and facilities should be made available to the farmers at subsidize rate and there is need for extension agents and other agricultural specialists to visit the study area and proffer solution to the problem of pest and diseases while Irish potato farmers in the study area are encourage to form cooperative societies to enable them access credit facilities without hitch.
Potato (Solanum tubersom L.) is one of the most important food crops in developed as well as developing countries. This activity was conducted during the 2013 main cropping season at Daro Lebu and Oda Bultum districts of West Hararghe Zone to identify and select among potato varieties that are adaptable to local conditions and accepted by farmers and consumers at large and to generate knowledge and information that can contribute for the seed value chain development. A total of four farmers were participated on the experiment. Gudane, Bubu, Toluma, Bete and Local check varieties were evaluated on 25m 2 and 100m 2 plots at Daro Lebu and Oda Bultum districts, respectively. Economic data (cost of input and revenue obtained), agronomic data and farmer feedback/preference were collected. The collected data were analyzed through descriptive statistic (mean and standard deviation) and graphs by SPSS software and qualitatively. The agronomic result shows that the average total yield harvested from Gudene and Bubu varieties were 21 ton/ha and 20.24 ton/ha, respectively. In addition participants of field day were also select those varieties based on criteria's like disease reaction, tuber size, marketability, number of tubers and ways of giving tubers from one plant, color, perish ability, yield amount, sweetness and short time take during catering. Economically, Gudane and Bubu varieties was more beneficiary as compared to Bete, Toluma and Local variety, which were 83,500 Eth.birr and 77,420 Eth.birr, respectively. According to other agronomic data result shows that and farmer preference criteria like disease resistant, high yielder, larger tuber size, marketable, good color and high number of tuber and others, Gudane and Bubu varieties were selected as compared to Toluma, Bete and Local varieties. Therefore, Gudane and Bubu varieties will recommend for further scale up/out for Oda Bultum and Daro Lebu districts and others area which is similar agro-ecology to Oda Baso and Jilbo kebeles.

The highland of Bale is known with potato production, but post harvest quality of the crop is not emphasized yet. Therefore, this study was conducted to evaluate six potato varieties with the objective of assessing the effect of varieties and growing on tuber nutritional and process quality of potato grown in Sinana and Dinsho highlands of Bale. The experiment was laid out in randomized complete block design with three replications. The varieties showed highly significant (P<0.05) differences for all the parameters studied across the locations. The highest specific gravity, dry matter content and starch content (1.107, 26.61 and 19.19) were recorded from Dinsho location for Guddene variety while the lowest specific gravity, dry matter content and starch content (1.084, 19.41 and 14.61) were recorded from Sinana location for Ararsa variety. Most of the varieties were recorded as the highest values of specific gravity, dry matter and starch content at Dinsho indicating that it is an ideal location for potato production to be used for processing while Sinana is suitable for the production for home consumption. However, it is necessary to evaluate these varieties for a number of seasons and locations to recommend with high post harvest quality parameters required by the processors.

Characterization of potato production, marketing and utilization were undertaken in four zones of North Westren Amhara Region namely West Gojjam, East Gojjam, South Gonder and Awi based on their potato production on 158 farmers in 2010 to 2011. The main objective of the study was to characterize and document as well as to assess the challenges of existing potato production, marketing and utilization systems based on primary and secondary data. Potato is mainly produced in main, residual and irrigation production seasons in the study zones. Farmers plow their potato farm at least four times before planting and cultivate two to four times. They use an average potato seed tuber rate of about 2.008 tons per hectare. Farmers use local potato varieties for a long period of time and their average productivity is only 7.26 ton per hectare in main season production, and only 21.5% of farmers use improved potato varieties. Potato seed sources for farmers' are own production, market, research and Agriculture office. About 75% of the sample farmers store ware potato after harvest for about 3.84 months using floor, raised bed ("kott"), and in the soil. Half of the potato produced are consumed at home while the rest are reserved for seed and sold. Farmers consume potato in the form of boiled and stew. Major constraints of potato production include disease, soil nutrient depletion, moisture stress, frost, pest, lack of improved varieties, water shortage and lack of market access.
Growth and Productivity of Different Potato Cultivars

During the experimental years of 2017 and 2018 eight potato cultivars were evaluated for their growth traits and productivity in tuber yield. The potato cultivars used in these experimental seasons were; Bubu (as a standard check), Chiro, Gebisa, Belete, Gudene, Badasa Jarso and Dedafa. The first six consecutive potatoes are improved cultivars which were released by Ethiopian research institute and University while the last two potatoes were collected from farmers and cultivated as local (native) cultivars. The objective of this study was to compare the growth and productivity potato cultivars grown at eastern regions of Ethiopia. The results revealed that performance of improved potato cultivars were high in both evaluated yield related traits and average tuber yield. The performances of evaluated potatoes were not similar among cultivars and within cultivar throughout experimental seasons. The experimental design was a randomized block design in three replications. The field manag...

The potato (Solanum tuberosum L.) is one of the most common foods consumed in Rwanda and all over the world. However, the yields of potato remain low, ranging from 5 to 20 tons per ha in Rwanda. The average yield obtained during this research is 8.873 t per ha. This low potato yield is mainly caused by technical factors, including low seed quality, pests and diseases, agriculture input that are not well applied, and crop rotation. The objective of this study was to identify the main technical factors affecting potato production based on farmer perception in Musanze district of Rwanda. For this study, seven sectors of the district were selected, and in each sector, 27 potato farmers were randomly selected and interviewed using formal, informal, and expert interviews based on the prepared questionnaires. The qualitative and quantitative data were recorded and analysed using Microsoft Excel and STATA 14. Among the 192 farmers from all seven targeted sectors of the district, 17.19% used a formal seed system, while 82.81% used an informal seed system. The obtained results showed that the prevalence of diseases and pests such as late blight, bacteria wilt (BW) and aphids was perceived at 31.9, 68.8, and 86.8%, respectively. The study recommends an increase in awareness of certified seeds, their presence on the market, a reduced price for certified seeds, and the management of soil-borne diseases using appropriate crop rotation and biological and chemical control, among other things.

Potato is one of the most important food crops grown in mid and high altitude areas of Ethiopia. To meet the production need several potato genotypes have been introduced and evaluated at different areas of the country. However, the performances of different released potato varieties were not yet assessed in the study area. To this end, the present study was undertaken with the focus on determining the adaptability of Irish potato varieties for yield and yield components. It was conducted at Kaffa zone Adiyo District in Alarigeta experimental sub-station in 2013 and 2014 Belge cropping season. Seven improved potato varieties; namely Bule, Marachare, Wochecha, Dancha, Jallanie, Gudanie and Belete were used as treatment. Treatments were arranged in randomized complete block design with three replications. Average tuber diameter, average tuber number, average tuber weight, marketable tuber number, unmarketable tuber number, total tuber number, marketable tuber yield, unmarketable yield and total tuber yield data were recorded and submitted to analyze using SAS software version 9.0. Analysis of variance for each year showed significant (p< 0.05) difference among the varieties for all studied traits except Average tuber diameter and marketable tuber number in 2013, and Average tuber diameter and unmarketable tuber yield in 2014. The highest and consistent tuber yield was found in variety Belete (40.54 t/ha and 39.98 t/ha) in 2013 and 2014 respectively. Therefore, variety Belete, which was given high yield in both years, could be used instated of currently cultivating varieties to increase production and productivity of the crop for better enhancement of food security and livelihood income of the locality.
