Cassava is a root crop grown and consumed in south western part of Ethiopia. A survey was conducted to assess the production status, processing and utilization of cassava in three zones in South Western part of Ethiopia. A total of 63 farmers from five Cassava producing Districts were randomly selected for interview. A well-structured questionnaire was administered to individual respondent. The survey result showed that most of the farmers on average allocated less than 0.25ha of land for cassava production and none of the respondents were used improved cassava varieties. More than 86% of the farmers sold fresh cassava while others sold after processing. Of the interviewed farmers 98.4% of the respondents had awareness about hydrogen cyanide content of cassava and conducted different removal measures. More than half of the interviewed farmers responded that most of cassava produced in the area was used for home consumption. Less than 40% of them were used for both market and home consumption. Of the total farmers, 53% of the farmers consumed cassava by boiling and frying, while the others consume either by boiling or frying.

The study examined the costs and returns to bio-fortified cassava production and forecast the future farm size of bio-fortified cassava production in Oyo State, Nigeria. A multistage sampling technique was used to select our respondents. Primary data were used for the study which were collected through a well-structured questionnaire. Data collected were analyzed using descriptive, Markov chain, and budgetary analysis. The result of the study showed that TMS 01/0593, TMS 01/0539 and TMS 01/0220 were the mostly grown varies of bio-fortified cassava varieties in Oyo State, Nigeria. The result of the budgetary analysis showed that the average net return (net farm income) from the production of bio-fortified cassava was ₦196710.95 with RORI of 224.95%. The result revealed that at 35% increase in cost of production, the rate of return on investment dropped to 140.70% in which the investment will not be viable. The bio-fortified cassava farmers have a great potential to boost production through increases in farm sizes of the bio-fortified cassava famers until the year 2026 when equilibrium would be attained at about 2.85ha. In order to adequately achieve these goals, more improved varieties of bio-fortified cassava should be provided. Consequently, infrastructures should be put in place to help boost farmers moral in their cause of production.

RAPD (Randomly Amplified Polymorphic DNA) is an indicator for high and stable polymorphism, widely used in the study of the diversity of cassava. In this paper, the results of using 20 polymorphic primers OPK combined with the establishment of the phylogenetic tree to analyze the genetic diversity of 26 cassava varieties with different responses to waterlogging conditions by using the RAPD-PCR technique were presented. The purpose of this experiment was to show the genetic relevance of the studied cassava varieties. The results showed that the flood tolerance of cassava was not related to the polymorphism and branching characteristics of the stem. This information may be use as a basis for selecting flood-tolerant cassava varieties for cassava production, as well as the basis for selecting genetically different parents for breeding.

The study investigated determinants of adoption of recommended cassava production technologies among male farmers in Nasarawa State. Multi-stage sampling technique was employed for the selection of the respondent. Structured questionnaire was used for data collection. The data were collected from 60 male cassava farmers selected from 6 out of 13 LGAs in the State. They were Karu, Kokona, Akwanga, NasarawaEggon, Lafia and Obi. Data were analysed with both descriptive and inferential statistics. Descriptive statistics such as frequency tables, and percentage were used to describe socio-economic characteristics of the respondents. Logit regression model was used to estimate the determinants of adoption of these practices. The results showed that awareness and adoption of these practices were very high (Awareness of all the practices ranges from 90% to 98.3% while the adoption is from 63.3% to 90%). Factors that positively and significantly influenced adoption by male farmers were income (p=0.01) and extension contact (p=0.1). The conclusion was that men made remarkable contribution in cassava production. It was recommended that Governments at all levels formulate policies aimed at encouraging and motivating male cassava farmers. Provision of loans to male farmers and subsidizing of inputs should be ae necessary. Cassava processing industries should be established to add value and increase income.Keywords: Adoption, Cassava Technologies, Male farmers.

ABSTRACTThe life history and population growth parameters of mealybug Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae) on two cassava varieties. The development, reproduction, and population growth parameters of the cassava mealybug, Phenacoccus manihoti Matile-Ferrero (Hemiptera: Pseudococcidae) on two cassava varieties were studied in laboratory. The varieties tested were UJ-5 with high cyanide content (>100 mg per kg) dan Adira-1 with low cyanide content (27.5 mg per kg).  Our research revealed that P. manihoti performances were highly affected by cassava varieties.  Incubation period of eggs of P. manihoti were 7.93 ±  0.09 and 8.33 ± 0.11 days, nymphal development periode 12.32±0.13 and 15.67 ± 0.13 days, respectively on UJ-5 and Adira-1. Fecundity averaged 386.37 ± 5.83 on UJ-5 and 318.67±2.81 eggs on Adira-1. Intrinsic rate of increase (rm) were  0.258 ± 0.001 on UJ-5 and  0.220 ± 0.001 on Adira-1. Mean generation time (T) on UJ-5 and Adira-1 were 22.795 ± 0.050 and 25.532 ± 0.047 days, repectively. Our findings showed that variety UJ-5 was more suitable for development and population growth of the cassava mealybug.

Growing different crop species in combination with mushroom, honey bee, livestock around homestead is an ancient practice of home gardening where marginal land, labour, limited capital with simple tools and technology are used. A survey was conducted in Purkot VDC of Tanahun district in April 2015 with the purpose of assessing the status and annual income of home garden. Data was collected through purposive method by using structured questionnaire at four wards of the VDC. The economic return was assessed through calculating the local retail value of the product without considering cost associated with it. The average annual income of home garden was NRs. 33528.65 from average 377.78 m2 (0.76 Ropani) home garden, derived from cultivation of vegetables, fruits, legumes, medicinal & aromatic plants and cereals. About 65 % household involved in multistoried gardening with the objective of home consumption (66.7 %). Home garden of study area was truly vegetable based (100 %). Income of home garden was determined by objectives of gardening, education level of respondents and type of species grown. The key problem of home garden was insufficient water (81.2 % of cases), incidence of disease insect/pest (66.7 % of cases), weather and climatic impact (56.2 %), animal trespass (41.7 %) and labour insufficiency in gardening (31.2 %).
