A multistage sampling technique was employed to select a total of 200 respondents from Potiskum and Fune </em><em>Local Government Areas </em><em>for the study. Data collected were analysed using&nbsp;frequency distribution, means and percentages. A Stochastic Frontier Production Function which incorporated inefficiency causes were estimated using Maximum Likelihood Estimation technique. </em><em>The results of the stochastic frontier function analyses revealed a mean technical efficiencies levels of 74%, implying that there was scope for increasing efficiencies by 26%. The main sources of technical inefficiencies were years of farming experience, extension contact, membership of cooperative societies, amount of credit obtained and educational level. The study recommends that extension contact, years of cooperative membership and access to credit were the sources of the inefficiencies and should be addressed through adequately trained and equipped extension workers, right use of credit facilities and the formation of cooperative societies and making membership a condition for microcredit benefit.</em></p> OKPACHU, S.

This paper intended to review warm season garden vegetable seed production. Ethiopia has diverse agro-ecologies for production of warm season vegetables like tomato, chili and sweet pepper as well as green beans. The high demand for horticultural products, availability of suitable agro-ecology, and increasing irrigation schemes development focusing on vegetable production, have resulted in increased demand for quality seeds of improved varieties of various vegetable crops so as to serve further boost in local production, albeit with increased investment. The increase in import of vegetable seed is attributed to expansion of irrigated vegetable production both for local consumption and export. This implies that there is a substantial demand for vegetable seeds and increase in vegetable production in Ethiopia within the reference period. The development of the vegetable sub-sector is one of the priority areas in the agricultural development strategy of Ethiopia (Ethiopian Investment Agency, 2008; 2012). Commonly grown by small scale farmers and commercial growers both during rainy and off-seasons. Since, there is no organization involved in the multiplication of vegetable seeds, access of these crop varieties is very limited. The demand is rapidly increasing. Several high yielding varieties of vegetables with improved technologies have been developed however availability of quality seed with insufficient quantities is a major constraints. In order to meet this challenge there is need to initial seeds of released varieties are multiplied and maintain annually by understand and document farmers’ preference for vegetable, variety/varieties of the preferred type(s), criteria for their preference based on their perceptions; and popularize the improved seed production packages in vegetable crops, which would in turn provide comprehensive knowledge to the seed growers regarding the recent advances in technologies.</p> Melkam Anteneh Alemu Copyright (c) 2019 International Journal For Research In Agricultural And Food Science (ISSN: 2208-2719) Sun, 30 Jun 2019 07:29:55 +0000 Nematicidal Efficiency of 10 % Emulsifiable Concentrate Formulation of Propolis on Root-Knot Nematode Meloidogyne Spp. <p>Propolis is a red or brown resinous substance collected by honeybees from tree buds with a broad spectrum of biological properties. It was formulated as an emulsifiable concentrate (EC); the new formulation was subjected to all tests specified by pesticides specialized organizations like WHO and FAO. It passed successfully all tests and evaluated biologically against second stage larvae of Root-Knot nematode <em>Meloidogyne Spp. </em>under greenhouse conditions<em>.</em> The new formula inhibited markedly the ability of the 2<sup>nd</sup> stage larvae of Root-Knot nematode<em> Meloidogyne Spp</em>. to penetrate eggplant roots in addition to the marked decrease in the number of galls obtained from the calculations of root gall index (RGI). The obtained results showed that it could be possible to use propolis emulsifiable concentrate formulation in the field of nematode control after carrying out the complementary experiments in the future.</p> Saad.
