Agricultural extension messages using video on portable devices increase knowledge about seed selection, storage and handling among smallholder potato farmers in southwestern Uganda Campenhout, B. van; Vandevelde, S.; Walukano, W.; Asten, Piet J.A. van (2017-01-25)To feed a growing population, agricultural productivity needs to increase dramatically. Agricultural extension information, with its public, non-rival nature, is generally undersupplied, and public provision remains challenging. In this study, simple agricultural extension video messages, delivered through Android tablets, were tested in the field to determine if they increased farmers’ knowledge of recommended practices on (i) potato seed selection and (ii) seed storage and handling among a sample ...
Unexploited yield and profitability potentials of improved varietal technologies: the case of hybrid maize in Western Ethiopia Alene, Arega D. (International Institute of Tropical Agriculture, 2007)In view of the considerable potential for increasing food production through the generation and use of new agricultural technology, many developing countries have invested in agricultural research and extension. However, the issue of whether he intended production gains from new technologies have actually been realized by poor farmers has received little or no attention. This peruseda stochastic frontier efficiency decomposition methodology to derive the technical, allocative, and economic ...
Hatzenbuehler, P.L.; Abbott, Philip C.; Abdoulaye, Tahirou (2017-06)The absence of an agricultural census in Nigeria means that samples for surveys to estimate agricultural production are obtained from a non-comprehensive, non-representative set of farms. Therefore, aggregate production data quality is questioned. The methods employed herein provide a new way to empirically evaluate the quality of agricultural production estimates. Two objective types of data, namely the normalised difference vegetation index (NDVI), a satellite remote-sensing measure of intertemporal ...
