Socioeconomic reflections on the development and performance of improved small grains : experiences from Zimbabwe / M.P. Mazhangara

Public ISBD Accompagne Drought-tolerant crops for Southern Africa Titre : Socioeconomic reflections on the development and performance of improved small grains : experiences from Zimbabwe Type de document : texte imprimé Auteurs : M.P. Mazhangara, Auteur Editeur : ICRISAT Année de publication : 1996 Importance : p 219-225 Langues : Anglais (eng) Catégories : SCIENCES AGRICOLES Mots-clés : ZIMBABWE  SORGHO  PETITE GRAINE Résumé : This paper outlines the development and the diffusion of new sorghum and millet varieties and documents the setbacks encountered in the process. The paper then reviews the performance of two improved, small grain varieties, PMV 2 (pearl millet) and SV 2 (sorghum), based on various studies that include the initial findings of the SADC/ICRISAT/DR&SS Small Grains Impact-Assessment Study under way in Zimbabwe in 1994. Both varieties were welcomed by farmers because they were high-yielding, of short duration and easy to thresh but farmers found PMV 2 very susceptible to bird damage. Concerning taste, both varieties were rated good but were less preferred to local landrace varieties, and both have limited storability due to their softness. Improved small grains, however, contribute to overall farm profitability. Issues arising from small-grains research in Zimbabwe are identified as (a) reducing the gap between yields obtained from research-managed plots and those of farmers, (b) the need to involve farmers in selecting for plant traits, (c) revitalizing agronomy programs and (d) the need for researchers to take an interest in the technology transfer process.
