Cassava (Manihot esculenta Crantz) is an important food security crop in many parts of the developing world. The crop?s high yield potential and multitude of uses?both for nutrition and processing?render cassava a promising driver for the development of rural value chains. It is traditionally propagated from stem cuttings of up to 30 cm in length, giving a multiplication rate as low as 1:10. Propagating cassava traditionally is very inefficient, which leads to challenges in the production and distribution of quality planting material and improved cultivars, greatly limiting the impact of investments in crop breeding. The work described in the present study aimed to develop a seed treatment approach to facilitate the use of shorter seed pieces, increasing the multiplication rate of cassava and thus making the crop?s seed systems more efficient. After several tests, formulation was identified, consisting of thiamethoxam 21 g ha-1, mefenoxam 1.0 g ha-1, fludioxonil 1.3 g ha-1, thiabendazole 7.5 g ha-1 and Latex 2% as a binder. Plant growing from seed pieces treated with this formulation displayed increased crop establishment and early crop vigor, leading to an improved productivity throughout a full growing cycle. This allowed to reduce the cassava seed piece size to 8 cm with no negative effects on germination and crop establishment, leading to yields comparable to those from untreated 16 cm pieces. This, in turn, will allow to increase the multiplication ratio of cassava by a factor of up to 3. Notably, this was possible under regular field conditions and independently of any specialised treatment facilities. Compared with existing seed production protocols, the increased multiplication rates allowed for efficiency gains of between 1 to 1.9 years compared to conventional five-year cycles. We believe that the technology described here holds considerable promise for developing more reliable and remunerative delivery channels for quality cassava planting material and improved genetics.

A Embrapa Soja e a Embrapa Negocios Tecnologicos vem desenvolvendo trabalho de difusao de cultivares de soja desde a safra 1989/90. O objetivo do trabalho e apresentar, para tecnicos e produtores, as vantagens comparativas (adaptabilidade produtiva e resistencia a doencas) das cultivares desenvolvidas pela Embrapa Soja, quando comparadas com as cultivares em uso pelos agricultores. O projeto vem sendo realizado junto a cooperativas e produtores de sementes e consiste, basicamente, na realizacao de uma reuniao de planejamento para a instalacao de Unidades Demostrattivas-UDs, acompanhamento da UD por parte dos pesquisadores da Embrapa, realizacao de Dias de Campo e realizacao de uma reuniao de avaliacao onde sao discutidos pontos positivos e negativos do trabalho. Na safra 1998/99 foram realizados 19 Dias de Campo, com a participacao de 7.712 pessoas, entre agricultores e tecnicos. Paralelamente a este trabalho, tambem foram distribuidas a empresas previamente cadastradas, 80 colecoes com as cultivares da Embrapa Soja, para a instalacao de UDs. Nesses, locais foram realizados 25 Dias de Campo, com a participacao de 11.422 pessoas. A participacao das cultivares da Embrapa Soja, no total da semente produzida no Parana, aumentou de 3% na safra 1989/90, para 63% na safra 1997/98 e manteve-se nesse percentual na safra 1998/99. |
