| Seed germination of fig seeds is important for obtain seedlings with high variability in breeding studies, and for producing mosaic virus-free seedlings. This experiment was carried out to evaluated the effects of several treatments (priming with water for 24h, GA3 at 500 and 1000 ppm for 24h, 3% KNO3 for 24h, and stratification at 4°C for 7, 14 and 21 days) on seed germination and emergence of ‘Bursa Siyahı’ and ‘Sarılop’ fig cultivars. The application of GA3 increased the germination and emergence of these fig seeds. The highest percentages of germination and emergence were obtained with GA3 at 500 or 1000 ppm for both cultivars. The seed germination and emergence of the cultivar ‘Bursa Siyahı’ were higher than observed with the ‘Sarılop’. The... |

| La uchuva (Physalis peruviana L.) es un importante cultivo que posee cualidades medicinales y nutricionales, y es una opción viable de producción y exportación para productores de México, por lo que la investigación se hace necesaria. Entre los temas prioritarios a investigar se tiene formas de propagación, nutrición óptima y ambientes adecuados para su producción. El objetivo de esta investigación fue evaluar el efecto del ambiente, origen de planta y la relación NH4+/NO3- sobre la morfología, rendimiento y calidad fruto en dos estadios de maduración de Physalis peruviana L. El estudio se desarrolló en el Colegio de Postgraduados, Campus Montecillo, México y se utilizó un diseño factorial completamente al azar con cinco repeticiones, donde se tuvieron... |

| There have been numerous episodes of widespread adoption of improved seed and long-term achievements in the development of the maize seed industry in Sub-Saharan Africa. This summary takes a circumspect view of technical change in maize production. Adoption of improved seed has continued to rise gradually, now representing an estimated 44 percent of maize area in Eastern and Southern Africa (outside South Africa), and 60 percent of maize area in West and Central Africa. Use of fertilizer and restorative crop management practices remains relatively low and inefficient. An array of extension models has been tested and a combination of approaches will be needed to reach maize producers in heterogeneous agricultural environments. Yield growth overall has been... |
