| ABSTRACT: Allelopathy has become a paramount tool for controlling weeds in crop plants without deteriorating the environment. Allelopathic effects of sorghum aqueous extracts and sorghum powder on a single cross maize (Zea mays L.) hybrid “HC-8080” and a summer weed, jungle rice (Echinochloa colona L.) were assessed in the research laboratory of Agronomy, Faculty of Agriculture, Gomal University, Dera Ismail Khan, KPK, Pakistan. The treatments included: T1: control (untreated check), T2: sorghum aqueous extract at a rate of 5 mL kg-1 soil, T3: sorghum aqueous extract at a rate of 10 mL kg-1 soil, T4: sorghum aqueous extract at a rate of 15 mL kg-1 soil, T5: sorghum powder at a rate of 5 g kg-1 soil, T6: sorghum powder at a rate of 10 g kg-1 soil and T7:... |

| ABSTRACT: This study aimed to further explore that if coumarin and lavender’s extract, similar to greenhouse conditions, are phytotoxic towards some plant species under agronomic conditions. Before planting of maize, coumarin at 0, 250, 500, 1,000, 2,000, and 4,000 g h-1 and lavender’s aqueous extract at 0, 1,000, 2,000, 4,000, 8,000, and 16,000 mL h-1 were applied and incorporated into soil at a 3-5 cm depth. The density and biomass of weeds was significantly reduced by applying both compounds. The inhibition ability was also rate-dependent. Although the density and biomass of maize was also decreased at high rates, this crop showed higher tolerant to both compounds that all weeds. |

| The publication describes outcomes of a study conducted in 2007/08 to analyze the bottlenecks affecting the production and deployment of maize seed in eastern and southern Africa. The objectives of the study were to provide a better understanding of the factors limiting the production and deployment of improved maize seed in Africa, and to contribute to increasing the efficiency of variety release, seed production and seed dissemination for new drought tolerant maize varieties. The study identified a number of institutional bottlenecks affecting the maize seed value chain, in particular in the area of policy, credit availability, seed production, germplasm and marketing. To address these bottlenecks and improve the efficiency of seed production and... |

| In most developing countries, historically, the main strategy for improving the food sector has focused on increasing farm-level production. But in recent years, with the emphasis on value chain analysis, there has been much more focus on subsector studies, demand-driven approaches, and improving vertical coordination to assure product quality to final consumption markets. Millet, sorghum, and later rice were the traditional leading three cereal crops produced and consumed in Mali. Maize has trailed them for more than two decades, but from mid 1990s on, it has been produced and consumed in much larger quantities. Given the potentials of maize, developing and better organizing its subsector has the potential to not only increase revenues for maize farmers,... |

| CONGRESSO NACIONAL DE MILHO E SORGO, 16., 1986, Belo Horizonte.. |
| O XVI Congresso Nacional de Milho e Sorgo, realizado em Belo Horizonte, no período de 04 a 08 de agosto de 1986, foi uma promoçifo conjunta da EMBRAPA EMATER-MG e EPAMIG, e teve como convidados de honra o Exmo Sr. Ministro da Agricultura, Dr. lris Resende Machado e Exmo Sr. Secretário de Agricultura de Minas Gerais, Dr. Márjo Ramos Vilela. Desse evento participaram cerca de 600 profissionais ligados às áreas técnica, política e econômica das culturas de milho e sorgo. Desse modo, além da presença de pesquisadores, professores, extencionistas etc, também participaram representantes das indústrias alimentícias, de sementes, fertilizantes, defensivos e de máquinas e implementos agrícolas. Durante o congresso, foram apresentados trabalhos técnicos de diversas... |

| Background Head smut of maize, which is caused by Sporisorium reilianum f. sp. zeae (Kühn), is a serious disease in maize. In order to reveal the molecular mechanism of the resistance to head smut in maize, a microarray containing ~ 14,850 probes was used to monitor the gene expression profiles between a disease resistant near isogenic line (NIL) and a highly susceptible inbred line after S. reilianum was injected with an artificial inoculation method. Results Levels of expression for 3,532 genes accounting for 23.8% of the total probes changed after inoculation. Gene Ontology analysis revealed that the differentially expressed genes participated in physiological and biochemical pathways. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis... |
