Oral presentations I: Agronomic practices

In this morning’s oral presentations on Agronomic Practices, Wolfgang Pfingst opened the session with his study on the cultivation, processing and marketing of the endangered orchid species Dendrobium chrysotoxum in China. Their honey-flavored flowers are a high priced neglected non-timber food product that could bring additional income to farmers. By selling them through the channel of a local Chinese enterprise, the demand on the European market could be met. Camilo Lesmes Fabian designed a new model for dermal and inhalation exposure assessment of pesticide application in Colombia since existing models being developed in Europe are not applicable for the Colombian conditions. His dynamic model includes working tasks, environmental compartments, protection and exposure concentrations. Ali Mokhtassi-Bidgoli’s study took place within the wheat production project in Iran in order to develop a crop production system that minimizes energy input. In short, most of the energy use comes from non-renewable energy. Kibet Ngetich compared three different ethnic groups in the Mau Escarpment, Kenya for their adoption of organic farming in crop production. Concluding, there’s an urgent need for ethnically focused approaches of introducing organic farming. Tropentag 2010 - Oral Session I Mazen Alkhateeb’s study on factors affecting olive production in Syrian drylands called for growing Sourani and Qaisi varieties that enhance average production. Further, sufficient irrigation and access to mass media are needed. He recommends establishing an irrigation water schedule, improved extension services on the proper fertilizer application and marketing through cooperatives. Finally Muhammad Qasim shared his knowledge on the contribution of improved rain-fed wheat productivity towards food security. An increase in farm size and seed quantity could increase the technical efficiency and hence wheat yield. In addition, cheap credit schemes with crop insurance, effective extension services and water conservation among others should be established.
