Application of organic bio-fertilizer technology to improve the sustainability of date palm production and cultivation

 

The use of mineral fertilizers, pesticides and irrigation have a strong impact on livelihoods and the environment. The project aims to develop a novel organic bio-fertilizer technology which will contribute to a more sustainable and resilient agriculture.

About the project

Background

Date palm is an important crop in Morocco, Tunisia, and in many other drylands of the world with a high agricultural, economic and cultural value. The harsh environmental conditions of those areas, which are further accelerated by climate change and the spread of root diseases, are threatening date palm propagation and cultivation. As a consequence, two thirds of all date palms were destroyed in Morocco during the last decades, causing substantial economic and ecological damages. To overcome the growth limitations, current date palm production and cultivation regularly involves high inputs of mineral fertilizers, pesticides and irrigation. However, these high external inputs strongly impact the environment and livelihoods, are cost intensive, not resilient and thus not sustainable.

Objectives

The project aims at establishing a novel organic bio-fertilizer technology, combining the application of native beneficial soil microorganisms during tissue culture and field propagation of date palms, together with adapted agricultural management practices using organic amendments and intercropping with leguminous nitrogen-fixing crops. As bio-fertilizers, arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR) are in focus. A culture collection of native AMF and PGPR, isolated from date palm roots and rhizosphere, will be established, and strains selected for date palm growth promotion, nutrient acquisition and pathogen suppression will subsequently be used as bio-fertilizers. Customized propagation and application techniques of bio-fertilizers will be elaborated such as modern in-vitro methods suitable for tissue culture laboratories and low-tech, knowledge-rich approaches for smallholder farmers. The technology, integrating the use of organic amendments and leguminous intercrops, will be developed in a participatory approach, working at laboratory, on-station and on-farm scale. As part of an innovation platform, aims and problems of date palm producers (tissue culture laboratories, smallholder farmers and farmers’ organisations) will be targeted in order to align them with the research process. Gained knowledge on technical and methodological innovations will be disseminated to a broader circle of stakeholders including regional and national agricultural agencies in order to influence their operational procedures.

Relevance

The proposed organic bio-fertilizer technology will contribute to more sustainable, resilient agriculture, safeguarding natural resources. It will help to maintain and increase date palm production, and to counteract the on-going land degradation and desertification of dryland soils. Thus, rural livelihoods will be improved, and poverty-driven migration to urban centres will decrease. It is anticipated that the knowledge gained in this project in Morocco and Tunisia can be transferred to other areas where date palm represents a major crop.
