“…This may be due to changes in the overall population of the antagonistic resident soil bacteria and fungi which compete with the pathogens as well as changes in the amount and availability of soil nutrients to plants associated with CMs application as mentioned by Abo-Elyousr et al (2014). Aryantha and Guest (2006) reported that the beneficial effects induced by composts are due to increase the activities of soil microbes in the plant rhizosphere. Some of them produce plant growth hormones and stimulate plant growth directly, while others produce natural chelators called siderophores that keep iron at a high level in available form to plant in soil.…”

his study deals with in vitro, greenhouse and field efficacy of plant growth promoting rhizobacteria (PGPR) strains and date palm leaves compost (DPLC) for controlling faba bean wilt caused by Fusarium oxysporum. Date palm leaves compost at 2,4,6,8,10 ton/feddan significantly decreased wilt severity under artificial inoculation with Fusarium oxysporum in pot and the natural infection in the field, as well as increased growth and yield parameters during 2013/2014 growing season. Date palm leaves compost at 8 ton/feddan recorded the highest protection against faba bean wilt as well as gave the highest increase of plant growth and yield parameters. On the other hand, PGPR, viz. Bacillus megaterium, B. cereus and Pseudomonas fluorescens individually or in combination significantly increased the efficacy of DPLC for controlling Fusarium wilt of faba bean more than application of DPLC alone under greenhouse and field conditions during both growing seasons (2014/2015 and 2015/2016) as well as increased nodulation, plant growth and yield parameters. Application mixture of PGPR strains together with DPLC at 8 ton/feddan recorded the highest reduction to wilt severity with the highest increase of nodulations, plant growth and yield parameters.

“…Organic matter (OM)-mediated suppression of soil borne diseases in field soils caused by pathogenic species of Pythium and Phytophthora has been reported for a variety of plant species and organic substrates (Lewis et al, 1996;Lourd et al, 1987). Soil amendment with bio-agent fortified compost can modify the microbial community composition by enhancing the competition for nutrients or antagonism or mycoparasitism among microbes (Aryantha and Guest, 2006). In addition, beneficial microbes activate the plant to defend themself, a phenomenon termed 'induced systemic resistance' (Conrath et al, 2002;Van-Loon, 2007).…”

French bean (Phaseolus vulgaris L.) production is adversely affected by many pathogens and insect-pests worldwide. In the present investigation, effect of different bio-fortified composts, organic amendments, botanicals and pesticides were evaluated against diseases and insect- pests of french bean. The results showed that seed treatment and drenching with Trichoderma harzianum strain 11, followed by soil application of fortified farmyard manure resulted in the lowest root rot incidence, highest germination, vigour and yield in french bean. In another set of experiment, soil incorporation of Parthenium hysterophorus, Urtica dioicaandLantana camarawere found to reduce root rot incidence with high germination and pod yield. Among the bioproducts and botanicals tested, foliar spray of cow dung extract (50%) reduced angular leaf spot, rust and bacterial blight severity by 51, 69 and 25 per cent, respectively. Among the fungicides, foliar application of azoxystrobin 23 SC (0.1%) and difenoconazole 25EC (0.025%), also reduced angular leaf spot and rust severity by 93 and 90 per cent, respectively. Among different insect pest management strategies under field conditions, cartap hydrochloride and batain seed extract registered low sucking bug (Chauliops choprai) population. Integrated approaches including bio-agents, botanicals along with chemicals for managing these diseases and insect-pests were found appropriate options. Out of six different IPM modules evaluated, seed treatment with carbendazim along with foliar spray of 0.1% azoxystrobin and cartap hydrochloride resulted in lowest root rot, rust, angular leaf spot, bacterial blight and Chaulopsis choprai bug population in French bean.

“…In addition, a diversity of families, species, varieties and genetic diversity will increase the capacity of the system to survive and prosper in different climate conditions [110][111][112] thus increasing its resilience [113]. Diversity can include measures such as micorrization [114] to increase survival rates; composted manure [115,116] and the plant Phlomis purpurea to control pests [117]; diversification of fodder using edible shrubs adapted to drought [118] or increasing species richness to increase productivity [119]. c.…”

“…One important attribute of this organization of measures inside strategies is that a given measure can easily fit in more than one strategy. For example, applying composted manure to soil serves, on one hand, as a Water and Soil strategy, since it increases, by 25%, the capacity of water retention of the soil [103], and, on the other hand, composted manure is a strategy of Diversity, since the diversity of microorganisms in the compost serve as a pest control, namely with an efficiency of 39-76% in controlling P. cinnamon, an oomycete that kills cork and holm oaks [115]. This strengthens the understanding of the different functions of adaptation measures, by clarifying the multiple positive effects of an adaptation measure by placing it in different strategies, therefore supporting different objectives.…”

Planning the adaptation of agriculture and forestry landscapes to climate change remains challenging due to the need for integrating substantial amounts of information. This information ranges from climate scenarios, geographical site information, socio-economic data and several possible adaptation measures. Thus, there is an urgent need to have a framework that is capable of organizing adaptation strategies and measures in the agriculture and forestry sectors in Mediterranean climatic regions. Additionally, this framework should provide a cause effect relation with climate vulnerability to adequately support the development of adaptation planning at municipal and local (farm) level. In this context, we propose to test and evaluate a framework for climate adaptation of the agriculture and forestry sectors, based on the local causal-effect relation between adaptation strategies and measures and the level of vulnerability reduction achieved for Mediterranean areas. The framework was developed based on the combination of the DPSIR (Driving forces, Pressures, State, Impacts, Responses) and Vulnerability frameworks and reviewed 162 practical adaptation measures, further organized into strategies, complemented by a set of efficacy indicators. The framework was tested with 70 stakeholders in six stakeholder workshops for the planning of two farms and one municipal climate adaptation study, that are now in actual implementation and monitoring. The framework is composed by a set of eight adaptation strategies in which adaptation measures are clustered and assessed using efficacy indicators. In the evaluation of the adaptation framework, 96% of stakeholders considered its content as good or very good and 89% considered the final outcomes as good or very good. Finally, the framework was also used to assess and compare the adaptation strategies and measures presented in the climate adaptation plans of the three case studies. On average, 52.2% of the adaptation measures selected by the three case studies are dedicated to Ecosystem Resilience, 30.9% to Adaptive Capacity, 9.1% to Microclimates, 7.4% to Protection, and 0.3% to Mitigation strategies. This framework was considered effective in supporting adaptation planning at farm and municipal levels and useful to assess and compare adaptation plans in the frame of vulnerability reduction. Future studies can further contribute to support adaptation planning in these sectors by using, developing and streamlining this framework to additional and different socio-ecological contexts.
