Legumes in 21st century Europe: present and future importance in agri-food systems? New challenges for reseach.

2013

Intensification of agriculture since 1950 has globally led to the decline of grain legume crops, which currently represent less than 3 % of arable crops in France and Europe. Nevertheless, legumes have several major assets (i) as plant proteins for animal feed and human food and (ii) as plants fixing atmospheric N2 and thereby saving nitrogen inputs in cropping systems, and (iii) as diversification crops. The analysis of forage and grain legume producing systems in France showed that the dominant system results in a lock-in of the different factors limiting legume insertion into the current systems. But legumes could have a major role to play in the agroecological transition towards more su…

The green granary of the Empire? Insights into olive agroforestry in Sicily (Italy) from the Roman past and the present

2023

Groves with ancient olive trees (Olea europaea L.) could be considered remnants of old agroforestry systems. Anything but static, these agro-ecosystems have undergone drastic transformational processes in Mediterranean countries, where abandonment or intensification have been observed far more than continuity, expansion or renaissance, leading to environmental degradation of rural areas. Starting from this assumption and inspired by historical ecology and historical geography, we consider centuries-old olive trees as living archives of human-nature interactions and are thus proxies of past agroforestry. Our aim is to better understand what has driven dynamics of change and persistence, happ…

Harnessing productivity potential and rehabilitation of degraded sodic lands through Jatropha based intercropping systems

2016

Abstract This paper evaluates an intercropping model with J atropha curcas L. (JCL) as an alternative crop on degraded sodic land in north India. Monoculture of JCL has not proven economically viable in India in view of its poor yield; therefore, intercrops in between JCL plantations were tried to optimize land use efficiency. The results revealed that the planting of JCL at 3 × 3 m spacing with inter-cultivation of sweet basil–matricaria (SB-M) cropping system for four years was more economically viable than planting at 3 × 2 m spacing and the other rotations tested in the study. Improvements in soil properties in terms of soil pH, EC and organic carbon were found with the SB-M cropping sy…

Effects of Inter-cropping and a Herbicide on Management of Striga hermonthica on Sorghum

2017

Aims: The present work was undertaken to determine the effects of the herbicide chlorsulfuron and intercropping sorghum (cv.Wad-Ahmed) with cowpea (T100K-901-6 cv.) on S. hermonthica incidence and sorghum growth. Study Design: Randomized Complete Block Design (RCBD) with four replicates. Place and Duration of Study: A series of laboratory and greenhouse experiments was undertaken at the College of Agricultural Studies, Sudan University of Science and Technology (SUST) at Shambat, during the season 2013/2014. Methodology: Striga free or infested soil was placed in plastic pots (9 cm i .d) with perforations at the bottoms. Pots filled with Striga free soil (0 mg) were included as control for …

Sustainable production of fennel and dill by intercropping

2008

Intercropping is claimed to be one of the most significant cropping techniques in sustainable agriculture, and much research and many reviews attribute to its utilization a number of environmental benefits, from promoting land biodiversity to diversifying agricultural outcome. In this sense, intercropping is thought to be a useful means of minimizing the risks of agricultural production in many environments, including those typical of under-developed or marginal areas. In order to validate this hypothesis in a representative area of the semiarid Mediterranean environment, we evaluated the possibility of growing dill and fennel, both belonging to the family Apiaceae, in temporary intercroppi…

Forage yield and N2 fixation of Trifolium alexandrinum in pure stand and in mixture with Lolium multiflorum.

2010

The efficiency of grass-legume intercrop systems is affected by various agronomic factors such as crop density, plant spacing and arrangement that may alter the competitive relationships between component crops. This study was aimed to evaluate yield, N concentration, and symbiotic N2 fixation of berseem clover (Trifolium alexandrinum L.) grown in pure stand or in mixture with annual ryegrass (Lolium multiflorum Lam) either in alternating rows or in the same row. The experiment was conducted in two consecutive growing seasons in a semi-arid Mediterranean environment (Sicily, Italy). Dry matter (DM) yields were similar in the mixed stands and in the berseem pure stand; the annual ryegrass pu…

Mediterranean forage legumes grown alone or in mixture with annual ryegrass: biomass production, N2 fixation, and indices of intercrop efficiency

2016

Aims: To evaluate the productivity and N2 fixation of a range of Mediterranean forage legume species as well as their ability to be grown in mixture with a forage grass, and to verify whether N transfer occurs from the legume to the non-legume component of the mixtures and, if so, to what extent this process is affected by legume species. Methods: Seven legume species (Hedysarum coronarium L., Medicago scutellata L., Trifolium resupinatum L., Trifolium squarrosum L., Trigonella foenum-graecum L., Vicia sativa L., Vicia villosa Roth) were grown alone or in mixture with annual ryegrass (Lolium multiflorum L.). Biomass and N yields and biological N2 fixation (15N dilution technique) were measu…
