Conventional vs. organic cropping systems: yield of crops and weeds in Mediterranean environment Organic Eprints
Campiglia, Enio; Mancinelli , Roberto; Radicetti, Emanuele.
Agriculture must meet the twin challenge of feeding a growing population while simultaneously of minimizing its global environmental impacts. The organic farming, which is a system aimed at producing food with minimal harm to ecosystems, is often proposed as a possible solution. However, critics argue that organic agriculture may give lower yields and therefore more land is required in order to produce the same amount of food of the conventional farms, resulting in more widespread deforestation and biodiversity loss, thus undermining the environmental benefits of organic practices. The long-term experiment was established in 2001 in order to compare organic vs. conventional cropping systems and inversion vs. non-inversion soil tillage. A 3-year crop...

COVER CROPS AND MULCHES INFLUENCE WEED COMMUNITY CHARACTERISTICS IN STRIP TILLED TOMATO (Solanum lycopersicon L.) Organic Eprints
Campiglia, Enio; Mancinelli , Roberto; Radicetti, Emanuele.
The aim of this poster is to investigate the effects that cover crop species and their residues may have on weed community composition in a winter cover crop-tomato sequence. Experiments were carried out at the experimental farm of Tuscia University from 2011 to 2013. The treatments consisted in: (i) 5 soil managements [three winter cover crop species (hairy vetch, phacelia, and white mustard), a winter fallow soil mulched with barley straw before tomato transplanting, and a winter fallow tilled before tomato transplanting (conventional)}; (ii) 2 levels of nitrogen fertilization applied on tomato [0 kg of N ha-1 (N0) and 100 kg of N ha-1 (N100)]; (iii) 2 levels of weed management applied on tomato [weed-free (WF) and weedy (We)]. Cover crop residues...

ECOLOGICAL WEED MANAGEMENT Organic Eprints
Radicetti, Emanuele.
Nowadays there is much concern over environmental and human health impacts on weed management practices which has led agricultural producers and scientists in many countries to seek innovative strategies for weed control. As weed management systems are being developed, ecological knowledge will become more and more important and the complexity of weed management must be considered. Therefore understanding weed-crop ecology will lead to more effective weed prevention, management, and control through a full range of factors regulating weed density, growth, and competitive ability. These alternative approaches for suppressing weed growth and reproduction is called “ecological weed management”. Ecological weed management involves the use of different types of...

Effects of cover crop residue management on yield and weed controlin processing tomato Organic Eprints
Campiglia, Enio; Mancinelli , Roberto; Radicetti, Emanuele.
The aim of this poster is to evaluate the effects of different subsidiary crop species and their residue management on weed control and fruit yield of a tomato crop in the Mediterranean environment of Central Italy. A field experiment was set up in September 2012 at the experimental farm of Tuscia University (UNITUS). A 2-year durum wheat – tomato sequence was adopted. The treatments consisted in: (i) 4 different cropping sequences (Fig. 1); (ii) 2 cover crop residue management [residues mowed and left in strips on soil surface in no-tillage (NT) and residues chopped and incorporated into the soil (T)]; (iii) 3 nitrogen fertilization levels to the durum wheat and tomato [0% (N0), 50% (N50), and 100% (N100) of total nitrogen recommended dose].

Evaluating spatial arrangement for durum wheat (Triticum durum Desf.) and subclover (Trifolium subterraneum L.) intercropping systems Organic Eprints
Campiglia, Enio; Mancinelli , Roberto; Radicetti, Emanuele; Baresel, Jörg Peter.
Cover crops and mulches can be used for increasing sustainability in winter cereal cropping systems. We performed a 2-year field experiment in Central Italy with the aim of finding a suitable spatial arrangement for durum wheat (Triticum durum Desf.) and subclover (Trifolium subterraneum L.) as a living mulch system in order to provide a high cereal grain yield and a sufficient subclover reseeding following the wheat harvest. Experimental treatments consisted of: (i) five cropping patterns [wheat and subclover mixed in the same row, with rows 15 cm apart (same row); 2 rows of wheat and 1 row of subclover at a distance of 10 cm between rows (narrow rows); 2 rows of wheat and 1 row of subclover with a distance of 10 cm between the wheat rows and 17.5 cm...

Influence of transplanter modifications and cover crop mulches on the production of summer vegetables in conservation tillage Organic Eprints
Campiglia, Enio; Mancinelli , Roberto; Radicetti, Emanuele; Ferrari, Francesco.
The aim of this poster is to develop a vegetable transplanter that is capable of working in no-tillage conditions and in presence of organic mulches which cover the soil. The following requirements should be considered for built a transplanter able to work in no-tillage conditions: - An adequate structure and implements that can transplant under the most challenging conditions; - The possibility of placing vegetable seedlings in areas with high amounts of residues without disturbing the soil more than necessary; - The creation of a furrow for proper seedling placement; - Being able to cover the vegetable root system with soil in presence of a superficial mulch layer.

Multi-Environments Experiment (MEE) UNITUS Organic Eprints
Campiglia, Enio; Mancinelli, Roberto; Radicetti, Emanuele.
Unsustainable farming practices, including soil tillage intensification and heavy use of agrochemicals, have an adverse impact on natural resources, biodiversity and the environment. Therefore, there is a need to improve actual agricultural practices. The introduction of living mulches could be an efficient tool in order to stabilize crop yields, improve soil characteristics, and reduce external agricultural inputs such as herbicides and fertilizers. The overall objective of this experiment is to improve understanding and use of subsidiary crops in conservation agriculture systems under the Mediterranean environment of central Italy. Field experiment was set up in September 2012 at the experimental farm of Tuscia University (UNITUS). A 2-year durum...

Optimizing spatial arrangement for durum wheat (Triticum durum Desf.) and subclover (Trifolium subterraneum L.) intercropping system Organic Eprints
Campiglia , Enio; Mancinelli , Roberto; Radicetti, Emanuele; Baresel, Jörg Peter.
The aim of this poster is to find a suitable spatial arrangement for the subclover living mulch-durum wheat system in order to provide a high cereal grain yield and a sufficient subclover reseeding after wheat harvesting. The study was carried out at the experimental farm of Tuscia University from 2011 to 2013. Field experiments included: (i) 5 cropping systems including the monoculture of durum wheat and subclover and three different durum wheat/subclover intercropping spatial arrangements (Fig. 1); (ii) 2 nitrogen fertilization levels (0 and 100 kg ha-1 of N, hereafter called N0 and N100, respectively); (iii) 2 weed managements [weed-free (WF) and weedy (We)]. The wheat planting density was 400 seeds m-2 regardless the cropping system, while the...
