“…In this case, the quadratic equation estimated rational N fertilisation rates needed to induce the maximum GPC (14.93% and 14.68% for urea and calcium nitrate, respectively) only in 2011 (see b2, Figure 3A) with values from 170.2 to 175.3 kg N ha -1 . Such values seem slightly higher than those required to achieve the maximum grain yield, confirming previous findings (Garrido-Lestache et al, 2004). However, similarly to the results of Ryan et al (1997) and Lloveras et al (2001) in Mediterranean conditions, we did not generally observe any additional response of GPC at over 150 kg N ha -1 .…”

“…Regardless to N-form, yield generally increased as N rates raised up to 150 kg N ha -1 (Figure 2A and B). As already reported by Garrido-Lestache et al (2004), this was particularly noticeable in the wettest year (2011), whilst in drier year (2012) the response was only recorded at rates up to 100 kg N ha -1 , especially for calcium nitrate. Moreover, we observed slightly higher yields in 2012 with respect to 2011 as well as a greater effect of calcium nitrate than urea.…”

“…Normally, yield and grain protein content is negatively correlated principally due to the dilution effect (Triboi and Triboi-Blondel, 2002;Stagnari et al, 2013). Nevertheless, this does not imply that higher grain protein cannot be obtained at high-yield levels, as we found a simultaneously increase in both yield and GPC (Garrido-Lestache et al, 2004), probably as a results of an efficient N translocation to the developing grains.…”

Nitrogen fertilisation of durum wheat: a case study in Mediterranean area during transition to conservation agriculture

Nitrogen (N) nutrition plays a key role for high yields and quality in durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husn); in Mediterranean environments, data regarding N fertilisation management during the transition phase to conservation agriculture (CA) are limited. The aim of this work was to study the effects of N fertiliser forms and rates on yield and some quality traits of durum wheat, during the transition period to CA in Mediterranean areas; moreover, indication on the recommendable N form/rate combinations have been given. Field trials were carried out in south of Italy, during the first two years of transition to CA (from 2010 to 2012) in a durum wheat-based rotation. Following a split-plot design arranged on a randomised complete blocks with three replications, two N forms (main plots) -urea and calcium nitrate -and four N rates (sub-plots) -50, 100, 150 and 200 kg N ha -1 -plus an un-fertilised Control, were compared. The following parameters were analysed: grain yield, N-input efficiency, grains protein concentration (GPC), total gluten, gluten fractions and minerals concentration in kernels. Calcium nitrate gave the highest yield (4.48 t ha -1 ), as predicted by the quadratic model, at 146 kg N ha -1 , on average. This was particularly noticeable in 2012, when the distribution of rainfall and temperatures regimes as well as residues' status could have favoured such N-form. These results were confirmed by the observed higher values of all indices describing N-input efficiency. High GPC values (14.8%) were predicted at slightly higher N-rates (173 kg N ha -1 , averaging both N forms). In particular, gluten proteins and glutenin/gliadin ratio accrued as the N doses increased, reaching the highest values at 150 kg N ha -1 , also positively affecting the quality of durum wheat flour. Iron and zinc concentrations were noticeably increased (38% and 37% on average) by N supply, probably due to the enhanced water use efficiency under CA systems.Principal component analysis summarised properly the obtained results: analysing the N-rates at 150 kg N ha -1 , it was confirmed that yields and quality characteristics of durum wheat were optimised in the wettest year (2011) with calcium nitrate. Moreover, the scarce amount of residues characterising the transition phase to CA, requires N application rates not lower than 150 kg ha -1 in order to ensure stable yields and important quality traits. These N rates should be modulated as the accumulation of crop residues increases over time, thanks to long-term effects of CA on soil chemical, physical and biological properties. IntroductionSouthern Europe's environment is characterised by cool and wet winters and hot and dry summers with low and erratic rainfall distribution, and by soils with very low organic matter levels and nitrogen (N) content. Nitrogen is subjected to several losses with the main pathways being represented by ammonia volatilisation, denitrification and nitrate leaching (Plaza-Bonil et al., 2014). Moreover, in these environments ...

“…On the contrary, in lower-nitrogen-input systems, limiting nitrogen resource makes it difficult to reach a sufficient grain protein concentration as required by agro-food industries either for soft wheat to make bread or for durum wheat to make semolina and pasta. Thus, in order to avoid a low durum wheat kernel vitreousness (Garrido-Lestache et al 2004) which makes it unsuitable for high-quality semolina production (Samaan et al 2006), it is necessary to increase the amounts of remobilized nitrogen into the grain during the final part of the crop cycle. Yet, as we indicated above, intercrops would be a way of improving harvested grain quality and in particular its protein concentration compared with the traditional sole cropping (e.g.…”

World population is projected to reach over nine billion by the year 2050, and ensuring food security while mitigating environmental impacts represents a major agricultural challenge. Thus, higher productivity must be reached through sustainable production by taking into account climate change, resources rarefaction like phosphorus and water, and losses of fertile lands. Enhancing crop diversity is increasingly recognized as a crucial lever for sustainable agro-ecological development. Growing legumes, a major biological nitrogen source, is also a powerful option to reduce synthetic nitrogen fertilizers use and associated fossil energy consumption. Organic farming, which does not allow the use of chemical, is also regarded as one prototype to enhance the sustainability of modern agriculture while decreasing environmental impacts. Here, we review the potential advantages of eco-functional intensification in organic farming by intercropping cereal and grain legume species sown and harvested together. Our review is based on a literature analysis reinforced with integration of an original dataset of 58 field experiments conducted since 2001 in contrasted pedo-climatic European conditions in order to generalize the findings and draw up common guidelines. The major points are that intercropping lead to: (i) higher and more stable grain yield than the mean sole crops (0.33 versus 0.27 kg m −2 ), (ii) higher cereal protein concentration than in sole crop (11.1 versus 9.8 %), (iii) higher and more stable gross margin than the mean sole crops (702 versus 577€ha −1 ) and (iv) improved use of abiotic resources according to species complementarities for light interception and use of both soil mineral nitrogen and atmospheric N 2 . Intercropping is particularly suited for low-nitrogen availability systems but further mechanistic understanding is required to propose generic crop management procedures. Also, development of this practice must be achieved with the collaboration of value chain actors such as breeders to select cultivars suited to intercropping.
