<p style="text-align: justify;"><strong>Aims</strong>: To study the impact of soil-type, grapevine variety and rootstock on grape yield and wine quality in prestigious estates located in the Bordeaux area (France).</p><p style="text-align: justify;"><strong>Methods and results</strong>: High-resolution soil maps (scale: 1/3000<sup>th</sup>) were created for seven prestigious red wine-producing estates in Bordeaux, covering a total area of approximately 400 ha. Soil-type, rootstocks and grapevine varieties were recorded for each vineyard block. A Quality Index was created by considering the destination of the grapes produced in each block, whether they were integrated in the first, the second or the third quality wine produced by the estate. Quality Index was averaged over five vintages. Yield was also measured for each vineyard block and averaged over five vintages. PEYROSOL (gravelly soil) was the most frequent soiltype in these estates (45% of the total mapped area). Soils with temporary waterlogging (REDOXISOL), heavy clay soils (PLANOSOL) and sandygravelly soils (BRUNISOL) covered around 10% of the mapped area each. Highest quality was obtained on PLANOSOLS, ARENOSOLS (sandy soils), BRUNISOLS and PEYROSOLS. Quality was low on COLLUVIOSOLS (deep soils on colluvium), LUVISOLS (leached acidic soils) and REDUCTISOLS (soils with permanent waterlogging). Cabernet- Sauvignon was the dominant grapevine variety (59% of the mapped area), followed by Merlot (32%), Cabernet franc (8%) and Petit Verdot (1%). On average, the Quality Index was higher for Cabernet-Sauvignon and Merlot compared with Cabernet franc and Petit Verdot. Riparia Gloire de Montpellier (RGM) was by far the most used rootstock. It covered 45% of the mapped area. Including 3309C and 420A, these three rootstocks covered 75% of the total acreage planted in these estates. Highest quality wine was produced with 420A, RGM, 3309C and Gravesac. Highest yields were obtained with 161-49C, 101-14 MG, RGM, SO4 and 420A.</p><p style="text-align: justify;"><strong>Conclusions</strong>: Soil, grapevine variety and rootstock have a major impact on yield and wine quality in prestigious Bordeaux wine producing estates.</p><p style="text-align: justify;"><strong>Significance and impact of the study</strong>: Assessment of a Quality Index by soil-type, cultivar and rootstock can indicate which combinations of soiltype, cultivar and rootstock would best optimise quality performance in Bordeaux vineyards.</p>

Tropospheric ozone (O3) is widely recognized as the cause of substantial yield and quality reduction in crops. Most of the previous studies focused on the exposure of wheat cultivars to elevated O3 levels. Our main objectives were to: (i) investigate the consistency of wheat cultivars’ physiological responses across two different realistic O3 levels; and (ii) compare these physiological responses with those under short acute O3 exposure. Three commercially available hard spring wheat cultivars bred under semiarid and Eastern Mediterranean conditions were exposed to two different O3 levels during two consecutive seasons (2016–2018)—36 and 71 ppbv 7 h mean O3 mixing ratios in open-top chambers. The results were compared to those following short acute O3 exposure (102.8 ppbv, 7 h mean for 10 days) in a greenhouse. Non-stomatal responses were significantly more pronounced than stomatal responses in all cultivars under different levels of O3. The specific cultivar was observed as the most O3-tolerant under all experiments. The fact that the same cultivar was found remarkably tolerant to the local semiarid ambient conditions according to other studies and to O3 exposure based on the present study supports a link between cultivar resistance to drought conditions and O3.

The cultivation of perennial grasses is one of the most desirable alternatives as energy feedstock, but it is difficult to achieve competitive yields under Mediterranean marginal conditions. The aim of this study was to assess the performance of three cool-season grasses (Agropyron spp.) from an agronomic and energetic point of view by comparing the dry matter (DM) yields, rain use efficiency, chemical composition, and biomass quality over an eight-year period in Spain under marginal rainfed conditions. The tall wheatgrass (Agropyron elongatum (Host) Beauv.) cultivars, Alkar (4.8 Mg DM·ha−1) and Jose (4.7 Mg DM·ha−1), achieved the highest yields. Productions below 0.5 Mg DM·ha−1 were obtained when rainfall was lower than 150 mm between March and June. The biomass obtained from the tested grasses showed relatively high contents of ash, silicon, and alkali elements. Net calorific values ranged between 16.7 and 18.5 MJ·kg−1 db. Differences in the composition among species and cultivars are not likely to affect their combustion behavior from a practical point of view. The ash content, as well as the concentrations of K, S, Na, and Cl, tended to decrease over the years. The results offered would be very useful for the implementation of this type of crop in marginal land.

Towards the strive of developing sustainable freight transport networks in Europe, the EU and the developing South-Eastern Europe in particular, this paper initially examines the feasibility of establishing a navigable link along the Axios–Morava waterway, for freight transport between the Eastern Mediterranean Sea (via the Aegean) and the Danube River, and then proceeds with its energy and air quality comparison with the competing modes of rail and road. It was found that this waterway service is technically feasible and offers an energy and carbon efficient alternative to road-borne and rail-borne freight. However, the land-based services were found to be superior with regard to their impact upon the air quality of the region, mainly attributed to the stricter emission standards applicable to these transport modes. Finally, it is proposed to build on the ongoing international policy and funding interest in this project in order to implement all the necessary infrastructural and operational changes which will make the proposed waterway service a commercially and environmentally sustainable freight transport alternative in South-Eastern Europe.

The tomato industry has been searching for new genotypes with improved fruit production, both in the field and industrially processed, together with high-quality performance under sustainable management conditions. This research was carried out in Southern Italy with the aim of assessing the effects of industrial processing on the yield and quality of four tomato hybrids grown according to organic farming methods and addressed at dicing. MAX 14111 and HMX 4228 showed the highest values of field and processing yield as well as reduced sugars and fructose. MAX 14111 had the highest values of total solids and soluble solids, titratable acidity, fiber, energetic value, polyphenols, and also rutin, though not significantly different from Impact. HMX 4228 performed best in terms of sugar ratio, color and naringenin. Concerning the diced products, the sensorial qualities of the four hybrids differed significantly. Total polyphenols, naringenin and rutin in the tomato fruits were higher in the processed than in the raw product. The appreciable fruit yield and quality resulting from both field and processing phase represent a promising perspective for identifying improved tomato genotypes addressed at dicing.

Variety trials were conducted in 2010 and 2011 to evaluate the yield and quality performance of 11 open pollinated and three hybrid tomato (Solarium lycopersicum L.) cultivars grown organically in Lajas, Puerto Rico. In both years, significant differences in marketable fruit yield were observed. Yields in 2010 ranged from 72.1 Mg/ha for 'Roma' to 8.6 Mg/ha for 'Marion'. 'Roma' and 'Neptune' (65.6 Mg/ha) were among the highest yielding cultivars. In 2011, significant yield differences were also observed. Marketable fruit yield ranged from 54.7 Mg/ha for 'Early Girl' to 23.5 Mg/ha for 'Super Sioux'. 'Early Girl', 'Flora Dade' (53.8 Mg/ha), 'BHN 444' (50.8 Mg/ha), 'Roma' (48.6 Mg/ha), 'Eva Purple Ball' (48.4 Mg/ha), 'Traveler 76' (46.4 Mg/ha) and 'Celebrity' (45.9 Mg/ha) were among the highest yielders. 'Early Girl' was consistently among the top cultivars in both seasons for taste, yield, and fruit appearance. Open pollinated cultivars performed with more variability between the two seasons than the hybrids. The open pollinated cultivars which ranked highest during the two-year study for taste, yield, and overall appearance were 'Roma', 'Homestead 24', 'Ozark Pink', and 'Traveler 76'. This study indicates that tomato can be grown successfully under an organic management system in Puerto Rico using either open pollinated cultivars or hybrids.

A field experiment conducted during Rabi season of 2017-18 at wheat research farm of CCS Haryana Agricultural University, Hisar, India to study the effect of sowing dates and varieties on yield and quality performance of wheat (Triticum aestivum L.). The experiment was laid out in split plot design with three replications containing four sowing dates viz. 5th November, 25th November, 15th December and 5th January as main plot treatments and seven wheat varieties i.e. HS 562, HD 2967, HD 3086, HI 1544, MACS 6222, WR 544 and WH 1105 as sub plot treatments. On the basis of one year study it was concluded that among sowing dates, 5th November sowing is the most economical and suitable than rest of the sowing dates. 5th November sown crop recorded significantly longer spike (11.7 cm), higher number of effective tillers (98.3 per mrl), grains per spike (48.6), test weight (39.9 g), grain appearance score (8.3), hectoliter weight (82.9 kg/hl), grain yield (5432 kg ha-1) and harvest index (39.0%) compared to rest of the sowing dates, while highest protein content (12.9 %) was observed with 5th January sown crop. Maximum net return (Rs.54, 262 ha-1) and B: C (1.73) were recorded with 5th November sowing. Among the varieties, HI 1544 recorded significantly higher number of effective tillers (94.6 per mrl), grains per spike (48.4), test weight (38.6 g), grain yield (4920 kg ha-1) harvest index (39.2), grain appearance score (8.1) and hectoliter weight (82.0 kg/hl), while variety WH 1105 resulted in longer spike (11.5 cm) and WR 544 in higher protein content (12.6 %) as compared to rest of the varieties. While comparing the interaction of varieties with date of sowing, HI 1544 produced significantly higher grain higher yield (6007 kg ha-1) of wheat sown at 5th November which was statistically at par with WH 1105 (5833 kg ha-1) and HD 3086 (5616 kg ha-1) at same date of sowing. Delayed sowing of HI 1544 from 5th November to 25th November reduced the grain yield by 9.1 per cent; to 15th of December by 21.0 per cent and to 5th January by 42.3 per cent.
