Special Issue Information

Dear Colleagues,

Weeds play an important role in horticultural crops, and they constitute an important cause of quantitative and qualitative worsening of yields. Moreover, most crops have a poor ability to compete with weeds. These criticalities have also increased in recent years due to the decrease in the availability of chemical herbicides and the selection of tolerant or resistant weeds. The purpose of this Special Issue is to gather information regarding the most recent research on the weed–crop relationship and recent acquisitions on management techniques. Particular interest can be reserved for the relationship between agronomic techniques (fertilization, irrigation, pest management, etc.) and weed infestation in order to develop preventive management techniques.

Some of the topics of interest of the Special Issue are listed below:

  • Role of weeds in horticultural agro-ecosystems;
  • New weed species in horticulture crops;
  • Parasitic weeds;
  • Weed–crop relationships;
  • Effects of different agronomic practices on weed infestation;
  • Chemical weed control;
  • Bioherbicides in horticultural crops;
  • Mechanical and physical weed control.

Holoparasitic broomrape weeds (Orobanche and Phelipanche spp.) are a major biotic constraint limiting the production of important food crops. Parasitism caused by Phelipanche spp. is considered to be a serious threat, particularly in the Mediterranean region. In this study, the broomrape species collected from infested fennel fields in Sid L’Mokhtar in the Central West of Morocco was described and identified morphologically and molecularly. For molecular identification, 700 bp ITS regions were PCR-amplified from two representative individuals, OA and OY-4. The obtained sequences exhibited more than 99% similarity with the P. schultzii sequence (MT026593). In addition, maximum likelihood analysis placed our species with other referred P. schultzii in the same clade. Through molecular analysis, the broomrape species attacking fennel was identified as P. schultzii. This is the first record of the broomrape species P. schultzii parasitizing fennel (Foeniculum vulgare syn. Foeniculum officinale) in Morocco. Therefore, it should be considered that this parasite could spread to other cultivated fields causing severe yield losses, requiring urgent action through efficient control measures to avoid further spread of this parasitic weed.

Italy represents the world leading producer of globe artichoke, and Puglia (Southern Italy) supplies about one-third of the nation’s production. In this research, the influence of mulching (both living mulch with subterranean clover and biodegradable mulch film) on both weed infestation and globe artichoke yield in comparison with conventional tillage was evaluated. Two globe artichoke genotypes (Capriccio—hybrid cultivar—and Brindisino—sanitized local variety) were tested in an open field located in Puglia. The following parameters were evaluated: weed infestation, yield and canopy of globe artichoke, and biomass and canopy of subterranean clover. Yield of globe artichoke (on average 16 buds plant−1) was not influenced by soil management although the total weed cover was lower by using conventional tillage. Mean canopy of T. subterraneum was higher under Brindisino (about 65%) in comparison with Capriccio (about 45%). Dry weight was higher in Brindisino (about 12 g m−2) than Capriccio (about 6 m−2) without differences among soil management treatments. Subterranean clover showed a good ability to control weed cover especially under Brindisino genotype (weed infestation always less than 1%) highlighting its particularly suitability for local varieties of globe artichoke instead of hybrid cultivars (weed infestation up to 5%). In conclusion, the results of this study suggest the positive effects of living mulch with subterranean clover for a sustainable weed management in globe artichoke as annual cropping in Puglia.

White lupine (Lupinus albus L.) is an annual legume that is grown for both seeds and green biomass, but several agronomic aspects of this crop, including response to weed competition, have not been studied extensively. Field experiments over two growing seasons (2012 and 2016) were carried out in Orestiada, Greece, to study the growth and development of spring-sown white lupine under season-long weed competition from natural weed flora compared with its growth without weed competition. Treatments were arranged in a randomized complete block design with four replications and included (i) a non-treated (weedy) control, where weeds (Chenopodium album and Sorghum halepense) remained in the plots throughout the experiments and (ii) a weed-free control, where weeds were removed upon crop emergence and the plots were kept free of weeds throughout the experiments by hand removal. The presence of Chenopodium album and Sorghum halepense reduced the aboveground dry matter accumulation of white lupine ‘Multitalia’ at 7 weeks after crop emergence by 18.0% in the first growing season and 29.5% in the second growing season, while the corresponding decrease in the aboveground dry matter accumulation at 9 weeks after crop emergence was 25.3 and 33.4%. However, the reduction in dry matter accumulation was limited to lower levels after flowering (9.9% in the first and 12.8% in the second growing season). In both growing seasons, values of the ability to withstand competition (AWC) index were lower at 7 and 9 weeks from crop emergence than at maturity. Seed yields were 1.58 Mg per ha under weedy conditions and 2.20 Mg per ha under weed free conditions in the first growing season, and 1.59 and 2.32 Mg per ha, respectively, in the second growing season. The values of the relative yield loss (RYL) index for seed yield were 28.2% in the first growing season and 31.5% in the second growing season. Overall, white lupine growth and seed yield was significantly affected by the occurrence of weeds mostly at the early vegetative stages, resulting in the potential yield not being achieved due to weed competition. Future research on weed competition across several sites and years would be useful to define more clearly the critical period of weed control in white lupine. Full article
