“…Sanchez et al [30] reporting on organic high tunnel cucumber production on evaluating the properties of mulches to reduce weeds, discovered yields were not affected by mulch treatment, thus depicted weed populations stayed below yield-depressing volumes despite treatment. A study by Ferrara et al [31] on effects of mulch on soil and performance of grapevines in southeastern Italy reported that yield and constituent components of grapes were not affected by organic and synthetic mulches in contrast to weed mowing. Contrasting results were reported by Laurie et al [19], where studies showed newspaper mulch and narrow spacing resulted in high marketable sweetpotato root yield, such as hand weeding.…”

Mulch Treatment Effect on Weed Biomass and Yields of Organic Sweetpotato Cultivars

2019

Weeds are a challenge, particularly in organic agriculture, due to restrictions on the application of synthetic herbicides and chemicals. A preliminary cultivar evaluation trial of organic sweetpotato was conducted in 2015 at Tennessee State University certified organic farm. Three mulches: wheat straw, pine needle, and black plastic mulch, along with a control (no mulch), were evaluated for their weed management abilities in a sweetpotato field. Four cultivars of sweetpotato were planted in 0.91 m wide mulch beds with 0.3 m row spacing anddrip irrigated with four replications. Data was collected during the growing season on the dry weight of weeds that emerged in a quadrat and yield components at harvest. Results of two-way ANOVA revealed that mulch treatments affected the weed biomass, weed density, and cull yields. Though the use of mulches had no significant effect on other yield components of sweetpotato in this study; it was beneficial for weed management.

“…It can be considered a standard variety for seeded grapes because of many years of cultivation in the area. In these table grape vineyards, rock fragmentation is a common practice adopted before planting the vines in order to improve the available soil for the roots ( Ferrara et al, 2012a ), and recently mulching (with leguminous species) has also become common to improve the contents of both N and organic matter in the soil ( Ferrara et al, 2012b ; Torres et al, 2017 ). To our knowledge, N concentration in the table grape varieties cultivated in Puglia and the amount accumulated by the vines during the season have never been investigated.…”

Nitrogen Distribution in Annual Growth of ‘Italia’ Table Grape Vines

Little information is available about nitrogen (N) content and its concentration in table grape vines. Knowledge of the quantity of N accumulated by the vine organs during the season could support sustainable fertilization programs for table grape vineyards. The aim of the present study was to determine the N content and its concentration in different annual organs, including summer and winter pruning materials, clusters at harvest, and fallen leaves at post-harvest. Specifically, biomass and N were analyzed at six phenological growth stages (flowering, berry-set, berry growth, veraison, ripening, and harvest) from 2012 to 2015. Nitrogen concentration was highest (>40 g/kg d.w.) in the leaves of the secondary shoots at flowering, whereas values >30 g/kg were measured in the leaves of the primary shoots. Nitrogen concentration in the clusters at harvest was 5.3–7.6 g/kg with an accumulation of 18.6–25.4 g/vine in the seasons. The decrease of N content in the primary leaves after flowering indicated a remobilization toward the clusters, which acted as a stronger sink. Later in the season (veraison-ripening), leaves translocated N to permanent organs and primary stems. Pruned wood and fallen leaves accounted for the largest N removal from the vine after clusters, 6.0–7.9 and 9.2–10.2 g/vine, respectively. With regard of the vine annual biomass, the growth followed a sigmoidal model reaching 7300–7500 g of d.w./vine at harvest. Vine leaf area, including both primary and secondary leaves, peaked at veraison (17–21 m2). Vines accumulated ≅35 g/vine of N at harvest, not considering the N removed with the intense summer pruning practices (≅7 g/vine) and the fraction mobilized toward the storage organs (10–15 g/vine). The overall N required by the vine was around 50–55 g/vine, which corresponded to ≅80 kg of N/ha in a vineyard with 1500 vines and a yield of 40 t/ha. Summer and winter pruning practices removed 29–31 g/vine of N which will be partly available (to be considered in the fertilization schedule) for the vine in the successive years if pruned residues were incorporated and mineralized in the soil.

“…In terms of soil management, application of living mulch versus organic mulch in the vine rows may also have a positive effect on skin colour, because it reduces vine vigour, that is, assimilation rate and stomatal conductance (Ferrara et al. ). With regard to the phenological stage, sugar, in particular sucrose, is known to be an activator of gene expression of enzymes involved in anthocyanin biosynthesis (Hiratsuka et al.…”

Background and Aims:In some years, the table grape cultivar Crimson Seedless does not reach the commercially acceptable level of red colour in Mediterranean climates, with negative consequences for the grower. Application of abscisic acid (S-ABA) and sucrose could be a tool for overcoming this problem. Methods and Results: A commercial formulation of S-ABA (400 mg/L) and sucrose (10%) was applied to Crimson Seedless at the beginning of veraison and 5 days later in order to verify the effect on harvestable bunches, skin colour, chemical characteristics, anthocyanin content, antioxidant activity and S-ABA concentration either in the skin or the pulp of the berry. The application of S-ABA and sucrose improved the colour of the berries and increased the amount of harvestable bunches at the first pick (80-95%) compared with that of the control treatment (43%). Ripening attributes (total soluble solids, pH, titratable acidity) were not affected by the application of either S-ABA or sucrose. The S-ABA concentration in skin and pulp increased significantly after the treatments and at first harvest. Abscisic acid increased the concentration of anthocyanins and showed a positive effect on the antioxidant activity. Conclusion: Abscisic acid and sucrose improved the colour of the berry skin, with improved results obtained when S-ABA was applied alone and at the beginning of veraison. Sucrose, although to a less extent, was also effective in improving skin colour and increasing the number of harvestable bunches at the first pick. Significance of the Study: This study provides new information about the positive effect of either S-ABA or sucrose on colour, anthocyanin concentration and antioxidant activity of the berry. Moreover, bunches could be harvested in fewer picks with important economic consequences for the grower and with an S-ABA concentration in the berry within the physiological values.
