Elytrigia Repens

Quackgrass [Elytrigia repens (L.) Beauv.] is a primary noxious weed, but some cattle producers are discovering its value as forage for early-season grazing and for winter feeding as hay. Little information is available on how its production and quality change with advancing maturity and on its response to improved management in the Parkland zone of the Canadian prairies. The objective of this study was to determine the effects of harvest date and N fertilizer (surface-broadcast ammonium nitrate at 0, 56, 112 and 168 kg N ha-1) on the forage yield and quality of quackgrass. The study was done on a 10-yr-old quackgrass (˜ 90%) dominated stand on a silty clay loam (Dark Gray Luvisol) soil near Tisdale in northeastern Saskatchewan. For the harvest dates between early June and early September, maximum dry matter yield (DMY) was in August and maximum protein yield (PY) occurred in July. A delay in harvest reduced protein concentration (PC) and total digestible nutrients concentration (TDN), while it increased acid detergent fiber concentration (ADF). The DMY, PC and PY increased with increasing N rate for both Cut 1 (in early July) and Cut 2 (in late September). Strong quadratic relationships were observed between DMY and N rate. The effect of N application was relatively greater on PY than DMY due to the cumulative effect of increases in DMY and PC, and was greater in Cut 1 than in Cut 2. With the increase in N rate, TDN showed a trend of small increase, while ADF tended to decrease. In summary, the results show that N fertilization increases both forage yield and quality of quackgrass. Harvesting in late July or August is likely to provide maximum DMY when one harvest per season is taken.

Calcium Phosphate Nanoparticles

In recent years, the application of nanotechnology for the development of new “smart fertilizers” is regarded as one of the most promising solutions for boosting a more sustainable and modern grapevine cultivation. Despite showing interesting potential benefits over conventional fertilization practices, the use of nanofertilizers in viticulture is still underexplored. In this work, we investigated the effectiveness of non-toxic calcium phosphate nanoparticles (Ca3(PO4)2∙nH2O) doped with urea (U-ACP) as a nitrogen source for grapevine fertilization. Plant tests were performed for two years (2019–2020) on potted adult Pinot gris cv. vines grown under semi-controlled conditions. Four fertilization treatments were compared: N1: commercial granular fertilization (45 kg N ha−1); N2: U-ACP applied in fertigation (36 kg N ha−1); N3: foliar application of U-ACP (36 kg N ha−1); C: control, receiving no N fertilization. Plant nitrogen status (SPAD), yield parameters as well as those of berry quality were analyzed. Results here presented clearly show the capability of vine plants to recognize and use the nitrogen supplied with U-ACP nanoparticles either when applied foliarly or to the soil. Moreover, all of the quali–quantitative parameters measured in vine plants fed with nanoparticles were perfectly comparable to those of plants grown in conventional condition, despite the restrained dosage of nitrogen applied with the nanoparticles. Therefore, these results provide both clear evidence of the efficacy of U-ACP nanoparticles as a nitrogen source and the basis for the development of alternative nitrogen fertilization strategies, optimizing the dosage/benefit ratio and being particularly interesting in a context of a more sustainable and modern viticulture.
