Early and Total Yield Enhancement of the Globe Artichoke Using an Ecofriendly Seaweed Extract-Based Biostimulant and PK Fertilizer

Abstract

This study evaluated the effect of phosphorus and potassium (PK) fertilizer levels and foliar seaweed extract on early and total yield productivity and the growth of globe artichoke plants. Field experiments were conducted over two seasons on loamy–clay soil at the vegetable research farm, of the Faculty of Agriculture, Alexandria University, Egypt. Fertilizer levels of 0, 25, 50 and 75 mL L−1, and seaweed extract concentrations of 0, 5 and 10 mg L−1, individually and in combination, were used. Globe artichoke plants treated with PK liquid fertilizer, with and without seaweed extract, showed critical increases in growth (plant height and number of leaves per plant as well as foliage dry weight), yield, and some chemical constituents compared to untreated plants. The PK3 fertilizer level and 10 mL L−1 seaweed extract as a foliar spray showed greater effects than other combinations.

Rationalization of Water Use and Fertilization of Globe Artichoke Using Magnetic Water Irrigation

“…Fertilizing globe artichoke plants with 75% of the recommended NPK provided the highest values of plant height in both seasons. Similar findings from Selim (2019) demonstrated that adding 75% NPK significantly enhanced the height of potato plants and (Elsharkawy et al, 2021) who found that treated artichoke with 75% of requisite P and K increased the plant height. On the contrary, (Petropoulos et al 2022) found that the maximum plant height was produced with adding 100% of recommended potassium for globe artichoke plants.…”

“…K is essential for sugar translocation and the synthesis of carbohydrates because potassium ion is known to be one of the three largest constituents in sieve tube sap (Moussa, 2011). Increasing rates of potassium and phosphorus fertilizers had positive effect on the inulin content of artichoke heads (Elsharkawy et al,2021). Related results were obtained by (Petropoulos et al, 2022) who indicate that applied 75% of recommended dose K significantly increased the inulin content.…”

Trends in scientific literature on the environmental sustainability of the artichoke (Cynara cardunculus L. spp.) supply chain

“…Several authors have investigated alternative and innovative crop management strategies to increase the globe artichoke yield productivity, by adopting different fertilization rates (Ierna et al. , 2012a, 2012b), using biostimulant (Elsharkawy et al. , 2021) and organo-mineral (Ierna and Mauromicale, 2013), caring the seasonality (Ierna et al.…”

Improving the Growth and Yield of Potato Plants in the Winter Season

“…i.e., auxins (IAA and IBA), cytokinins, vitamins, enzymes and amino acids (Khan et al, 2009). Stress resistance has been demonstrated to be improved by using seaweed extracts and improving yield in many other crops, such as Celeriac Plant (Shehata et al, 2011) common bean, (Zewail, 2014), spinach (Xu and Leskovar, 2015), also, in this regard, plants sprayed with algae extract enhanced growth characters, e.g., plant height, numbers of leaves, leaves area, fresh and dry weight of shoot, yield and its components on Globe Artichoke (Sayed et al, 2018;Madian et al,2020;Elsharkawy., et al, 2021), on sweet potato (Helaly, 2021), on tomato (Hussain et al, 2021), on potato (Negm et al, 2021).…”
