Effect of Irrigation Intervals and Foliar Applications with some Nano-Fertilizers on Growth and Productivity of Globe Artichoke Plant: B-Yield and its quality

Abstract

Two field experiments were conducted during the seasons of 2017-2018 and 2018-2019 at Baramoon Research Station, Mansoura, Dakahlia Governorate, Egypt, to study the effect of irrigation intervals and foliar application with nano-potassium and boron fertilizers under mineral potassium fertilization on productivity and quality of globe artichoke French Hyrious variety. The experiment divided into 36 treatments, representing the combinations of three irrigation intervals (10, 20 and 30 days) as vertical-plot, three rates of potassium fertilization (50, 75 and 100%) as horizontal plot and four foliar application rates of Nano-fertilizers (without, 3000 ppm K, 50 ppm B and 3000 ppm nano-K + 50 ppm nano-B) as split plot. The design of the experiment was a strip-split plot with three replicates. The results indicated that the fertilization of globe artichoke plants with potassium at 100% (200 kg/fed. potassium sulfate.) or 75% (150 kg/fed. potassium sulfate.) with foliar application by a mixture of 3000 ppm nano-K+ 50 ppm nano-B treatment and irrigation every 20 days to obtain the best yield (early and total) parameters and the highest quality. Therefore, we recommend this treatment because it saves in the amount of potassium and the amount of irrigation water and thus reduces the costs of artichokes production and environmental pollution under the conditions of this study.

The investigation of agricultural status of registered functional plant artichoke (Cynara cardunculus var. scolymus L.) of Hasanağa region plantations in Bursa province

“…K, enginarda su ve gaz alışverişini düzenler, erkenciliği arttırarak ürün kalitesini iyileştirmektedir (Saleh et al, 2016). K'un enginarda bitki boyu, ana baş ağırlığı, bitkide baş oluşumu, baş sayısını artırdığını bildirilmiştir (Rincón et al, 2007;Saleh et al, 2016;Anwar et al, 2017;Öztürk vd., 2020;Tartoura et al, 2021;Petropoulos et al, 2022). K alımı kış aylarında neredeyse 40 gün durur ve büyümenin sonraki aşamasında hemen ve dikkat çekici bir şekilde yeniden başlar.…”

“…Yapılan başka araştırmalar (Shaheen et al, 2007;Colla et al, 2012;Rocchetti et al, 2020) bu sonucu desteklemektedir. Bazı araştırmalarda (Ierna et al, 2012;Öztürk vd., 2020;Tartoura et al, 2021;Petropoulos et al, 2022) ise K/N oranının birden düşük olduğu belirlenmiştir. Nitekim bu araştırmalar enginarda K takviyesine yönelik araştırmalardır (Çizelge 8).…”

“…Bu uzun sapların hem uçlarında hem de dallarında yenilebilir başlar oluşur. Bitkinin yenilebilir kısmı; büyütülmüş hazne ve olgunlaşmamış çiçek salkımının iç kısımları olan baş ve kalınlaşmış brakte yaprak tabanlarıdır (Tartoura et al, 2021). Bu bölüm "çiçek tablası", "baş" veya "kapitulum" olarak çeşitli şekillerde tanımlanır (Lombardo et al, 2017).…”

Effect of Water Deficit, Organic Fertilization and Some Soil Additions on Potato Productivity

“…led to a significant increase of leaves number, plant height, foliage fresh weight/plant and number of main stem in addition to N, P, K, chlorophyll a and chlorophyll b content in the leaves, as well as tubers weight and number per plant, marketable and total yield as well as, vitamin C, TSS, N, P and K content in tubers. Also, Tartoura et al (2021) on artichoke, showed that the mean values of number of heads and heads weight for early and total yield per fed. significantly increased when the plants irrigated with all intervals (10, 20 and 30 days).…”
