Effect of nitrogen and potassium fertilizer on herbage and oil yield of chervil plant (Anthriscus cerefolium L.)

Growth, photosynthesis, and nutrient uptake in wheat are affected by differences in nitrogen levels and forms and potassium supply

“…It has also been reported that the consequences of N metabolism 55 , N use efficiency 48 and C-N balance 56 are improved by K fertilizer application. Similarly, the results of the present study suggest that a positive synergistic interaction between K and N on assimilate production, nutrient uptake, yield formation and stress tolerance 47,57 . Thus, an understanding of the roles of the interaction between N (especially in NH 4 + ) and K in the regulation of physiological and biochemical mechanical and yield formation is required to improve sustainable productivity in wheat plants.…”

“…The interaction between K and N, especially K and N forms (both NH 4 + and NO 3 − ) on plant growth and development, has become a focus of research 4,16,17,23,47,48 . Our studies in wheat showed that N forms affect plant growth and the uptake of N and K nutrients; however, the supply level of K also has a significant influence on the regulation of plant growth, photosynthesis and nutrient absorption, with a positive interaction identified between N and K. This is consistent with earlier results of studies in wheat 49 , rice 4 , tobacco 16,17 and beans 13,14 , in which NH 4 + nutrition not only strong inhibited K uptake, but also had a marked influence on the flow and partitioning within plants, resulting in reducted water uptake and T r , apparently due to reduced g s .…”

“…These results provide evidence that assimilate partitioning in plants can be improved by changes in K supply. Some studies suggest that the controversial effects of N forms and K supply on plant growth are related to the availability of photo-assimilates for production, transportation and distribution, further indicating that K plays an important role in yield formation 23,47,48 .…”

The biosynthesis of pharmacologically active compounds in Calophyllum brasiliense seedlings is influenced by calcium and potassium under hydroponic conditions

“…In the case of Anthriscus cerefolium Hoffm. it was observed that the fertilization with K + , favored the pro- duction of biomass, the percentage of essential oils and the production of oxygenated compounds and sesquiterpenes, but not of monoterpenes (El Gendy et al 2015).…”

Potential Synergistic Action of Liquid Olive Fruit Polyphenol Extract with Aqueous Extracts of Solid Wastes of Pomegranate or/and Orange Juice Industry as Organic Phyto-protective Agents against Important Plant Pathogens - Part 1 (in vitro Studies)

“…Several physiological functions such as growth, reproduction, coloration, resistance to pathogens, and generally to plant acclimatization in a growing environment depended by the production of secondary metabolites produced by plants in very small quantities (less than 1% dry weight) [21][22][23][24][25][26][27][28][29][30][31][32][33]. The production of these secondary metabolites depends primarily on the growth phase and maturity of the plants [34,35].…”
