Effect of Nitrogen Fertilization and Foliar Application with Iron Plus Molybdenum on Quality Parameters and Chemical Composition of Jews Mallow Plant (Corchorus olitorius L.)

AbstractThe effect of marine calcite, a mixture of ortho- and polysilicic acid as well as orthosilicic acid applied as a foliar spray on the chemical composition of sugar beet leaves in the critical phase of nutrient supply (beginning of July) but also leaves and roots during harvest time in 2015–2016, was studied. The content of silicon in the leaves ranged from 1.24 to 2.36 g kg−1 d.m. at the beginning of July, 3.85–5.34 g kg−1 d.m. during harvest and 2.91–4.20 g kg−1 d.m. in the roots. The foliar application of silicon caused a significant increase in the content of magnesium and calcium in leaves (in July) as compared to the control. The sugar beet consumes approx. 75 kg Si ha−1, which is almost 3.5 times more than P and 20% more than Mg thus proving its importance for its species. About 70% of the silicon taken up by sugar beet is stored in roots and 30% in leaves. The pure sugar yield is most favorably influenced by two- and threefold foliar application of the product containing silicon in the form of orthosilicic acid stabilized with choline, and a threefold mixture of ortho- and polysilicic acid. The increase in the pure sugar yield is not the result of a change in the chemical composition of sugar beet plants, but their more efficient functioning after foliar application of silicon under stress conditions caused by water shortage.

Increasing rates of field nitrogen (N) application (0, 100, 200, 300, 400 and 500 kg N ha−1) resulted in markedly higher yields of winter white cabbage (Brassica oleracea L. var. capitata 'Bartolo') due to larger head size. Glucose and fructose contents increased with increased nitrogen. In contrast, ascorbic acid and sucrose contents declined slightly with increased nitrogen. Nitrogen rate had little effect on storage losses. The results indicated that increased N fertilization provided overall benefit to cabbage production.

Scientific Agriculture

A field experiment was conducted during two seasons 2018/2019 and 2019/2020 at Homs Agriculture Research Center, General Commission for Scientific Agriculture Researches (GCSAR), Syria, to study the effect of nitrogen fertilization rates and foliar application of boron on root yield and quality and dry matter yield of fodder beet. Results showed that the effect of nitrogen fertilization was significant (p≤0.001) for all studied traits except brix%. The effects were significant positive on root, shoot and biological yields, sucrose percentage, root, shoot and total dry matter yields. On the other hand the effect of boron spraying was presented for each season separately, because the differences of boron treatments were significant for all parameters except brix% at each season, and HI at the two seasons, while the differences of years were significant for all parameters except for HI. the highest yield and yield components were achieved by adding 300 kg N/ha with the addition of boron under Homs governorate conditions.

The Impact

The long lifecycle, also known as durability and the permanence / invariability in the quality of papers and cardbords for graphic art, are today the basic requirements, imposed by printed art in terms of high quality parameters. These two factors are a manifestation, depending on different internal chemical-composition properties of the paper consistency and external influences of the ambience. Longevity and permanence are perceived as a function of aging and are actually observed at a later point in time. It is important to clarify that they are terms with different contents where „durability” is perceived as the ability of the paper or cardboard to resist the impact of wear during use, and the „permanence” is the possibility of product to remain chemically and physically stable for a long period of time.

Yield And Quality

The objective of the current study was to investigate the effect of soil and foliar application of some fertilizers on the yield and quality of table grapes cv. Alkdarri. Soil and foliar fertilizer application treatments included a control, Ca 200 g/vine, K 150 g/vine, N 200 g/vine, Ca 30 g/L, grow more INC fertilizer 10 g/L, K 20 g/L, and Cu 5 mg/L. Results indicate that soil and foliar fertilizer application increases quality and quantity of table grapes compared to control treatment. The highest berry diameter, a weight of 100 berries and a size of 100 berries were obtained in vines treated with Ca 200 g/vine, using the soil application method. The highest cluster weight was obtained in vines that were treated with K 150 g/vine, using the soil application method. The highest berry firmness was obtained in vines that were treated with K 20 g/L using the foliar application method. The highest pH and TSS were obtained in vines treated with Cu 5 mg/L, using the foliar application method. The highest fruit yield was found in vines that were treated with 150 g K.
