Response of Beta vulgaris L. to nitrogen and micronutrients in dry environment

Abstract

Soils in dry environments, including Egypt, have low fertility and poor structure. To enhance soil fertility and crop performance, management technologies such as plant nutrition and suitable cultivars are needed for such environments. To investigate the yield performance under such conditions, two field trials were conducted using two Beta vulgaris cultivars (Amina -V 1 ; BTS 301 -V 2 ), two nitrogen levels (N 1 -200; N 2 -350 kg N/ha) and two micronutrient mixtures (M 1 -Fe + Zn + Mn; M 2 -tap water). Results indicated that growth and yields and their qualities were positively (P ≤ 0.05 and/or P ≤ 0.01) affected by all factors singly or in various interactions. The best yield performance was obtained with the trilateral interaction application of V 2 × N 2 × M 1 . Correlation analysis revealed presence of highly significant r values between white sugar yield and root yield.

Sugar Beet Root Yield and Quality with Leaf Seasonal Dynamics in Relation to Planting Densities and Nitrogen Fertilization

“…Tsialtas and Maslaris [49] reported that N rates had no significant effect on LAI, but there was a positive reaction of LAI to N fertilization found since the higher N treatments (N120, N180, and N240) had higher LAI values than the lower rates (N0, and N60). The similar findings was reported for Mekdad and Rady [50] who found that LAI at harvest time was 4.37 dm 2 dm −2 (200 kg ha −1 N) and increased with higher nitrogen fertilization to 6.41 dm 2 dm −2 (350 kg ha −1 N). In the early growth phase, sugar beet area SLA increased because leaves have less dry matter.…”

Interactive Effects of Gibberellic Acid and Nitrogen Fertilization on the Growth, Yield, and Quality of Sugar Beet

“…The resulting increase in TSS and sucrose percentages by using the lowest nitrogen rate (165 kg/ha) in our study may be attributed to the fact that it gave the lowest root size and moisture content, therefore the concentration of TSS% and sucrose% increased. Regarding this, Abd El-Lateef et al [6], Abdelaal and Tawfik [16], and Mekdad and Rady [18] came to the same conclusion.…”

“…Mekdad [17] stated that increasing the nitrogen level to 140 kg N/fad significantly increased root length and root diameter as well as root and top fresh weight. Additionally, it whas been stated by Mekdad and Rady [18] that, except for purity percentage and harvest index, all parameters, including root length and diameter, root and top fresh weights, and root and biological yield, were significantly increased by the application of 350 kg N/ha compared to 200 kg N/ha. Moreover, it was reported that raising nitrogen levels from 69 to 92 and 115 kg N/fad significantly increased root diameter, root length, root weight, and foliage fresh weight/plant, while it significantly decreased total soluble solid (TSS), sucrose, and purity percentages [19].…”

The influence of foliar fertilization with nitrogen, sulphur, amino acids and microelements on spring wheat

“…Today, fertilizer manufacturing industry is highly specialised and advanced in this particular field and the range of foliar fertilizers manufactured is very broad. Positive influence of foliar fertilization with the recommended nutrients and biostimulants -N, S, amino acids and microelements on plant physiology was proved (Kalajia et al, 2014;Skwierawska et al, 2016) and was done field experiments with different plants (Brar, Kaur, 2006;Staugaitis, Petrauskienė, 2006;Peng et al, 2013;Mekdad, Rady, 2016). However, when applying foliar fertilization, soil and its agrochemical properties should be considered.…”

“…Fertilization through leaves with amino acids, microelements and sulphur influences plants favourably and increases the productivity of spring barley (Staugaitis, Petrauskienė, 2006;Pranckietienė et al, 2015), sugar beet (Mekdad, Rady, 2016), potatoes (Brar, Kaur, 2006), maize (Peng et al, 2013) and vegetables (Bundinienė et al, 2007). The experiments indicated that the productivity of spring wheat was increased by foliar fertilization with nitrogen, potassium and zinc fertilizers (Guenis et al, 2003;Zafar et al, 2016).…”
