Effect of some Potassium Sources on Productivity and Quality of Pea under Conditions of Saline Soil

Abstract

This study was carried out during 2015 and 2016 seasons at a private Farm in Road Village in Sahl El-Husseiniya, Sharkia Governorate to study the influence of foliar spraying with three potassium sources at three concentrations from each of them i.e. potassium sulfate1,2 and 4 g/ L; potassium silicate at 1,2,and 4cm/L as well as potassium humate at 1,2 and 4 cm / L beside without foliar spraying (control) to reduce the bad effects salinity stress on growth, yield and quality of pea Master B cultivar under saline soil conditions. The experiment was carried out by using completely randomized blocks design with three replications. Spraying pea plants with potassium silicate (4 cm/L) significantly increased and created the maximum means of all studied traits (growth, yield and yield attributes and chemical constituents in the leaves and seeds) as compared to other studied treatment in the two seasons. Spraying with potassium silicate (2 cm/L) was the second best treatment, followed by potassium silicate at the rate of 1 cm/L, then potassium humate at the rate of 4 cm/L and 2 cm/L in the two seasons. Conversely, the lowest means of these traits resulted from control treatment in the two seasons. Overall, using potassium silicate at different rates as foliar application exceeded using potassium humate at different rates exceeded potassium sulfate at different rates in the two seasons. Concerning proline % in leaves, it had adverse trend comparing with other studied traits in the two seasons. Generally, it could be recommended that spraying pea plants through 4 cm potassium silicate/L to enhance growth, yield and yield components and chemical constituents of pea under the environmental conditions of same research.

Effect of Organic, Chemical Fertilizations and Plant Stimulants on Eggplant (Solanum melongea L.) Yield and Quality under Conditions of Saline Soil

“…The enhancing effect of potassium silicate may be due to using SiO could be attributed to the benefit effects of Si in the plant, as an improve of the architecture for showing more erect leaves, which intercept higher solar luminosity increasing the photosynthetic efficiency and higher chlorophyll content.These results are in the same line of those obtained by Braga et al(2009), El-Hedek(2013) and Ismail et al(2017).…”

“…El-Hedek (2013) also found that spraying potassium silicate on leaves led to a significant improvement in the components of the wheat crop and an increase in its content of potassium, calcium and phosphorous ratios. In addition, Ismail et al (2017) found that spraying of pea plants with potassium silicatee at a rate of 4 cm / liter resulted in a significant increase and produced the uppermost average values for all studied vegetal growth parameters and their chemical components and components in leaves and seeds. Spraying of yeast has been found to increase the growth, productivity and quality of many vegetable crops (Abu Al-Nasr et al 2001;Kapil et al 2005 andFawzi, 2007).…”

Influence of Potassium Humate and Micronutrients Foliar Nutrition on Sesame Productivity and Quality under Alluvial Soils of Nile Delta

“…The beneficial impact of KH on the leaves photosynthetic pigments could be explained on the basis of that humic substances can directly or indirectly affect the physiological process of plant growth by promoting the uptake of macro-and micronutrients , affecting the biochemical substances , carrying nutrients and growth regulators and acting as hormones like substances (Verlindern et al, 2009). Yet , Ismail et al, (2017) and Dawood et al,(2019) attributed the enhancement effect of KH to the beneficial function of potassium on osmoregulation photosynthesis , transpiration, and translating of assimilates into sink organs . As a result, growth characteristics improve (Vani et al, 2017) .…”

Alleviation of Water Deficiency Effect by Application of Potassium Silicate to Faba Bean Intercropped With Sugar Beet in Sandy Soil

“…Arkadiusz (2018) reported that spraying with 100 ppm to 300 ppm of potassium silicate in the growing medium had high effect at 4-leaf stage and positively effect at other stages of plant. Application of foliar spraying of pea plants with K-silicate at the rate of 228 ppm enhanced growth parameters, yield and yield components and nutrients contents (Ismail et al, 2017). Moustafa (2013) found that single and combined application of Ksilicate at 0.05 to 0.20% and royaljelly at 0.025 to 0.10%, greatly enhanced growth characters, pigments content and leaf content of N, P and K. Furthermore, Abdul-Qadir et al (2017) showed that when plants were treated with K-silicate, marked improvement in each of shoot fresh weight, shoot length, leaf area and leaf length was observed under water stress.…”
