“…The physical barrier effect of Si was evidenced in the two experiments on plants with different nematode populations due to the increase in the rmness index of the plant tissue that received the bene cial element (Fig. 2 (E) and (F)), a fact reported by other authors (Emad et al 2017;Artyszak 2018). This silicon-promoted physical barrier makes it di cult for the stylus to penetrate, reducing the number of galls and the population and their multiplication in the roots (Silva et al 2010; Khan and Siddiqui 2020).…”

The use of silicon (Si) has a physical barrier effect on plant tissues, decreasing nematode infection in different crops. Notwithstanding, research on lettuce crop is lacking, especially regarding the chemical mechanisms of action of this bene cial element. Therefore, this study evaluates the effect of Si supply on lettuce plants infested with 0, 6000, and 12000 eggs and second stage juveniles of M. incognita, both in the absence and in the presence of Si (2 mM) in the nutrient solution. Silicon increases phenolic compounds and ascorbic acid, reducing the M. incognita population and decreasing oxidative stress. It also increases chlorophyll index and the quantum e ciency of the photosystem II (FV/FM), favoring the growth and production of lettuce plants. The use of Si decreased the number of nematodes and affected their reproduction, decreasing the number of eggs and galls in the roots of lettuce plants, being yet another sustainable alternative for the control of M. incognita. The Si bene t would be due to the combined effect of the physical barrier and the chemical action from the increase in phenolic compounds and ascorbic acid in plant tissues, improving the physiological aspects of plants. Key MessagesThe Lactuca sativa is a crop susceptible to the attack of root-knot nematode.The Si strengthens the defense system of this plant against incognita.Si has an effect on increasing the rmness of tissues acting as a physical barrier in control of incognita.Si supply decreases the reproduction rate of incognita. The Si a sustainable alternative, in control of root-knot nematode since its use can reduce applications with nematicides.

The Si benefit would be due to the combined effect of the physical barrier and the chemical action from the increase in phenolic compounds and ascorbic acid in plant tissues, improving the physiological aspects of plants.

“…What is more, the obtained results in this research are consistent with earlier reports whereas Si as individually and in mixture with other micronutrients significantly increased growth and fruit yield of okra under drought and saline soil conditions measured in terms of yield per plot and total yield per hectare (Glenn et al, 2002;Creamer et al, 2005). Moreover, increased growth and yield of musk melon (Cucumis melo L.), cucumber (Cucumis sativus L.), potato (Solanum tuberosum L.), and maize (Zea mays L.) were reported from irrigation water, soil, and foliar application of Si and mixture of B, Zn, and Si under saline and normal soil conditions (Salim, 2014;Abd-Alkarim et al, 2017) indicating that Si and the said mixture might have a positive function both in saline and non-saline soil. However, further experiment is required to understand the mechanism of the function of Si in the soils.…”

Background: Micronutrients are required in trace amounts, but are importantly associated with plant growth and development. While soil salinity causes a frequent micronutrient deficiency in soil, the condition withholds plant growth, development, and eventually crop production. Since foliar application of micronutrient provides rapid nutrient absorption compared to soil amendments, it may confer straightforward mitigation of salinity stress. However, micronutrients availability to plants under saline conditions has drawn limited attention. Objective: To study the role of four micronutrients namely boron (B), zinc (Zn), chlorine (Cl), and silicon (Si) as well as their combinations as foliar application on growth, development, and yield responses of ‘okra cv. Nulok F1’ in a naturally very slightly salinized soil. Methodology: The research site belongs to Young Meghna Estuarine Flood Plain under the soil of Agro-ecological Zones (AEZ)-18. The area of EC dsm-1 2.39 is used for the cultivation of horticultural and cereal crops. The one-factor experiment was designed in a randomized complete block design with three replications and six treatments. The factor having six different micronutrients and their combinations under saline soil viz. T1 = control (untreated), T2 = 0.2 % B as solubor®, T3 = 0.2 % ZnSO4, T4 = 0.2 % KCl, T5 = 0.2% SiO2, and T6 = 0.2% solubor® B + 0.2% ZnSO4 + 0.2% SiO2 + 0.2% KCl. Result: A number of foliar treatments of micronutrients substantially improved plant height, stem diameter, leaf number, depth of root, fruit length, number of fruits, single fruit weight, yield plot-1, and total yield. Implication: Among the treatments, Si, and a mixture of solubor® B, Zn, Cl, and Si significantly uphold growth and yield-related attributes of okra indicating them as suitable micronutrients for okra production in salt-affected areas. Conclusion: The foliar application of Si and the mixtures of the four aforementioned micronutrients might enhance the growth and yield attributes of ‘okra cv. Nulok F1’ under salinity stress.
