“…The lack of effect of the soil water tensions and potassium silicate doses, isolated or under interaction, was observed on most yield parameters. The interaction between these two factors should be important for maize plants as a result of giving resistance to water stress, as previously reported (Marques et al, 2016). The absence of significant effects of the Si dose factor (isolated) on the productive parameters of the sweet corn did not necessarily imply that it had no influence on the results.…”

“…Farmers often avoid using silicate fertilizers for fear of increasing production costs. Nevertheless, the use of fertilizers as an exogenous source of Si in sweet corn, via soil or foliage spraying, has great potential for stimulating level of resistance to water stress (Marques et al, 2016). The outcomes of the present study may encourage the use of silicate fertilization in corn plants under water stress.…”

Plant water stress is a major problem in the Cerrado biome of Brazil. Dry periods and random climatic events cause quality and yield losses in sweet corn plants. Compounds, such as silicon (Si), are being studied to reduce the negative impacts of water stress on agricultural crops. Further tests may allow farmers to increase the use of silicon-based compounds. The objective of this study was to evaluate the production parameters of the sweet corn (Zea mays var. saccharata) (Poaceae) Tropical Plus® hybrid with water stress and potassium silicate doses applied with foliar spraying. A randomized block design with four soil water tensions (15, 30, 45 and 60 kPa) and four potassium silicate doses (0, 6, 12 and 24 L ha-1) was used in a greenhouse. The studied factors, alone or in interaction with each other, did not affect most of the sweet corn yield parameters. The hypothesis that these results may have been partially affected by the presence of silicon are discussed. The sweet corn plant yield was affected mainly by the soil water tension of 60 kPa.

“…The activated Ca sensors can also bind to cis-elements of major stress-responsive gene promoters or can interact with DNA binding proteins regulating these genes, resulting in their activation or suppression [66,67]. In this context, Marques et al [68] reported a positive effect on maize production with the application of calcium silicate under water stress. Fan [33] concluded that Ca application at 10 mM achieved the highest maize yield under both normal and drought conditions while Naeem et al [29,34] found an increase in maize yield with the foliar application of Ca (40 mg L −1 ).…”

Ameliorative Effects of Calcium Sprays on Yield and Grain Nutritional Composition of Maize (Zea mays L.) Cultivars under Drought Stress

Drought stress is seriously affecting maize production. To investigate the influence of calcium (Ca) foliar application on maize production and chemical composition of grains under drought stress, two experiments were carried out at Cairo University Research Station, Giza, Egypt, during the summer seasons of 2018 and 2019. The experimental design was split-split plot design with a completely randomized blocks arrangement with three replications. Water regimes were assigned to the main plots [100 (control), 75, and 50% of estimated evapotranspiration]. Calcium levels (zero and 50 mg/L) were assigned to the sub plots. Maize cultivars (SC-P3444, Sammaz-35 and EVDT) were assigned to the sub-sub plots. Three maize cultivars were sprayed with Ca solution concentration (50 mg/L) under normal and drought conditions. The control treatment (0 mg/L) was sprayed with an equal amount of distilled water for comparison. Results indicated a significant decrease in total yield and grain characteristics [protein, ash, total sugars, nitrogen (N), phosphorus (P), potassium (K), and iron (Fe) contents] as a response of drought. Calcium foliar application significantly increased maize yield, protein, ash, carbohydrates, starch, total sugars, and ionic contents of grains, except for manganese (Mn), under all irrigation levels. Based on the drought tolerance index (DTI), only cultivar SC-P3444 showed drought tolerance while cultivars Sammaz-35 and EVDT were sensitive to drought stress. Foliar application of Ca on SC-P3444 cultivar achieved the highest grain yield per hectare (8061 kg) under the water regime of 100% of the total evapotranspiration, followed by Sammaz-35 (7570 kg), and EVDT (7191 kg) cultivars. At the water regime of 75% of estimated evapotranspiration (75% irrigation), Ca foliar application increased grain yield by 16, 13 and 14% in SC-P3444, Sammaz-35, and EVDT, respectively. At the water regime of 50% of the estimated evapotranspiration (50% irrigation), Ca foliar application increased grain yield by 17, 16, and 13% in SC-P3444, Sammaz-35, and EVDT, respectively. In brief, Ca had a clear impact on productivity and grain quality with important implications for maize yield under normal and water stress conditions. Our findings demonstrate that foliar application of Ca enabled drought stressed maize plants to survive better under stress. The most water stress tolerant cultivar was SC-P3444 followed by Sammaz-35 and EVDT under drought stress.

“…Evidence of this is the fact that plants have evolved influx, efflux and channel-type transporters to actively uptake Si ( Ma and Yamaji, 2006 , 2015 ; Trembath-Reichert et al, 2015 ; Vivancos et al, 2016 ) as well as that yield increases when plant-available Si is added to the growing medium ( Tavakkoli et al, 2011 ). The beneficial roles of Si to various plants have been the subject of extensive research and include alleviation of abiotic stresses such as drought ( Marques et al, 2016 ), metal toxicity, and micronutrient deficiency ( Hernandez-Apaolaza, 2014 ); and biotic stress from pathogens ( Winslow, 1992 ; Vivancos et al, 2015 ) and herbivores ( Reynolds et al, 2009 , 2016 ; Ye et al, 2013 ). To date, there is increasing evidence of Si priming plants for defense against herbivore attack ( Reynolds et al, 2009 ; Hartley and DeGabriel, 2016 ).…”

Silicon Supplementation Alters the Composition of Herbivore Induced Plant Volatiles and Enhances Attraction of Parasitoids to Infested Rice Plants

et al. 2017

Silicon (Si) is important in plant defenses that operate in a direct manner against herbivores, and work in rice (Oryza sativa) has established that this is mediated by the jasmonate signaling pathway. Plant defenses also operate indirectly, by the production of herbivore induced plant volatiles (HIPVs) that attract predators and parasitoids of herbivores. These indirect defenses too are mediated by the jasmonate pathway but no earlier work has demonstrated an effect of Si on HIPVs. In this study, we tested the effect of Si supplementation versus Si deprivation to rice plants on subsequent HIPV production following feeding by the important pest, rice leaffolder (Cnaphalocrocis medinalis). Gas chromatography–mass spectrometry analyses showed lower production of α-bergamotene, β-sesquiohellandrene, hexanal 2-ethyl, and cedrol from +Si herbivore-infested plants compared with -Si infested plants. These changes in plant chemistry were ecologically significant in altering the extent to which parasitoids were attracted to infested plants. Adult females of Trathala flavo-orbitalis and Microplitis mediator both exhibited greater attraction to the HIPV blend of +Si plants infested with their respective insect hosts compared to -Si infested plants. In equivalent studies using RNAi rice plants in which jasmonate perception was silenced there was no equivalent change to the HIPV blend associated with Si treatment; indicating that the effects of Si on HIPVs are modulated by the jasmonate pathway. Further, this work demonstrates that silicon alters the HIPV blend of herbivore-infested rice plants. The significance of this finding is that there are no earlier-published studies of this phenomenon in rice or any other plant species. Si treatment to crops offers scope for enhancing induced, indirect defenses and associated biological control of pests because parasitoids are more strongly attracted by the HIPVs produced by +Si plants.
