Ghaf, a resilient tree in arid environments, plays a pivotal role in ecological restoration, desertification mitigation, and cultural heritage preservation. However, the seeds' inherent challenges, notably their hard outer coating restricting germination, emphasize the pressing need for innovative strategies. This work aimed to investigate the optimization of Ghaf seed germination process through seed priming with ZnO nanoparticles treatment (duration (t), concentration (c), temperature (T) and agitation (a), employing the Taguchi method for efficient experimental design. Notably, it revealed that concentration is a pivotal influencer in the optimization of Ghaf seed. The results showed that the concentration of ZnO nanoparticles has no linear relation with any other parameters. To verify the outcomes, validation tests were performed utilizing the predicted optimal parameters. The observed low error ratio, falling within the range of 1–6%, confirmed the success of the Taguchi methodology in identifying optimal levels of the factors chosen. Significantly, ZnO-primed seeds showcased a remarkable enhancement in Ghaf seed germination, increasing from 15–88%. This study introduces a novel approach utilizing ZnO nanoparticle treatment optimized through the Taguchi method, significantly enhancing seed germination rates of Ghaf seeds and offering a promising avenue for sustainable agricultural practices in arid environments.

“…Stefanescu (2015) studied the influence of solidification factors such as normal chemical composition, magnesium treatment and inoculation, which control the shape of the cooling curve. Santhosh and Lakshmanan (2016) found that inoculation and CE are the most significant parameters affecting the quality of ductile iron casting and suggested 0.8 Wt.% inoculation is optimum.…”

Purpose The final properties of ductile iron are decided by the inoculant processing while pouring the melt. The shape and size of nodules generated during solidification are of paramount importance in solidification of ductile cast iron. The purpose of this study is to examine the effect of different inoculant addition on the solidification of ductile cast iron melt through thermal analysis. Design/methodology/approach Thermal analysis has recently grown as a tool for modeling the solidification behavior of ductile cast irons. Iron properties will be predicted by analyzing the cooling curve patterns of the melts and predicting the related effectiveness of inoculant processing. In this study, thermal analysis is used to evaluate the need for inoculation. Findings The amount and type of inoculation will affect the amount of undercooling during the solidification of ductile cast iron. It is found that the addition of 0.1 to 0.4 Wt.% inoculant lowers the austenite dendrite formation starting temperature while increasing the eutectic freezing temperature. Microstructure analysis revealed that the addition of inoculation increases the nodule count from 103 to 242 nodules. The beneficial effects of inoculation are sustained by an improved graphitization factor, which shows the formation of graphite nodules in the second phase of the eutectic reaction. Originality/value The inoculation treatment has improved metallurgical occurrences such as carbide to graphite conversion, graphite microstructure control, graphite nodule count at the start of solidification and the last stage of solidification, which determines the soundness of casting. The foundry industry can follow these steps for monitoring the solidification of ductile iron castings.

“…The green sand moulding control parameters such as clay quantity, moisture, bumping, sand size, and permeability were predicted using the Taguchimethod. Later, few kinds of research were performed to minimize the castings defects through Taguchi design of experiment, multi-functional analysis, and various non-conventional optimization techniques (Desai et al, 2016;Guharaja et al, 2006;Kumar et al, 2011;Kumaravadivel & Natarajan, 2013;Nandagopal et al, 2020;Pattnaik et al, 2013;Pulivarti & Birru, 2018;Santhosh & Lakshmanan, 2016). Hence, the many green sand mould experimental types of research have been made to reduce the casting defects on some parameters.…”

The green sand mould casting is an inevitable process to make large size and complex shape of the industrial components. The quality of green sand in mould is a significant phenomenon on casting quality. In this research, the number of ramming, sand thickness mould, and percentage of additives (western bentonite) mixing with sand have been considered to study the effects on permeability and hardness of mould by L27 orthogonal array. Greensand mould experiments have been conducted in the industry to observe the output parameter variations by Taguchi statistical analysis. It was revealed that the maximum permeability and minimum sand hardness have been obtained from the minimum number of ramming, thin sand thickness, and minimum mixing of additives in the sand. The confirmation tests were conducted to validate the predicted control parameter on responses.
