“…Further, application of SBG and CG to paddy soils facilitates the removal of exchangeable Na + by increasing the cross sectional area of conducting pores 31 and thus resulting in increased the permeability and generation of more organic acids that also mobilized the soil calcium 32 . Whereas, increased exchangeable Ca 2+ with the increased level of SBG and CG up to 900 kg ha − 1 in alkaline soils of paddy is due to the anaerobic condition of alkaline soil owing to wetland rice cultivation 20 . Exhaustive crops like maize also responded well to the application of SBG and CG by increasing the exchangeable Ca 2+ content in acid and neutral soils is ascribed to the higher supply of Ca 2+ through gypsum which increased the base saturation in soil and also due to release Ca 2+ during decomposition of gypsum 11,33 .…”

“…Regression between yield of paddy, maize and groundnut was signi cant with both SBG and CG application in all the soils, but SBG had higher yield response compared to CG. SBG, being a good source of nutrients such as calcium and sulphur along with micronutrients, its application would increase the availability of nutrients 11,16,17,18,19,20 and involved multiple roles in metabolism and improvement in vegetative structure, production of reproductive structures 21 thereby maintaining a balanced source-sink relationship. Positive and signi cant correlation between the application of gypsum (SBG and CG) and the yield of groundnut in both neutral and acid soils 17,18 .…”

“…In our study, alkaline soils of paddy had signi cantly increased the pH with the application of SBG and CG which may be attributed to alkalizing agents such as CaCO 3 , CaO and Ca (OH) 2 that are added through SBG during synthesis process and also the presence of sulphur in SBG may react with Fe and Al oxides and hydroxides to release OH − ions into soil solution and thus increase the soil pH and also buffering capacity of native soil may change the pH of the soil to certain extent 20,30 .…”

Changes in the pH of acidic, neutral, and alkaline soils in response to various rates and types of gypsum such as slag-based gypsum (SBG) and commercial gypsum (CG), and their effects on soil exchangeable calcium (Ca2+) & available sulphur (S) and yield of different crops were studied in field conditions. Statistical investigation such as linear regression model was used to know the relationship of gypsum application with crop yield revealed that application of SBG and CG was positively and significantly regressed with the yield of paddy, maize and groundnut in all the soils. Significant linear relationship with the pH of acid and neutral soils of paddy have been noticed with application of SBG and CG. Paddy grown in alkaline soil and maize grown in acid and neutral soils had a significant relationship between pH and SBG & CG application. Increased rate of application of SBG as basal and split significantly increased the kernel yield of groundnut. Application of SBG and CG linearly and significantly increased the exchangeable Ca2+ and available S content of soils in which paddy, maize and groundnut were grown. Acid soils responded well in increasing exchangeable Ca2+ and available S compared to other paddy, maize and groundnut soils. Linear relationship was noticed between exchangeable Ca2+ and pH of acid soils paddy, maize and groundnut as influenced by SBG and CG. Whereas, exchangeable Ca2+ content of alkaline soils of paddy also regressed strongly with pH. An increase in available S increased the soil pH of paddy, maize and groundnut, but it was significant with neutral soils of paddy and maize.

“…The pH ranges from 6.27 to 6.94 for all nine zeoponic formulations (Z1-Z9). The range from slightly acidic to neutral, is typically good for growth of plants and provides sufficient nutrient availability [24]. The electrical conductivity values range from 0.46 to 1.49 mS cm.…”

Variegated ornamental plants, known for their diverse leaf colors and high market demand, present a unique challenge in preserving long-lasting aesthetic appeal. This study focuses on the development and optimization of zeoponic formulations as effective plant growth media (PGM) to promote sustained growth and visual excellence in two variegated ornamental plants, Epipremnum aureum “Marble Queen” and Peperomia obtusifolia “Green Gold”. Zeoponics, composed of zeolite, compost, cocopeat, and fertilizers, is chosen for its high Cation Exchange Capacity (CEC) and aesthetic appeal due to its greenish-grey zeolite grains. Through greenhouse pot experiments and comprehensive PGM analysis, specific zeoponic formulations were identified for each plant species, yielding the most favorable results in terms of growth and appearance. The research explores the chemical properties of PGMs and observes plant growth parameters and chlorophyll content using Soil Plant Analysis Development (SPAD) measurements. The results show that the best formulation of fertilizer types and dosages for Epipremnum aureum “Marble Queen” is zeoponic Z7, with 10% Fe-EDTA, 10% Cu-EDTA, 10% Mn-EDTA, 10% Zn-EDTA while for Peperomia obtusifolia “Green Gold” is Z6, containing 4% Fe-EDTA, 4% Cu-EDTA, 4% Mn-EDTA, 4% Zn-EDTA. These findings offer valuable insights for enhancing the planting of variegated ornamental plants, benefiting the ornamental plant industry.
