“…Treating common soybeans with increasing calcium concentrations (1.10, 1.65, 2.20, 2.75, and 3.30 mmol L−1) increases the dry weight of soybean stems, leaves, and roots and the fresh weight of soybean seeds [9]. Administering CaCO 3 by spraying leaves during rice growth improves rice yield and quality and enhances rice resistance to insects [33].…”

Taiwanese quinoa (Chenopodium formosanum Koidz, commonly known as djulis) is a close relative of quinoa, is rich in nutritional value and high active components, such as, betaine and polyphenols, and is a vital food crop. We investigated the effects of calcium carbonate on the growth and physiology of Djulis sprouts because calcium is an essential nutrient for plants that can strengthen a plant’s root system and improve its nutrient absorption; moreover, under abiotic stress, calcium transmits messages to enhance cell tolerance. Experiments were conducted using 0, 1.25, 2.5, and 5 mM calcium carbonate hydroponic liquid treatment. Treatment with 5 mM calcium carbonate promoted the growth of djulis; specifically, root length, plant height, aboveground fresh weight, and dry weight increased by 55%, 12%, 37%, and 17%, respectively. In further investigation of the physiological change of djulis sprouts treated with calcium carbonate, the results showed that after 5 days of treatment with 5 mM calcium carbonate, the contents of hydrogen peroxide and malondialdehyde decreased significantly while the chlorophyll content increased significantly. Antioxidant enzyme activity was significantly improved. The activities of superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase were increased by 42%, 25%, 35.7%, and 56.4%, respectively, and the calcium content of the aboveground and underground plant parts was increased fourfold and threefold, respectively. The content of proline, regarded as an osmoprotectant, was reduced by 12%. Thus, we concluded that treatment of djulis sprouts with 5 mM calcium carbonate can improve their antioxidant capacity, reduce the content of reactive oxygen species, and promote crop growth.

“…The enhancement of photosynthetic pigment content, the management of antioxidant activity, water relations, accumulation of osmolytes, and nutritional balance have all been linked to Ca's beneficial effects on abiotic stress intolerance [ 30 ]. Additionally, spraying CaCO 3 -NPs showed pivotal roles in improving plant vigority, flowering, coloring, biotic and abiotic resistance and post-harvest quality characteristics [ 31 ]. On the other hand, Ca supplementations showed major roles in increasing the size and quantity of flower buds, reinforcing the flower’s stalk, and accelerating plant growth and development [ 32 ].…”

The use of the system of rice intensification (SRI), deficit irrigation and foliar fertilizer application has proven to be effective in enhancing water productivity (WP) individually. However, information on their combined effects is limited. Therefore, this study evaluated the effects of integrating deficit irrigation and carbonate foliar fertilizer (Lithovit) application into the SRI on WP. This study was conducted under the Mkindo Irrigation Scheme in Mvomero, Morogoro, Tanzania, during the dry and wet seasons (October 2020 to June 2021). The experiment was laid out in a split‐plot design with three levels of irrigation for the main plots, which were 100% of the irrigation water requirement (40 mm) imitating the SRI alternate wetting and drying pattern and induced deficit irrigation applied at 80% and 50% of the irrigation water requirement as IR100, IR80 and IR50, respectively. In addition, there were five subplot fertilizer treatments: (A) diammonium phosphate (DAP) and urea (normal practice); (B) DAP, urea and 100% of the recommended foliar fertilizer (Lithovit standard); (C) DAP, 50% (Lithovit and urea); (D) Lithovit standard only; and (E) no fertilizer. The combined irrigation and fertilizer treatments tested were IR100A, IR100B, IR100C, IR100D, IR100E, IR80A, IR80B, IR80C, IR80D, IR80E, IR50A, IR50B, IR50C, IR50D and IR50E. The highest and lowest WP were 0.851 kg/m3 and 0.562 kg/m3 for IR80B and IR80E, respectively, for the dry season. For the wet season, the highest and lowest WP were 0.540 kg/m3 and 0.306 kg/m3 for IR50B and IR50E, respectively. WP is attributed to the SRI and Lithovit, which act as long‐term reservoirs for carbon dioxide, especially during water stress periods. Thus, integrating deficit irrigation and carbonate foliar fertilizers improves WP in rice cultivation. This study demonstrated that this approach can lead to significant water savings while improving rice yields. This integrated approach can be adapted and optimized based on the specific conditions and requirements of different agroecological contexts.
