“…The appropriate combination and effective doses of essential elements can positively improve the yield and quality of turmeric [18]. Soils deficient in active nutrients may negatively impact the quality and effectiveness of medicinal plants [19]. Improving plant nutrition will improve the quantity and quality of turmeric [20][21][22].…”

An experiment was carried out to investigate the effects of different mineral fertilizers on mineral contents in turmeric rhizomes and soil enzyme activities and soil properties under field conditions in Uzbekistan. The present study is the first report on the impact of mineral fertilizers in turmeric rhizomes and soil enzymes and soil properties in Uzbekistan. The experiment was carried out with four treatments: T1—Control, T2—N75P50K50 kg/ha, T3–N125P100K100 kg/ha, and T4—N100P75K75 + B3Zn6Fe6 kg/ha. Turmeric rhizomes and soil samples were collected from field experiments at the Surkhandarya scientific experimental station of the vegetable, melon crops and potato research institute, Surkhandarya, Uzbekistan. The data showed that T3—the NPK (125:100:100 kg/ha) and T4—the NPK + BZnFe (100:75:75:3:6:6 kg/ha) treatments significantly enhanced K content by 27–21%, Ca content by 43–38%, and P content by 54–17% in turmeric rhizomes as compared to control without fertilizer. A maximum of turmeric rhizome microelements content was recorded with T4, which also resulted in improved Fe, Zn, Cu, Cr, and Mo contents in turmeric rhizomes and mineral contents of soil compared to other treatments. This treatment significantly enhanced active P content by 34%, active K content by 25%, total P content by 62%, total K content by 14%, and the activities of soil urease, invertase, catalase, and phosphatase over those in the control. The present study results suggest that the application of NPK + BZnFe (100:75:75:3:6:6 kg/ha) improves macro and micronutrient contents in turmeric rhizomes and activities of soil enzymes and physicochemical properties of soil.

Eutrophication is increasing with intensive agricultural activities as a global environmental challenge, especially in developing countries. In order to establish the effects of long-term reducing fertilization and straw returning on nitrogen (N) and phosphorus (P) loss in surface runoff due to intensive cultivation in the Yangtze River basin, China, we conducted a 7-year field pilot experiment with rice-wheat rotation in the fifth largest fresh water lake basin. The treatments included no fertilization (CK), conventional fertilization (Conv. Fert.), optimized fertilization (Optim. Fert.), nitrogen reduction by 30% (70%N), P reduction by 50% (50%P), and N reduction by 30% and P reduction by 50% + straw returning (70%N50%P+Straw). Results showed that the average wheat yields in reducing fertilizer treatments (70%N, 50%P, and 70%N50%P+Straw) slightly decreased by 1.21%, 5.26%, and 1.17%, respectively, compared to those with the optimized fertilizer, whereas average rice yields slightly increased by 3.71%, 0.64%, and 1.23%, respectively. However, the reducing fertilizer treatments (70%N50%P+Straw) significantly reduced the loss of N and P in surface runoff compared with Conv. Fert. and Optim. Fert. Total P and dissolved P in surface runoff water in rice seasons was predictable and modeled. The annual average N, P, and K fertilizer efficiency for rice-wheat rotation ranged in 21%–42%, 12%–38%, and 35%–53%, respectively. Considering the yields of rice and wheat along with eco-environmental benefits of reducing N and P loss in surface water, 70%N50%P+Straw treatment was the best treatment for Chaohu region. This long-term field study recommends the employment of the reduced chemical fertilizer by 30% N and 50% P in Chaohu basin for rice and wheat crops with the maximum reduction of runoff N and P and the highest fertilizer (N and P) efficiency with reasonable high crop yields. This is especially important for farmers in developing countries in achieving economical, ecological, and environmental benefits in sustainable modern agriculture to feed the increasing global populations.

“…Various studies have shown that higher Mg concentration enhances the plant resistance to various environmental stresses such as light, heat, and drought (Cakmak, 2013;Gransee and Führs, 2013;Mengutay et al, 2013). Moreover, Mg deficiency also interferes with N metabolism, which has important implications for crop production and the environment (Grzebisz, 2013;Zhang et al, 2021). Therefore, Mg deficiency would affect plant development and the formation of yield and quality.…”

Orchards in acid soils are at risk of magnesium (Mg) deficiency which negatively affects the plant growth, yield, and quality. However, the impacts of Mg supplementation on fruit yield, quality, and environmental and economic benefits have only been rarely addressed. We conducted 15 pomelo (Citrus grandis L.) orchard trials in South China to assess more efficient integrated nutrient management (INM) practices, including local farmer fertilization practices (FP; average application rate of nitrogen, phosphorus, and potassium were 1,075 kg N ha−1, 826 kg P2O5 ha−1, and 948 kg K2O ha−1, respectively), optimum fertilization practice (OPT; average application rate of nitrogen, phosphorus, and potassium were 550 kg N ha−1, 295 kg P2O5 ha−1, and 498 kg K2O ha−1, respectively) and optimum fertilization supplemented with Mg (OPT+Mg; average application rate of Mg was 196 kg MgO ha−1). The results showed that the yield, total soluble solid-to-titratable acidity ratio, and economic benefits under OPT practice were not significantly different from those of FP, while those of OPT+Mg were significantly higher than those of FP, by 8.76, 8.79, and 15.00%, respectively, while titratable acidity contents were significantly lower by 7.35%. In addition, compared with those from FP, the energy inputs and greenhouse gas (GHG) emissions from OPT were 31.00 and 26.48% lower, and those from OPT+Mg were 26.71 and 23.40% lower, respectively. Compared with those of OPT, the marginal efficiency of energy, GHG emissions, and capital of Mg under OPT+Mg were reduced by 62.30, 44.19, and 21.07%, respectively. Overall, adopting OPT+Mg for pomelo production could further enhance yield, fruit quality, and economic benefits while reducing the environmental burdens.
