“…Some micronutrients are necessary for plant growth, and excessive or too few micronutrients in the soil will cause adverse reactions in plants. It has been reported for many fruit trees that the application of Fe fertilizer can significantly increase the sugar content of fruits [43,44], but there are also reports that an excess of the element Fe will affect the root development and nutrient absorption of plants, thus interfering with the synthesis of sugars in plants, and thus reducing the sucrose content in fruits [45,46]. In addition, an excess of the element Fe may cause oxidative stress in the cells, affecting the normal progress of the tricarboxylic acid cycle, which produces succinic acid [47].…”

Soil mineral elements are the key factors affecting fruit quality, but which soil elements affect the sugars and organic acids of jujube fruit is still not clear. In this study, the fruit and soil of 18 major producing areas of the Tarim Basin were studied. By measuring the sugar and acid content in the fruits and element contents in the soil, the main soil mineral elements affecting the sugar and acid content in jujube fruits were identified. The results showed that the sugar components were mainly sucrose, glucose and fructose, and the organic acid components were mainly succinic acid, citric acid and malic acid. The fruits near the Kunlun Mountains had a higher ratio of sugar-to-acid and sweet-to-acid. Some elements in the soil of the Tarim Basin are abundant, such as the elements Ca, Fe, Mn and B, but the contents of the elements NO3-N, NH4-N, Zn and Mo are low. The contents of Ca, Mg and Mn were positively correlated with the contents of glucose, fructose and galactose. And the Fe, Ca, Mg and Mn were the main factors affecting the sugars and organic acid contents. Our study provides theoretical support for rational fertilization and efficient cultivation management of jujube.

Rice is a major grain crop in numerous countries. In lowland areas, high iron levels in the soil severely hinder its cultivation. The current study explored high-yielding and Fe-toxicity-tolerant irrigated lowland rice (340 lines) among a population derived from a cross between Suakoko 8 and Bao Thai in Edozighi and Ibadan, Nigeria. In contrast to Ibadan, the soils in Edozighi contain a significant amount of iron. For the stated purpose, we carried out a two-year experiment using an alpha lattice design. The data showed significant differences between genotypes for the days to heading, plant height, number of tillers per plant, number of panicles per plant, panicle length, and grain yield. The results revealed that multiple characteristics had both direct and indirect effects on cultivated rice yields. There was a direct and positive influence on the number of days in the 50% heading period (0.31), a direct and negative effect on plant height (−0.94), a direct and positive effect on tiller and panicle numbers, and a direct but negative effect on panicle length (−0.56). The leaf bronzing score was adversely correlated with yield, panicle length, and plant height, while it was positively correlated with the number of panicles, tillers, and days to heading. The findings showed significant changes in yield and yield characteristics between genotypes. Grain yields ranged from 283 to 11,700 kg/ha in the absence of iron in the soil, contrary to 0 to 8230 kg/ha in soil with iron toxicity, with losses estimated between 6 and 94%, demonstrating the resulting disaster. In contrast to the elite parents and varieties used in this study, the ten top genotypes exhibited smaller losses in yield. The authors strongly recommend using these lines for further studies as donors or releasing them in farmer fields in Africa.
