“…Potted peanut plants treated with CL, T6, T4, and P1 were all slightly taller than the CK (Figure 3). Reasonable nutritional growth of peanut plants is the basis for obtaining higher yields [25] and is a prerequisite for yield formation; studies on rice, wheat, corn, soybean, and other crops have confirmed that the growth status of the aboveground is closely related to economic yield, so ensuring healthy growth of peanut plants is essential for stable and increased yields [26]. The use of peanut rhizobacteria peanut rhizobacteria promoter had a positive effect of promoting the growth and development of peanut, which had different degrees of improvement on the aboveground biological and economic yield of peanut [27].…”

Improper fertilization has become an essential factor limiting peanut yield and quality improvement. To improve peanut yield and quality, the effects of different fertilizer additives on peanut growth and yield were investigated. In this work, the effects of four fertilizer additives produced by microorganisms (CL, T6, T4, and P1) on peanut growth and yield were evaluated through pot and field trials. The results indicated that all fertilizer additives significantly increased the branch number and biomass of peanuts compared to the control. Additionally, T6 and CL treatments led to significantly higher peanut yields in the field. The aboveground nitrogen concentration of peanuts treated with CL and T6 was also significantly higher than that of the control, while T4 treatment did not show a significant difference. Overall, CL and T6 had the best positive effect on the growth of peanuts. The potential application values of CL and T6 in peanuts showed that fertilizer additives produced by microorganisms could be used as effective measures to achieve highly efficient production in agriculture.

“…The positive properties of gypsum and its high solubility in the soil and the presence of elements such as calcium and sulfur in its structure could cause an increase in the oil content with increasing calcium levels that were provided by gypsum [40,53,54]. Furthermore, Arnold et al [55] reported that the gypsum fertilization achieved the highest seed calcium content.…”

The absence of calcium decreases the production of peanuts compared to any other element. To investigate the influence of calcium (Ca) applications on the production and seed quality of four diverse peanut cultivars from different regions—USA (NC-7), Egypt (Giza-6) and Nigeria (Samnut-23 and Samnut-24)—under clay soil conditions, two experiments were carried out at the Agricultural Experimental and Research Station, Cairo University, Egypt, during the two seasons of 2016 and 2017. The experimental design was a randomized complete block in a spilt-plot arrangement with three replications. The main plots were allocated to four peanut cultivars (Giza-6, Samnut-23, Samnut-24 and NC-7), and the sub-plots were devoted to calcium applications (soil application in the form of calcium sulfate dihydrate, foliar application in the form of calcium oxide and the control treatment of distilled water). Results indicated that all four peanut cultivars responded differently to the application of calcium fertilizers. The calcium application significantly enhanced peanut growth, yield components, biological, pod, seed, oil yields, seed oil, free fatty acids and seed calcium percentages in different cultivars. Soil calcium application significantly improved peanut production compared to foliar calcium application. NC-7 cultivar treated with the soil Ca application resulted in the maximum values of biological yield (92.9-ton ha−1), pod yield (6.8-ton ha−1), seed yield (4.4-ton ha−1), oil yield (2247.0 kg ha−1), pod index (203.2 g) and seed index (84.1 g). The interaction between the NC-7 cultivar and soil calcium applications is recommended to attain the best combination, leading to the highest yield and seed quality of peanuts.

“…The topsoil control, however, produced a high exchangeable calcium content during the major rainy season (Figure 4). The increased exchangeable calcium with increasing gypsum is attributable to the high proportion of calcium in gypsum [29]; [30]. The topsoil control's high calcium during the major season can be attributed to low precipitation received during the major rainy season which slowly enhanced the availability of exchangeable calcium in topsoil solution [31].…”

Depending on soil, climate and crop characteristics exposed subsoils can be amended with gypsum for agricultural activities when topsoil is inadequate as a result of natural and geophysical activities. To determine how exposed subsoil amendment with gypsum interact with weather patterns to influence soil chemical properties, cucumber growth, fruit characteristics and heavy metal concentration, a two-seasonal experiment was conducted in the major and minor rainy season of 2020 in the Ahafo-Kenyasi Mining Area in Ghana. The experiment was laid out as a 6x2 factorial arranged in randomized complete block design, consisting of 6 gypsum application rates (20 ton/ha, 40 ton/ha, 60 ton/ha, 80 ton/ha, 0 ton/ha (subsoil control) and 0 ton/ha (topsoil control)) in two rainy seasons and replicated three times. The results show that gypsum application and rainy seasons interact to significantly influence soil chemical properties, cucumber growth and fruit characteristics. Increasing gypsum application resulted in decreased organic carbon, increased calcium, increased available P, increased exchangeable magnesium (Mg), increased pH during both major and minor rainy seasons. Vine length, number of leaves, number of fruits per plant and fruit weight of cucumber were increased with increasing gypsum application during the minor rainy season. In spite of exceeding permissible limits in soils and crops, arsenic (As), cadmium (Cd) and mercury (Hg) showed similar concentrations (below 2 mg/kg) in cucumber during the minor and major rainy seasons across gypsum treatments. Lead (Pb) concentration in cucumber was significantly higher in the major season across treatments. There was no difference in lead (Pb) concentration for treated vs untreated, and no increase across the amendment range. Further studies on how heavy metals in soil and plants interact with plant phytochemicals in ecosystems and living tissues are recommended.
