“…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 .…”

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.

“…Application of YG resulted in more consistent and significant changes in yield and other associated yield components of groundnut compared to NG application (Table 3 ). Increase in pod and haulm yield of groundnut with YG application was mainly attributed to increased yield components and also due to higher availability of Ca, S, P, micronutrients and Si in the soil 38 , 40 . There is positive and significant correlation between pod and haulm yield of groundnut and total micronutrients and Si uptake.…”

“…Significantly higher uptake of micronutrients by haulm and kernel of groundnut mainly ascribed to higher availability of DTPA-extractable micronutrients in post-harvest soil as a result of YG application 40 . Positive and significant correlation between uptake of Fe, Mn and Cu by groundnut and their availability in the soil could be attributed to increased availability of these nutrients in soils with applied YG thereby increasing their uptake by groundnut.…”

Yellow gypsum (YG), a synthetic product from Linz-Donawitz slag containing high iron (Fe) (5.41%), zinc (Zn) (0.37%) and silicon (Si) (3.41%) can be used as a source of these nutrients along with calcium (Ca) and sulphur (S) for groundnut production. Three field experiments were conducted to know the effect of different rates (500 and 625 kg YG ha−1) and time of application (basal alone and basal + split) of YG on growth, yield and economic returns of groundnut, and micronutrient and Si availability and their uptake in comparison with basal application of 500 kg natural gypsum (NG) ha−1. Basal alone and basal + split application of YG significantly increased the growth, yield and economic returns of groundnut. Further, it increased the soil pH, availability of micronutrients, Si and their uptake by haulm and kernel of groundnut over NG. Irrespective of the location, YG application recorded higher plant available nutrient (PAN) coefficient of micronutrients, while NG application recorded higher PAN recovery coefficient of Si. Basal + split application of YG resulted in better growth and yield of groundnut than basal application of YG. In conclusion, YG can be a potential alternative for NG as a source of Fe, Zn and Si along with Ca and S for groundnut production.

Agricultural rainfed areas of Pakistan have been facing several issues in recent years, e.g., soil erosion, nutrient runoff, and soil dependency on rainfall for crop growth. Wheat is considered a major staple crop in Pakistan. The main concern in these regions is to conserve soil moisture as the crop depends on the moisture obtained by rainfall. Gypsum is considered one of the best moisture conservers, especially for rainfed areas. Hence, this study was initiated (1) to explore the effects of gypsum on soil moisture conservation and (2) to reveal the effects of gypsum on soil macronutrients, sulfur (S), calcium (Ca), nitrogen (N), phosphorus (P), and potassium (K) uptake, and, eventually, wheat yield. The study was conducted from July 2014 to April 2015 in the rainfed Pothohar region of Pakistan. The recommended mineral fertilizers (N120P80K60) along with the following gypsum treatments: T1 = gypsum @ 0 Mg ha−1 (0 kg plot−1), T2 = gypsum @ 1 Mg ha−1 (0.6 kg plot−1), T3 = gypsum @ 3 Mg ha−1 (1.8 kg plot−1), and T4 = gypsum @ 4 Mg ha−1 (2.4 kg plot−1) were applied. The Chakwal-50 wheat variety was sown, followed by gypsum application. The maximum moisture was recorded under the soil of treatment T4 each month. The soil moisture was conserved up to 21% (surface) and 23% (sub-surface) in January and February 2015, respectively, with a 4 Mg ha−1 gypsum application. The highest nitrogen (N, 448.68 kg ha−1), phosphorus (P, 50.6 kg ha−1), potassium (K, 185.7 Kg ha−1), sulfur (S, 9.75 kg ha−1), and calcium (Ca, 35.5 kg ha−1) uptake values were observed in treatment with a 3 Mg ha−1 gypsum application (p < 0.05). The mean values of the grain yield ranged between 1903.4 (T1) and 2387.2 (T4) kg ha−1. Compared with the yield under T1, the grain yields under treatment T2, T3, and T4 were increased by 11%, 24%, and 25%, respectively. The straw yield ranged between 2446 and 2767 kg ha−1. There was no noticeable impact of gypsum application rates on the straw yield of the wheat crop (p > 0.05). Overall, treatment T3 was found to be optimal for conserving soil moisture, a better nutrient uptake, and, ultimately, the wheat crop yield with less input cost.
