Rice bean, a lesser known pulse, has excellent nutritive value. The seed yield of the crop is higher as compared to other pulses of the Vigna family. In the present study thirty diverse rice bean genotypes were evaluated for nutritional and morpho-physiological characteristics for selecting overall superior genotypes. Variations were observed for crude protein (16.1–19.12%), carbohydrates (59.28–76.89%), ascorbic acid (0.19–0.80 mg/100 g), crude fibre (4.23-6.0%), limiting amino acids, namely tryptophan (0.85–2.42 g/16 g N) and methionine (0.52–0.67 g/16 g N), and ether extract (0.57–2.13%). Anti-nutritional factors, such as total phenolics, total tannins, condensed tannins, hydrolysable tannins and α-amylase inhibitor, also varied to a considerable extent. The cumulative grading of the genotypes based upon nutritional and morpho-physiological attributes revealed that the genotypes JCR-76, IC-137200, IC-140796 and IC-137189 were nutritionally superior genotypes for consumption.

The physical, chemical and mineralogical characterization of the constituents of magnesium-rich synthetic gypsum produced in a rare earth-refining plant located in Gebeng, Pahang, Malaysia was conducted through elemental chemical analysis, scanning electron microscopy with Energy Dispersive X-ray (EDX)-analyzer, thermal analysis, X-ray fluorescence and X-ray diffraction. The crystalline nature of the by-product was studied using FTIR spectroscopy. Elemental analysis confirmed the presence of Ca and Mg, which are essential macronutrients required by plants and this Ca alongside the high pH (9.17) of MRSG may confer on the material a high acid neutralization capacity. From the result, it was observed that the studied by-product is a heterogeneous crystalline material comprising of gypsum (CaSO4.2H2O) and other major components such as calcium (magnesium) compounds (hydroxide, oxide, silicates, and carbonate) and sulfur. These aggregates may contribute to give an acid neutralization capacity to MRSG. The XRD study of MRSG indicated a high content of gypsum (45.4%), shown by the d-spacing of 7.609 Å (2-theta 11.63) in the diffractogram. The infrared absorption spectra of MRSG indicate close similarities to mined gypsum. The results of the characterization indicated that MRSG has valuable properties that can promote its use in amending soil fertility constraints on nutrient-deficient tropical acid soils.
