“…The highest IC50 value for reducing power observed in Jalal Abad-14 (29.28 mg/ml), whilst the lowest was revealed in Sha Lawangi (10.06 mg/ml). The current finding indicates that genetic variation, soil types and environmental conditions may have contributed to the antioxidant capacity of varieties and the data suggests that the varieties have moderate antioxidant activity [22,23]. The relation of AA and other grain properties is shown in Fig.…”

The present study was conducted to evaluate the antioxidant activity, grain traits and quality contents in Afghanistan’s selected rice varieties. The antioxidant capacity was measured using DPPH (1,1-diphenyl-2-picrylhydrazyl) and Reducing Power methods. Grain length, grain width and grain thickness were in the range of 5.4-7.6, 1.7-3.2, and 1.5-2.2 mm respectively. Selah Zoodras, Taram Irani and Attai-1 had the longest grain length whereas Luke was associated with high width and thickness among the varieties. Protein, amylose and lipid content varied from 6.5-9.9, 20.3-23.5, and 10-18% respectively. Barah Kunduz showed the highest protein and lipid content while Selah zoodras was associated highest amylose content. The selected rice varieties possessed moderate antioxidant activity and their physiochemical properties were not correlated with antioxidant capacity. Results of this study provided useful information on the selection and production of rice varieties with high nutritional and pharmaceutical values in Afghanistan.

“…The concentration of Zn was high, with values ranging from 1.2 to 181.0 mg kg −1 . The addition of Zn into the soils during the flood was in a way enhanced their productivity as shown by the study of Panhwar et al [22] who found that rice grown in the soils of the Kelantan Plains responded positively to Zn application. They found that due to Zn application, not only rice yield was increased, but also the quality of its grains was enhanced.…”

Heavy rain falling on land at the upper reaches of the Kelantan River, Malaysia, on December 2014, had resulted in severe soil erosion and untold damages to croplands. The lower reaches of the river were heavily silted with infertile materials considered unfit for crop production. A study was conducted to explain why the flood phenomenon occurred, to determine the physico-chemical properties of the sediments silted in the Kelantan Plains and to propose measures for soil mitigation. Results showed that the silted sediments were characterized by the presence of quarts, mica, feldspars, kaolinite, gibbsite and hematite believed to come from the top-and subsoil of the upland areas. The sediments' pH was very low and Al and/or Fe contents were very high, while nitrogen and carbon contents varied from area to area. Soils in the Kelantan Plains badly affected by this great flood needed to undergo proper ameliorative program. The most appropriate measure would be to apply ground magnesium limestone in combination with bio-fertilizer fortified with beneficial microbes that would increase their pH to a level above 5, which consequently eliminates Al 3+ and/or Fe 2+ that causes toxicity to the crops growing on them. The organic material so added would enhance the formation of soil structures. It is advised that the farming communities in the upper reaches of the Kelantan River would have to follow the advice advocated by the Department of Agriculture, Peninsular Malaysia, via MyGAP initiative, in order to sustain agricultural production on their land.

“…The reason for this is that the fertility of the soil had been improved somewhat by GML application, which increased the water pH, while the concentration of Al 3+ and/or Fe 2+ was concomitantly reduced. The growth of rice was further enhanced by the increase in Ca, Mg, Zn, and Cu contents [35,38]. Basalt treatment gave low grain yield in the first season, but with time, it increased to that of the GML treatment.…”

Applying Limestone or Basalt in Combination with Bio-Fertilizer to Sustain Rice Production on an Acid Sulfate Soil in Malaysia

Abstract:A study was conducted to determine the efficacy of applying ground magnesium limestone (GML) or ground basalt in combination with bio-fertilizer to sustain rice production on an acid sulfate soil in Malaysia. Soils from Kelantan Plains, Malaysia, were treated with GML, ground basalt, bio-fertilizer, GML + bio-fertilizer, and ground basalt + bio-fertilizer (4 t¤ ha ¡1 each). Results showed that soil fertility was improved by applying the soil amendments. GML and basalt contain some Zn and Cu; thus, application of these amendments would increase their contents in the soil needed for the healthy growth of rice. Basalt applied in combination with bio-fertilizer appeared to be the best agronomic option to improve the fertility of acid sulfate soils for sustainable rice production in the long run. In addition to increasing Ca, Mg, Zn, and Cu reserves in the soil, water pH increased and precipitated Al 3+ and/or Fe 2+ . Ground basalt is cheaper than GML, but basalt dissolution in the acidic soil was slow. As such, its ameliorative effects could only be seen significantly from the second season onwards. The specially-formulated bio-fertilizer for alleviating the infertility of acid sulfate soil could also enhance rice growth. The use of the bio-fertilizer fortified with N 2 -fixing bacteria is a green technology that would help reduce NO 3 ¡ and/or NO 2 ¡ pollution and reduce the cost of rice production. The phosphate-solubilizing bacteria (PSB) present in the bio-fertilizer not only increased the available P, but also helped release organic acids that would inactivate Al 3+ and/or Fe 2+ via the process of chelation.
