The amount of soil contaminated with heavy metal increases due to urbanization, industrialization, and anthropogenic activities. Quinoa is considered a useful candidate in the remediation of such soil. In this pot experiment, the phytoextraction capacity of quinoa lines (A1, A2, A7, and A9) against different nickel (Ni) concentrations (0, 50, and 100 mg kg-1) were investigated. Required Ni concentrations were developed in polythene bags filled with sandy loam soil using nickel nitrate salt prior to two months of sowing and kept sealed up to sowing. Results showed that translocation of Ni increased from roots to shoots with an increase in soil Ni concentration in all lines. A2 line accumulated high Ni in leaf compared to the root as depicted by translocation factor 3.09 and 3.21 when grown at soil having 50 and 100 Ni mg kg-1, respectively. While, in the case of root, A7 accumulated high Ni followed by A9, A1, and A2, respectively. There was a 5–7% increased seed yield by 50 mg kg-1 Ni in all except A1 compared to control. However, growth and yield declined with a further increase in Ni level. The maximum reduction in yield was noticed in A9, which was strongly linked with poor physiological performance, e.g., chlorophyll a, b, and phenolic contents. Ni concentrations in the seed of all lines were within the permissible value set (67 ppm) by FAO/WHO. The result of the present study suggests that quinoa is a better accumulator of Ni. This species can provide the scope of decontamination of heavy metal polluted soil. The screened line can be used for future quinoa breeding programs for bioremediation and phytoextraction purpose.

AbstractA study was conducted to evaluate the possibility of cranberry cultivation on mineral soils and to assess the influence of vegetative biomass development, generative growth and yield components on the yielding of three cranberry cultivars originating in the USA (Stevens, Pilgrim and Ben Lear) at two locations in Poland. The key biometrical traits involved in yield formation were taken into account, and the soil and plant chemical conditions were evaluated. All of the measured biometrical characteristics were strongly influenced by the location and the year of cultivation, and varietal differences were also noted. The most important determinants that explained yield variation were: the number of uprights per square meter, floral induction and berry set. However, the participation of each component in yield variation was strongly affected by the location, age of plantation and to a minor extent by the cultivar. The study confirmed the possibility of cranberry cultivation on mineral soils with a low pH. The biggest average yield of the three years was collected from cv. Stevens as cultivated on sandy soil in contrast to the same cultivar grown on sandy loam soil. In the case of sandy loam soil after acidification, cv. Pilgrim appeared to be a relatively better yielding cultivar.

As anthropogenic activities rise over the world, representing an environmental threat, soil contamination and treatment of polluted areas have become a worldwide concern. Bioremediation is a sustainable technique that could be a cost-effective mitigating solution for heavy metal-polluted soil regeneration. Due to the difficulties in determining the optimum bioremediation methodology for each type of pollutant and the lack of literature on soil bioremediation, we reviewed the main in-situ type, their current properties, applications, and techniques, plants, and microbe’s efficiency for treatment of contaminated soil. In this review, we describe the deeper knowledge of the in-situ types of bioremediation and their different pollutant accumulation mechanisms.

Abstract. Although various organic and inorganic mulches are used for soil conservation purposes, the comparative effectiveness of them on soil characteristics has not been comprehensively considered from different aspects. The present study is therefore an attempt to determine the efficiency of straw mulch, manure and TA-200 polyacrylamide with respective rates of 500, 300 and 50 g m-2, respectively, in changing sediment concentration and soil loss. The experiments were conducted for sandy-loam soil (collected from the top 0–20 cm-layer) taken from a summer rangeland, the Alborz Mountains, Northern Iran under laboratory conditions with simulated rainfall intensities of 30, 50, 70 and 90 mm h-1 and the slope of 30%. The results showed that the straw mulch decreased soil concentration at rate of 45.60% compared to the control plots, and performed better than manure (8.98% reduction) and PAM (4.74% reduction). The results showed that the maximum reduction in sediment concentration and soil loss for all soil amendments occurred in the rainfall intensity of 90 mm h-1 with the rates of 58.69 and 63.24%, for straw mulch, 14.65 and 13.14%, for manure and 20.15 and 23.44% for TA-200, respectively.

A field experiment was conducted during Kharif 2017 at ZARS, University of Agricultural Sciences, Bengaluru to study the influence of different levels of Farm Yard Manure (FYM) and Jeevamrutha on growth and yield of Sunflower in red sandy loam soil. There were nine treatment combinations laid out in factorial randomized complete block design, which were replicated thrice. The experimental results revealed that, the application of FYM at 150 per cent nitrogen equivalent and jeevamrutha at 1500 L ha-1significantly influenced growth parameters like plant height, number of leaves, leaf area, leaf area index and total dry matter production. The interaction effect of FYM and jeevamrutha was significant in enhancing the seed yield of sunflower due to improvement in yield attributes like head diameter, number of seeds per head, hundred seed weight and seed yield per plant.

An experiment was conducted on farmer’s field in Khajura, Banke for site specific nutrient management (SSNM) in hybrid maize (Rajkumar) during winter season of 2016. The climatic condition of the experimental location was humid sub-tropical and sandy loam soil occurring intense summer and severe winter. Average annual rainfall of 1000 -1500 mm occurs in the location. The experiment was replicated 4 times in Randomized complete block design having plot size of 4.8 x 3 m2. Row to row spacing was maintained at 60 cm and plant to plant at 25 cm for each plot. There were six treatments including farmers fertilization practice (27.6:27.6:18 NP2O5K2O kgha-1) as a check, recommended dose of fertilizer (160:60:40 NP2O5K2O kgha-1), site specific nutrient management (212.9:66.8:280.8 NP2O5K2O kgha-1), 75% SSNM (372.6:116.9:491.4 NP2O5K2O kgha-1), FP-N, FP-P, SSNM-K (27.6:27.6:280.8 NP2O5K2O kgha-1) and SSNM-N, FP-P, FP-K (212.9:27.6:27.6 NP2O5K2O kgha-1). Among the treatment combination; application of SSNM we can increase the yield by 193% over farmer fertilization practice. Recommended dose of fertilizer and 75 percent SSNM also increase the yield by 138% and 130.4% respectively compared to farmer fertilization practice. 88% and 53.5% more increment could also be obtained through the application of only SSNM dose of nitrogen and SSNM dose of potassium respectively over farmer fertilization practice.
