Response of Physic Nut Trees to Liming of Acidic Soils

Response of physalis (Physalis peruviana L.) to liming in acidic soils

“…Adequate Ca and Mg levels for the common bean grown on Oxisol soils were found to be approximately 20 and 10 mmol c kg -1 for Ca and Mg, respectively, for conventional planting (Fageria et al, 2008), and 17.0 mmol c kg -1 for Ca and 5.7 mmol c kg -1 for Mg to maximum growth of the physic nut plants in Brazilian soils (Silva et al, 2016). The ideal saturation ratios for Cation-exchange capacity were 65 to 86% Ca, 6 to 12% Mg, and 2 to 5% K, with wide variations in Ca/Mg/K ratios in the soil (Rietra et al, 2017), and for the growth of physic nut, optimal Ca, Mg and K saturation was 36.0, 12.0 and 3.8 %, respectively, in two Brazilian soils (Silva et al, 2016). However, to date, few studies have evaluated soil chemical attributes and optimization conditions for physalis farming.…”

“…As the clay concentration increases, a higher concentration of limestone is required to achieve maximum growth and crop yield (Fageria et al, 2008). Liming is widely used to increase crop yield in acidic soils (Bhat et al, 2010), being positively correlated with improvements in growth, productivity and quality of many crops, such as raspberry (Sikiric et al, 2011), wheat (Kostic et al, 2015), physic nut (Silva et al, 2016), and cassava (Anikwe et al, 2016). Other studies on soil correction using limestone in other crops have stated the importance of other variables, limestone application method, target depth, soil texture, organic matter concentration, soil pH, application time and frequency, feedstock, and costs of soil correction (Takasu et al, 2006, Bhat et al, 2010, Kostic et al, 2015.…”

“…Soil acidity is one of the main limiting factors of agricultural activities (Li et al, 2016. Liming is an essential practice in agricultural systems (Fageria et al, 2007, Sikiric et al, 2011, Anikwe et al, 2016, Silva et al, 2016 and is widely used to increase yield in acidic soils (Caires et al, 2006, Fageria et al, 2008, Bhat et al, 2010, Kostic et al, 2015. The application of lime decreases toxic concentrations of aluminum (Al) (Steiner et al, 2012, Li et al, 2016, Raboin et al, 2016, manganese (Mn), and iron (Fe) in the soils (Sikiric et al, 2011).…”

“…Moreover, the addition of dolomitic limestone increases Ca and Mg concentrations in the soil (Li et al, 2016, Rietra et al, 2017 and improves the cation balance in the soil (Rietra et al, 2017). The soil pH values for optimum crop production should be between pH 6.0 and 7.0 (Caires et al, 2006, Fageria et al, 2008, with base saturation values ranging from 60 to 80% (Fageria et al, 2008), and for physic nut crop, a pH above to 6.0 and base saturation of 52% provided maximum plant growth (Silva et al, 2016). Adequate Ca and Mg levels for the common bean grown on Oxisol soils were found to be approximately 20 and 10 mmol c kg -1 for Ca and Mg, respectively, for conventional planting (Fageria et al, 2008), and 17.0 mmol c kg -1 for Ca and 5.7 mmol c kg -1 for Mg to maximum growth of the physic nut plants in Brazilian soils (Silva et al, 2016).…”
