Promotion of Nutrient Uptake, Nutrient Use Efficiency and Apparent Nutrient Recovery of Wheat (Triticum aestivum L.) by Application of Phosphate and Potash Solubilizing Bacteria

Year: 2018

Type: article

Abstract: A field experiment was conducted on calcareous clayey soil at Junagadh (Gujarat) during rabiseason of 2014-15 to study the effect of phosphate and potash solubilizing bacterial inoculations on of nutrient uptake, nutrient use Efficiency and apparent nutrient recovery of Wheat (Triticum aestivum L.). The experimental results revealed that application of 45 kg P2O5/ha + phosphate solubilizing bacteria (PSB) seed inoculation + PSB soil application, being statistically at par with application of 45 kg P2O5 + PSB seed inoculation, significantly promoted phosphorus uptake by grain (17.98 kg/ha) and straw (5.72 kg/ha) as well as NUE of applied P (14.97 kg grain/kg P applied) and apparent nutrient recovery of P by 15.11%. While, Application of 45 kg K2O/ha + KSB seed inoculation + KSB soil application (K3) recorded significantly highest potassium uptake by grain (18.27 kg/ha) and straw (69.92 kg/ha). The treatment K3 (45 kg K2O/ha + KSB seed inoculation + KSB soil application) registered the highest potash use efficiency (15.73 kg grain/kg K applied) and apparent potash recovery (67.37%).
