Effect of integrated nutrient management practices on soil properties and nutrient availability to wheat (Triticumaestivum L.) under saline and non saline irrigation water

Abstract

Integrated nutrient management studies in wheat (T. aestivum L.) cultivar WH-711 under saline and non saline irrigation water conducted duringrabi seasons of 2011-2012 and 2012-2013at Hisar, Haryana. Available N, P, K (kg/ha) and organic carbon (%) were significantly higher under canal water treatment (173.3, 12.73, 246.3, 0.364) than saline water (171.3, 12.50, 244.5, 0.352), respectively, while soil pH did not differ significantly after completion of the experiment. Significantly higher electrical conductivity was observed under saline water (1.25 dS/m) as compared to canal water treatment (0.42 dS/m). Among inoculation treatments, available N, P, K and organic carbon were significantly higher under Azotobacter ST3 +Pseudomonas P36 + vermicompost @ 5t/ha (173.7, 12.84, 246.8, 0.369) than no inoculation (170.6, 12.34, 243.7, 0.349), respectively, while soil pH and EC did not differ significantly. Application of 125%RDF resulted insignificantly higher available N, P and organic carbon173.2, 12.81, 0.364) as compared to 100 (172.2, 12.60, 0.357) and 75%RDF (171.6, 12.44, 0.353), respectively, while available K, soil pH and EC did not differ significantly under various recommended dose of fertilizers.
