Effect of integrated use of inorganic and organic sources of nitrogen on nutrient uptake by wheat and soil fertility

A field experiment was conducted at Agronomy Research Farm of CCS Haryana Agricultural University, Hisar during Rabi seasons of 2017-18 and 2018-19 to Effect of integrated use of inorganic and organic sources of nitrogen on nutrient uptake and soil fertility of wheat. The experiment was laid out in randomized block design with three replications consisting of ten treatments combinations i.e. T1-Control; T2-100% recommended dose of nitrogen (RDN) + 25% N through FYM; T3-100% RDN + 25% N through vermicompost; T4-75% RDN + 25% N through FYM; T5-75% RDN + 25% N through vermicompost; T6-50% RDN + 50% N through FYM, T7-50% RDN + 50% N through vermicompost; T8-25% RDN + 75% N through FYM; T9-25% RDN + 75% N through vermicompost and T10-100% RDN through chemical fertilizer (RDN). Application of 100% RDN + 25% N through vermicompost increased 207.36 and 215.79 percent nitrogen uptake by grain , 258.11 percent and 278.74 percent nitrogen uptake by straw, 307.17 and 332.26 percent higher phosphorus uptake by grain and 256.90 percent and 280.41 percent higher phosphorus uptake by straw and 288.08 and 319.69 percent higher potassium uptake by grain and 209.18 percent and 211.51 percent higher potassium uptake by straw of wheat with application of 100% RDN + 25% N through vermicompost over control treatment during both the consecutive years, respectively. Similarly application of 100% RDN + 25% N through FYM had 32.00 and 44.13 percent higher nitrogen, 86.77 and 144.26 percent higher phosphorus and 17.77 and 20.36 percent higher potassium over control treatment during both the consecutive years, respectively.
