Abstract
A field experiment was conducted to study the effect of organic nutrients and bio fertilizers on soil parameters and nutritional content of amaranth. Eleven treatments were taken in three replications and the experiment was conducted in a randomized block design (RBD).The treatments were T1:RDF (60:30:20 kg NPK/ha), T2:Vermicompost @ 2 t/ha, T3:Vermicompost @ 5 t/ha, T4:FYM 10 t/ha, T5:FYM 20t/ha, T6:Poultry manure 3t/ha, T7:Poultry manure 5 t/ha, T8:Vermicompost @ 2 t/ha+PSB+Azospirillum@ 5 kg/ha each, T9 :FYM @ 10t/ha+ PSB+Azospirillum@ 5 kg/ha each, T10:Poultry manure 3 t/ha+ PSB+Azospirillum@ 5 kg/ha each and T11: Untreated control. The highest vitamin C (147.8 mg/100 gm) and crude fibre content (1.48%) was observed in the treatment T8 and T4, respectively. Maximum calcium (8.36%) and iron (0.21%) content was observed in the treatment T8. The treatment T10 recorded the highest mean performance for PH, organic carbon, available nitrogen and potash content in the soil analyzed after harvest of the crop.
