Abstract:
A field experiment was carried out during the Kuruvai season of 2021 at Experimental Farm, Department of Agronomy, Annamalai University, and Annamalai Nagar in Tamil Nadu to examine the impact of Jeevamritham on growth, yield and nutrient uptake of ADT – 43 rice variety. The experiment was laid out in a randomized block design (RBD) with three replications with nine treatment comparing recommended dose of fertilizers along with foliar application of Amirthakaraisal @ 3%, Panchagavya, @ 3%, Vermiwash @ 6%, Fish amino acid @ 1%, Sea weed extract @ 0.5%, Humic acid @ 0.1%, Gibberellin acid @ 0.05%, and Jeevamritham @ 3%. Among the treatment tried out, T₈- RDF + Jeevamritham at 3% recorded the highest plant height (114.70 cm), number of tillers m^-2 (454.52), SPAD value, dry matter production, grain yield (5752 kg ha^-1), nutrient uptake (133.04 N,27.37 P,127.81 K kg ha^-1) and net income (Rs 51385 ha^-1). The least value was recorded in recommended dose of fertilizer application alone with plant height (80.62 cm), number of tillers m^-2 (368.16), SPAD value, dry matter production, grain yield (3715 kg ha^-1), nutrient uptake (98.21 N,19.21 P,105.20 K kg ha^-1) of NPK respectively and net income (Rs 21321 ha^-1).
