Influence of biochar and farmyard manure on growth performance and economic returns of soybean (Glycine max L. Merrill)

Abstract

The field experiment was conducted during kharif season of the year 2024-2025 at Central Farm, College of Agriculture, VNMKV, Parbhani to assess the influence of Biochar and Farmyard Manure on growth performance and economic returns of soybean (Glycine max L. Merrill). The experiment was laid out in Randomized Block Design with three replications and ten treatments. The treatments were T1: Control, T2: 100% RDF, T3: 75% RDF + 2 t ha-1 Biochar, T4: 75% RDF + 1 t ha-1 Biochar, T5: 75% RDF + 2 t ha-1 Biochar + 5 t ha-1 FYM, T6: 75% RDF + 1 t ha-1 Biochar + 2.5 t ha-1 FYM, T7: 100% RDF + 2 t ha-1 Biochar, T8: 100% RDF + 1 t ha-1 Biochar, T9: 100% RDF + 2 t ha-1 Biochar + 5 t ha-1 FYM, T10: 100% RDF + 1 t ha-1 Biochar + 2.5 t ha-1 FYM. On the basis of present investigation, the results revealed that the application of 100% RDF + 2 t ha-1 Biochar + 5 t ha-1 FYM (T9) improved crop growth performance with higher gross and net monetary returns and it was at par with the application of 100% RDF + 1 t ha-1 Biochar + 2.5 t ha-1 FYM (T10) and 75% RDF + 2 t ha-1 Biochar + 5 t ha-1 FYM (T5) and found significantly superior over rest of the treatments.
