Abstract

Mentha is one of the predominant cash crops in India. However, it is a heavy feeder of nutrients. Organic sources of nutrients not only help in adequate nutrition but also maintain favorable physicochemical and biological soil environments. The present study was conducted to evaluate the response of different combinations of nutrients with microbial bio-fertilizer on mentha crops from 2020 to 2022. The experiment was carried out in the Randomized Complete Block Design with four replications and eight treatments viz; T1 - Control, T2 - RDF (N 75 kg ha-1, P2O5 20 kg ha-1), T3 - RDF + water soaking of roots, T4 - RDF + root soaking with bio-fertilizer, T5 - RDF + bio-fertilizer @ 10 kg ha-1, T6 - 100% N from FYM + water soaking of roots, T7 - 100% N from FYM + root soaking with bio-fertilizer and T8 - 100% N from FYM + bio-fertilizer @ 10 kg ha-1. The treatment T8 (100% N from FYM + bio-fertilizer @10 kg ha-1) significantly outperformed and recorded the highest growth and yield attributes viz; emergence count, stools count, plant height, leaf area index, leaf stem ratio, fresh and dry herb yield.
