Assessment of yield and economics of menthol mint (Mentha arvensis L.) with different biofertilizers and organics

Abstract

A field experiment was conducted to study the effect of different bioformulations and biofertilizers on yield and economics of menthol mint cultivation. The study revealed that the highest fresh herbage (34.50 t/ha), shade herbage (29.42 t/ha) and oil (290.87 kg/ha) yield were recorded in T11: (RDF) (150: 60: 60 NPK kg/ha and FYM-10 t/ha) + panchagavya (3%) + amritpani (3%) + humic acid (0.2%) + Arbuscular mycorrhiza fungus (Glomus intraradices), Azotobacter chroococcum + Azospirillum brasilense + Phosphorous solubilizing bacteria (PSB). While, lowest fresh herbage (15.69 t/ha), shade herbage (12.45 t/ha) and oil (98.61 kg/ha) yield were noticed in T1 (control): RDF (150: 60: 60 NPK kg/ha and FYM-10 t/ha). Maximum gross returns (Rs 3,63,591), net returns (Rs 2,80,168) and benefit: cost ratio (3.36) were recorded in T11 whereas, minimum benefit: cost ratio was recorded in T1 (control).
