Abstract: Experiments were carried out during May - September 2019 and 2020, to assess the effect of growing condition and mulching on root yield and quality of Plectranthus vettiveroides. Experimental design was split plot with three main plots (open, 25 per cent shade and 50 per cent shade) and three sub plots (no mulching, organic mulching with paddy straw and black polythene mulching). Higher bio mass yields were recorded under open and 25 per cent shaded condition (9763 and 9576 kg ha-1 respectively), which were statistically on par. Among sub plot treatments, mulching with the black polythene sheet was the best with respect to fresh biomass yield followed by organic mulching. Root yield and essential oil content also showed a same trend of biomass yield with higher root yield and oil content under 25 per cent shaded condition (1370 kg ha-1 and 1.84 per cent) followed by open condition (1285 kg ha-1 and 1.80 per cent), which were on par.
