A field experiment was taken under to study the effect of variations in shade levels, time of planting and mulching on yield and quality of Kiriyath (Andrographis paniculata). The treatments consisted of two shade levels (open and 50 per cent shade), four dates of planting (15th May, 15th June, 15th July and 15thAugust), and three mulching practices (no mulching, paddy straw mulching and black polythene mulching). Higher biomass yield was obtained when planted on 15th May under shade with black polythene mulching (15.67 t ha-1). However, it was on par with June planting with black polythene mulch under shaded condition (14.33 t ha-1). Andrographolide, the major secondary metabolite responsible for the medicinal property, was higher when planting was in July under shade with paddy straw mulching (1.17%) and was on par with August planting with paddy straw mulching under shade (1.14%).Downloads
