The 3-year study at Bengaluru, India assessed the effects of genotypes and nutrient levels on resource use parameters in Centella asiatica production systems in open-field and 50% shade to develop economically viable production package. The biomass accumulation pattern indicated that there were year wise variations in biomass accumulation in open-field and 50% shade conditions, but cumulative dry biomass was similar in both production systems. The genotype Arka Divya showed consistent growth performance in both open-field and 50% shade conditions, but Arka Prabhavi performed better in 50% shade. Different nutrient levels showed similar trend on cumulative dry biomass in open-field as well as in 50% shade. The total yield of identified bioactive compounds was higher in open field (141.2 kg ha(-1)) than in 50% shade condition (110.5 kg ha(-1)) in second year. Similarly, asiaticoside yields were 22% higher in open-field over 50% shade condition. Genotypic variations were significant with respect to content and yield of bioactive compounds in both open-field and 50% shade. At higher nutrient level of Farm yard manure (FYM) 5 t + 125 kg N through FYM, the yield of bioactive compounds was significantly higher in open-field (193.0 kg yield of active compounds ha(-1)) than in 50% shade (165.6 kg yield of active compounds ha(-1)). The uptake of macronutrients was significantly higher in 50% shade than in open-field. The results highlight that C. asiatica can be grown both in full sunlight and 50% shade along with optimum nutrition, but open-field cultivation of C. asiatica would be profitable.
