Productivity, soil fertility and economic indicators in Centella asiatica L. production systems in semi-arid India

Le résumé fourni par la source

Centella asiatica L. urban is one of the highly traded medicinal crops in the global market and it is collected mainly from wild sources/forests. The scope for commercial cultivation of elite genotypes of C. asiatica at different nutrient levels was assessed based on resource use and economic indicators in open-field and 50% shade in India during 2016–2019. The cumulative productivity in terms of fresh biomass was significantly influenced by genotypes and nutrient levels both in open-field and 50% shade. The genotype Arka Divya genotype was superior in terms of cumulative productivity per ha (38.5 t in open-field and 33.9 t in 50% shade). Application of farmyard manure (FYM) 5 t + 125 kg nitrogen (N) through FYM registered higher cumulative yield in open (32.2 t ha−1) and 50% shade (33.1 t ha−1). The production systems in open and 50% shade maintained optimum to above optimum soil fertility and plant nutrient profile. The net return per rupee investment was higher in Arka Divya genotype at different nutrient levels in open-field (2.61–3.69) as well as 50% shade conditions (1.38–1.96). Integrated application of recommended dose of major nutrients and FYM registered higher net return per rupee investment both in open-field (3.69) and 50% shade (1.96). The elite genotypes of C. asiatica can be grown profitably in open-field or 50% shade with provision of optimum nutrition. Alternatively it can be grown as intercrop in perennial fruit or plantation crops with provision of irrigation to reduce production cost.
