Intercropping of medicinal plants with cassava (Manihot esculenta Crantz) under different row arrangements

Abstract


A field experiment was conducted during the period from September 2020 to March 2021 at the Department of Agronomy, College of Agriculture, Vellanikkara, to assess the feasibility of intercropping medicinal plants in cassava. Intercropping significantly influenced the growth and yield attributes of both main and intercrops. Shorter cassava plants were observed when Sida alnifolia was intercropped as double row (162.84 cm). In general, medicinal plants grown under intercropping system recorded taller plants, except for Indigofera, where sole cropping resulted in taller plants. The sole crop of cassava produced higher per plant tuber yield of 3.24kg and was at par with cassava with single row of Plectranthus (3.12 kg/plant). The lowest tuber yield was recorded when cassava was intercropped with double row of Sida (1.77 kg/plant). The yield of medicinal plants was the highest in sole cropping, followed by single row intercropping and double row intercropping. Same trend was observed for quality parameters of medicinal plants, where higher values of the phytochemical constituents were recorded in sole crops. medicinal plants.
