Effect of organic inputs and mulching on growth and yield of roselle (Hibiscus sabdariffavar. sabdariffa)

A field experiment was carried out on a farmer’s field at Kannitamilnadu village in Cuddalore district, Tamilnadu during 2018 to find out the suitable organic inputs and pattern of mulching for better growth and yield of roselle (Hibiscus sabdariffavar. sabdariffa). The experiment was laid out in a factorial randomized block design with five levels of organic manures and four levels of mulching with three replication.. Best of the interaction effect was due to the combined application of 25 t FYM + 3 t poultry manure ha-1+ plastic mulch (M3S2) which recorded the highest values for all growth and yield parameters viz., plant height (228.3 cm), number of branches (14.5), leaf area (308.9 cm2), number of calcyes/plant (33.5), calyx yield/plant (233.9 g) and calyx yield/ha (6568.75 kg). The lowest values of these parameters were recorded under control (no organics and no mulching) treatment
