A trial at farmers field was conducted during rabi season at different villages in Ramgarh district of Jharkhand to study the effect of different types of mulching on growth and yield of chilli for two consecutive years 2019-2020 and 2020-2021, Mulching materials i.e. plastic mulch (double coated silver-black 30 micron), bio mulch (paddy straw) and no mulch (control) for chilli farming were taken for the study. The trial was laid out in randomized block design (RBD) with three treatments and eight replications. Data was recorded for weed population or weed density (m³), soil moisture content, plant height, fruit weight, fruit numbers, number of structural branches, fruit length, number of leaves per plant, fruit yield/ plant (kg), fruit yield/ ha (q), days to flowering, days to first picking and fruiting span. Economics of various treatments were also worked out and BC ratio was calculated. The results revealed that plastic mulch (double coated) recorded the highest soil moisture retention (15.06 %), lowest weed population/ weed density (74.81), highest plant height (88.17 cm), maximum number of fruits/ plant (217.27), fruit length (8.66 cm) and fruit weight (9.99 g). Maximum number of leaves per plant (595.50) was also found with plastic mulch. Fruit yield/ plant (1.42 kg) and total fruit yield/ ha (463.08 q) with high cost benefit ratio (2.80) were recorded highest in plastic mulch followed by bio mulch and found lowest in plant with no mulch. Lowest soil moisture content (10.86 %), highest weed population (160 m2), minimum yield/ ha (134.0 q) and lowest benefit cost ratio (1.37) were recorded from without mulched plot. Therefore, mulching (organic as well as plastic) appears to be a viable tool to increase the chilli production and recommended for cultivation.
