The use of organic and inorganic mulch as a soil cover is effective in improving growth and yield of chilli (Capsicum annuum L.). A field experiment was carried out at College Orchard, Department of Vegetable Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during 2013 to 2016 to study the effect of different types of mulches viz., organic mulch @ 6.0 t/ha, organic mulch @ 9.0 t/ha, organic mulch @ 12.0 t/ha, black / silver polythene (double coated 30 micron), black / white polythene (double coated 30 micron) with a control on growth and yield of chilli. The experiment was laid out in Randomized Block Design (RBD) with six treatments and replicated four times. The results revealed that organic mulch @ 12.0 t/ha (T4) recorded the highest plant height (88.17 cm), number of fruits/plant (217.27) with an average fruit weight of 4.67 g, fruit length (8.66 cm), fruit girth (1.96 cm), green fruit yield (0.939 kg/plant and 325.93 q/ha), dry fruit yield (0.226 kg/plant and 75.98 q/ha) followed by black/white polythene double coated 30 micron (T6) which recorded 210.20 number of fruits/plant with an average fruit weight of 4.61 g and low weed density (13.23/m2) at 75 days after planting with high cost benefit ratio (2.80). Therefore, mulching (organic as well as black/white polythene (double coated 30 micron) appears to be a viable tool to increase the chilli production and recommended for cultivation.
