Abstract

A field trial was conducted on a sandy clay loam soil (Typic Haplustalf) at the Agricultural College and Research Institute, Madurai to study the influence of raw, partially decomposed and fully decomposed coirpith on the yield attributes and yield of rice (var.ADT 36). Both panicle length and grains per panicle were significantly increased by coirpith application. Twenty to twentyfive-day-composted coirpith (CCP) plots were on par with 30- day-CCP plots. Upto 20 cm depth, 30-day CCP plots recorded highest root length density but was on par with 25-day-CCP plots. Highest grain yield of 3.82 t ha recorded in 30-day CCP was on par with 25-and 20-day-CCP (3.79 and 3.75 t ha).
