Abstract

A field experiment was conducted to study the effect of various organic wastes based vermicompost on physiological growth of rice (Oryza sativa L.) during the year 2019-20 and 2021. The experiment was carried out at the Wetland farms, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu. The study was carried out with various organic wastes based vermicompost. The treatments includes the earthworm Eudrillus eugeniae species with organic wastes paddy straw (T1), coconut wastes (T2), vegetable wastes (T3), farm wastes (T4) and FYM (T5) and Eisenia foetida with paddy straw (T6), coconut wastes (T7), vegetable wastes (T8), farm wastes (T9) and FYM (T10) and absolute control (T11). The result showed that the treatment Eudrillus eugeniae + coconut wastes (T2) was found significantly superior on drymatter production and other physiological growth rates during both the years. The study revealed that the vermicompost from coconut wastes along with earthworm species Eudrillus eugeniae infl
