ABSTRACT
In order to evaluate the effects of organic and inorganic sources which enhancing the growth and yield of rice. The field experiment was conducted in farmer’s field at Varagurpettai Village, Chidambaram (TK), Cuddalore (DT). The experiment with factorial randomized block design with three replications usingrice variety ASD-16 in the season’s kharif 2022. The treatment details namely,two factors F & S. F0 - Control, F1- 50 % RDF, F2 - 100% RDF, F3 -150% RDF, S0 - Control, S1 -Vermicompost@ 5 t ha-1, S2-Press mud @ 5 t ha-1, S3-Green leaf manures @ 6.25 t ha-1, S4- Poultry manure @ 5 t ha-1. The initial pH and EC of the soil status was registered 7.9 and 1.7 d Sm-1. The initial status of available N (137 kg ha-1), P (8.6 kg ha-1) and K (175 kg ha-1) was recorded. The micronutrients such as DTPA-Zn, Fe, Cu and Mn content of the soil which recorded 0.64, 12.2, 0.48 and 9.1 mg kg-1. The results showed that growth, yield and yield attributes of rice wassuperiorly increasedby the application of 100% RDF(F2) with S4 -Poultry manure at 5 t ha-1 compare to control (FoSo).
