Effect of nitrogen, phosphorus and potassium (NPK) application at various doses on yield of early transplanted rice

Abstract

Field experiment was carried out to assess the influence of various levels of NPK fertilizers (F1: 50-30-20 & F2: 100-60-40 kg/ha) on yield 5 new rice cultures namely IET 26767, IET 26803, IET 26477, IET 24914, IET 25713 and 4 national checks (Sahbhagi, Varalu, NDR 97 and Govind) and one local check (Shushk Smart) in split plot design with three replications at Crop Research Station, (ANDUAT), Masodha, Ayodhya. Results revealed that application of the highest grain yield was recorded with IET 25713 (4.87 t/ha). At higher level of RDF i.e. 150% followed by IET 26477 (4.55 t/ha). The increase level of NPK increase up to (150% RDF). The highest grain yield was recorded at 150% RDF/ha (3.84 t/ha). The lowest grain yield was recorded with recommended level of RDF (100%/ha) (3.69 t/ha). Shabhagi dhan recorded lower mean grain yield of RDF and higher level of RDF.
