Abstract
Field experiment was carried out at wetland of Tamil Nadu Agricultural University, Coimbatore
during Kharif 2008. The experiment was laid out in a factorial randomized block design with
three replications to evaluate the stand establishment techniques and nutrient management
practices in wet seeded lowland rice. The treatments consisting of two establishment
techniques (Direct planting system and drum seeding) and four levels of nutrient management
practices (control, RDF, RDF+FYM and RDF+FYM+Biofertilizers). Direct planting system recorded
higher yield components and grain yield compared to drum seeding method of crop
establishment. Application of recommended dose of fertilizers (150:50:50 NPK kg ha -1 ), FYM
12.5 t ha -1 and biofertilizers (Azosphosmet @ 2 kg ha -1 ) + PPFM (pink pigmented facultative
methylotroph) @ 5 L ha -1 enhanced the grain yield over no manure treatment under Direct
Planting System when compared with drum seeding method. The net income and B:C were
higher under DPS than drum seeding method due to higher grain yield.
