Nutrient management in bengal aromatic rice of terai-teesta alluvial zone in west bengal

A field experiment was conducted during kharif season of 2018–19 and 2019–20 at Jalpaiguri district of West Bengal to study the effect of combination of organic and inorganic sources of nutrients in aromatic rice variety Kalonunia production. The experiment consisted of three treatments comprising of farmers’ practice i.e., imbalanced use of fertilizers (30 kg N/ha + 20 kg P₂O₅/ha + 20 Kg K₂O/ha), T1; 80% RDN (RDF-50:25:25 Kg/ha) through inorganic source + 20% N through organic Sources (FYM and mustard cake), T2: 60% RDN (RDF- 50:25:25 Kg/ha) through inorganic source + 40% N through organic sources (FYM and mustard cake).The results indicated that, application of 60% RDN through inorganic source + 40% N through organic sources gave maximum grain yield (2.48 t/ha) and straw yield (6.62 t/ha). and recorded significantly higher growth parameters and yield attributes whereas lowest observation was with famers’ practice.
