An experiment was carried out during the rainy (kharif) season 2013, to study the effect of inorganic and or- ganic sources of nutrients on plant growth, productivity and economics of basmati rice in rice (Oryza sativa L.) wheat [Triticum aestivum (L.) emend. Fiori & Paol.] cropping system at Meerut, Uttar Pradesh. Ten treatments con- sisting of control (N P K ), 100% recommended dose of fertilizers (RDF) (120 : 60 : 60 NPK kg/ha) and 125% 0 0 0 RDF were studied against combination of organic manures with chemical fertilizers, i.e. 50% RDF + vermin-com- post (VC) @ 3.82 t/ha, 50% RDF + farm yard manure (FYM) @ 11.71 t/ha, 50% RDF + poultry manure (PM) @ 1.85 t/ha, 50% RDF + VC (@ 1.91 t/ha) + FYM (@ 5.85 t/ha), 50% RDF + VC (@ 1.91 t/ha) + PM (@ 0.97 t/ha), 50% RDF + FYM (@ 5.85 t/ha) + PM (@ 0.97 t/ha) and 50% RDF + FYM (@ 3.90 t/ha) + PM (0.65 t/ha) + VC (@ 1.32 t/ha), in randomize block design with 3 replications. Highest plant height, tillers, dry matter, yield attributes and grain yield (4.56 t/ha) of Basmati rice were recorded with the application of 125% RDF through inorganic source of nutrients which was statistically at par with the treatment of 50% RDF + poultry manure (4.28 t/ha) and significantly higher than 100% RDF (3.84 t/ha) and the control. Among different combination of organic manures with inorganic sources of nutrients, the replacement of 50% RDF with poultry manure recorded in significantly higher yield attributes and yield along with higher net returns and benefit: cost ratio.References
