Author(s): U Nagabhushanam and P Spandana Bhatt
Abstract: A field experiment was conducted to study the “Effect of sowing dates and nutrient management practices on yield, nutrient uptake and economics of rice (Oryza sativa L.) During Kharif, 2017 at Rice research Centre, Agricultural Research Institute, Rajendranagar, Hyderabad (TS), India. The experiment was laid out in split plot design with four replications, comprises three main plot treatments i.e., sowing dates M1- Normal sowing- first fortnight of July, M2- 15 days after normal sowing (Late sowing) second fortnight of July, M3- 30 days after normal sowing (Very late sowing) second fort night of August, six sub plot treatments i.e., S1- 100% RDF(RDF+Zn) (N-3 splits@1/3+1/3+1/3), S2- 100% RDF( RDF+Zn) (N-3 splits@1/2+1/4+1/4), S3- 150% RDF (RDF+Zn) (N-3 splits@1/3+1/3+1/3), S4- 150% RDF (RDF+Zn) (N-3 splits@1/2+1/4+1/4), S5- 100% NKZn+150% P (N-3 splits@1/3+1/3+1/3), S6- Absolute control (no fertilizers). The results revealed that normal, late sowings were found to be optimum with 100% RDF(RDF+Zn) (N-3 splits@1/3+1/3+1/3), proved to be better for obtaining maximum grain yield and net returns.
