Effect of Age of Seedling and Time of Nitrogen Application on Yield Attributes and Yield of Rice (Oryza sativa L.) under Mechanized Rice Intensification System (SRI)

摘要

A field experiment was conducted during kharif 2013 at ZARS, V.C. Farm, Mandya to standardize age of seedlings and time of nitrogen application for mechanized SRI. The result revealed that mechanical transplanting of 15 days old seedlings with N application in four splits at basal, top dressing at 30, 60 and 75 days after transplanting and application of pre mixture of Bensulfuron methyl and Pretilachlor at three days after transplanting followed by one time conoweeding at 25 DAT significantly influenced yield parameters and grain yield of hybrid rice as compared to other treatments.
