Abstract: The present investigation entitled “Effect of age of seedlings on aromatic rice (Oryza sativa L.) varieties under system of rice intensification.” was conducted at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India during rainy (Kharif) season of 2015 with a view to test the comparative performance of different varieties and age of seedlings on the performance of aromatic rice under eastern Uttar Pradesh condition to suggest better selection of aromatic rice cultivar with proper seedling ages under system of transplanting. Factorial experiment was laid out in Randomized Complete Block Design with three levels of varieties viz. Kalanamak, Adamchini and Badshahbhog and four levels of age of seedlings i.e. 10-day, 14-day and 18-day under SRI and 21-day under standard management practice (SMP) as a control with replicated thrice. These aromatic rice varieties were grown as a test crop. Various observations were recorded during the course of investigation including growth parameters, yield attributes and yields as affected by varieties and age of seedlings. Growth parameters were recorded at at 30 DAT followed by 60, 90, 120 DAT and at harvest which included plant height, number of tillers hill-1, dry matter accumulation hill-1, leaf-area index and chlorophyll content and some phenological observation like 50% flowering and 50% physiological maturity. Similarly yield attributes viz., panicle length, panicle weight, number of panicles m-2, grains panicle-1, unfilled spikelets panicle-1 and 1000-grain weight, grain and straw yield and total removal of the nutrients (NPK) were also noted to assess the effect of treatments. Besides, protein content and protein yield in grain was also estimated. Among the aromatic varieties, ‘Badshahbhog’ responded favorably superior but ‘Adamchini’ was an alternate option for selection of aromatic rice cultivar under SRI with for achieving higher yield at Varanasi. The 14-day old seedling exhibited for enhancing productivity of aromatic rice under SRI. Transplanting of ‘Badshahbhog’ aromatic rice with 14-day old seedling under SRI proved most remunerative for achieving higher net return.
