Effect of age of seedlings and planting geometry on growth of rice (Oryza sativa L.)

The present investigation entitled was conducted at Agronomy Research Farm, Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during Kharif season of 2019. The experiment was laid out in split plot design with three replications keeping three age of seedlings viz., three weeks old seedlings, four weeks old seedlings and five weeks old seedlings in main plots and four planting geometries 20 cm x 10 cm, 25 cm x 10 cm, 20 cm x 15 cm and 25 cm x 15 cm in sub plots. Result revealed that there was significant variation among different time of transplanting in respect of growth. Growth parameters as plant height (cm), number of tiller (m-2), dry matter accumulation (g) and leaf area index were higher in paddy transplanted in three weeks old seedlings as compared to rest of the age of seedlings. Planting geometry of 20 cm x 10 cm was recorded superior in respect of growth over rest of the planting geometry.
