Abstract
Field experiment was conducted at Annamalai University Experimental Farm, Annamalai Nagar, Tamil Nadu, India during Kharif Season (June to September, 2013) to study the effect of age of seedlings and spacing on nutrient uptake and post harvest soil available nutrients in transplanted kodo millet. The treatments comprised three ages of seedlings (20, 25 and 30 days) and four spacing (Farmer practice of direct sowing, 15 x 10, 20 x 10 and 25 x 10 cm). The experiment was laid out in randomized block design with factorial arrangements and replicated thrice. Among the three ages of seedlings and four spacing, 20 days old seedlings and spacing of 15 x 10 cm recorded higher NPK uptake in kodomillet. The combined effect of age of seedlings and spacing, 20 days old seedlings planted at 15 x 10 cm registered its superiority over others for nutrient uptake in kodo millet. Regards to post harvest soil available nutrients, the higher soil nutrients availability was noticed with 30 days old seedlings, similarly direct sowing recorded maximum soil available nutrients. The same treatment combination registered higher NPK availability in the soil.
