Organic seedling production in paddy

The field experiment was conducted in two seasons’ kharif 2013 and kharif 2014 in the farmers’ organic field at Neer Manvi, Manvi Taluk, Raichur District, Karnataka, India. With a view to know the influence of organic nutrients on growth, development and root ATPase activity of paddy seedlings. Experiment was laid down in RBD design with three replications and 13 treatments. Among the treatments, inorganic treatment (RDF) recorded significantly highest mean shoot length (15.35 and 20.29 cm), chlorophyll content (25.09 and 33.20 SPAD value), dry matter production (0.489 and 0.617 g seedlings-10) and number of thrips (5.20 and 4.25) at 20 and 25 Days after sowing (DAS), respectively. Whereas, maximum mean root length (10.10 and 17.03 cm), root volume (1.007 and 1.123 cc seedling –1) and root ATPase activity (0.900 and 1.200  mol pi g-1h-1) was recorded at 20 and 25 DAS, respectively in organic treatment i.e. application of 50 % FYM + 50 % VC + panchagavya @ 3 %. From this study, it is concluded that for organic seedling production application of 50 % FYM + 50 % VC + foliar spray of panchagavya @ 3 % on 12th and 18th DAS found better in paddy.
