Abstract : A study was conducted at the Department of Seed Science and Technology, Tamilnadu Agricultural University,
Coimbatore in June - July season of two different years to find out suitable organics for enhanced productivity
of rice cv ADT 43 for organic seed production. The results revealed among the organic soil application of neem
cake (1786 kg ha-1) along with 3 per cent panchakavya foliar spray maximized the yield along with yield attributing
characters (plant height, total number of tillers hill-1, productive tillers hill-1, chlorophyll content, panicle length) and
resultant organic seed quality characters. However, the yield was higher with basal nutrients applied as inorganic
(3537 kg ha-1 in initial and 4352 kg ha-1 in confirmation), which was on par with neem cake + panchakavya (3500 kg
ha-1 in initial and 4315 kg ha-1 in confirmation), GLM + azolla (3380 kg ha-1 in initial) and GLM + azolla +
panchakavya (4213 kg ha-1 in confirmation) treatments and sprayed with panchakavya at vegetative, flowering and
maturity. These findings are highly useful for paddy organic seed production programme.
