Abstract
Five presowing seed treatments were given to seed and nursery of IR-6 and transplanted into glazed pots having four levels of salinity Le., EC 1.6, 5, 10 and 15 dS m- , produced by adding Nae S04' NaCI, CaCl2 and MgS04 in the ratio of 9:7:3:f respectively.There was a significant reduction in plant height, tillering, grains per panicle, paddy and straw yields with increasing salinity. Grain yield was more affected than the straw yield. Presowing seed treatments increased significantly the tillering capacity, grains per panicle, 1000-grain weight, paddy and straw yields. Maximum increase was found in..I T1 i.e, CaS04• 2H2 0 application @0.15 t acre -1 3" to nursery after soaking the seed in 20 me 1 CaS04.2H2 0 for four hours.
