Abstract
The efficiency of different reclaments on the reclamation of saline-sodic non-gypsiferous soil was studied. The treatments tried were: i. control, ii. gypsum @ 50% GR, iii. grosum @ 50% GR+ 50 tons ha"1 FYM. iv. H2S04 eq. to 1/10 OR of soil, v. H2S04 eq. to 1/10 GR+50 tons ha"1 FYM. Gypsum was mixed in the upper 15cm soil layer by ploughing whereas H2SO4 was applied with irrigation water. Rice-wheat crop rotation was followed from 1984 to 1988 with recommended dose of fertilizers. Reclamation of 0-30 cm depth was almost completed in treated plots on completion of first year of crop rotation. ECe of the upper 90cm soil was brought within safe limits after the first rice crop but SAR was lowered to safe limits after the third rice crop for all treatments except control. Maximum paddy and wheat grain yield was obtained with the combination of 50% gypsum and 50 tonsha FYM. It was followed by M2SO4 eq., to 1/10 gypsum requirement (GR) when combined with 50 tons ha FYM.
