Description A field experiment was conducted during 2004-2005 to study the
effect of sodic water irrigation depth (4, 5 and 6 cm through sprinkler
system) and gypsum levels [G0, G50, G75 and G100 per cent neutralization
of RSC (12.0 me l-1) with gypsum] on wheat and soil properties. This
experiment was initiated in 2002 on Regional Research Station of CCS
Haryana Agricultural University at Bawal (Rewari).
Increased volume of sodic water and gypsum levels significantly
influenced the growth parameters. The data indicated that grain yield of
wheat under 4, 5 and 6 cm irrigation depth with sodic water through
sprinkler was 34.27, 36.90 and 39.0 q ha-1 and with gypsum level G0, G50,
G75 and G100 per cent neutralization of RSC was 34.07, 36.28, 37.87 and
-XVI-
38.69 q ha-1, respectively. The increase in rain yield due to 6 cm irrigation
depth over 4 and 5 cm was 13.8 and 5.7 per cent, respectively.
Neutralization of RSC with gypsum decreased Na : Ca and Na : K ratio in
plants. Similar results were also obtained in case of straw yield of wheat.
The one of the most mimportant finding indicated that neutralization of RSC
upto 75 per cent with gypsum was found at par with 100 per cent
neutralization thereby indicating that under sprinkler system 75 per cent
neutralization of RSC is sufficient. Application of gypsum increased the
contents of N, P, K, Ca, Mg and S while Na content was decreased in grain
and straw of wheat.
Relatively higher pH and ESP were observed in soil under 5 and 6 cm
as compared to 4 cm depth of irrigation. Soil pH and ESP decreased with
increasing level of gypsum irrespective of depth of irrigation. The content of
pH, EC, ESP and CaCO3 was increased with increasing soil depth and
irrigation depth and decreased with increasing level of gypsum, while
organic carbon was decreased with increasing soil depth.
The results revealed that the hydraulic conductivity and infiltration
rate of the soil increased with increasing gypsum levels but decreased with
the increasing irrigation depth. The hydraulic conductivity and infiltration
rate was increased by 115 and 363 per cent, respectively with the
application of G100 as compared to G0 levels. The dispersion ratio and soil
strength however showed an increasing trend with increasing irrigation
depth but decreased with levels of gypsum.
