Food and fodder shortage in arid and semi-arid regions force farmers to use marginal quality water for meeting water
requirement of crops which result in low quality, reduced production and adverse impact on soil properties. A field study on
loamy sand (Hyperthermic Typic Ustipsamments) saline soil was conducted during 1999–2001 at Central Institute for Research
on Buffaloes, Hisar. This involved assessment of effects of conjunctive use of saline water, EC¼4 6–7 4 dSm 1, SAR¼14–22
(mmol 1)½ with good quality water on five fodder crop rotations: oat-sorghum (Avena sativa-–Sorghum bicolor), rye
grass–sorghum (Loleum rigidum—Sorghum bicolor), Egyptian clover—sorghum (Trifoleum alexandrinum—Sorghum bicolor),
Persian clover—sorghum (Trifoleum resupinatum—Sorghum bicolor) and Indian clover–sorghum (Melilotus indica—
Sorghum bicolor) and certain soil properties associated with it. Leguminous winter fodder crops were more sensitive to poor
quality water use. Reductions in fodder yield with use of saline water alone throughout season were 85, 68, 54, 42, 36 and 26
per cent in Indian clover, Egyptian clover, Persian clover, oat, rye grass and sorghum respectively as compared to good quality
water. Leguminous fodder crops produced protein rich (12–14 per cent) and low fibre (18–20 per cent) fodder as compared to
poor quality grassy fodder under good quality water irrigation but their quality deteriorated when saline water was used. These
leguminous crops accumulated proportionately higher Naþ (1 58 per cent) resulting in adverse impact on their growth as
compared to grassy fodder crops.Higher soil salinity (12 2dSm 1), SAR¼20 (mmol 1)½was recordedwith salinewater irrigation;
and slight adverse impact was noticed on infiltration rate and contents of water dispersible clay. Alternate cyclic use of canal and
saline water could be an option for fodder production under such conditions. Copyright # 2006 John Wiley & Sons, Ltd.
