Abstract
Field experiments were conducted during the kharif [monsoon] and rabi [winter] seasons of 1975-8 to study the effects of saline water applied by sprinkler and surface methods of irrigation on the performance of bajra [Pennisetum americanum] and wheat crops and salt accumulation in soil. Saline water of 11 mmho/cm EC applied by sprinkler reduced bajra yield by 33%, but that of wheat by only 3%. Saline water up to 6 mmho/cm EC was safe for bajra if applied by sprinkler in late evening or at night. The marked reduction in bajra yield with application of 11 mmho/cm EC water by sprinkler was mainly due to burning of leaves caused by excessive Na content in the water. This water did not cause damage to the same extent to wheat because of lower temp. and higher RH prevailing in the rabi season than in the kharif season. In sprinkler irrigated plots, the salt accumulation in the soil profile (0-120 cm) was 30-40% less than with surface irrigation
