Effect of boronated saline irrigation water on linseed

Extract
Underground irrigation water, particularly saline, when in arid and semi-arid regions of India may contain toxic amounts of B, from a trace up to 10 mg B/l (Anon. 1981–82). Continuous use of such water for irrigation may lead to the accumulation of salts and B in soil and this creates toxicity problems. Kanwar & Mehta (1970) have reported that water containing 2 mg B/l is hazardous if used on heavy soils. For sandy loam soils of semi-arid tracts in India, Chauhan & Powar (1978) have reported reductions in the grain yield of wheat and pea at 4 and 6 mg B/l respectively, while under similar conditions grain yield of lentil and barley was reduced at 3 and 6 mg B/l respectively (Chauhan & Asthana, 1981). So far, few attempts have been made to evaluate the effect of boronated saline water on soil and crops, under different agroclimatic conditions. A study of the effect of boronated saline water on an important oil-seed crop, linseed, on alkaline sandy loam soil in the semi-arid region of Agra, India was therefore undertaken.
