Boron Requirements of Maize with differnt SAR Waters

Availability of good quality irrigation water in sufficient quantities is becoming serious threat to world crop production.Several soil, plant and climatic factors influence B availability and uptake by crops.Farmers generally apply ground water of different SAR. Therefore it is a strong need to assess the changing B requirement with changing SAR. The objective of this research was to determine the internal and external requirements of B for maize cultivar grown on an alkaline calcareous soil when irrigated with different SAR levels to check its sufficiency range.
