Abstract
Setaria italica <L> ., an important minor millet is
grown extensively in the semi-arid regions of India on
account of its drought resistance under rainfed conditions.
Nutrient treatment with Cobalt, Copper, Molybdenum and Zinc
was undertaken to know the influence of these nutrient
elements on drought resistance in Korra cv Arjuna during the
rabi season( November 1988-February 1989 >.
Treatment with Co, Cu, Mo and Zn improved the crop
growth in terms of plant height, leaf dry weight, stem dry
weight, total dry weight and grain yield. CSR, LAR, LWR, LAI leaf area and flag leaf area were also increased by these
elements.
