  In this study, it is hypothesized that plants selected and/or bred for improved desired characteristics (e.g., macronutrients) may affect other characteristics (e.g., micronutrients) negatively. To test the hypothesis, we evaluated the metal micronutrient concentrations of four experimental strains viz., HighMgE, HighMgM, LowEq and LowMg and two commercial cultivars viz., Okamidori and Akimidori of orchardgrass. There were no genetic differences among the experimental strains/cultivars of orchardgrass for dry matter accumulation. The concentration of micronutrients varied with genetic differences among the four strains and the two commercial cultivars of orchardgrass. The amounts of Mn, Fe, Zn, Cu, Mo, Co, Ni, Se and I in the shoot, irrespective of strain or cultivars used, were 76.36, 74.83, 14.03, 9.36, 2.19, 5.00, 5.17, 2.00 and 19.33 μg g-1 at first harvest and 85.89, 74.56, 15.06, 12.30, 3.84, 6.14, 4.99, 2.54 and 19.53 μg g-1 at second harvest, respectively. The average amounts at the third harvest were 119.97, 90.36, 17.67, 13.39, 3.36, 4.56, 4.89, 2.36 and 20.06 μg g-1, respectively, whereas the corresponding amounts at the fourth harvest were 128.22, 156.00, 21.92, 10.31, 4.25, 4.53, 4.54, 1.47 and 28.72 μg g-1, respectively. Apart from few exceptions, Mn, Fe, Zn, Mo and I levels were highest in the fourth harvest, whereas the levels of Co and Se were highest in the second harvest. The level of Cu was the highest in the third harvest. The levels of Mn, Fe, Ni, Se and Mo were higher in low Mg containing plants irrespective of strain or cultivar. On the other hand, Co, Cu and I tended to peak in plants containing higher amounts of Mg. The Cu/Mo ratio was highest in the first harvest followed by the third, second and fourth harvests. The amounts of Mn, Fe, Ni, Co, Zn and Mo were within the optimum levels required for maintaining forage quality.

  The objectives of this study were to compare K, Ca and Mg utilization and grass tetany potential among the high and low magnesium containing strains and commercial cultivars of orchardgrass in response to application of dairy manure and chemical fertilizer. The study was conducted from 2002 through 2003 in northern Honshu Island, Japan on sandy loam Andisol. Highest plant dry matter production was recorded with the application of chemical fertilizer. Soil properties varied with application of manure. Potassium concentration in shoot tissue increased from 2002 to 2003 in all the treatments irrespective of strains and cultivars. However, calcium concentration in shoot tissue decreased from 2002 to 2003 in all the treatments irrespective of strains and cultivars. High magnesium containing strains almost showed low potassium and high magnesium and calcium concentrations in all the treatments. Concentrations of K, Ca and Mg in shoot tissue were highest as a result of dairy manure application and lowest by chemical fertilizer application. The grass tetany potentials were higher in 2003 than 2002. The grass tetany potential was lowest in all the cultivars and strains during fertilization with chemical fertilizer. High magnesium containing strains were less grass tetany prone than the others irrespective of treatments. The correlations between equivalent ratio and K were significantly positive; the correlations involving equivalent ratio, Ca and Mg were negative, however, regardless of treatments and years.
