Description A study was conducted at the International Crops Research Institute for the Semi-
Arid Tropics (ICRISAT), Patancheru, Andhra Pradesh, India to compare grain Zn
and Fe determined in ground and un-ground samples of a range of sorghum and
pearl millet cultivars varying in grain size. The 1000 grain weight of pearl millet
samples ranged between 4.7 and 9.4 g for the small grain cultivars, whereas for the
bold grain cultivars it ranged from 10.0 to 13.0 g. In sorghum, the grain size ranged
between 9.6 and 19.3 g for the small grain cultivars and ranged from 26.9 to 46.4 g
for the bold grain cultivars.
Grain Fe in pearl millet cultivars determined using ground samples ranged from 26.6
to 81.5 mg kg'' and it ranged from 26.5 to 81.7 mg kgs' when determined with unground
samples. Grain Zn ranged from 18.7 to 73.7 mg kg" for ground and from
19.5 to 72.1 mg kg" for the un-ground samples. The analysis of variance indicated a
significant difference in grain Fe due to grain size for the ground and un-ground
pearl millet samples. However, there was no significant difference in grain Zn due to
grain size between ground and un-ground samples.
For sorghum, grain Fe varied from 18.2 to 65.1 mg kg-' in ground samples and from
19.0 to 65.0 mg kg-' in un-ground samples. Grain Zn ranged from 16.9 to 61.0 mg
kg-' in ground and from 16.5 to 6 1.0 mg kg" in un-ground samples. There was no
significant difference due to grain size between ground and un-ground samples for
both Fe and Zn.
There was a significant correlation between grain Fe and Zn values determined
using ground and un-ground pearl millet and sorghum cultivars. The results of this
study with selected but diverse cultivars suggest that grain Fe and Zn in sorghum
and pearl millet can be determined on un-ground samples and obviously there is a
need to further confirm these results with a larger number of cultivars of these crops.
