Grain Yield Responses
The yield at 14% moisture content of the Nangdam
variety had the grain yield of 29.12 kg/ha, which was not
significantly different from those of Lebnok variety
which gave the grain yield of 26.20 kg/ha. The grain per
panicle was not significantly different among the
varieties. The Nangdam and Lebnok varieties had the
grain per panicle of 161.00 and 146.00 grain,
respectively. Both varieties of upland rice had the
highest number of empty grain of 48.00 and 33.00 grain
per panicle, respectively (Fig. 2b), number of low
perfect grain of 53.00 and 57.00 grain respectively,
number of high imperfect grain of 35.00 and 30.00 grain
per panicle, respectively. percentage of high chalky grain
of 17.50 and 15.20%, respectively and breaking grain of
0.75 and 2.50%, respectively, which were not
significantly different among the varieties (Fig. 3a).
Grain sizes (Fig. 3b) of the two varieties were
measured in width, length and thick. It was found that
Nangdam and Lebnok varieties were not significantly
different among the varieties. Nangdam and Lebnok
varieties had grain width, length and thick of 1.07 and
0.97, 2.48 and 2.01 and 1.87 and 1.75 mm,
respectively. As for the 1,000 grain weight (Fig. 3b),
Nangdam and Lebnok varieties had 1,000 grains
weight of 18.91 and 18.67g, respectively, which were
not significantly different among the varieties
