Abstract
The present investigation was carried to study the effect of nitrogen levels. hill
spacing and rice cultivar mixture on some rice characters. Where used. three nitrogen
levels (40, 60 and 80 kg N/fed.); three hill spacing (1J x 20, 15 x 20 and 20 x 20 cm),
combined with five rice cultivar mixtures (25% Giza 177 with 75% Sakha 102, 75%
Giza 177 with 25% Sakha 102; 50% Giza 177 with 50% Sakha 102, 100% Giza 177
and 100% Sakha 102 were used. The experiments were laid out in a split-split plot
design with three replications. A trial was conducted at Experimental Farm, Fac. of
Agric., Tanta Univ. at Kafr EI-Sheikh and Seed Tech. Lab., RRTC. Sakha, Kafr EI-
Sheikh, Egypt during the two growing seasons 199B and 1999. The results revealed
that. the mixed rice variety (25% Giza 177 with 75% Sakha 102) transplanted at 15 x
. 20 cm and fertilized with 60 kg N/fed. gave the highest values of number of tillers/m2,
number panicles/m'', panicle weight (g), panicle length (ern). number of filled
grains/panicle, 1000-grain weight (g), grain yield (t/ha.), biomass yield (tIha.), harvest
index %, hulling %, milling % and head rice % in both season.
