Abstract

Depending on the time of lodging of rice during vegetation the yield and
the quality of white rice has been putted under analysis of San Andrea variety.
The effect of lodging has been determined through analysis of the results
on representative samples of paddy rice, harvested from a plot on which the
lodging had been registered during heading and flowering phases, and from a
plot on which lodging had been registered during later development phases,
during maturing. Results obtained from representative samples from plots
on which there was no lodging effect were used as control. The experimental
material was produced in Kochani region, on the experimental plots of Goce
Delchev University - Shtip, Faculty of Agriculture, Rice Institute during 2014
and 2015. Obtained results prove that lodging in rice has significant influence
over the milling recovery of the rice, as well as over the percentage of whole,
broken, chalky and unhulled grains. The rice’s two-year average reduce level
of milling recovery is at the level of 3.98% in the case with later lodging up to
12.26% in the case with earlier lodging. The percent of whole grains realted
to the control is reduced buy average of 36.98% with earlier lodging and by
13.26% with later lodging respectively. Earlier lodging has significantly higher
influence on the percent of broken grains, for up to 78.03% higher as compared
with control and by 40.36% as compared with the later lodging. The percent of
chalky grains during lodging in the heading-flowering phase is increased for
more than 2 times as compared with the control, and by double as comparison
when compared the control and the maturing phase. As compared to the control
there is an increase of the percent of uhnulled grains in the rice from the earlier
lodging plot by 3 times. As far as the rice obtained from the plot with later
lodging, the percent of unhulled grains compared to the control is 21.43%.
