Abstract
Currently, the impact of climate is the topmost challenge for agriculture.
Unpredictable phenomena greatly affect rice cultivation, leading to a decline in
productivity. The introduction of new rice varieties with more enhanced traits and
heightened resilience to environmental stresses emerges as a solution to mitigate
environmental problems. Hence, a field evaluation of hybrid rice entries in Bacnotan, La
Union, during the dry season was conducted to determine their growth and yield
performance. Characterization of the soil physical-chemical properties of the study site
was also conducted.
Soil analysis shows that the experimental area has a pH of moderate acidity (pH
5.61-5.91), moderate to good soil organic matter level (2.42-3.00%), and low electrical
conductivity (0.0011-0.002 dS/m). The growth performance of different hybrid rice entries
varied significantly. NCT-HYBRID 3 and M103 (Check variety) had the most tillers at the
booting and maximum tillering stage; NCT-HYBRID 4 recorded the maximum plant height
at the maximum tillering stage and NCT-HYBRID 7 at the maturity stage; entries NCT
HYBRID 9 and M103 (Check variety) are the earliest varieties to flower and mature; NCT
HYBRID 7 has the longest culm length; NCT-HYBRID 10 recorded the longest panicle
length (26.14 cm); M103 (Check variety) has the most productive tiller; NCT-HYBRID 2
has the least non-productive tillers; NCT-HYBRID 6 and M103 (Check variety) had the
least empty grains/panicle; and NCT-HYBRID 8 has the heaviest 1000 grain weight. In
terms of grain yield, all NCT rice entries produced a comparable grain yield with the two
check varieties, which range from 4.57 to 6.72 tons/ha.
