In this study, the effects of different vermicompost doses and applications on chlorophyll content and flag leaf development in three different rice
cultivars (Oryza sativa L.) were investigated. The study used three different rice
cultivars, two different vermicompost applications (foliar and soil), and four different fertilizer doses (0.7, 1.4, 2.1, and 2.8 liters per 100 liters). In this study, the time
of measurement was considered as the fourth source of variation, and measurements were made at seven different times. Chlorophyll measurements were made
at seven different times, every 10 days, starting from the first leaf formation. The
first measurement was made at the beginning of the experiment, and subsequent
measurements were made on days 16, 26, 36, 46, 57, and 67. After the plant had
completed its development, the flag leaf length (in cm), flag leaf width (in cm), and
flag leaf area (in cm2
) were also measured. The experiment was planned according
to a factorial design on randomized plots with 3 replicates. The analysis results
showed that the average flag leaf length was 11.92 ± 2.46 cm, the average flag leaf
width was 0.95 ± 0.07 cm, and the average flag leaf area was 8.45 ± 1.83 cm2
.
Chlorophyll content also varied considerably between measurements made on
different days. The application method, time, and dose of vermicompost have been
shown to have a significant impact on the amount of chlorophyll and flag leaf area
in rice leaves.
