EFFECT OF AGE AND NUMBER OF SEEDLINGS IN PRODUCTIVITY OF RICE, DANG, NEPAL

Abstract

The growth, yield and yield attributing characters of Tilki rice variety was evaluated under different age and number of seedlings hill -1 at Dang, Nepal during rainy season from June to September, 2019. The experiment was laid out into factorial design of two different age of seedlings as viz. 20 days and 30 days as main plot factor and four different number of seedlings hill -1 viz. 1, 2, 3 and 4 as sub-plot factor and replicated thrice. The results revealed that highest plant height (79.69cm) at the time of harvesting , LAI (0.17), panicle length (23.55cm), number of grains per panicle (101.82), effective tiller per hill (9.9), non-effective tiller per hill (1.03), total tiller per hill (10.94), test weight (29.22gm) ,economical yield (2.09ton/ha), biological yield (5.28ton/ha) and harvest index (39.34%) were recorded by 20 days of seedlings. Regarding the number of seedlings effective tiller per hill and harvest index were non-significant. Highest plant height (79.65cm), test weight (28.88gm) and LAI (0.17) were recorded in 1 seedling per hill. Longest panicle length (24.11cm) and more number of grains per panicle (100.48) were also recorded in 1 seedlings per hill. Highest number of non-effective tiller (1.66) and total tillers per hill (11.08) in four seedlings per hill were recorded. Highest economical yield (2.21ton/ha) and biological yield (5.43ton/ha) were recorded in 2 seedlings per hill. The interaction effect of age and number of seedlings per hill showed non-significant relation with all the growth, yield and yield attributing parameters except non-effective tiller per hill and LAI.
