    GROWTH AND YIELD OF TRANSPLANT AUS RICE AS INFLUENCED BY VARIETY AND NUMBER OF SEEDLINGS PER HILL
    (DEPARTMENT OF AGRONOMY, 2010-06) MORSHED, NIAZ
    An experiment was conducted at the Agronomy Farm of Sher-e-Bangla Agricultural University, Dhaka to evaluate ‘the growth and yield of transplanted aus rice as influenced by variety and number of seedling per hill’. The experiment comprised two factors; (1) four varieties viz. V 1 (BRRI dhan 48), V 2 (BRRI dhan 43), V 3 (BRRI dhan 42) and V (ACI hybrid-2) and (2) four seedling treatments viz, H 1 (1 seedling per hill), H (2 seedlings per hill), H 3 (3 seedlings per hill) and H (4 seedlings per hill). Data were collected on plant height (cm), number of tillers per hill, number of leaves per hill, number of panicles per hill, number of grains per panicle, 1000-seed weight, grain yield, stover yield and harvest index (%). Three effects have been considered to evaluate the experiment such as (i) Effect of variety, (ii) Effect of seedling per hill and (iii) Interaction effect of variety and seedling per hill. Results showed that The variety, V 4 (BRRI dhan 42), showed the highest plant height (94.95 cm) but the highest number of tillers per hill (23.62), number of leaves per hill (161.50), number of panicles per hill (16.67), number of grains per panicle (104.40), 1000- seed weight (20.82 g), grain yield (3.743 t/ha), stover yield (5.55 t/ha) and harvest index (40.13%) was obtained from V (ACI hybrid-2). In terms of seedling per hill, H (4 seedlings per hill) showed the highest plant height (94.53 cm) but the highest number of tillers per hill (24.65), number of leaves per hill (161.70), number of panicles per hill (17.22), number of grains per panicle (105.6), 1000seed weight (22.00 g), grain yield (3.92 t/ha), stover yield (5.77 t/ha) and harvest index (40.37%) was obtained from H 4 (1 seedling per hill). With the interaction effect of different variety and seedling per hill the highest plant height (99.40 cm) was recorded in V 3 H 4 1 but the highest number of tillers per hill (25.07), number of leaves per hill (356.60), number of panicles per hill (19.13), number of grains per panicle (121.70), 1000-seed weight (24.67 g), grain yield (4.42 t/ha), stover yield (6.02 t/ha) and harvest index (42.33%) was obtained from V 4 H 1 4 . It may be stated that the best variety was V (ACI hybrid-2) and 1 seedling per hill under the present study. The combination of V (ACI hybrid-2 with 1 seedling per hill) performed the best in producing higher yield than other treatments comprised with other variety and number of seedling per hill under the present study. 3 4 4 H 1 2 4
