EFFECT OF PLANT GROWTH REGULATOR-FLORA ON THE GROWTH AND YIELD OF TRANSPLANTED AMAN RICE

Abstract

The experiment was conducted in the farm area of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka during the period of July to November, 2015 to find out the effect of plant growth regulator-flora on the growth and yield of transplanted aman rice. BR 11 : Control condition

1 0 : Recommended Fertilizer Doses-RFD ( -1 of N, P, K, S and Zn, respectively : RFD + 1 time spray of Flora, T 3 : RFD + 2 times spray of Flora, T 4 2 : ½ RFD + 1 time spray of Flora, T 5 : ½ RFD + 2 times spray of Flora, T : No chemical fertilizer + 1 time spray of Flora and T 7 6 : No chemical fertilizer + 2 times spray of Flora. Data on different yield contributing characters, yield, nutrient content in grain and straw, nutrient uptake by grain and straw and characteristics of post harvest soil was recorded and significant variation was observed for different treatments. At harvest, the tallest plant 1

-1

treatment, whereas the shortest plant 3 -1

-1

treatment.

- Applications of RFD + 2 times spray of Flora was the superior among the other treatments in consideration of yield contributing characters and yield of BR 11 in transplanted aman season.
