TILLERING DYNAMICS, GRAIN GROWTH AND YIELD PERFORMANCE OF FOUR RICE VARIETIES (Pages : 1 - 4)

Tiller number is the key determinant of rice plant architecture and panicle number and consequently controls grain yield. In today’s crop production systems with high yield outputs, improvement in grain filling has become more challenging than ever before. A field experiment was carried out with four rive varieties viz. Binadhan-5, Binadhan-8, Binadhan-10 and Binadhan-14 during Boro season 2020-21 at BINA farm, Mymensingh. For grain growth studies, ten spikelets were harvested from middle of the panicles of three plants of each variety at 3-day interval starting from fertilization to maturity. Results showed that tillering pattern of all the varieties was similar up to 22 DAT. Binadhan-14 produced the higher number of tillers than Binadhan-5. At the end Binadhan-8 had lower number of tillers than other varieties due to its lower number of secondary tillers. Grain dry weight accumulation was the highest in Binadhan-8 followed by Binadhanb-10. Binadhan-5 and Binadhan-8 showed lower grain dry weight accumulation. Grain dry weight was significantly increased up to 24 days thereafter it is not increased significantly. Although all the varieties had some differences in morphological parameters, however the varieties did not show significant differences in grain yield. Download
