%0 Journal Article %T Role of salicylic acid as foliar spray on hydride rice (BRRI Hybrid dhan3) cultivation in Bangladesh %A Amena Sultana %A Mohammad Issak %A Most Moslama Khatun %J Research in Agriculture Livestock and Fisheries %D 2017 %R https://doi.org/10.3329/ralf.v4i3.35092 %X The experiment was conducted to study the effect of salicylic acid (SA) as foliar spray on yield and yield contributing characters of BRRI Hybrid dhan3.The experiment was laid out in a randomized complete block design (RCBD) with three replications and six treatment combinations as, T1: 0 ¦ÌM SA, T2: 200 ¦ÌM SA, T3: 400 ¦ÌM SA, T4: 600 ¦ÌM SA, T5: 800 ¦ÌM SA and T6: 1000 ¦ÌM SA. The results revealed that biomass production, dry matter production and yield and yield contributing characters were significantly increased due to the foliar application of SA. At the maximum tillering (MT) stage, the highest biomass production (15.0 t/ha) and dry matter production was observed in T3 treatment. Treatments T4, T5 and T6 showed significant variation on the effective tillers/hill. The maximum effective tillers/hill were found in the treatment T6. The percentages of spikelet sterility were decreased with increasing the level of SA and the percentage of filled grains/panicle were increased with increasing level of SA. The insect infestation was reduced with increasing level of SA to up to 1000 ¦ÌM. The maximum grain yield (9.21 t/ha) and straw yield (9.22 t/ha) was found in the treatment T6 which was identical to T5. On the other hand, in all cases the lowest results were found in the control treatment. The result showed that grain yield of rice increased with increasing level of SA to up to 1000 ¦ÌM (T6 treatment). Our results suggest that foliar spray of SA might be applied to increase the yield of hybrid rice in Bangladesh. Res. Agric., Livest.
