Abstract
A field experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University during August to December 2012 to find out the effect of plant extracted pyroligneous acid (vinegar like substance extracted from wood) with trade name PRH on T. aman rice (BRRI dhan34). There were six treatments viz., Control (no fertilizer and no PRH); 100% recommended dose of fertilizer; 100% recommended dose of fertilizer plus 100% PRH; 50% recommended dose of fertilizer plus 50% PRH; 50% recommended dose of fertilizer plus 100%PRH; and no fertilizer but 100% PRH. Results showed that at harvest the highest plant height was obtained from 100% recommended dose of fertilizer application, whereas the lowest from control (no fertilizer + no PRH). The highest tillers hill-1 was obtained from 50% recommended dose of fertilizer + 50% PRH application and the lowest from control (no fertilizer + no PRH) but the highest effective tillers hill-1 was obtained from 100% recommended dose of fertilizer application and the lowest from control (no fertilizer + no PRH). Grain yield was significantly the highest (5.05 t ha-1) with 50% recommended dose of fertilizer + 50% PRH, whereas the lowest (2.55 t ha-1) yield was obtained from control (no fertilizer + no PRH). The higher grain yield was attributed mainly due to highest number of effective tillers hill-1, filled grains panicle-1 and 1000-grain weight obtained from 50% recommended dose of fertilizer + 50% PRH.
