Journal Title: Haya: The Saudi Journal of Life Sciences - Year 2017, Vol 2, Issue 1
Abstract
Abstract: An observation trial was conducted at the research field of Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during November 2012 to March 2013. This experiment was under taken to find out the efficiency of weed control in wheat field by the application of sorghum plant parts water extract. The treatments were: i) T1= 2 kg dry sorghum plant parts/10 lit water extract/ha ii) T2= 1 kg dry sorghum plant parts/10 lit water extract/ha and iii) T3= only water spray. Treatment, T1 showed the minimum number of weeds (28) compared to treatment T2 (43). But minimum dry wt of weeds were found in treatment T2.Weed control efficiency, (WCE) was also highest in treatment, T2 (17.08) compared to treatment T1 (13.76). The grain yield was highest in treatment, T2; though the length of spike and no. of grains/spike was highest in treatment, T3 (Only water spray). Keywords: Allelopathic, sorghum, water extract, weed, wheat.
