Abstract:
A field experiment was conducted during Spring 2014-16 at Research Farm of Tirhut College of Agriculture, Dholi, RPCAU, Pusa, Bihar, India to investigate the effect of manual herbicidal and integrated treatments on weed dynamics, growth, yield and economics of sunflower (KBSH-44). The experiment was conducted in randomized block design with 10 treatments and three replications. Significantly higher yield (22.51q/ha), highest plant height (171.06 cm), greater head diameter (16.64 cm) and lowest weed population were recorded with weed free treatment (twice hand weeding at 20 and 40 DAS) whereas, highest net returns and B: C ratio were found in treatment having combination of pendimethalin @ 1 kg a.i. as pre-emergence with propaquizofop @ 62 a.i./ha at 20 DAS.
