Experiment was conducted in randomized block design with 18 treatments along with three replications. The treatment T5 (Weed free) recorded significantly maximum bulb weight (g), bulb diameter(cm), no of scales/bulb, bulb yield/plot(kg) total bulb yield(q/ha), benefit cost ratio and quality parameters i.e., TSS, ascorbic acid, reducing sugar, non-reducing sugar and total sugars were obtained in the treatment T5 (Weed free).Therefore, it is concluded that judicial application of herbicide along with fertilizers will produce higher yield along with quality bulbs at low cost of production of onion.
