Impact of weed and fertilizer management on yield and quality parameters of onion (Allium cepa L.) Var. Pusa Red under Lucknow conditions

Abstract

The present investigation was conducted during rabi session 2015-16 at Horticulture Research Farm, Department of Applied Plant Science (Horticulture), Babasaheb Bhimrao Ambedkar University, Lucknow to find out the impact of weed and fertilizers management on yield and quality parameters of onion (Allium cepa L.). 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.
