Effect of post-emergence herbicides on growth and yield of Rabi onion (Allium cepa L.)

Abstract

A field investigation was conducted at Research farm, Department of Agronomy, College of Agriculture, Parbhani. The experimental field was levelled and well drained. The soil was vertisol, low in nitrogen, medium in phosphorus and alkaline in reaction. The experiment was laid out in Randomized block design with eight treatments and three replications. Transplanting of seedling was done with a spacing of 20 cm x 15 cm. It was observed that the application of Haloxyfop 10.8% EC @ 108 g a.i. ha-1 at 15 days after transplanting (T2) recorded higher values of growth and yield contributing characters and maximum yield with better weed control and it was at par with the application of Haloxyfop 10.8% EC @ 135 g a.i. ha-1 at 15 days after transplanting (T3) and Haloxyfop 10.8% EC @ 270 g a.i. ha-1 at 15 days after transplanting (T4).
