Evaluation of non-chemical weed control methods in wheat (Triticum aestivum L.)

Abstract

A field experiment was conducted to evaluate the non-chemical weed control methods in wheat (Triticum aestivum L.). Field experiment was designed in randomized block design with three replications. The observations were recorded count and dry matter accumulation of grassy weeds and broad leaf weeds in wheat, weed control efficiency, weed index and grain yield of wheat. Highest weed control efficiency was recorded in weed free (100%), stale seedbed technique and wheat straw mulch (76.23%) and stale seedbed technique and two hoeings (77.73%) and two hand hoeing (74.50%). Weed index recorded in weedy check (54.27%) and weed free (0%). Lowest narrow and broad leaf weed dry matter was recorded in weed free. Maximum grain yield was recorded under weed free (47.9 q ha-1) which remain at par with stale seedbed technique and straw mulching (46.8 q ha-1), stale seedbed technique and two hoeings (47.2 q ha--1), and two hand hoeing (46.5 q ha-1).
