Abstract:
The field experiment was conducted at Farm B of College of Agriculture- Ganjbasoda, Vidisha during 2019-20 and 2020-21. The purpose of the experiment was to study the effect of pre emergence herbicide against complex weed flora in chickpea. The experiment was laid out in a randomized block design with six treatments, viz., T₁- Flurochloridone 20% CS @ 500 g a.i/ha, T₂- Flurochloridone 20% CS @ 625 g a.i/ha, T₃- Flurochloridone 20% CS @ 750 g a.i/ha, T₄- Pendimethalin 30% EC @ 1000 g a.i/ha, T₅- Weed free check and T₆- Weedy check with four replication. Dominant broad leaf weeds that invade the field were Anagallis arvensis, Chenopodium album and Argemone maxicana. Besides, Parthenium hysterophorous, Sinapsis arvensis and Amranthus retroflexus were also observed. Among the herbicidal treatments, Flurochloridone 20% CS @ 750 g a.i/ha registered higher weed control efficiency and showed minimum weed index during both the years followed by T₂ (11.08 and 10.73%).Weed free plot produced maximum yield of chickpea closely followed by Flurochloridone 20% CS @ 750 g a.i/ha which was at par to Flurochloridone 20% CS @ 625 g a.i/ha. Phytotoxicity on succeeding crop soybean was not observed during the course of investigation and this crop registered almost similar plant population and yield under all herbicidal treatments.
