Abstract:
An experiment was laid out to study the effect of integrated weed management practices for weed management in wheat during Rabi seasons of the year 2021-2022 in Randomized Block Design at Post Graduate Research Farm, Agronomy Section, College of Agriculture, Dhule. Experiment consisted of nine treatments with three replications. The results revealed that weed intensity and weed dry weight were found significantly lower in weed free (T₂) treatment which was statistically at par with treatment T₅ i.e. pendimethalin 30% EC 1.0 kg A.I. ha^-1 (PE) fb two HW at 20 and 40 DAS and treatment T₉ i.e. pendimethalin 30% EC 1.0 kg A.I. ha^-1 (PE) fb metsulphuron methyl (PoE) + one HW at 40 DAS. Weed free also showed significantly higher weed control efficiency throughout the crop growth period. The highest benefit: cost ratio was recorded under treatment T₉ i.e. pendimethalin 30% EC 1.0kg A.I. ha^-1 (PE) fb metsulphuron methyl (PoE) + one HW at 40 DAS followed by weed free and treatment T₅ (2.51, 2.40 and 2.37. respectively). Hence, it can be concluded that treatment T₉ i.e. pendimethalin 30% EC 1.0 kg A.I. ha^-1 (PE) fb metsulphuron methyl (PoE) + one HW at 40 DAS were comparable with weed free and suitable for weed control in wheat crop.
