Abstract:

The experiment “Effect of new pre-mix herbicides molecules on yield attributing character and yield of soybean [Glycine max (L.) Merrill] in vertisols” was carried out during kharif season of 2017 at Instructional Cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh, with the objective to find out best pre-mix herbicide for growing soybean under the agro-climatic condition of Chhattisgarh. The soil in the experimental field was clayey (Vertisols) in texture, with low Nitrogen, medium phosphorus, and high potassium content.

The experiment was laid out in randomized block design (RBD) having the combination of eight treatments replicated thrice. The weed management practices selected for study were T1 - Pendimethalin 30% EC+ Imazethapyr 2% SL premix @ 960 g a.i. ha-1 as PE, T2 - Sulfentrazone 48% F+ Clomazone 48 EC @ 725 g a.i. ha-1 as PE, T3- Diclosulam+ Pendimethalin 85% WG @ 102 g a.i. ha-1 as PPI, T4 - Diclosulam+ Pendimethalin 85% WG @ 127.5 g a.i. ha-1 as PPI, T5 - Imazethapyr 35% + Imazamox 35% WG @ 70 g a.i. ha-1 as PoE, T6 - Propaquizafop 2.5% + Imazethapyr 3.75% SL @ 50+75 g ai ha-1 as PoE, T7 – Pendimethalin @ 1000 g a.i. ha-1 as PE and T8 – control (weedy check).

The results of experiment on response of different pre-mix herbicides revealed that yield attributing characters viz., number of pods plant-1, number of seeds pod-1, seed yield, stover yield and harvest index were significantly higher under treatments Propaquizafop 2.5% + Imazethapyr 3.75% SL @ 50+75 g ai ha-1 as PoE (T6). Similarly, all these characters were also superior in treatment of Sulfentrazone 48% F+ Clomazone 48 EC @ 725 g ai ha-1 as PE (T2). Remarkable lowest values were obtained in weedy check.
