Abstract

A field investigation entitled “Weed management in summer groundnut (Arachis hypogaea L.)” was conducted in Summer season of 2023 at the AICRP on Groundnut, Mahatma Phule Krishi Vidyapeeth, Rahuri to study different weed management methods in summer groundnut. The experiment was laid out in randomized block design (RBD) with three replications. The experiment consists of ten treatments viz., T1 : Diclosulam 84% WDG @ 20 g a.i. ha-1 (PE); T2 : Diclosulam 84% WDG @ 25 g a.i. ha-1 (PE); T3 : Pendamethalin 30% E.C. @ 1.0 kg a.i. ha-1 (PE); T4 : Diclosulam 84% WDG @ 20 g a.i. ha-1 (PE) fb hand weeding at 20 and 40 DAS; T5 : Diclosulam 84% WDG @ 25 g a.i. ha-1 (PE) fb hand weeding at 20 and 40 DAS; T6 : Diclosulam 84% WDG @ 20 g a.i. ha-1 (PE) fb quizalofop-p-ethyl 5% E.C. 50 g a.i. ha-1 (PoE) at 20 and 40 DAS; T7 : Diclosulam 84% WDG @ 25 g a.i. ha-1 (PE) fb quizalofop-p-ethyl 5% E.C. 50 g a.i. ha-1 (PoE) at 20 and 40 DAS; T8 : Pendamethalin 30% E.C. @ 1.0 kg a.i. ha-1 (PE) fb quizalofop-p-ethyl 5% E.C. 50 g a.i. ha-1 (PoE) at 20 and 40 DAS; T9 : Weedy free check (at 20 and 40 DAS) and T10 : Weedy check. As regards yield attributing characters, significantly higher dry pod yield (32.56 q ha-1), haulm yield (40.64 q ha-1), biological yield (73.20 q ha-1) were recorded under treatment weed free i.e., T9 than other treatments except application of diclosulam 84% WDG @ 25 g ha-1 (PE) fb hand weeding at 20 and 40 DAS i.e., T5 which recorded dry pod yield (30.93 q ha-1), haulm yield (38.14 q ha-1), biological yield (69.07 q ha-1) and diclosulam 84% WDG @ 20 g ha-1 (PE) fb hand weeding at 20 and 40 DAS i.e., T4 which recorded dry pod yield (30.30 q ha-1), haulm yield (37.39 q ha-1), biological yield (67.69 q ha-1). Significantly the highest gross monetary returns was obtained in weed free treatment (` 168897 ha-1). However, application of diclosulam 84% WDG @ 25 g ha-1 (PE) fb hand weeding at 20 and 40 DAS recorded a significantly maximum net monetary returns (` 96867 ha-1) and B:C ratio (2.53) than other weed management treatments except treatment or diclosulam 84% WDG @ 25 g ha-1 (PE) fb hand weeding at 20 and 40 DAS (` 93939 ha-1 and 2.49, respectively). While, weedy check obtained minimum gross monetary returns, net monetary returns and B:C ratio among all the treatments

Conclusion

Amongst a application of different herbicidal treatments to summer groundnut crop, the treatment diclosulam 84% WDG @ 25 g ha-1 (PE) fb hand weeding at 20 and 40 DAS recorded significantly higher growth and yield attributing characters. Similarly, it also resulted into higher dry pod, haulm and biological yield (30.93, 38.14 and 69.07 q ha-1, respectively) and harvest index (44.68 %), except weed free treatment. Among weed management treatments, the application of diclosulam 84% WDG @ 25 g ha-1 (PE) fb hand weeding at 20 and 40 DAS obtained maximum net monetary return (` 96867 ha-1) and B:C ratio (2.53) than rest of all treatments
