Efficacy of tank mixed herbicides with insecticides in growth and yield of soybean (Glycine max. (L.) Merrill)

Author(s): Vidya Simaiya, MD Vyas and Deepak Kumar
Abstract: The study entitled “Efficacy of Tank Mixed Herbicides with Insecticides in Growth and Yield of Soybean (Glycine max. (L.) Merrill)” was conducted in rainfed condition under “All India Co-ordinated Research Project on soybean at R.A.K. College of Agriculture, Sehore (M.P.), during Kharif 2014.Experiment was laid out in randomized block design with three replications. The treatments included rynaxypyre 20SC 120g a.i./ha, indoxacarb14.5SC 87g a.i./ha, quinalphos 25EC 150ga.i./ha, imazethapyr10SL 100g a.i./ha, quizalofop-p-ethyl 5EC 50g a.i./ha, rynaxypyre 20SC120g a.i./ha + imazethapyr10SL 100 ga.i/ha, rynaxypyre 20SC120g a.i/ha + quizalofop-p-ethyl5EC50ga.i./ha, indoxacarb14.5SC 87g a.i./ha+imazethapyr10SL 100g a.i./ha, indoxacarb14.5SC 87g a.i./ha +quizalofop-p-ethyl 5EC 50g a.i./ha, quinalphos 25EC150g a.i./ha + imazethapyr10 SL100 g a.i./ha, quinalphos 25EC150g a.i./ha + quizalofop-p-ethyl 5EC 50g a.i./ha and untreated check. Among the monocot weeds Echinochloacrusgalli Link, Degiteriasanguinalis, Dinebraarabica, Cyperusrotundus Linn. And Commelinabenghalensis while the dicot weeds Acalypha indica Linn, Eclipta alba, Caesuliaaxillaris Roxb., Digeraarvensis, Corchorousacutangulus and Phyllanthusniruriwere observed in the field. Application of indoxacarb14.5SC 87g ai/ha + imazathapyr10SL 100g ai/ha gave lowest weed dry weight and higher weed control efficiency(75.03%).Application of imazathapyr10SL 100g ai/ha alone or in combination with insecticides viz. indoxacarb, rynyxypyre and quinolphos recorded less weed dry biomass and increased weed control efficiency, imazathapyr controlled both dicot and monocot weeds. Application of quizalofop-p-ethyl5EC 50g ai/ha alone and in combination with insecticides effectively controlled the monocot weeds especially grasses viz. Echinochloacrusgalli Link. Degiteriasanguinali and Dinebraarabica. In growth attributing characters of plants application of indoxacarb 14.5SC87g ai/ha + imazathapyr10SL 100g ai/ha gave significantly higher plant height, branches per plant, plant dry weight, at all observation stages of crop. The pods per plant, seeds per pod, grain yield per plant and seed index were higher in combined application of indoxacarb14.5SC 87g ai/ha + imazathapyr10SL 100g ai/ha followed by rynyxypyre20SC 120g ai/ha + imazathapyr 10SL 100g ai/ha. The seed yield (1.89t/ha) was significantly higher with application of indoxacarb14.5SC 87g ai/ha +imazathapyr10SL 100g ai/ha than all treatments except application of rynyxypyre20SC 120g ai/ha + imazathapyr10SL 100g ai/ha (1.69t/ha).
