Pre-Sowing Seed Treatment of Selected Botanical Extracts and Biofertilizers on Growth, Yield and Yield Attributing Traits of Mustard (Brassica juncea.L)

Abstract

The present investigation was carried out for “Pre-sowing seed treatments of selected botanicals extract and biofertilizers on growth, yield and yield attributing traits of Mustard (Brassica juncea L.)”. For this pur- pose, 13 priming treatments including control on Mustard seeds variety were used to study under filed condi- tions during rabi, 2021-22. Field experiment was laid out in Randomized Block Design (RBD) with three replications respectively during Rabi 2021-22. Analysis for the data in field experiment revealed significance mean sum of squares due to seed priming treatments for all the characters under study. In order to standardize method of seed priming specific to mustard crop and they were evaluated by screeming a range of duration and concentration Viz T0- Control, T1 Neem Leaf Extract 5% (6Hrs), T2 Neem Leaf Extract 10%(6Hrs), T3 Moringa Leaf Extract 5% (6Hrs), T4 Moringa Leaf Extract(10%Hrs), T5 Trichoderma viridae 0.1%(6Hrs), T6 Trichoderma viridae 0.3%(6Hrs), T7 Azosprillum 0.1%(6Hrs), T8 Azosprillum 0.3%(6Hrs), T9 Neem Leaf Extract + Moringa Leaf Extract(5% +3%) 6hrs, T10 Trichoderma viridae + Azosprillum (0.1%+0.1%), T10 Trichoderma viridae + Azosprillum (0.1%+0.1%), T11 Neem Leaf Extract + Trichoderma viridae (3% +0.1%), T12 Moringa Leaf Extract + Azosprillum(3% +0.1%)To find out Influence of different seed treatment on growth, yield and seed quality parameters of mustard showed that significant treatment Field emergence (%), Plant height (30,60,90 DAS), Days to 50% flowering, Number of branches per plant, Number of silique per plant, Number of seeds per silique, Seed yield per plant (g),Seed yield per plot (g),Biological yield (g),Harvest index. The study helps to improve the quality to improve of seed with help of seed different Leaf extracts and Biofertilizers priming treatment which are cost effective and economic, non- toxic, ecofriendly sources. Pre- sowing treatment with It is concluded from the present study that the seeds of Mustard (Variety - sonalika) were treated with T9 Neem Leaf Extract + Moringa Leaf Extract(5% +3%) 6hrs enhanced the Field emergence percentage, Plant height (cm), Number of branches per plant, Number of silique per plant, Number of seeds per silique, Seed yield per plant, Seed yield per plot, Biological yield, Harvest index followed by T12 Moringa Leaf Extract + Azosprillum(3% +0.1%) and T4 Moringa Leaf Extract(10%Hrs) as compared to control ( untreated ) seeds.
