Abstract:
The present investigation entitled “Role of GA<sub>3</sub>, SA and ABA on growth and yield of Indian mustard [<em>Brassica juncea </em>(L.) Czern. &amp; Coss.] under rainfed condition” was conducted during <em>Rabi</em> season, 2013-14 at the Student Instructional Farm (SIF) of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.), India. The treatments were comprised of foliar spray of three plant growth regulators (PGRs) of different concentrations <em>viz</em>., GA<sub>3</sub> (50 ppm, 100 ppm), Salicylic acid (0.5 mM, 0.7 mM) and ABA (10<sup>-5</sup> M) along with untreated control (distilled water spray) &amp; spraying was done at 30 DAS. Experiment was setup in randomized block design with twelve treatments and three replications on Narendra rai (NDR-8501) under normal and rainfed conditions. PGRs were applied on the foliage of plant at 30 DAS. Drought was imposed for 30 days by curtailing irrigation at 30 DAS and normal condition plots were irrigated at 30 DAS. Normal and rainfed conditions plots were irrigated at 60 DAS. On the basis of results obtained foliar application of plant growth regulators improved all the growth (dry matter partitioning and relative water content) and yield and yield attributing characters under normal and rainfed conditions. But the effect of SA @ 0.7 mM was more pronounced and mitigate the adverse effect of rainfed condition on mustard.
