Assessment of System of Mustard Intensification (SMI) with Plant Geometry and Age of the Seedlings in Enhancing Growth and Yield Attributes of Mustard (Brassica juncea L.)

The field experiment entitled “Assessment of system of mustard intensification (SMI) with plant geometry and age of the seedlings in enhancing growth and yield attributes of mustard (Brassica juncea L.)” was conducted at College Farm, Agricultural College, Polasa, Jagtial in Rabi, 2022. The experiment was laid out in randomized block design with eleven treatment combinations by replicating thrice. The treatment includes T1: Conventional sowing (dibbling) with spacing 45 x 15 cm without gap filling,T2: Conventional sowing (dibbling) with spacing 45 x 15 cm with gap filling, T3: 15 days old seedlings with spacing 30×30 cm, T4: 15 days old seedlings with spacing 45×45 cm, T5: 15 days old seedlings with spacing 60×60 cm, T6: 20 days old seedlings with spacing 30×30 cm, T7: 20 days old seedlings with spacing 45×45 cm, T8: 20 days old seedlings with spacing 60×60 cm, T9 : 25 days old seedlings with spacing 30×30 cm, T10 : 25 days old seedlings with spacing 45×45 cm, T11: 25 days old seedlings with spacing 60×60 cm. Thus from results obtained from present investigation it can be concluded that transplanting 25 days old seedling with 30 x 30 cm spacing under System of Mustard Intensification (SMI) resulted in higher plant height (182.5) and dry matter production (4660 kg ha-1) while Transplanting 25 days old seedling with 60×60 cm resulted in higher no. of primary and secondary branches plant-1(9.0 and 24.6), no. of siliqua plant-1 (656.3) and no. of seeds siliquae-1(14.7).
