Abstract

A field study was conducted during Rabi season of two consecutive years 2019 and 2020 in Crop ResearchFarm at Sam Higginbottom University of Agriculture Technology and Sciences, Prayagraj, Uttar Pradesh,India to determine the role of biofertilizer and growth regulators on production of Indian mustard (Brassicajuncea L.). For the yield and yield parameter viz., seed yield (1.943 and 2.034 t/ha), stover yield (6.747 and6.964), harvest index (22.31 and 22.56 %) and test weight (3.38 and 3.47 g) significantly higher were recordedduring the years 2019-20 and 2020-21 in treatment combination B4 (PSB + VAM + Azotobacter), respectively.Among the growth regulators results revealed that is significantly higher recorded the seed yield (1.842and 1.978 t/ha) and stover yield (6.768 and 6.954 t/ha) during the years 2019-20 and 2020-21, respectivelyin the treatment G1 [Gibberellic acid 50 ppm (0.05 g/l)].
