Plant growth regulators play a central part in plant life. Plant hormones can help to manage equilibrium of phytohormones. Gibberellic acid being known well as plant growth promoting hormone have shown to be involved in a variety of plant growth and development. The experiment was performed with four promising Canola genotypes in order to determine the impact of the GA3 foliar application on canola growth and outputs during 2017-2018 in rabi season at the Nuclear Institute of Agriculture, Tandojam. The results showed that growth regulator levels have significantly influenced the growth and yield of canola crops. It was observed that earlier days to maturity (108.39) was recorded in genotype R00-100/6 and maximum plant height (162.75), branches per plant (10.33), siliquae per plant (362.24), siliqua length (7.39 cm), seeds per siliqua (21.49), seed index (4.50 g) and seed yield (1443.08 kg ha-1) was observed with the application of GA3 5g ha-1 in SURHRAN-2012 and followed by with the application GA3 6 g ha-1 genotype R00-125/12 and Rainbow (P). The final results suggested from the present findings that the variety SURHRAN-2012 x GA35 g ha-1 (foliar application) is a suitable combination for getting maximum yield. Such kind of application of GA3 has been very advantageous in our current research.
