Abstract
Plant hormones play a vital role in combination of many growths and behavior process of plants life. Plant growth regulators can help to manage balance of phytohormones. Auxin and gibberllic acid being known well plant growth promoting hormones have shown to be involved in a variety of plant growth and development. The field experiment was conducted to evaluate the effect of foliar application of nitrogen, phosphorus; gibberellic acid and indole-3-acetic acid with two canola mutants R00-125/14, W97-75/16 with their respective parents Rainbow and Westar were used in this experiment. The application of N, P fertilizers increased 67% seed yield in brassica. The early days to maturity was recorded under treatment of and maximum number of branches plant-1, siliqua plant-1, 1000 seed weight and seed yield kg ha-1 was recorded under the treatment of 90N-45P-1 0GA3-10 IAA while minimum number of branches plant-1, sliqua plant-1 and 1000 seed weight were recorded under the treatment of 90N-45P-15GA3-15 IAA. It is recommended that brassica should be sown under the treatment of 90N-45P-10GA3-10 IAA to achieve best performance to produce more seed yield and quality trait in brassica.
