The study  was conducted during rabi 2017-18 and 2018-19 at Crop Research Farm , Eastern Section of  Birsa Agricultural University, Ranchi-834006 (Jharkhand) to evaluate the Fertility levels and application of growth regulators on growth  of wheat (Triticum aestivum L.) with objective to achieve yield maximization. The experiment was laid out in split plot design with three replications. The treatments consisted of four fertility levels absolute Control;100% (Recommended Dose of Fertilizer);RDF150:60:40;150%RDF and 150%RDF+15tFYM/ha) in main plot and four growth regulators (Two sprays each of water , CCC (0.2%) ,Tebuconazole (0.1%) ;CCC (0.2%)+ Tebuconazole (0.1% ).The soil of the experimental field was clay loam in texture , acidic in reaction, low in available nitrogen, phosphorus and medium available potassium. Results revealed that application of 150% RDF+15tFYM led to higher plant height, dry matter accumulation and lodging score of wheat at harvest in both the years. The combined application of (CCC)+Tebuconazole reduced the plant height of wheat by 22.0%  and 20.3% over  water spray during 2016-17 and 2017-18 respectively .The minimum mean lodging score  mean 1.0 and 1.5 were recorded with application of CCC and Tebuconazole during 2016-17 and 2017-18 respectively. The significantly higher number of  spike (368 &388 m-2), spike length (11.6 &12.40 cm) , number of spikelets/spike(21.40&22.50) and test weight (39.13&40g) were registered with application of 150% RDF+15tFYM during 2016-17 and 2017-18 respectively as compared to 100%RDF. The combined spray of CCC+Tebuconazole enhanced the test weight by 5.6% & 3.7% over water spray during both the years 2016-17 and 2017-18, respectively. The significantly maximum grain, straw and biomass yield of wheat were recorded with 150% RDF+15tFYM which were 5.8 & 17.03 %, 16.3& 32.2%, and 10.82 & 24.7% higher over 100% RDF during both the years 2016-17 and 2017-18, respectively. The grain yield of wheat due to combine application CCC and Tebuconazole was found significantly higher (10.84and11.15%) during both the years. There were no differences in straw and biomass yields of wheat due to different growth regulators.
