Use of growth regulators for lodging tolerance and increasing productivity of barley (Hordeum vulgare): An empirical study

A field study was carried out during winter (rabi) seasons of 2015–16 to 2017–18 at Karnal, Hisar, Ludhiana, Durgapura and Agra evaluate the efficacy plant growth regulators (CCC, ethephon their combination) reduce lodging enhance productivity barley (Hordeum vulgare L.) under high nitrogen level. Results revealed that application 75 kg N/ha increased grain yield by 3.17% over recommended 60 kg/ha. The pooled mean score with regulators, viz. CCC, combination both 5.21, 4.28 3.03 respectively, while without 9.57. With regulator, in range 2.5–4.1 q/ha (5.7–9.4%). effect CCC relatively lesser as compared ethephon, however gave additive on increment (8.78%). Application 1000-grain weight 6.21% control. Therefore, use i.e. (75 N/ha) can be advocated a sustainable strategy through decreasing problem.
