Effect of nutrient management and growth retardants on wheat (Triticum aestivum) growth attributes and productivity

Abstract

The field experiment was conducted during the rabi season of 2016-17 at research farm of Wheat and Barley Section, Chaudhary Charan Singh, Haryana Agricultural University, Hisar. The experiment consisted of four nutrient levels (control, RDF, 125% RDN and RDF+ 15 t ha-1 FYM) in main plot and four sprays (water, Cycocel @0.2%, Folicur @ 0.1%, and Cycocel @ 0.2%+ Folicur @ 0.1%) in sub plot in split plot design with three replications. Results revealed that application of RDF+ 15 t ha-1 FYM significantly improved growth parameter (plant height and dry matter accumulation), yields and harvest index as compared to control and RDF. However, it was at par with 125% RDN in all the parameters. Foliar application of Cycocel + Folicur resulted in significantly higher grain yield and harvest index. Whereas, Folicur was found superior in respect of dry matter accumulation and resulted in higher straw yield and biological yield.
