Effect of root dipping of seedlings with plant growth regulators and chemicals on yield and yield components of rice (Oryza sativa L.) transplanted by broadcast method

摘要

Presowing treatments to seeds or seedlings with growth regulators and other chemical substances have been found effective for improving plant growth and development (Gupta, 1956). However, the role of these growth regulators and other chemicals in improving agricultural productivity of many crops has largely remained unexplored. Thus the present study has been conducted in the Department of Crop Physiology, Tamil Nadu Agricultural University, Coimbatore during 1997-1999 to assess the effect of different growth regulators and chemicals on the yield and yield components of rice, transplanted by broadcast method.
