Bioefficacy and Residue Studies of Fantac (Biostimulant) in Rice Crop Under Sub-Tropical Conditions (Report‪)‬

1. Introduction Biostimulants are referred to as positive plant growth regulators or metabolic enhancers which when applied in small quantities enhance the growth and overall development of plants. One such biostimulant is Fantac, a mixture of 5% N-Acetyl thiazolidine carboxylic acid (N-ATCA) and 0.1% folic acid has been recently introduced by Coromandel Fertilizers, Secunderabad, India for attaining higher values of yield attributes in rice. It is a stabilizer buffer which on application to plants helps them to sustain stresses more effectively and enhance crop yields both in quality and quantity [1-3]. It also produces specific effects on the physiological processes of plants [4].
