Abstract: The experiment was conducted during 2016 and 2017 to study the effect of film coating polymers on growth, yield and seed quality of Rice (Oryza sativa L.) variety MTU 1010. Experiment was laid out in Randomised Block Design with four replications. Four treatments viz.T1 (treatment with water + Thiram), T2 (Polymer DISCO AG SP RED L-200 + Thiram + Carboxine), T3 (Polymer DISCO AG SP RED L-200 +Thiram+ Genious coat) and T4 (Polymer DISCO AG SP RED L-200 + Thiram + Quick roots or Mycorriza) were compared with control T0 (no treatment). It was revealed that highest seed yield in terms of kg ha-1 was recorded in T4 (Polymer DISCO AG SP RED L-200 +Thiram+ Quick roots or Mycorriza) (5100.0 kg ha-1) followed by T3 (Polymer DISCO AG SP RED L-200 +Thiram+ Genious coat) (5054.2 kg ha-1). Among the seed quality parameters under storage, germination percentage was highest in T4 (93.5) but with increase of storage period germination percentage decreased significantly. Seeds treated with T4also recorded maximum viable seeds (98.4%), maximum seedling length (26.4 cm) and vigour index value (2467.6). Considering seed yield and seed quality parameters, T4 (Polymer DISCO AG SP RED L-200 +Thiram+ Quick roots or Mycorriza) appears to be ideal among thetreatments for quality seed production in rice.
