Effect of different seed priming treatments on yield attributes of wheat (Triticum aestivum)

The effect of different priming treatments were evaluated during 2015–16 and 2016–17 with two wheat (Triticum aestivum L.) varieties V1: GW 496 and V2: Lok 1. The seeds of both the varieties were primed with different priming treatments, viz. P1, GA3 (50 ppm); P2, IAA (100 ppm); P3, KNO3 (3%); P4, KCl (2%); P5, Tricoderma harzianum @10 g/kg and P6, Tricoderma viride @10 g/kg along with unprimed seeds as a control (P7). The variety Lok 1 (V2) showed positive response to different priming treatments and seeds of Lok 1 primed with KNO3 (3%) recorded significantly higher pooled average field emergence (96.42%), number of effective tillers (7.75), spike length (12.99 cm), seed yield per plant (13.55 g), seed yield per plot (2.45 kg) during both the years followed by GA3 (50 ppm) primed seeds which recorded at par values for almost all the seed yield attributes. The unprimed seeds of wheat variety GW 496 recoded significantly lower values for all the observed characters for both the experimental years.
