Effect of seed priming treatments on growth, yield, and seed quality of wheat (Triticum aestivum L.) variety K-607 (Mamta)

Abstract

The present study was conducted during the Rabi seasons of 2017-18 and 2018-19 at the New Dairy Farm, Kalyanpur, Kanpur, to evaluate the effect of different seed priming treatments on growth, yield, and seed quality of wheat variety K-607 (Mamta). Treatments included hydropriming (4 and 8 hours), chemical priming with Thiram and Trichoderma viride, nutrient priming using potassium nitrate (0.5% and 1%), and hormonal priming with GA₃, NAA, and IAA at 50 and 100 ppm concentrations. Significant improvements were observed in all growth and yield parameters, including plant height, tiller count, spike length, number of grains per spike, and seed yield. The treatment GA₃ at 50 ppm (T9) recorded the highest seed yield (6006.67 kg/ha), followed by 8 hrs hydration + Thiram 3 g/kg seed (T4) and hydration for 8 hrs (T2). These treatments also significantly improved seed quality. Thus, seed priming, particularly with GA₃ 50 ppm, offers a simple and effective method for enhancing wheat productivity and seed performance.
