Abstract:

A study was conducted at Agronomic Research Farm, Department of Agronomy, University of Agriculture, Faisalabad, Pakistan during 2012-13 to explore the influence of seed priming treatments especially thiourea on the emergence, growth and yield of late sown wheat. Six seed priming treatments (T1: control, T2: hydropriming, T3: 200 ppm, Thiorea T4: 400 ppm thiourea, T5: 600 ppm thiourea, and T6: 800 ppm thiourea were trial on two wheat (Triticum aestivum L.) cultivars viz; Millat-2011 and Punjab-2011. Leaf area index and crop growth rate were recorded at 15 interval from 45 to 105 days after sowing while data on yield and yield related traits were recorded at crop maturing. The results showed that seed primed with thiourea at 800 ppm took minimum time to reach at 50 percent emergence. In both cultivars, maximum leaf area index and crop growth rate were observed in thiourea primed seed at 400 ppm concentration at each interval while minimum dry weight was observed in control at each interval. It further improved yield and yield related attributes (productive tillers, 1000 grain weight, number of grain per spikes, grain and biological yield as well as harvest index). Improved yield in thiourea primed seeds mainly is attributed to uniform germination, good stand establishment and increase in productive tillers. Hence, thiourea seed priming can be used to improve the performance of late sown wheat.
