تأثیر پرایمینگ بذر و محلول پاشی نانوذرات و سولفات روی بر خصوصیات زراعی آفتابگردان

In order to response effects of priming and foliar application of nano particle and zinc sulphate 0n agronomic traits in sunflower an experiment was carried based on RCBD with four replications. Treatments composed of without priming(control), seed priming with distillate water, seed priming with 300 ppm zinc sulphate, seed priming with 300 ppm zinc sulphate + foliar application with 2 g.L, seed priming with 600 ppm zinc sulphate, seed priming with 600 ppm zinc sulphate + foliar application with 2 g.L, seed priming with 300 ppm nano particle, seed priming with 300 ppm nano particle + foliar application with 0.13 g.L, seed priming with 600 ppm nano particle, seed priming with 600 ppm nano particle + foliar application with 0.13 g.L, control+ foliar application with 0.13 g.L and control+ foliar application with 2 g.L. The results showed that with increasing of zinc sulphate and zinc nano particle increased height plant, head diameter, the percent of empty seed, grain yield and leaf area index. The maximum of head diameter equal to 16.16cm was record from seed priming with 600 ppm nano particle and the maximum of grain yield equal to 6889 kg ha-1 was record from seed priming with 600 ppm nano particle along with foliar application with 0.13 g.L.
