Effect of gibberellin, nano-nutrition with titanium, zinc and iron on yield and some physiological and qualitative traits of white beans

Plant nutrition has a vital role in crop production. This study was performed to investigate the effects of different application methods some nutrients (nano Fe, Zn, and Ti), gibberellin on yield, morphophysiological grain protein white beans 2018 as factorial experiment randomized complete block design with four replications. Experimental factors included seed priming (hydropriming, priming, titanium nano dioxide, nano-Zn priming) micronutrient foliar spraying (zinc, iron, zinc + iron). The results illustrated that significantly affected yield components chlorophyll content. height increased treatment iron by 13% compared control. Furthermore, this enhanced number sub-branches per plant 32% Grain such pods 100-grain weight were also nano-Zn, simultaneous 18%, so 2649 kg ha–1 hydropriming reached 3211 iron. Nano-Zn caused highest biological (9011 ha–1), which 19% percentage 21%. along leaf content other treatments. Therefore, increase beans, well can be used.
