Title
The effects of humic acid on some growth indices and yield of roselle (Hibiscus sabdariffa) under water stresses
Authors
Abstract
To study the effect of humic acid on some growth indices and yield roselle (Hibiscus sabdariffa) under water stresses, an experiment was conducted in the research of Jiroft in 2013. Field experimental was carried out as split plot design with three replications. Water deficit stress set as main factor with three levels ( A1 =Irrigation after 50,A2 = 100 and A3 =150 mm evaporation from pan class A) and humic acid was in four manners (B1= non humic acid, B2= Irrigation water soluble, B3== Irrigation water soluble and One spraying, B4= Irrigation water soluble and two Spraying). applicated humic acid to form Irrigation and to form spary to arranjment with compactness(10kg/he), (250ml/100l). The results showed that water deficit stress had significantly decreased high, number of branches, number of fruit, stem diameter, economic yield. While application humic acid Plant resistance to redus this characters increased. As a result Caused damping the harmful effects of drought stress.
