| Abstract | ||||
| THIS research aimed to study the effect of some bio-stimulants on …..growth and nutritional status of guava transplants in order to reduce the mineral fertilization during seasons of 2011 and 2012. Results revealed that all treatments significantly increased vegetative growth i.e., (stem height and diameter, number of shoots, number of leaves and leaf area) in both seasons. Results, also, indicated that leaf photosynthetic pigments content (chlorophyll a, b and carotenoids) were increased as well as leaf mineral contents (N, P, K, Ca, Mg, Fe, Mn and Zn) were improved by the different treatments. Therefore, it could be concluded that, all investigated bio – stimulants improve growth and nutritional status especially foliar application of 20 g Kotengin + 40 g phosphorine + 40 g Rhizobacterin/ plant +20 g K2SO4/ plant followed by foliar application of 20 g Kotengin + 40 g Rhizobacterin per plant + PK applied of control. | ||||
