Influence of New Humex, Olivine, Potassium Silicate and Magnetic Iron on Growth of Washington Navel Orange Transplants Budded on Two Citrus Rootstocks
Journal Title: Asian Journal of Advances in Agricultural Research - Year 2017, Vol 4, Issue 4
Abstract
This investigation was carried out on potted transplants of Washington navel orange budded on two citrus rootstocks grown at nursery of Horticulture Department, Faculty of agriculture, Benha University, at Moshtohor, Touckh region Kalubia Governorate, Egypt during two successive 2014 and 2015 experimental seasons in this investigation the influence of two citrus rootstocks, namely: a._Sour orange ''Citrus aurantium'' b._Volkamer lemon ''Citrus volkameriana''. Also, the influence of nine treatments as follow: (T1) Control: Mineral N, P and K fertilization program as control, (T2) New humex 5 mL/L, (T3) New humex (5 mL/L) + potassium Silicate (10 mL/L), (T4) New humex (5 mL/L) + Magnetic iron 250 g/ transplant, (T5) + potassium silicate (10 m/L) + Magnetic iron (250 g per transplant). (T6) olivine (3 cm/L), (T7) olivine (3 cm/L) + potassium silicate (10 mL/L), (T8) Olivine (3 mL/L) + Magnetic iron, (T9) Olivine (3 mL/L) + potassium silicate (10 mL/L) + Magnetic iron. on growth measurements (1- Transplant height (cm) 2- Stem diameter (cm). 3- the number of leaves per transplant. 4- Leaf area. 5- Total assimilation area/transplant 6- Leaves fresh weight (g). 7- Leaves dry weight (g). 8- Root fresh weight (g). 9- Root dry weight (g). 10- Stem fresh weight (g). 11- Stem dry weight (g). 12- Total transplant fresh weight (g). 13- Total transplant dry weight (g). 14- Top dry weight. 15- Top/root ratio.) of Washington navel orange transplants budded on two citrus rootstocks. Uniform and healthy one-year-old transplants were used in this experiment. The influence was evaluated through the response of growth to the specific and interaction effects of both investigated factors. Concerning the interaction effect of the two investigated factors i.e., rootstock type and different fertilization treatments on growth of Washington navel orange transplants, data showed that the highest growth measurements were obtained with the combination between Washington orange transplants budded on Volkamer lemon rootstock and fertilized by (T9) Olivine + SiO2 + Fe Mag and/or (T5) New humex + SiO2 + Fe Mag during the two seasons of study.
