Effect of root enhancer and cytoplus on chemical characteristics of olive sapling cultivar sourany

الملخص EN

A Factorial experiment within The randomized complete block design (RCBD ) during the two season of growth 2016 -2017 In lath house was carried out to investigate the influence of adding organic fertilizers "Root Enhancer" and "Cytoplus" soil applied on chemical characteristics on one year old "Sourany" olive sapling .

The soil-applied amounts of "Root Enhancer" (E) at four levels (0, 2, 3, 4 g.

sapling -1) and "Cytoplus" (C) at four level (0, 3, 5, 7 ml.

sapling -1).The adding of organic fertilizer E (4g.

sapling -1) gave significantly highest values of chlorophyll contents was 182.2 ,231.9 mg.100 g-1 F.W , vegetative dry matter was 48.63, 49.12 % , Leaf nitrogen concentration was 2.246 ,2.438 % , Leaf phosphor concentration was 0.372 ,0.376 % , Leaf potassium concentration was 2.658 ,2.669 % , Leaf calcium concentration was 2.582,2.425 %, Carbohydrate in shoot was 9.340,8.234 %, Nitrogen in shoot was 0.813, 0.804 % , Root uptake efficiency 34.24, 36.33% .

The adding of organic fertilizer C (7ml.

sapling -1) gave significantly highest values of chlorophyll content at 171.6 , 163.6 mg.100 g-1 F.W , vegetative dry matter of 51.57 ,52.63 g , Leaf nitrogen concentration of 2.426 , 2.615% , Leaf potassium concentration of 2.482 ,2.420 % , Leaf calcium concentration of 2.112 ,2.082 % Carbohydrate in shoot 8.637,8.544% , Nitrogen in shoot 0.772 ,0.763 % , Root dry matter 34.73,40.24 g % , Root uptake efficiency 37.96 , 38.77 % .

The interaction between experimental factors significantly increased most Characters.
