Response of citrus aurantium and volkameriana rootstocks to spraying with coconut liquid and dry baker's yeast extract

The experiment was conducted in the vegetable canopy of the Horticulture and Landscape Department ، College of Agriculture / University of Kerbala for the period from mid-February to the end of June of 2023.
The experiment was carried out using Randomized Completely Block Design (R.C.B.D) as a factor experiment with three factors: citrus rootstock (sour orange and Volca Mariana) and coconut liquid extract in three concentrations (0،100،200) m.L-1 and dry baking yeast extract in three concentrations (0، 4، 8) g.L-1 and three repeaters. At the end of June 2023 ، measurements were taken and the results were analyzed statistically using the Anova Table according to the Genstat program (2010) ، and the averages were compared using the lowest significant difference (L.S.D) below the probability level of 5% and the most important results reached:
1. Rootstock Volca mriana excelled in the chemical traits of leafs the studied leaves (nitrogen ، phosphorus ، potassium ، protein ، carbohydrates ، iron ، zinc ، total chlorophyll ، and ascorbic acid C) ، vegetative traits (average stem length ، average stem diameter ، number of leaf ، leaf area ، dry weight of vegetative total) and root traits (root length ، root diameter، root size ، dry weight of the root group) by achieving the highest averages of (1.6606% ، 0.5089% ، 1.6644% ، 10.367% ، 13.009% ، 98.865 m.kg-1، 45.460 m kg-1، 3.262 m g-¹، 33.758 m g-¹) and (30.815 cm، 2.4964 mm ، 60.852 seedling leaf-1، 1382.93 cm2، 28.399 g) and (45.839 cm ، 2.6317cm، 25.539 cm3، 17.5989 g) respectively . While the origin of citrus orange exceeded the average relative moisture content of the leaves amounted to. (%61.258)While the coconut liquid treatment achieved 200 m L-1 achieved significant superiority in traits the studied (nitrogen ، phosphorus ، potassium ، protein ، carbohydrates ، iron ، zinc ، total chlorophyll ، and ascorbic acid C) Vegetative traits (average stem length، average stem diameter، number of leaf ، leaf area، dry weight of vegetative total ، relative moisture content of leafs) and root traits (root length ، root diameter ، root size ، dry weight of the root group) giving them the highest averages of (1.9792%، 0.6022% ، 1.8492% ، 12.337% ، 17.266% ، 111.884 m kg-1، 50.257 m kg-1، 3.649 m g-1 38.771 m g-¹) and (31.861cm ، 3.1605 mm ، 73.522 seedling leaf-1 ، 2023.48 cm2 ، 34.155g ، 64.576 %) and (52.568 cm، 2.6992 mm ، 30.590 cm3 ، 18.9636 g) respectively .The treatment sprayed with dry baking yeast extract at a concentration of 8 g l-1 also achieved significant superiority of the same studied traits by giving it the highest averages of (1.6942%، 0.5194% ، 1.7564%، 10.556% ، 14.049%، 97.535 m kg-1، 46.321 m kg-1، 3.367 m g-¹ ، 34.779 m g-¹) and (29.029 cm ، 2.7524 mm ، 63.322 seedling leaf-1 ، 1537.95 cm2، 29.689 g ، 60.234 %) and (47.319 cm ، 2.6336 cm ، 26.461 cm3، 17.1118 g) respectively.
2. It achieved bilateral overlap treatment (Rootstock Volca mriana + coconut liquid 200 m L-1)significant superiority in the studied chemical qualities (nitrogen ، phosphorus ، potassium ، protein ، carbohydrates ، iron ، zinc ، total chlorophyll ، and ascorbic acid C) and vegetative traits (average length Stem، average stem diameter ، number of leafs ، leaf area) and root traits (root length ، root size ، dry weight of the root group) While there was no significant effect in the characteristic of dry weight of the vegetative total ، either in the characteristic of the relative moisture content of the leaves ، it outperformed together (sour orange + coconut liquid 200 m L-1) by giving it the highest average of (67.369%) ، as well as the treatment of (Rootstock Volca mriana + dry yeast extract at a concentration of 8 g L-1) .While there was no significant effect in the dry weight of the vegetative group ، either in the relative moisture content of the leaves، the treatment of (sour orange + coconut liquid 200 m.L-1) by giving it the highest average of (64.627%) ، while the treatment (coconut liquid 200 m L-1 + dry bread yeast extract at a concentration of 8 g L-1) achieved the highest averages in the qualities (nitrogen ، phosphorus ، potassium ، Protein ، carbohydrates ، iron، zinc ، total chlorophyll ، and ascorbic acid C) and vegetative traits (average stem length ، average stem diameter ، number of leafs ، leaf area ، dry weight of vegetative total ، relative moisture content of leaves) and root traits (root length ، root size ، dry weight of root group) ، but in the root diameter there was no significant effect of the spray gloss (coconut liquid 200 m L-1 + dry baking yeast extract at a concentration of 8 g L-1) .
3. Triple overlap treatment (Rootstock Volca mriana + coconut liquid 200 m L-1 + dry baking yeast extract at a concentration of 8 g L-1) achieved significant superiority in the studied growth qualities (nitrogen ، phosphorus ، potassium، protein ، carbohydrates ، iron ، zinc ، total chlorophyll and ascorbic acid C) ، vegetative traits (average stem length ، average stem diameter ، number of leafs ، leaf area ، dry weight of vegetative total) and root traits (root length، root diameter ، root size ، dry weight of the root group) achieving the highest averages of (2.1117%، 0.6867%، 1.9700%، 19.957% ، 136.275 m kg-1، 52.537 m kg-1، 4.999 m g-¹، 40.620 m g-1) and (38.833 cm ، 4.2033 mm ، 78.667 seedling leaf-1، 2398.67 cm2، 37.863g) and (57.580 cm ، 2.8673 mm ، 37.660 cm2، 21.8430 g-1) respectively ، in the percentage of protein there was no significant effect of the triple interference treatment (Rootstock Volca mriana + coconut liquid 200 m L-1 + dry baking yeast extract at a concentration of 8 g L-1) ، while triple interference treatment (sour orange + Coconut liquid 200 m L-1 + dry baking yeast extract at a concentration of 8 g L-1) ، The highest average relative moisture content of the leaves reached (70.315%).
