RP-effect of adding whey and spraying with silicone on the growth and yield of Chinese Cabbage plant.pdf

The experiment was conducted in fields of horticulture and landscaping of College of Agriculture – University of Karbala for agricultural season
2022-2023 with aim of knowing the effect of spraying treatment with silicon in the form of potassium silicate (k2sio3) and addition of whey by-product in improving growth indicators and yield of Chinese Cabbage plant.
The experiment included 16 factorial treatments that included four concentrations of silicon (0.1.2.3) ml L-1 and four concentrations of whey by-product (0.8.16.24) L. Hectare -1 and be in three installments، between one batch and last 10 days. It was implemented as a factorial experiment with two factors according to randomized block design and with three replications، and least significant difference test (l.s.d) was used to compare averages at the probability level of 0.05.
The treatment with silicon at a concentration of 3 ml L-1 showed a significant increase in the vegetative growth indicators in the plant height، which reached 53.72 cm. Plant-1 and leaf area was 76.98 cm2. Plant-1 and the weight of the plant was 1733 g. Plant-1 has 26.36 leaves. Plant-1، as well as the dry weight of 39.52 g. Plant-1 and the average weight of the marketing head is 1342 g. plant-1، with a total yield of 102.97 tons. ha-1 and the marketing yield is 69.12 tons. HA-1 has a marketable life of 4.716 days. Plant-1 As for the treatment with the whey yield، concentration was 24 liters. Ha-1 was significantly superior in all plant heights، which reached 50.91 cm. Plant-1، and the leaf area was 70.26 cm2. plant-1 and the weight of plant was 1646.4 g. For a plant-1 number of leaves is 25.51 leaves. plant-1 and the average weight of the marketing head which reached 1318 g. plant-1، with a total yield of 9763 tons. ha-1 and the market yield، which amounted to 67.89 tons. ha-1 and a marketable life of 3.77 days. Plant-1 of plant and there was no significant difference in dry weight
The two-way interaction between the two experimental factors showed a significant superiority in all the vegetative growth traits، plant height، which reached 56.93 cm. Plant-1 and leaf area was 78.60 cm2. Plant-1 and the weight of plant was 1777.7 g. Plant-1 has 26.80 leaves. plant-1 and average weight of the marketing head which reached 1354 g. plant-1، with a total yield of 105.42 tons. ha-1 and the market yield، which amounted to 69.74 tons. ha-1 and a marketable life of 4.93 days. Plant-1 of plant significantly increased dry weight at a concentration of 2 ml. 1 liter of silicone and in addition to 24 liters. Hectare-1 of whey، which amounted to 39.53 g. plant-1
The spraying treatment with silicone led to a significant increase in some chemical properties، as the concentration exceeded 3 ml. L-1 was significantly increased in each of the total chlorophyll، which amounted to 2.903 mg 100 gm-1، percentage of nitrogen، which amounted to 2.719، percentage of phosphorus، which amounted to 0.371، the percentage of potassium، which amounted to 1.540، and the percentage of protein، which amounted to 16.99، ascorbic acid was 65.37، and the percentage of dissolved solids Which amounted to 4.39، while the concentration of 2 ml L-1 had a significant effect on each of the carbohydrates، which amounted to 58.70، and the percentage of nitrates، which amounted to 0.426. As for the treatment by-product (whey)، the concentration was 24 liters.ha. nitrogen amounted to 2.547، the phosphorus percentage amounted to 0.316، potassium percentage amounted to 1.403، protein amounted to 15.91، the ascorbic acid amounted to 64.61، percentage of dissolved solids amounted to 4.04، percentage of nitrates amounted to 0.469، and percentage of carbohydrates amounted to 57.00، except for chlorophyll، which excelled with comparison equation، which amounted to 2.872 amalgam 100g-1
The bilateral interaction between the two experimental factors showed a significant superiority of a concentration of 3 ml L-1 of silicon per 24 L hectare-1 of whey in percentage of nitrogen، which amounted to 2.820، percentage of phosphorus، which amounted to 0.386 percentage of potassium، which amounted to 1.667 percentage of protein، which amounted to 17.625، and ascorbic acid، which amounted to 69.25. dissolved solid، which reached 4.47، was superior to carbohydrates and nitrates at a concentration of 2 ml. L-1 of silicone is 24 liters. Ha-1 was 58.70 and 0.581، respectively، while chlorophyll was significantly superior at a concentration of 2 ml. L-1 of silicon without addition، which amounted to 2.976 mg 100g-1
