This study assessed the suitability of two potato varieties, Riviera and Argana, for storage under foliar sprinkling with calcium and magnesium fertilizers at four concentrations: 0% (serving as the control), 0.5%, 1% calcium chloride, and 0.4%. Magnesium sulphate) was sprayed at three concentrations (0, 250, and 500 mg L-1) with malic acid. The findings of the study revealed that the Riviera variety exhibited noteworthy advantages in weight reduction, hardness, and alpha-amylase enzyme activity when compared to the Argana variety. On the contrary, in terms of total sugar content and pectinase enzyme activity, the Argana variety exhibited a marked advantage over the Riviera variety. Weight loss and the activity of pectinase and alpha-amylase enzymes were found to be significantly enhanced in the control treatment compared to the other spray treatments, respectively, upon the addition of magnesium sulfate and calcium chloride. However, hardness and sugar content did not differ significantly. In addition, the administration of 500 mg L-1 malic acid resulted in the least amount of weight loss reduction.

Two different potato varieties, "Riviera" and "Argana", were used in this study to evaluate the influence of foliar fertilization with calcium and magnesium at four concentrations (0% control, 0.5% and 1% calcium chloride, and 0.4% magnesium sulfate), as well as foliar spraying with malic acid at three concentrations (0, 250, and 500 mg L-1). The experiment was conducted in the vegetable field of the Department of Horticulture and Landscape Design at the College of Agriculture and Forestry during the spring growing season of 2022. The study employed a complete randomized block design with three replications. The findings demonstrated that the two categories differed significantly. In comparison with “Argana”, “Riviera” showed a significant advantage both in soluble solids content and tuber hardness, at the same time “Argana” was significantly superior to “Riviera” in the total sugar content and tuber magnesium content. The treatment of foliar spraying with a high concentration of calcium chloride and magnesium sulphate a significant difference with the control in the Re – magnesium – percentage in tubers. Also, the application of 500 mg L-1 of malic acid as the treatment was better than the control concerning the percentage of calcium in the tubers. The treatment with 250 mg/L of malic acid did not differ significantly from the control, while the lower sugar content was preferred in the „Rivera‟ cultivar without calcium and magnesium treatment and with the treatment of 500 mg/L of malic acid; however, the response was lower in the „Susina Precoce‟ cultivar, with its best result obtained with the treatment of The highest tuber hardness was found in variety “Riviera” treated with 250 mg L-1 of malic acid while the lowest in variety “Argana” also treated with malic acid at the same concentration. The highest percentage of calcium in tubers was found in the “Rivera” variety treated with 500 mg L-1 malic acid, while the “Argana” variety treated with 250 mg malic acid and 0.5% calcium chloride obtained the lowest percentage. The highest magnesium content in tubers was observed in the “Argana” cultivar treated with 0.5% calcium and 500 mg/L malic acid, while the lowest was in the comparison treatment for both cultivars.

Two different potato varieties, Riviera and Argana, were used in this study to evaluate their performance under the influence of foliar fertilization (calcium and magnesium) at four concentrations (0%, 0.5%, and 1% calcium chloride, and 0.4% magnesium sulfate) and foliar spraying with malic acid at three concentrations (0, 250, and 500 mg L-1) in the vegetable field of the Department of Horticulture and Landscape Design at the College of Agriculture and Forestry during the spring growing season of 2023. The study was conducted using a complete randomized block design with three replicates. Argana variety showed significant superiority over Riviera in traits such as plant height, leaf area, average tuber weight, and yield per plant, while Riviera variety outperformed Argana significantly in the number of aerial stems. The best yield per plant for Argana variety was obtained with 0.4% magnesium sulfate and 250 mg L-1 malic acid treatment, while the best plant height was achieved in the same variety with 0.4% magnesium sulfate and 500 mg L-1 malic acid treatment. The highest number of stems was observed in Riviera variety with 0% calcium chloride and 500 mg L-1 malic acid treatment, while the lowest was in Argana variety with 0.5% calcium chloride and 250 mg L-1 malic acid treatment. The highest leaf area was found in Riviera variety treated with 0.5% calcium chloride and 0 mg L-1 malic acid, while the lowest was in the control treatment of the same variety. The highest average tuber weight was recorded in Argana variety with 0.5% calcium chloride and 250 mg L-1 malic acid treatment, while the lowest was in Riviera variety with 0% calcium chloride and 250 mg L-1 malic acid treatment.

Many soils, especially Iraqi soils, contain pH The high level contains many nutrients, but it is not ready for absorption by the plant, and thus symptoms of deficiency appear on the plants gown in those soils, but when adding biofertilizers that contain beneficial microorganisms, it works to reduce pH These soils and thus increase the readiness of the nutrients present in them, which reflects positively on the characteristics of the root, vegetative and fruitful growth of the cultivated plants, and from this standpoint it is possible to reduce the use of excessive chemical fertilizers and compensate for them with biological fertilizers and preserve human health and the environment around us

EFFECT OF DIPPING IN HOT WATER AND ASCORBIC ACID AND MODIFIED ATMOSPHERE PACKAGING ON STORABILITY OF SOUR ORANGE

المجلة: 4th International Agricultural Conference 10-11 January 2023

سنة النشر: 2023

تاريخ النشر: 2023-11-01

Fully mature, orange to red color, medium-size fruits of sour orange were manually harvested from the trees early in the morning on 27/1/2022 from a private orchard in Baghdad governorate\ Iraq, and transported to the Central Laboratory, College of Agricultural and Forestry. Sound sour orange fruits with similar size and appearance were divided into two groups randomly. Each group contained 450 fruits for sour orange, and each group divided into 9 subgroups for the dipping and interaction treatments. The dipping treatment started by dipping sour orange fruits in ascorbic acid concentrations (0, 1% and 2%) for 2 minutes, and left them to dry until the following day, then the sour orange fruits were dipped in the hot water (20, 40 and 50°C) for 5 minutes, and left them to dry until the following day, after there, the packaging treatment were conducted. The fruits were stored in the cold room at 5°C and 80-90% RH. the imperforated bags decreased fruit weight loss, the hot water dipping resulted in a significant total sugars, and the ascorbic acid treatments gave the highest total soluble solids an ascorbic acid contents of the fruits as resulted with control treatment. The interaction between the treatments improved the studied traits.

This study was carried out in the cold room at a private orchard in Sada & Baweza in Mosul. Two local cultivars "Bashiqi" and "Khastawe" were used., green fruits were harvested before it began to coloring. The fruits harvested from olive trees, 10 years old for both cultivars, on 15/10/2017 (green fruits). After the process of sorting, cleaning and washing with water to remove dust from them, and exclude the affected fruits and the small fruits, and left to dry, then subjected the fruits to the precooling in the cold room at 12 C˚ for the entire day, and then extracted and weighed in a sensitive balance, the green (1 kg) per sample. Then the fruits were packed in perforated polyethylene bags and non-perforated, tightly tied, and stored in the cold room randomly at 6 ±1 C˚ and relative humidity 85-90 %. The two cultivars didn‘t differ significantly in weight loss, soluble solids, and decayed fruits, while the highest percentage of oils was in the cultivar "Bashiqi,. The percentage of violet colored fruits of cv. "Khastawe" fruits reached 100%, but not in "Bashiqi" fruits. The weight loss of fruits in non-perforated bags was significantly lower than fruits in perforated bags, also fruits were significantly superior in non-perforated bags than fruits in perforated bags in total soluble solids. Packaging the fruits in perforated bags significantly reduced the percentage of decayed fruits. There were no significant differences between the method of packaging in the oil percentage of the fruits. Weight loss increased steadily as storage period prolonged, and the highest was in fruits which stored for 70 days, while total soluble solids was the lowest at the same storage period i.e. 70 days. Prolonging storage period to 70 days resulted in an increase in decayed percent of fruits, while significantly highest oil percent was in 30 days stored fruits. The less of loss weight was for fruits cultivar "Khastawe" that packaged in non-perforated bags stored for 30 days which gave the higher ratio of TSS, while oil percent was the best in "Bashiqi" cv. Fruits which packaged in non-perforated bags for 30 days. Highest colouration of fruits was was of "Khastawe" cv. Fruits packaged in perforated bags for 70 days.
