This research was conducted on mature pomegranate (Punica granatum L. “Wonderful”) trees growing at a site located in North Coast, Matrouh Governorate, Egypt. The aim was to investigate the impacts of different irrigation regimes in combination with different fertilizer regimes on the fruit set, fruit retention, yield, and nutritional status of the trees. The experimental factors were arranged in a split-plot design, with four replicates per treatment combination. The results indicated that all of the characteristics measured, including leaves nutritional status, percentages of fruit set, fruit drop, fruit retention, fruit cracking, fruit sunburn, and marketable fruit, and yield were significantly affected by the interaction between the irrigation treatment which denoted by percentages of reference evapotranspiration (ETo) and fertilizer regime. The application of 75% mineral fertilizer + 25% organic manure under deficit irrigation of 80% ETo increased the yield by an average of 18.23% over the 2 years compared with 100% mineral fertilization under full irrigation, while 50% mineral fertilizer + 50% organic matter under 80% ETo gave the maximum percentage of marketable fruit (86.23% and 86.84% in 2018 and 2019, respectively). The maximum water use efficiency was obtained with the 80% ETo treatment combined with 75% mineral fertilizer + 25% organic manure in both seasons with values of 9.69 and 10.06 kg/m3 applied water, respectively. These results demonstrate that under the field conditions at the experimental site, the fruit set and retention could be improved by applying a reduced amount of mineral fertilizer in combination with organic manure and less irrigation water.

Individual and interaction effects of plant growth regulators and fertigation on quality of pomegranate were investigated. Maximum mean polar diameter (9.59 cm), equatorial diameter (8.10 cm), fruit weight (206.06 g),fruit volume (190.86 cc), number of arils per fruit (416.81), aril weight per fruit (146.35 g), weight of 100 arils (35.86 g) and aril per cent (70.92 %) along with minimum specific gravity (1.090), rind thickness (5.15 mm), rind per cent (29.09%) and fruit cracking (5.58%) were recorded in F2 (100 per cent RDF through fertigation). Similarly, spray of 100 ppm NAA (N2) and 250 ppm ethrel (E2) significantly influenced the above characteristics of fruit. Treatment combination of 100 ppm NAA + 150 ppm ethrel + 100% RDF through fertigation (N2E1F2) gave better quality fruit over other treatments including control. Bangladesh J.

Controlled atmosphere (CA) storage has been observed to prolong the shelf life of fresh produce. The objective of this study was to determine whether CA storage performed better than regular air (RA) storage in maintaining fruit quality of six pomegranate (Punica granatum L.) cultivars grown in the state of Georgia. Pomegranate fruit produced in Ty Ty, GA in 2010 and 2011 were stored in CA [5% CO2 + 3% O2, 5 °C, 90% to 95% relative humidity (RH)] or RA (5 °C, 90% to 95% RH) for 3 months. Pomegranate whole fruit and juice were evaluated for various physical and chemical attributes at the end of storage. Fruit differed by cultivar for rind smoothness, fruit cracking, disease incidence, and chilling injury (CI). Fruit stored in CA had a smoother and less shriveled rind, lower CI, fewer disease severity symptoms, and thus better quality than fruit stored in RA. Fruit rind color, total soluble solids (TSS), titratable acidity (TA), and anthocyanin content in fruit juice were unaffected by storage method. The results showed that pomegranate fruit quality was better sustained under CA compared with RA storage.

Punica Granatum L

Pomegranate (Punica granatum L.) is a tropical and subtropical climate plant with high economic value and nutritional content. Having valuable phytochemicals in terms of health caused an increase in demand for pomegranate consumption and this situation accelerated pomegranate production. However, global warming and climate changes are among the factors limiting the production of pomegranate. Especially abiotic stress factors caused by adverse ecological conditions cause significant economic losses in pomegranate production. Drought stress, which is one of these negativities, causes fruit cracking problem, which is one of the important problems in pomegranate production. Minimizing the fruit cracking problem, which causes economic losses, is possible by breeding varieties that are resistant to under non-irrigated conditions. Determining the resistance of the cultivars to be used in breeding programs against fruit cracking will allow the development of elite cultivars. For this purpose, it was aimed to determine the fruit cracking rates of 30 different pomegranate genotypes in the Pomegranate Genetic Collection of Çukurova University, Faculty of Agriculture, Department of Horticulture, under non-irrigated conditions. A correlation was made between the cracking rates of the genotypes and the amount of soluble solids content (SSC). According to the correlation analysis between the cultivars, there is no statistically significant difference between the SSC and the cracking rate. However, a weak negative correlation was determined between SSC-cracking rate (-0,1132). In the light of the pomological data obtained, it was determined that 8 pomegranate genotypes grown under non-irrigated conditions had a fruit cracking rate of 40 % - 85 %, cracking rates were below 10 % in 8 pomegranate genotypes and no fruit cracking was observed in 6 genotypes. As a result of the analysis, it was observed that drought stress was effective on the fruit cracking rate or the exacerbation of the fruit cracking rate, but the resistance level of some genotypes against the fruit cracking problem was high.
