The result showed that firmness, colour(∆E*) and soluble solid content (SSC) in fresh-cut peaches treated with 20 g L -1 SPI + 10 g L-1 CaCl2 were higher than control. Compared with other treatments, treatment with 20 g L-1 SPI + 10 g L-1 CaCl2 2 significantly decreased weight loss rate, bacterial growth, respiratory rate and ethylene emission of fresh-cut peaches. Treatment with 20 g L-1 SPI + 10 g L-1 CaCl2 also inhibited increase in browning degree, production of reactive oxygen species, malonaldehyde and total phenols, and maintained higher activities of superoxide dismutase and catalase, whereas inhibited the activities of peroxidase and polyphenol oxidase.

The mechanical, fuel, and quality properties of these briquettes were investigated. The results showed that the leaf fronds had the best results in terms of mechanical properties and fuel quality properties of the briquettes. The best results for compressive stresses for the leaf fronds were 24.98 MPa at 10% moisture content and for the whole fronds were 4.27 MPa at 12%. The second storage period gave the best results for all briquettes at the different moisture contents. The results showed significant effects of moisture content and storage period on mechanical properties. The hydrolysis time and durability of the briquettes increased with increasing moisture content. The calorific value of leaf fronds and whole fronds briquettes ranged between (17.78 and 18.12 MJ/kg) and (16.54 and 17.78 MJ/kg), respectively.

This study investigated the response of three Bt cotton hybrids in comparison to their conventional non-transgenic version (near-isogenic lines) along with two locally adapted genotypes for growth, yield attributes, phenological characteristics and rooting behavior. Therefore, two experiments were conducted during summer season of year 2016 and 2017 to evaluate differences among 3 popular Bt cotton hybrids along with their non-Bt version. First field experiment was conducted as a pot study wherein shoot and root parameters of 3 Bt cotton hybrids (Ankur 3028, MRC 7017, Bioseed 6588) were compared with their non-Bt version along with 2 local checks (i.e.,hirsutum cotton Cv. F2228 and arboreum cottonCv. FDK124). Second field experiment evaluated growth, phenological characteristics, yield attributes and productivity potential of above mentioned Bt and non-Bt hybrids. Findings of pot experiment could not establish any significant difference among studied Bt and non-Bt hybrids for root and shoot characteristics. However, arboreum cotton FDK124 exhibited higher root length than all genotypes. Results of second experiment revealed significant differences for phenological characteristics, wherein Bt version of all the tested hybrids exhibited earliness for flowering initiation, 50 % flowering and days to maturity over their non-Bt version. Seed cotton yield (SCY) in all hybrids possessing Bt gene was significantly higher than their non-Bt version primarily due to higher bolls plant-1. Studies conclude that introgression of Bt gene could not alter rooting parameters of evaluated cotton genotypes but significantly affected phenological stages by inducing earliness and higher SCY in Bt versions due to improved bolls plant-1.\u0000Keywords: Bt cotton; Near-isogenic lines; Phenology; Root dry matter; Seed cotton yield","PeriodicalId":11648,"journal":{"name":"Emirates Journal of Food and Agriculture","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43576856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to ion accumulation, salinity stress results in lowering growth rate and water uptake. This issue is being solved by the use of several plant growth regulators. Plant growth regulators have been proven to increase plants' ability to withstand against stress. In this study, turnip (purple top cultivar) was subjected to four distinct levels of salt (0, 4, 8, and 12 dS/m), as well as one level of gibberellic acid, in order to assess the function of exogenously applied plant growth regulator glutamic acid (GA) (10 mM). Results revealed that salt stress slowed plant growth and decreased the amount of chlorophyll in turnip leaves. Application of salt alone resulted in a considerable decline in biochemical characteristics. However, in salt-stressed conditions, exogenous application of GA improved the antioxidant activity, chlorophyll contents and plant growth in the turnip leaves. Moreover, results depict that under salt stress vitamin C decreased; however, exogenous application of GA enhanced the Vit. C in turnip plants. Further, the uptake of salt content in turnip roots and leaves was significantly lowered by the application of GA. Additionally, under salt stress; GA dramatically controlled the quantity of phenolic compounds in turnip. \u0000Keywords: Brassica rapa, Salinity, Glutamic acid, Morphological and biochemical assay, Reducing and non-reducing sugar","PeriodicalId":11648,"journal":{"name":"Emirates Journal of Food and Agriculture","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2023-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49608459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this work is to evaluate the effects of different organic amendments (OA) on any physico-chemical properties of the soil such as: pH, electrical conductivity (EC) and organic matter (OM). The amendments are: palm compost and manure (CPM); palm compost and reed (CPR); palm compost and reed + manure (CPRM); ovine manure (Om) and unamended soil (Ctl). The choice of materials is based on the idea of valorizing palm groves waste (palms and reeds) with ovine manure. The trial is conducted on randomized complete block design where two levels of soil samples are taken two months apart: S0 (day zero), Sin (initial sampling before application of amendment) then, S1, S2 and S3 until the end of cropping cycle. Obtained results show that all different OA increase the pH and decrease the EC of the soil after two months of application (S1) compared to the value of the initial sampling (Sin), which demonstrates the very highly significant effect of time on both parameters in the surface horizon. For the OM an incessant increase during the assay period was noticed where Om and CPR have marked the highest values during the third sampling (S3). This proved that the prepared composts from oasian wastes have an effect in improving soil properties over time.

These two processes are the result of the rise of the water table caused by the overdose of irrigations. To counteract soil degradation and restore field productivity, the oasis farmers turn to use sandy and manure amendments. Therefore, three treatments (Control (C), sandy amendment (T1) and combined amendments composed by sand and manure (T2)) has been applied in Nefzaoua oasis to evaluate the effect of different amendments on oasis soil fertility, irrigation parameters, and barley yield. Results showed that T2 enhanced yield parameter (3,07 t/ha) compared to control treatment (1.85 t / ha) thanks to the improvement in the total nitrogen concentration (1.38 g kg -1), soil organic carbon (28.74 g kg- 1) and therefore C / N ratio (20.78) for T2 treatment at the level of the 0-20 cm layer. The results revealed that sand + manure combination (T2) enhanced the irrigation dose that can be effectively applied for the barley plants (19.61 mm) compared to the control treatment (15.49 mm) and T1 treatment (12.26 mm).
