This study aims to evaluate the forage quality and chemical composition of three halophytes, native in southern Tunisia : Salicornia emerici Duval-Jouve, Sarcocornia alpini (Lag.) Castrov. et Sarcocornia fruticosa (L.). Dry biomass (MS), organic matter (MO), mineral (MM) and crude protein (PB) contents, in vitro digestibility, ions and anti-nutritional compounds (flavonoids, tannins and saponins) were determined and compared to those of Medicago sativa (L.), considered as reference feeding plant. The obtained results indicate that dry biomass of these halophytes ranges from 10.50% to 18.63% for S. emerici and S. fruticosa, respectively. Compared to S. emerici, both halophytes recorded the highest percentages of organic matter and crude protein and higher concentrations of Na+, K+, Mg2+, Ca2+ and Fe2+. These three halophytes, harvested during the summer period, showed important digestibility percentages (> 70 % MS), exceeding those of alfalfa, and low levels of ADF, ADL and anti-nutritive compounds (condensed tannins, flavonoids and saponins). These findings suggest that the valorization of these native halophytes as fodder is promising, in particular S. alpini and S. fruticosa. This can provide many economic and environmental advantages in drylands.","PeriodicalId":16583,"journal":{"name":"JOURNAL OF OASIS AGRICULTURE AND SUSTAINABLE DEVELOPMENT","volume":"93 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73046484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these constraints, water deficit and heat stress are the main constraints limiting plant yield in the arid regions of the Mediterranean basin. Both of these abiotic factors are exacerbated by climate change. Fodder legumes provide a rich resource of plant nutrition to human diets, and are vital for food security and sustainable cropping. Numerous biochemical, molecular, and physiological responses are evoked by drought and heat stresses, influencing the fodder crop yield and nutritional value. When plants are water stressed, they are unable to maintain good growth and produce high yields. Drought also reduces the protein content of the plants, which can lead to a decrease in forage quality. Heat can negatively affect the productivity of forage legumes. High temperatures can cause heat stress which can lead to decreased photosynthesis and reduced productivity. In addition, high temperatures can result in decreased forage quality and increased nutrient losses. Exposure to combined water stress and heat can reduce the protein, fiber and mineral content of forage legumes and can also reduce their digestibility. This review summarizes the current status of the effects of drought and heat stresses on forage crops productivity and fodder quality.","PeriodicalId":16583,"journal":{"name":"JOURNAL OF OASIS AGRICULTURE AND SUSTAINABLE DEVELOPMENT","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74435428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, many of the desired agronomic traits in alfalfa are quantitative, and therefore improving them under abiotic and biotic stresses becomes an important goal in alfalfa breeding. One way to achieve such a goal is identification of loci that contribute to variation in complex traits. Genome Wide Association Studies (GWAS) provide advanced tools to identify genetic loci associated with traits of interest using high-density markers throughout the genome. In M. sativa, previous studies indicated that GWAS could identify numerous candidate single nucleotide polymorphism (SNP) markers for quantitative traits, including biomass, yield, forage quality, and drought/salt tolerance. Furthermore, mapping SNP markers against the M. sativa reference genome revealed many putative candidate genes which are associated with several cell wall-related traits. In this review, we summarize Genome Wide Association (GWAS) in alfalfa from concept to application and the identification and characterization of candidate genes for traits of interest.","PeriodicalId":16583,"journal":{"name":"JOURNAL OF OASIS AGRICULTURE AND SUSTAINABLE DEVELOPMENT","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81537702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we analyzed the genetic diversity of Hordeum marinum, genotypes originated from Soliman Sebkha in response to salinity (0, 250 and 400 mM) by measuring a set of parameters related to growth, water statue and photosynthetic activity. Results of ANOVA showed that variability of measured parameters was explained by the effects genotypes, treatment and their interaction, with treatment factor recorded the highest values. Salinity significantly reduced the photosynthetic rate and related parameters, including stomatal conductance (gs), intercellular CO2 concentration (Ci), and transpiration (E). Several indices for salt tolerance indices comprising tolerance index (TOL), stress tolerance index (STI) and Salt Tolerance (ST) were calculated based on drought biomass (ADW) under non-stressed and under stress conditions. Results showed that lower values of TOL and higher values of ST and STI indicate the superiority of the genotypes having enough plasticity to respond to extreme conditions. Principal Component Analysis clustered genotypes into sensitive (21.43%), moderately tolerant (50%), and highly tolerant (28.57%) groups, depending on their relative potential to sustain good growth under high salinity. Results indicating sufficient genetic variability for salinity tolerance among the studied genotypes, hence tolerant genotypes can be good candidates in future breeding programs.","PeriodicalId":16583,"journal":{"name":"JOURNAL OF OASIS AGRICULTURE AND SUSTAINABLE DEVELOPMENT","volume":"17 2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83152776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The need for sustainable agricultural alternative systems is prompted by economic, environmental and biological perspectives. Producers require cultivation methods that minimize environmental damage while simultaneously preserving and improving farm profitability. One of the key solutions is intercropping. Which is a cropping system where the crop can coexist in the same soil and can be irrigated simultaneously at the same time. It is used to improve crop yields, land use rates, as well as to reduce the barriers towards sustainable cultivation and the development of disease and insect pests as well as control weed growth. Besides, intercropping of legumes in a cropping system provides advantages for non-legumes due to improved nutrient distribution, to improved soil biology and to enhanced use of available resources. The biological fixation of nitrogen by legume crops makes intercropping legumes, especially alfalfa, a cost-effective solution to the problem of using artificial fertilizers. Alfalfa intercropping does not only meet the requirements of food security and forage needs, but also preserves the eco-environment, which has made this cultivation model a very promising one for agricultural development under environmental constraints.","PeriodicalId":16583,"journal":{"name":"JOURNAL OF OASIS AGRICULTURE AND SUSTAINABLE DEVELOPMENT","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83350654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the development of these geothermal potentials is necessary to ensure their sustainability. The present work aims at characterizing the return water and assessing its impact on greenhouse crops and oasis systems. The study was based on physico-chemical analyses of return water collected from nine geothermal poles spread over the three governorates (Gabes, Kebili and Tozeur), field visits and surveys conducted with farmers. These physico-chemical analyses indicate a poor to average water quality with a very high saline risk and a medium alkaline risk. Indeed, the salinity of the water varies from 2.6 to 11.9 g/l and the SAR from 5.1 to 8.8. In addition, the salinity management techniques adopted by farmers are still limited due to their low financial capacity.","PeriodicalId":16583,"journal":{"name":"JOURNAL OF OASIS AGRICULTURE AND SUSTAINABLE DEVELOPMENT","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91061561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
