Organic fertilizers have been used in agriculture to improve soil fertility, promote plant growth and protection which improves crop productivity. A field experiment was conducted order study the effect of organic (compost its water extract) on yield barley production. The results achieved showed that either compost (T3) or dual application with extract (T4) as biofertilizers increased most parameters including straw well biological yield, number grains per spike grain income. With respect...
Cultivating cereals in monoculture systems contributes to the decrease grain yield and quality. Currently, under Mediterranean climate conditions of Tunisia, wheat mono-cropping covers more than 70% cereal areas. In order reveal impact this practice on productivity, five improved durum cultivars (Karim, Khiar, Om Rabiaa, Razzek, Maali) were conducted two previous crop: one-year crop (W) successive years (W-W). Then, they assessed for (GY), components (NKS, TKW, NS), straw yield, harvest...
Application of date palm waste compost is quite beneficial in improving soil properties and crop growth. However, the effect its application on microbial communities less understood. High-throughput sequencing quantitative real-time PCR (qPCR) were used to evaluate composition a barley field during tillering, booting ripening stages. The results showed that treatment had highest bacterial fungal abundance, significantly altered richness (Chao1 index) α-diversity (Shannon communities....
The implementation of conservation agriculture (CA) remains crucial for facing interannual variability in climatic conditions that impact durum wheat production and food security. current work was conducted to assess the effects tillage practice, previous crop, nitrogen (N) fertilization rate on agronomic economic performances rainfed a semi-arid environment Tunisia. Tillage practices included no-tillage (NT) conventional (CT). Preceding crops were either common vetch or bread wheat. N rates...
Wheat production in semi-arid area of Tunisia is limited by low rainfall (200-400 mm year-1), and the irregularity distribution precipitation intensification drought during cropping season. Therefore, irrigation proposed as alternative to improve maximize water-use efficiency (WUE) wheat. So, rational important for increasing crop yields decrease water use. The objective this study was investigate effects different levels on consumption, use total dry matter grain yields. conducted three...
Conservation agriculture based on no-tillage (NT) and crop rotation allows to enhance soil health. Based data collected from long-term trials in a semi-arid region of Tunisia, results showed that NT increased significantly organic carbon stock (SOCS), microbial biomass (SMBC), arbuscular mycorrhizal fungal (AMF) root colonization, respiration (CO2) at 0–20 cm topsoil layer compared conventional tillage (CT). Moreover, triennial (TRI), annual succession Faba bean-Durum wheat-Barley, biennial...
The aim of this paper is twofold. first objective to measure the technical efficiency mixed crop-livestock (CL) smallholder producers operating under conservation agriculture systems in Tunisian rainfed areas. second explore complementarities, synergies, and economies diversification across different production system components these using cross-partial derivative framework output variables distance function. A simple random sampling process was employed select survey 59 CL smallholders...
Abstract The Mediterranean region is facing major challenges for soil conservation and sustainable agriculture. Conservation agriculture (CA), including reduced disturbance, can help conserve soils improve fertility, but its adoption in the limited. Examining farmers’ perceptions of underlying sociocultural factors shed light on management practices. In this paper, we conducted a survey with 590 farmers across Morocco, Spain Tunisia to explore concepts that are cognitively associated...
This study aimed to determine the emissions of methane (CH4) and nitrous oxide (N2O) from seven Tunisian livestock species their evolution over eleven consecutive years (2008–2018). The animals used were cattle (dairy others), sheep, goats, camelids, horses, donkeys mules, poultry. estimations CH4 N2O based on Intergovernmental Panel Climate Change (IPCC) guidelines for national inventories, using Tier 1 2 approaches, with its default emission factors (EFs). approach was applied only...
The valorization of date palm wastes as bioresources has received little attention. In this context, the feasibility waste through composting and application effects on barley plants production under control condition was investigated. principal requirements for compost to be safely used are stability maturity that refer, respectively, microbial biomass activity's level, germination tests, plant growth bioassays or phytotoxicity. Indeed, phytotoxicity composted seed seedling researched....
<p>On-farm trial was conducted from 2005 to 2008 test the hypothesis that reduction of total dry matter (TDM) in crops can occur after a decreased radiation use efficiency (RUE) due shortage nitrogen and irrigation, we applied three irrigations treatments (D1, D2 D3) four rates (N1, N2, N3 N4). Photosynthetic active absorbed or cumulative light interception (PARabs) RUE Durum wheat were measured. Results showed D1N1 treatment recorded highest LAI, PARabs, TDM RUE. The maximum LAI...
Proteomic analysis was performed to investigate the differentially abundant proteins (DAPs) in barley roots during tillering stage. Bioinformatic tools were used interpret biological function, pathway and visualisation of network amongst identified proteins. A total 72 DAPs (33 upregulated 39 downregulated) among a 2580 response compost treatment, suggesting multiple pathways primary secondary metabolism, such as carbohydrates energy phenylpropanoid pathway, glycolysis protein synthesis...
Recent studies on agricultural water management in Tunisia report low productivity for some of the currently widely cultivated crops such as durum wheat. The objective this study is to estimate and marginal value irrigation wheat central Tunisia. We develop a production function, which revenue farmers per hectare expressed terms used volume addition other factors. function was estimated sample farms from Central Results show that 31.7% were applying volumes above economic optimal (more than...
Given the interest in mitigating consequences of soil deterioration and climate change impacts on durum wheat grain, objective our study was to evaluate effect two management systems - conservation agriculture (CA) conventional tillage (CT) grain composition nutritional value varieties (Karim Monastir) grown over cropping seasons (2018-2019 2019-2020).The system had an impact all studied parameters, namely 1000-kernel weight (TKW), proximate composition, energy value, total phenol content...
Due to the climate change situation, water deficit stress is becoming one of main factors that threatens agricultural sector in semi-arid zones. Thus, it extremely important provide efficient tools monitoring and early detection. To do so, a set Synthetic Aperture Radar (SAR) backscattering interferometric SAR (InSAR) Sentinel-1 data, covering period from January June 2016, are considered over durum wheat field Tunisia. We first studied temporal variation InSAR coherence data coefficient as...
The monitoring of cereal productions, mainly through yield estimations, has played an important role in providing reliable information to decision makers order ensure the proper management agricultural markets. In this context, remote sensing, which allows coverage large areas, is source that complements those obtained by other methods. study, we aim estimate wheat at early growth stage (spring season) using only one Radarsat-2 (RS-2) polarimetric image. We propose empirical statistical...
There is a growing interest in the Mediterranean regions to switch conservation agriculture (CA) address climate change and soil deterioration issues. The novelty of this study lies quality supply chain, from raw material (durum wheat grain) ready-to-sell product (spaghetti), under long-term CA, using two varieties over years study. This aims investigate impact management systems (SM) (CA after 10/11 (since 2009–2010) switching vs. conventional tillage (CT)) on grain quality, dough texture...
