Effects of salt stress on growth seedlings of two landrace varieties of durum wheat from the Tunisian centre (Triticum durum)

The seeds of two durum wheat landraces, in the centre of Tunisia, were evaluated at germination and seedling growth for tolerance to salt condition induced by NaCl at the same water potentials of 0.0, -0.3, -0.6, -0.9 and -1.2 MPa with the electrical conductivity (EC) values of NaCl solutions 0.0, 6.5, 12.7, 18.4 and 23.5 dSm-1, respectively. In this study, we studied the percentage of germination and the growth of root...

Effect of nitrogen and application ways of a plant biostimulant on different wheat genotypes contrasting in stature

Wheat (Triticum aestivum L.) is the leading crops for human nutrition in Europe and in most temperate regions worldwide. This crop is demanding in nutrients, among them nitrogen (N) is absorbed in higher amounts and its efficiency of utilization can be increased with a plant biostimulant use. The objective of this work was to evaluate the influence of different N levels and ways of biostimulant application on genotypes...

Regeneration of cotyledonary nodes from the recalcitrant melon cultivar ‘Gaúcho’

There is lack of suitable explants for efficient shoot proliferation in recalcitrant melon cultivars restricts genetic manipulation for crop improvement. In this study, we aimed to stimulate the regeneration capability of cells of melon (Cucumis melo L.) explants in order to increase shoot proliferation efficiency during regeneration. The media of seeds germination containing different concentrations of...

Determination of favorable sowing date of sweet sorghum in the State of São Paulo, Brazil by crop modeling

Sweet sorghum is a biofuel source for alternating with sugarcane in the State of São Paulo due to its short cycle, good sugar quantity and the possibility of using the same machinery that has been used for cane harvesting. The interest in the use of this crop is increasing because it keeps the sugar mills with material supply from all areas throughout the year. Thus we used an agrometeorological model to...

Evolution and prospects of the rice mill industry in Uganda

For the development of rice production in sub-Saharan Africa, it is critical to improve the quality of domestic rice produced and sold in the market. Being at the entry point in the upstream of the postharvest marketing chains, rice mills hold the pivotal position in the improvement of rice quality. Based on data collected from rice mills all over Uganda, this paper presents the evolution of the rice mill industry in...

Comparison of biometrical methods to describe yield stability in field pea (Pisum sativum L.) under south eastern Ethiopian conditions

Sixteen field pea (Pisum sativum L.) genotypes were evaluated using Randomized Complete Block Design (RCBD) with four replications for evaluating genotype x environment interaction (GEI) and yield stability across 12 environments during 2004 to 2006 at south eastern Ethiopia. The objectives were to compare various statistical methods of analyzing yield stability and to determine the most suitable parametric procedure to...

In vitro effect of two fungicides on pathogenic fungi causing root rot on tomato in Algeria

Tomato (Lycopersicon esculentum) is one of the most widely grown vegetables in the world. There is a growing concern in recent years, both in developed and developing countries, about the use of hazardous fungicides for controlling plant diseases. The in vitro effect of two fungicides commonly used in Algeria namely Trifidan and Antracol (propineb) on the growth of three pathogenic fungi of tomato, Fusarium oxysporum...

Negative effect of three commonly used seed treatment chemicals on biocontrol fungus Trichoderma harzianum

Successful integration of biocontrol organisms into agricultural production systems requires knowledge of their compatibility with commonly used pesticides. The compatibility of the biocontrol fungus Trichoderma harzianum (Eco-T ®) with a pesticide mix containing imidacloprid, metalaxyl and thiram (Product X) was assessed for maize seed treatment. Laboratory evaluations demonstrated that Product X caused up to 97.6%...
