Effect of potassium and calcium upon the yield and fruit quality of Cucumis melo
The aim of this work was to study the effect of potassium and calcium in combination with nitrogen upon the yield and fruit quality of outdoor-grown melon (Cucumis melo L.). Two experiments were simultaneously performed through the use of two cultivars: âHoney Dew Green Fleshâ (Inodorus group) and âSivanâ (Charentais group). A completely randomized experimental design was used with nine treatments resulting in a factorial arrangement of 3 x 3 due to the use of three doses of K and three doses of Ca. Doses were administered through fertigation with the injection of the fertilizers into a drip irrigation system, expressed as follows in relation to N: N:K (1.8:1.0 â 1.0:1.0 â 0.0:1.0) and Ca:N (2.0:1.0 â 1.0:1.0 â 0.0:1.0). Fertilization with nitrogen and phosphorus was the same in all treatments, through the application of an equivalent of 160 kg ha-1of N and 45 kg ha-1 of P. Yield (Mg ha-1) was measured as well as fruit quality attributes: firmness (kg); pulp or mesocarp thickness (mm) and rind thickness (mm); and total soluble solids (%). Differences were observed between the two varieties. The application of K showed the greatest effect on the quality and yield of the harvested fruit. However, this effect was not observed with Ca
Plant Tolerance Mechanisms to Soil Salinity Contribute to the Expansion of Agriculture and Livestock Production in Argentina
This chapter addresses salt tolerance mechanisms in crops and woody species cultivated in Argentina, highlighting the contribution of local research to these topics. Work on forages and woody species represents approximately half of this research that has been published by Argentine authors in international journals. Basic research on plant salinity mounts to only 12% of the total, indicating that it still does not attract sufficient consideration among researchers. Among forage plants, attention in this chapter is focused on Rhodes grass (Chloris gayana Kunth), while in woody perennials, salt tolerance mechanisms in Prosopis, which have been extensively investigated locally, are reported. Despite the importance of soybean in Argentine economy, as well as that of other crops such as maize, wheat, sunflower, relatively little research attention has been paid to salinity issues in these major field crops. This situation may reflect the fact that they are mostly cultivated in non-saline soils.Instituto de FisiologĂa y Recursos GenĂ©ticos VegetalesFil: Taleisnik, Edith.

Ecological restoration and productive recovery of saline environments from the Argentine Monte Desert using native plants
The accumulation of soluble salts in soils is one of the main environmental factors that contribute to the loss the productive capacity of ArgentinaÂŽs arid ecosystems. Salinizacion processes, lead to critical states of degradation and desertification. The challenge to recover and improve the productivity of such degraded areas is complex because it should consider restoration strategies that will be integrated with local economic, cultural and social activities. The integrative use and management of different native species in remediation programs is an attractive restoration tool that could improve the productivity capacity of degraded areas. Native species have developed numerous strategies and adaptations that could ensure their survival in saline environments. Nevertheless, species selection, management and appropriate technologies to be used in afforestation programs may be limited because we do not know in detail both the potential and needs of each native species and the environmental characteristics of each site. In this chapter we analyze not only the problem of soil salinization and the challenge of restoring saline environments in Argentina, but also the characteristics of native species of trees, shrubs and grasses of the Monte region, considering their tolerance to saline stress and the provision of goods and services to local populations, which can be useful in restoration programs.Fil: Villagra, Pablo Eugenio.
