Algeria's vineyards: an Islamic dilemma and a problem of decolonisation.
Abstract Algeria's viticultural industry represents an example of the way a colonial legacy can turn into a problem of dependency, the solution to which represents an issue of decolonisation and adjustment. An added dimension is the cultural inappropriateness of viticultural production in an increasingly Islamic country. By late colonial times Algeria's wine exports represented over half of its exports by value. To add economic independence to political independence threatened serious financial and employment losses, so any opportunity to avoid the reconversion of the now culturally inappropriate vineyards seemed attractive. Eventually, with the growth of hydrocarbon revenues, the reconversion and reconstitution of Algeria's vineyards proved possible during the 1970s. However, 20 years after independence, Algeria still had nearly half the 1962 area of vineyards, though with markedly lower yields and marketing at lower prices. The colonial legacy has now turned into an economic liability and has been tackl...
Le produit agricole algérien
Ce travail tente, a partir des statistiques agricoles officielles, d'evaluer le produit agricole brut algerien, et d'en analyser la ventilation a travers les 10 branches de production, les 31 wilayate, et les deux secteurs juridiques. Il met en evidence le poids relatif de la production animale, l'heterogeneite tres accusee a tous les plans, une differenciation juridique l'emportant sur les differenciations geographiques elles-memes.
Effect of Soybean Cyst Nematode (Heterodera glycines) on Yield of Resistant and Susceptible Soybean Cultivars Grown in Ohio.
Soybean (Glycine max) producers in Ohio rarely use soybean cyst nematode (Heterodera glycines, SCN)-resistant cultivars because of concerns over limited yield potential and lack of resistance to Phytophthora sojae. A two-year study was initiated to determine grain yield and nematode population increase on soybean cyst nematode-resistant cultivars in maturity groups II and III in production fields. Sites differed in soil texture, nematode densities, and P. sojae infestation at a number of locations in Ohio. Soil was assayed for nematode densities before planting and at harvest. Yields of resistant cultivars averaged 0% to 18% higher than those of susceptible cultivars in fine-textured soils with average preplant populations ranging from 463 to 14,330 SCN eggs/100 cm(3) soil. In coarse-textured soils, yields of susceptible cultivars were 21% to 56% less than the resistant cultivars with average preplant densities ranging from 1,661 to 15,558 SCN eggs/100 cm(3) soil. The reproductive index ranged from 0.1 to 5.5 for resistant cultivars and 0.4 to 112 for susceptible cultivars. In 1993, yield of P. sojae-susceptible, nematode-resistant 'Asgrow A 3431' was as high as yield of the P. sojae-resistant, nematode-susceptible cultivar 'Resnik' in a Phytophthora-infested field. The nematode-resistant cultivars Madison Experimental 131527 and Asgrow A3431 had higher yields than AgVenture AV1341 and susceptible cultivars Resnik and Kenwood when compared over five nematode-infested sites. Nematode-resistant cultivars were found to be excellent alternatives to currently grown susceptible cultivars for managing SCN where group III cultivars are used. However, better cultivar alternatives may be needed for sites with combined Phytophthora root rot and cyst nematode problems.
