Cropping systems like organic farming, selling products at a higher price and promoting environmental sustainability by reducing fertilizer and pesticides, can be more profitable than conventional systems. An economic evaluation of three cropping systems in a seven year period experiment was performed, using a common rotation (fallow-barley-vetch-durum wheat) in a semi-arid rainfed field of Spa...
Background: Cotton with coevolving pests has been grown in India more than 5000 years. Hybrid cotton was introduced in the 1970s with increases in fertilizer and in insecticide use against pink bollworm that caused outbreaks of bollworm. Hybrid Bt cotton, introduced in 2002 to control bollworm and other lepidopteran pests, is grown on more than 90 % of the cotton area. Despite initial declines,...
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) success...
In order to study of agronomic, physiological characteristics, drought tolerance and to identify Agro-physiological traits associated with drought tolerance, 19 durum wheat genotypes consisting of 17 advanced breeding lines and two control cultivars (Saji and Zahab) were evaluated in a randomized complete blocks design with three replicated under both stress (rainfed condition) and non-stress ...
Wheat is mostly cultivated at rainfed condition in Iran, so, water deficit stress has much effect on yield reduction. Hence, breeding activities are necessary for introduction of wheat tolerant genotypes to water deficit stress. In order to estimate the heritability and genetic correlation between traits of 36 wheat genotypes, an experiment was conducted in two separate conditions (water stress...
