in order to obtain the maximum benefit, yield increasing and its stability a supplemental irrigation field experiment was conducted as split plot arranged in a randomized complete block design (rcbd) with three replications during 1999-2002 at maragheh agricultural research station of dari. the treatments included four levels of irrigation (average of three years: 0, 95, 151 and 207 mm) as main...

Post-anthesis drought stress is the most important problem affecting wheat production in dryland fields, specially in Mediterranean regions. The main objective of this research was to evaluate drought tolerance indices in dryland wheat genotypes under post-anthesis drought stress. The research was including two different experiments. In each experiment, twenty dryland bread wheat genotypes were...

Saffron is grown in arid and semi-arid regions in Iran in late autumn, winter and late spring with rainy season. It should be irrigated by supplemental basin irrigation. Since rainfall is usually delayed in autumn, therefore, a pre-flowering irrigation of about 100 mm is needed. In areas with a seasonal rainfall of 600 mm a post- flowering irrigation of about 50 mm is adequate for economical yi...

to investigate the effect of plant density and supplemental irrigation on agronomic characteristics, chlorophyll content and light interception beneath the canopy of three chickpea genotypes under dryland conditions, an experiment was conducted at research station of lorestan agricultural research center located at chegini, khoramabad, during 2004-2005. the study was conducted using a split-spl...

High-density apple (Malus domestica) orchard management techniques and productivity were evaluated on an old orchard replant site in North Carolina. Trees were planted at 5 × 10 ft (1.5 × 3.0 m), giving a tree density of 871 trees/acre (2152 trees/ha). Well-branched ‘Smoothee Golden Delicious’ trees on ‘Mark’ rootstock were planted in 1990. Orchard-management factors which increased cumulative ...
