dubas bug, ommatissus lybicus de bergevin (hem.: tropiduchidae), is a key pest of date palms in iran.this pest was first reported on date palms in 1966 and has been established throughout the date producing regions in southern iran since. date palm is the only host plant of dubas bug. it attacks almost all date palm varieties, esp. mazafati variety in city of bam, kerman province and other vari...

The base temperature for germination of corn is approximately 10°C, which results in slow germination and emergence of corn crops sown into cool soils. The effects of plant-growth-promoting rhizobacteria (PGPR) and kinetin on grain and sweet corn emergence, plant growth and yield were studied under short season conditions in 1996 and 1997. Two PGPR strains (Serratia proteamaculans 1-102 and Ser...

Organic fertilizers have been used in agriculture to improve soil fertility, promote plant growth and protection which improves crop productivity. A field experiment was conducted order study the effect of organic (compost its water extract) on yield barley production. The results achieved showed that either compost (T3) or dual application with extract (T4) as biofertilizers increased most par...

a split plots experiment based on randomized complete blocks design was carried out at field research center of islamic azad university, shoushtar branch during 2012 to find out the suitable sowing date and urea fertilizer used in chamomile (matricaria recutita). main plots including three sowing date (9, 19 and 29 february 2012) and subplots including four levels of urea fertilizers (5, 10, 15...

introduction saffron as a winter active plant with low water requirement is the most strategic medicinal plant in arid and semi-arid parts of iran. this slow-growing plant has narrow leaves and no aerial stem, hence weeds can be overcome it. moreover, because of its root and canopy structure an important part of different resources is not used by this low input crop. therefore, the use of assoc...

introduction the study of growth parameters such as net assimilation rate (nar), leaf area ratio (lar), relative growth rate (rgr) and leaf area duration (lad) are important for analyzing yield constraints. the growth parameters can be used to understand the crop response to environmental variables during the growing season. the aims of the present study were to 1) consider the growth indices u...
