plant density affects yield components and seed yield by influencing the changing vegetative growth and environmental resources. these effecting factors were studied in the spring of 2006 at ramin agricultural research and natural resources university, mollasani in northeast of ahwaz, using a randomized complete block design of a factorial layout with 4 replications. main factors were planting ...

In order to evaluate the yield, yield components and protein contents of two wheat cultivars (Zarrin and Gaspard) in sole cropping and intercropping systems,an experiment was conducted using replacement serious technique and different combinations of intercropping with high plant density and optimal of each cultivar. A factorial experiment was conducted in the form of randomized complete block ...

abstract field experiment was carried out at the ferdowsi university research field, mashhad, iran during 2006-2007, to determine how much effective the n-fertilization is, to find out the most suitable plant density which could be used in chamomile (matricaria chamomilla l. asteraceae) to increase the yield of anthodium flowers and content of essential oil. the experimental design was as two f...

in order to evaluate intercropping of summer savory (satureja hortensis l.) and persian clover (trifolium resupinatum l.), an experiment was conducted at agricultural research station of ferdowsi university of mashhad in 2004 growing season. treatments were sole cropping of persian clover (eight rows), double-row intercropping of persian clover and summer savory with 27, 40 and 80 plants.m-2 (e...

for assessment and comparison of measuring density methods of festuca ovina, bromus tomentellus and prangos ferulacea, three plants communities are selected. in all of plant community, reference area was defined and samples 7000 (70*100) square meter was selected. whole the area, sampling was accumplished as systematic-random. in each area, 5 transect 100 meter are established. then in areas 70...

abstract improving nitrogen use efficiency (nue) is an important objective of the agroecosystem management. a field experiment was conducted to study the effect of different competition patterns on nitrogen balance in the wheat agroecosystem. experimental design was split–plot based on randomized complete blocks with four replications. the main plots consisted of different nitrogen rates (i.e. ...

abstract in order to study the effect of planting season (autumn and spring) and plant density on growth traits and flower yield (dry weight of flower) of matricaria (matricaria chamomilla), an experiment was carried out at the research field of agricultural faculty of shirvan, affiliated to ferdowsi university of mashhad. a split plot design with two factors, including planting time and plant ...
