objective: citrus (citrus reticulata) is one of the most important horticultural plant in iran and weed management throuth ecological methods such as cover crop is a proper option in orchard management practices. methods: the experiment was designed as a split plot on the base of complete randomized block design with four replications in mazandaran province, sari, voushka county from 2010 to 20...

abstract. the purpose of this study was to investigate the effects of topographical factors on the classification of grassland plant communities in the rangelands of ghorkhud, northern khorasan province, iran. for sampling, land units were specified. a floristic list was prepared using minimal area method based on the nested plot (braun-blanquet method). 116 10m2 furrows were selected. within e...

this experiment was conducted to evaluate the effect of nursery establishment under plastic cover on yield of some rice cultivars at lordegan region in 2007. experimental design was a split plot with a randomized complete block with three replications. four rice cultivars (hashemi, hasani, saleh and native) were seeded at three seedling date (14 april, 5 may and 15 may). two first planting date...

Waste storage facilities must be protected against weathering once mining operations come to end, in order ensure structural integrity and avoid environmental pollution. Cover systems consisting on earthen materials layers that are placed over the wastes a widely spread solution fulfil such requirement. This paper presents an experimental study of cover system intended protect waste facility ca...

the aim of this research was to study the relationships between presence of plant species and environmental factors in garizat rangelands of yazd province and providing their predictive habitat models. after delimitation of the study area, sampling was performed using randomized-systematic method. accordingly, vegetation data including presence and cover percentage were determined in each quadr...

Cover: A scatter plot of raw values of the first microarray hybridization comparing flower to leaf sample.

BACKGROUND A simulation model that relies on satellite observations of vegetation cover from the Landsat 7 sensor and from the Moderate Resolution Imaging Spectroradiometer (MODIS) was used to estimate net primary productivity (NPP) of forest stands at the Bartlett Experiment Forest (BEF) in the White Mountains of New Hampshire. RESULTS Net primary production (NPP) predicted from the NASA-CAS...
