Prediction equations based on 130 sample trees from thinned and unthinned loblolly pine (Pinus taeda L.) plantations in central Louisiana re presented for the green and dry weights of aboveground tree components. Sample trees ranged from 2 to 21 in. dbh, 18 to 94 ft in height and from 9 to 55 yr in age. Significant differences in partial stem weight between trees from thinned and unthinned stan...
This research was conducted at the research field of West-Azerbaijan (Saatloo station, 45° 10′ 53˝ E/ 37° 44′ 18˝ N and 1338 m above sea level), located 25 km from Urmia city (Iran) during 2019-2020 cropping seasons, as a factorial layout based on randomized complete block design with three replications. The first factor was irrigation regime at three levels (supplying 100, 75 and 50% of net ir...
Background and objectives: The application of growth-facilitator materials to improve germination, early establishment, and plants growth can increase the success of rangeland improvement, planting, and pasture construction projects. In addition, growth facilitators can improve the quantity and quality of vegetation cover and production in dry-farming lands by increasing the success of cultivat...

The first factor included sensitive wheat cv. (Tajan) and tolerant cv. (B...
The water vapour column density or vertically integrated (IWV) ranges from about 8 mm in winter to 25 summer Bern, Switzerland. However, there can be day episodes when IWV drops 2 even less so that the atmosphere is extremely dry. We selected an event February 2021 tropospheric radiometer TROWARA measured a mean value of 1.5 ± 0.2 for time interval one Bern. ECMWF reanalysis ERA5 indicated slig...
