To estimate genetic parameters of yield and yield component of chickpea, six chickpea genotypes were crossed in complete diallel crossing scheme in glass houses of Seed and Plant Improvement Institute in 2007. Parents, direct and reciprocal crosses (36 entries) were evaluated using randomized complete block design with four replications at Grizeh station, Sanandaj, Iran in spring of 2017 growin...
The major problems in transplanting the landscape trees are high level of mortality and low establishment rate of transplanted trees, especially in the first year. In order to achieve the best condition for successful transplanting of pine and plane trees in Isfahan landscape, the present study was carried out based on a completely randomized block design with four replicates and three treatmen...
"Technical Report" The quality of coastal water resources at the downstream of watersheds is decreasing mainly due to different anthropogenic activities. In this research, temporal variations of groundwater quality were investigated in a 25000 ha coastal area in Mazandaran province. Groundwater samples were taken from 37 observation wells in the region before (winter 2009), during (spring ...
Impact of revised and potential future albedo estimates on CCSM3 simulations of growing-season surface temperature fields for North America" (2010). USDA Forest Service / UNL Faculty Publications. Paper 144. Abstract Recently published albedo research has resulted in improved growing-season albedo estimates for forest and grassland vegetation. The impact of these improved estimates on the abili...
Appropriate use of rangelands, creates vegetation stability, prevents degradation and improves their suitability conditio. Determination of allowable level of vegetation utilization of the species could lead to plan for the proper distribution of livestock on rangeland. To measure the level of use, a 0.5 ha exclosure was established in Karsanak site before the start of the growing season in 20...
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...
Crop extent and frequency maps are an important input to inform the debate around land value and competitive land uses, in particular between cropping and mining in the case of Queensland, Australia. Such spatial datasets are useful for supporting decisions on natural resource management, planning and policy. For the major broadacre cropping regions of Queensland, Australia, the complete Landsa...
Seasonal variation (e.g. temperature and photoperiod) between growing seasons might affectinulin content and inulin yield of Jerusalem artichoke. However, there is limited information ongenotypic response to seasons for inulin content and inulin yield. The objective of this studywas to investigate the variability in genotypic response to seasons for inulin content and inulinyield of Jerusalem a...
water logging stress is one of the most important factors which affect wheat production particularly in western regions of golestan province. this experiment was carried out in order to evaluate of six genotypes (n-81-18, arta, moghan, n-80-19, urwyt-82-11 and urwyt-82-17) of bread wheat in water logging condition at 2006-2007 growing season in gorgan agricultural research station. the experime...
Semi-arid ecosystems with annual moisture inputs dominated by snowmelt cover much of the western United States, and a better understanding of their seasonal drivers of soil respiration is needed to predict consequences of climatic change on soil CO2 efflux. We assessed the relative importance of temperature, moisture, and plant phenology on soil respiration during seasonal shifts between cold, ...
