abstract- maize production, which is ranked after wheat and barely in fars province, iran, needs a considerable amount of irrigation water that is not available in scarce water conditions in drought situations. therefore, proper planting method can improve irrigation water management. the objectives of the present study were to investigate the effects of two planting methods, on-bed and in furr...
soil salinity is a serious problem in south khouzestan province. this study was conducted in shawoor agricultural research station, north of the city of ahwaz, on silty-clay soil with 8 dsm-1 salinity during 2006 and 2007. a completely randomized block design arranged in split plots with three replications was used. the plots (planting methods) were: broadcasting + disk harrow (p1), broadcastin...
In order to evaluate the effects of planting methods and seeding rates on growth characteristics and yield of alfalfa (Medicago sativa L.), Hamedani cultivar, a field experiment was conducted in 2008 at College of Agriculture, Shiraz University, Iran. The experimental design was a completely randomized block with four replicates in a factorial arrangement of the treatments. The factors consiste...
A method for locating potential tree-planting sites in urban areas: A case study of Los Angeles, USA
A GIS-based method for locating potential tree-planting sites based on land cover data is introduced. Criteria were developed to identify locations that are spatially available for potential tree planting based on land cover, sufficient distance from impervious surfaces, a minimum amount of pervious surface, and no crown overlap with other trees. In an ArcGIS environment, a computer program was...
Optimum planting geometries have been shown to increase crop yields in maize-soybean intercrop systems. However, little is known about whether changes in planting geometry improve the seasonal water use of maize and soybean intercrops. We conducted two different field experiments in 2013 and 2014 to investigate the effects of changes in planting geometry on water use efficiency (WUE) and evapot...
eld to prepare for planting, while the tractor and crew on the right are planting trees. This method provides a weed-free soil immediately after planting for preemergence herbicide applications. W eeds reduce the value of nursery crops. They compete with crops for nutrients, light, and water. Some vine weeds climb nursery crops, requiring excessive labor for hand removal. Most serious are peren...
In order to determine the best method of planting for two varieties of watermelon in Varamin (Charleston Gray and Mahbube) through the three methods of planting (direct sowing of seeds, germinated seeds and transplanting of seedlings), a factorial experiment was conducted as a randomized complete block design with 4 replicates during two years (2007-2008) at the Agricultural Research Center, Va...
Balancing forest harvesting and restoration is critical for forest ecosystem management. In this study, we used LANDIS, a spatially explicit forest landscape model, to evaluate the effects of 21 alternative forest management initiatives which were drafted for forests in the upstream region of the Hun River in northeastern China. These management initiatives included a wide range of planting and...
In the present study, the effects of different levels of irrigation, organic mulch and planting method on the mungbean yield in Badjgah were investigated. The experimental plan in the first year was full randomized block, while in the second year, it was full randomized split-split plot block design, in three repetitions. The results showed that in the FI treatments, the yield was increased up ...
an experiment was conducted at ecbatan research station in hamedan in two years (1998-99) to study the effects of planting density and methods and also seed clove size on yield of hamedan garlic. the experiment was in factorial 3 x 3x 3 in randomized complete block design with three cultivation methods, three sizes of seeds and three plant densities in three replications. the data were analized...
