knowledge of environmental and ecological factors as well as growth and development pattern of fruit trees is an important task in orchard management and fruit industry. in addition, determination of growth pattern is an important aspect in the orchard management system. in this research, the total photosynthesis rate and growth pattern was measured in nine asian pear cultivars. experiment was ...
drought affects on all aspects of human actirities seriously as a climatic phenomenon. however, the studies related to this phenomenon based on suitable method are very few. studying the drought features and its prediction can be effective on decreasing of resulted losses or damages. therefore, drought and evaluation of its prediction possibility are studied for some stations of ardabil provinc...
introduction the movement and fate of solutes in the subsurface in affected by a large number of physical, chemical processes requiring a broad array of mathematical and physical sciences to study and describe solute transport. the dispersion is an important parameter in the advection – dispersion equation, which is used in assessing, and solving the problems related to the contamination and th...
the moe and mor are controlled by production variables of particleboard process. now, the basic question is which of the particleboard variables is effective on bending strength property? 13 variables of internal scientific resources were measured with 100 repeats. the study steps include the following; liner regression or stepwise, genetic algorithm, and artificial neural network. the number o...
evaluation of river discharges trends is very important for water resources management and design of irrigation and drainage networks. in this research, annual, seasonal and monthly trends of maroon river discharge were evaluated using the mann-kendall and senâs slope estimator non-parametric tests and the regression analysis parametric test. for this purpose, river discharge data from five h...
due to the use of secale montanum for different rangelands reclamation across the country, management of these ecosystems need to be aware of its ability to environmental stresses. this research investigated the effect of pollutant element of cu and pb on seed germination and growth of this species in laboratory. therefore, the effect of five treatments (control, 50, 100, 150, 200ppm) of pb (no...
in order to determine the best traits related to indirect increasing of grain yield, five wheat genotypes (zagros, tajan, durum cul., kohdasht and n-81-18 line) were evaluated by using randomized complete block design (rcbd) with 4 replications in research field of gorgan university of agricultural sciences and natural recourses. the studied traits included leaf area index (lai), crop growth ra...
