the impact of reduction in growth season of autumn crops on sustainable use of groundwater resources
currently, a considerable amount of water usage in various sectors of the khorasan razavi province: agriculture and industry etc., is supplied through the restricted underground water resources. however, the current trend of water usage in the various sectors, including agriculture, is a cause for serious concerns regarding the durability of quantity and quality of available water to meet futur...
In the classical data envelopment analysis (DEA) models, inputs and outputs are assumed as known variables, and these models cannot deal with unknown amounts of variables directly. In recent years, there are few researches on handling missing data. This paper suggests a new interval based approach to apply missing data, which is the modified version of Kousmanen (2009) approach. First, the prop...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
in order to examine the allelochemic effects of seed and leaf aqueous extracts of eucalyptus (eucalyptus globules labill.) on germination, growth, morphological and biochemical criteria of barley (hordeum vulgare l.) and flixweed (descurainia sophia l.), a series of experiments with five levels of seed and leaf aqueous extract of eucalyptus, including concentrations of 30, 50, 70, 90 and 100 pe...
Black walnut (Jug/am nigra L.) seeds are large and require stratification for germination. However, many seeds fail to germinate following stratification. Radiography can be used to select empty seeds, but cannot determine which full seeds will germinate. The objective of this study was to determine if any discrimination could bc achieved through use of nuclear magnetic resonance (NMR) spectros...
In spite of the development of various improved cultivars of maize, yield in Nigeria has continued to be hampered by the over cropped nature of most farmlands as well as a wide range of pests and diseases. This study therefore carried out an analysis of agro-chemical inputs’ use in maize production among small scale farmers in Iwo Local Government Area of Osun State. Specifically, the study inv...
Seed coat color as a perfect and simple index is effective in water absorption, seed dormancy and germination. The mustard plant produces seeds with different coat color. So, in order to investigate the effect of seed coat color on germination rate, the percentage of germination and dormancy of Mustard (Sinapis arvensis L.) seeds an experiment was carried out based on a completely randomized de...
on- the-job training on of the most effective tools for managers to cope with the changing organizational environment. it grantess suitable services to customers, particularly in public service enterprises. if such training os goal oriented, planned systematically, and tailored to the employees, job content, then not only it could increase employees and organizational performance, but also it c...
Seeds that contain large amounts of oil, starch, fibers and phenols are the most difficult tissues for RNA extraction. Currently, there are some reports of virus detection in seeds using commercial kits for RNA extraction. However, individual seeds were used, which may not be always suitable for analyses that deal with large amounts of seeds. Sangha [1] described a simple, quick and efficient p...
Safflower (Carthamus tinctorius L.) is an only oilseed crop which, is native to Iran where, is known as its diversity center. The genetic variation study provides valuable information about maintenance and their usage of germplasm for breeders to increase efficiency of breeding programs. In the current study, sixty-four genotypes were assessed for 20 agronomic nag morphological traits for genet...
