the purpose of this study was to investigate economic impacts (including production costs, mechanization growth, changes in productivity per area, changes in the size of the cultivated area and productivity of production inputs) and ecological impacts (including protecting the environment from degradation and soil erosion as well as sustainable use of chemical fertilizers) of rural agricultural...

Different drought indices often provide different diagnoses of drought severity, making it difficult to determine the best way to evaluate these different drought monitoring results. Additionally, the ability of a newly proposed drought index, the Process-based Accumulated Drought Index (PADI) has not yet been tested in United States. In this study, we quantified the severity of 2012 drought wh...

Drought represents one of the most relevant abiotic stress affecting growth and yield of crop plants. In order to improve the agricultural productivity within the limited water and land resources, it is mandatory to increase crop yields in presence of unfavorable environmental stresses. The use of biostimulants, often containing seaweed extracts, represents one of the options for farmers willin...

Based on the mathematical model of crop, an algorithm for quantitative assessment agricultural risk crops cultivated in specific soil and climatic conditions has been developed. Classification risks according to crop losses is proposed, similar gradation adopted insurance payments, but more detailed. It established that indicators do not depend level nutrition, each year are determined only by ...

Mixed intercropping of barley (Hordeum vulgare L.) with faba bean (Vicia faba L.) was compared with sole cropping for three growing seasons 2001–2003) at Holetta Agricultural Research Centre, in the central highlands of Ethiopia. The treatments were sole barley (125 kg ha−1), sole aba bean (200 kg ha−1) and an additive series of 12.5, 25, 37.5, 50 and 62.5% of the sole seed rate of faba bean mi...

Extended Abstract Introduction and Objective: Drought stress is one of the most important factors in reducing yield and barley production in rainfed arid regions, and counteracting or reducing the effect of stresses as a useful solution to increase barley yield. Therefore, improvement of stress-tolerant and suitable barley cultivars for arid and semi-arid regions is essential. Material and Me...

Justifiable usage of large-scale crop model simulations requires transparent, comprehensive and spatially extensive evaluations of their performance and associated accuracy. Simulated crop yields of a Pan-European implementation of the Environmental Policy Integrated Climate (EPIC) crop model were satisfactorily evaluated with reported regional yield data from EUROSTAT for four major crops, inc...

in order to locate the qtls involved in the inheritance of agronomical, physiological and metabolitical indicators of drought tolerance in barley, an experiment was carried out using a wheat-barley disomic addition lines. this research was conducted in 2003-2004 at the dry land agricultural research institute, sararood, kermanshah, iran. the results of analysis of variance revealed highly signi...

in order to map the genomic regions affecting barley drought tolerance indices, an experiment was conducted at the agricultural and natural resource station of sistan. seventy tow double haploid lines of barley with their parents (steptoe and morex) were examined using two 9×9 simple lattice (stress and non-stress), with two replications. each plot consisted of six rows that were 3m in length a...
