Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various director indirect mechanisms. Thirtytwo strains were isolated from 15 soils sampled in central Iran, byusing and comparing three different methods. The screening of soil samples by means of soil pasteplate method combined with isolation on mannitol agar proved to be the best strategy in terms ofreliability and selectivity. These test isolates were biochemically characterized. These isolates werescreened in vitro and identified by using BIBI(Bioinformatics Bacterial Identification Tool). BIBI wasdesigned to automate DNA sequence analysis for bacterial identification in the different fields. BIBIrelies on the use of BLAST and CLUSTAL W programs applied to different subsets of sequencesextracted from GenBank. These sequences are filtered and stored in a new database, which is adaptedto bacterial identification. Manuscript profile

In order to evaluate the effects of chlorella on broiler performance and immune system, an experimentwas performed by using 80 ROSS 308 male broiler chicks. The experiment was accomplished incompletely randomized design including 5 treatments with 4 replication and 4 observations in eachreplicate. The basal diet was based on corn-soybean meal (control) and without any additives. Agraded level of chlorella (0.07, 0.14 and 0.21%) was added to basal diet to formulating diets 2, 3 and 4respectively. An extra diet (diet 5) was formulate by adding a commercial prebiotic to the basal diet.Results showed that feed conversion ratio significantly decreased by adding the chlorella andcommercial prebiotic to the basal diet at 42 d of age (p<0.05). chlorella treatment had numericalincrease in response to phitohemoglotenine-P at 35 d. Results of this study showed that chlorella couldimprove performance and may increase cell immune response. Manuscript profile

The accurate planning and management for sustainable agriculture results in appropriate behaviors ofindividuals towards sustainability through changes happened in individuals’ knowledge and attitudesof sustainability. A survey of natural resources and agricultural researchers (N = 85) was conducted inIranian Province of ILAM to explore their attitudes of sustainable agriculture and to identify factorsthat influence these attitudes. Results showed that the attitude of the majority (63.2%) of researcherstoward sustainable agriculture was moderate and negative. Also, there were significant differencesamong the researcher's attitudes towards sustainable agriculture on field of study and level ofeducation. Based on correlation coefficients, positive and significant relationships were found betweenresearchers’ work experience, the number of refereed papers published, the number of extensionpapers published, the number of papers presented at national and international conferences, thenumber of books published , and the number of translated books and attitude towards sustainableagriculture. In addition, multiple regression analysis showed that three variables including the numberof books published, the number of refereed papers published, and the number of books translatedaccount for explaining 36 percent of variances of the dependent variable (attitude towards sustainableagriculture).

For evaluation of Iranian onion morphotypes potentials and application of them in breedingprogrames, seeds of 23 Iranian onion morphotypeswere collected from East Azarbaijan (RedAzarshahrmorphotypes), Tehran (Red Rey morphotypes), Razavi Khorasan (Red Neyshaboormorphotypes) and Zanjan (Gholyghese morphotypes). These onion morphotypes were planted inRCBD design in four replications in Seed and Plant Improvement Institute fromearly April 2010.Results showed high variation in studing traits among morphotypes.Red Rey2, Azar Gokan2, RedRey4 and local Neyshaboor2 morphotypes had the highest yield and marketing traits, but hadnodifference among morphotypes at tissue firmness. All morphotypes had low bulb dry matter and werenot suitable for processing. Results of cluster analysis among morphotypesshowed that 23morphotypes were clustered at 3 groups. In each cluster morphological traits of morphotypes wasadjust with their collecting location. Manuscript profile

Investing in research and development spending (R&D) affects total factor productivity (TFP).Recently new theories of economic growth have emphasized the relationship between R&D and TFPand also identified a number of channels through which a country’s R&D affects TFP of its tradepartner. This study seeks to estimate the effect of agricultural R&D and education spending and someother factors on agricultural TFP in Iran during 1971 to 2011. Agricultural TFP is calculated usingKendrick Index and the model is estimated by OLS method using E-Views 7.0.All explaining variables in the model (right-hand variables) effect on agricultural productivity indifferent lags positively with 5% confidence. The best lag length is opted using Akaike information,Schwarz and Hannan-Quinn criterion. The results show that 1 percent increase in R&D spending inagriculture, education expenditure in agriculture, government investing in agriculture and rainfall willpromote agriculture TFP 0.13 percent by 5 lags, 0.10 percent by 2 lags, 0.14 percent by 1 lag and 0.17percent at the same time respectively. R&D spending in other sectors (except agriculture) and importof capital inputs in agriculture are contained in the model as research spill-over. The elasticity of thesetwo factors is estimated 0.09 by 5 lags and 0.04 by 2 lags Manuscript profile

Entrepreneurship courses had a tremendous potential to improve the knowledge and skills of thestudents in Agricultural Applied-Scientific Education Centers (AASECs) to make a business aftergraduating. This study was designed to analyze barriers of entrepreneurship education coursesdelivering in AASECs in Fars Province. The population of the study consisted of all 1018 students infour AASECs in Fars province (Shiraz, Jahrom, Aliabad Kamin & Marvdasht) in 2010-11 academicyear. A multi-stage stratified random sampling was applied to select 178 students as samples research.The instrument for collecting data was a questionnaire, which its validity was confirmed by a panel ofexperts. In addition, the Cronbach’s alpha coefficient was calculated (α= 0.89) that confirmed thereliability of the scale used in the study. The factor analysis results showed that, weakness insupportive and counseling services (19.50%), inadequate of applied education (17.89%), inadequate ofrecognizing of financial and management regulation (11.94%) and weakness in educational planning(11.67%) were the main obstacles in delivering of entrepreneurship education courses in AASECs inthe Fars province. These four factors could explain 61.1% variance of the obstacle variable. Manuscript profile
