Comparative advantage is one of the most important economic criteria in production, import AND export programming. In this survey, two group of comparative advantage recognition indices is used to investigate existence of the cereals production comparative advantage in JIROFT & KAHNOOJ in 2006-2007. The SCB, DRC AND NSP are the first indexes AND EAI, SAI AND AAI are the second. Based on the findings, none of the cereals had the comparative advantage. Corn comparative advantage in the region was more than the country average. The calculated protective coefficients AND PAM matrix showed that producers are paid indirect subsidies in form of output AND inputs AND also gain more profit by government intervention comparing to free trade.

Temperature AND humidity are two important parameters affecting the quality AND quantity of greenhouse products so two double greenhouses were manufactured in 3.5, 40 AND 11 m in height, length AND width respectively in agricultural research center of JIROFT AND KAHNOOJ to study these effects. Both of greenhouses are similar in materials, final height, gutter height, covering AND field operation but in one of them one heating system, two ventilation fans AND one wooden pad were assembled AND temperature AND humidity besides yield were registered in both of them. The results showed that temperature changing trend inside AND outside of the unheated greenhouse were in same phase AND this isn't suitable in cold night so the greenhouse with heating system had more yield AND picking cucumber fruit numbers than another. Therefore it is necessary to be heated by artificial systems. Because of rapid relative humidity changing in outside of greenhouse in the end of the season, the efficiency of fan AND pads cooling system is so low then using of evaporating cooling systems such as fans AND pad wasn't proposed AND recommend to optimize the temperature by ventilation AND shading the greenhouse AND in hot days production will be cut.

  Biovar 2/ race 3 of Ralstonia solanacearum is the causal agent of bacterial wilt of potato in Iran. Root, tuber AND stem samples of potato, other crop AND weeds collected from JIROFT AND KAHNOOJ in Southern Kerman province during 1997-1999, were cultured on TZCA Kelman's medium for isolation of R. solanacearum. In addition pathogenicity of the isolated strains was tested on some crop plants AND weeds under greenhouse conditions. Results showed where aspotato is the only cultivated species infectednaturaly in the area, strains of R. solanacearum (biotype 2- A/race 3) were also isolated from stems AND roots of Chnopodiumalbum, Malva sp., Vicia sp. AND Acroptilon repens. Wilt symptoms were induced following stem inoculation on potato, tomato, eggplant, Physalis alkakengi, Datura stramonium, Solanum nigrum AND Vicia sp. Under greenhous conditions AND the bacterium was reisolated from symptomatic plants.Melilotus officinalis, Cardaria draba, Portulaca oleracea, Phaseolus vulgaris, Amaranthus sp. AND Rumex sp. showed no symptomps in greenhous inoculation trials but the bacterium was reisolated from the stem segments, 5 centimeters above the inoculation sites, one to two weeks after inoculation.

In order to study the possibility of changing corn planting pattern by using narrower rows AND eliminating some furrows, an experiment was conducted in the fields of Agriculture Training Center of Shahid Dehghanpur of JIROFT, Iran in 2001 on the basis of a RANDomized Complete Block Design with three replications. The studied was composed of 18 treatments including inter-row spacing of 35 cm with the densities of 75000, 85000 AND 95000 plants. ha-1 (T1, T2 AND T3, respectively), inter-row spacing of 35 cm with the elimination of four unplanted furrows with the densities of 75000, 85000 AND 95000 plants.ha-1 (T4, T5 AND T6, respectively), inter-row spacing of 75 cm with the densities of 75000, 85000 AND 95000 plants. ha-1 (T7, T8 AND T9, respectively), inter-row spacing of 75 cm with the elimination of one planting row with the density of 75000, the elimination of two unplanted rows with the density of 85000 AND the elimination of two unplanted rows with the density of 95000 plants. ha-1 (T10, T11 AND T12, respectively), inter-row spacing of 55 cm with the densities of 75000, 85000 AND 95000 plants. ha-1 (T13, T14 AND T15, respectively) AND inter-row spacing of 55 cm with three unplanted rows AND the densities of 75000, 85000 AND 95000 plants. ha-1 (T16, T17 AND T18, respectively). Measured traits included grain yield, row number per ear, grain number per row, 1000-grain weight, grain ratio to total, plant height, biomass, mean ear weight AND harvest index. Results showed that the effect of treatments was significant on grain yield, 1000-grain weight, plant height AND biomass at 5% statistical level AND on grain number per row, ear length AND mean ear weight at 1% probability level. But, their effect was not significant on other traits. The highest grain yields were obtained from treatments T1, T12, T5, T7, T4 AND T14 which resulted in the production of 17.51, 16.81, 15.99, 15.66, 15.26 AND 15.25 t grains per hectare, respectively. Finally, treatments T12, T4 AND T5 can be recommended for studied region given the results of all measurements AND the decrease in applied water level (lower area of lAND was irrigated).

Purple nutsedge causes severe damages to vegetable crops in JIROFT, KAHNOOJ AND BirjAND. In order to evaluate the effects of high temperature AND time of exposure to high temperatures on various ecotypes of purple nutsedge tubers, a factorial experiment was conducted based on rANDomized complete block design with 3 replications in the Research greenhouse of BirjAND University, Iran, in 2016. Experimental factors consisted of 3 ecotypes (JIROFT, KAHNOOJ AND BirjAND), different temperatures from 40 to 60°C with 5°C increments, AND exposure time including 1, 2, 4, 8, 16, 32 AND 64 hours. Results indicated that at all exposure times, 40°C temperature did not affect the growth characteristics of purple nutsedge, while at 45 °C, increasing the exposure time decreased the growth characteristics of purple nutsedge. Three-parameter logistic model estimation showed that  tuber viability (T50) at 45 °C in JIROFT ecotype was 14.64 hours, it decreased to 5.01 hours  at 50 °C. T50 was about 66% lower than for 45 ° C, but it was 19.76 hours in KAHNOOJ ecotype at 45 °C, while at 50 °C, this parameter decreased to 2.73 hours (86.2%). T50 of BirjAND ecotype at 45 °C was 12.90 hours, but at 50 °C, the tubers viability reduced AND T50 was 8.91 hours (31% decrease). Results of this research could have an important role in controlling purple nutsedge in vegetable fields.

Upgrading of Ilmenite AND Titanomagnetite concentrates of KAHNOOJ ore by Slag-making route was investigated. The effects of the process parameters AND pre-oxidation of the starting materials on the formation of slag, separation of slag from pig iron AND distribution of elements have been studied. The results revealed that the time AND temperature of reducing AND melting steps, along with the type AND amount of flux are the most important parameters of the process AND have a significant effect on the characteristics of the products. For instance in the presence of 5 wt% of dolumite, the quantity of vanadium oxide in slag decreased on increasing the time AND temperature of melting steps. The results also indicate that the pre-oxidation of the concentrates has no considerable effect on the process.

During one year, the Bardsir earthquake (2010/07/31, MS=5. 8), the KAHNOOJ earthquake (2011/06/15, MS=5. 7) AND the Sirch earthquake (2011/06/26, MS=5. 2) have occurred in Kerman province (one of seismologically active area in eastern Iran). The earthquakes have been relocated AND processed using local AND regional recorded seismograms. Mechanism of the earthquakes were calculated using the first P motion method. Processing both locations AND focal mechanisms indicate that these earthquakes are probably related to the Lalehzar, Sabzevaran AND Golbaf fault systems, respectively. Bardsir AND Sirch earthquake faults dip northeastward AND KAHNOOJ earthquake fault dips eastward, indicating that both source faults dip steeply. Mechanisms of the earthquakes were right lateral strike slip, reverse with right lateral strike slip component AND reverse mechanism, respectively. Finally, this research is in accordance to the field investigations, in which the maximum intensity in MM AND JMA scales was estimated ~VI near epicentral area AND no co-seismic surface rupture were detected for these earthquakes.
