Growth Analysis of Spanish Faba bean (var. Alfa dolce) under effect of ploughing methods

The research was carried out during 2009-2010 in agricultural seasons, in Alqusser area, western south of Homs city to study growth analysis of Spanish faba bean (var.alfa docle) under the effect of different ploughing methods on leaf weight ratio (LWR) relative leaf growth rate (RLGR), leaf area ratio (LAR), leaf area duration (LAD), crop growth rate (GGR) and net assimilation rate (NAR), using four ploughing methods: surface tillage(T1), disk tillage (T2), place tillage (T3) and disk-turning (T4).the experiment was designed at randomized complete blocks, with five replications. The study showed the following: The ploughing methods of disk Tillage (T2), Place tillage (T4), and disk- Surface Tillage (T1) had a Significant increase in leaf weight Ratio (LWR), Relative leaf growth Rate (RLGR), leaf Area Ratio (LAR, leaf Area Duration (LAD), Crop Growth Rate (GGR) and Net Assimilation Rate (NAR) during the Tow seasons. Disk-turning (T4) had significant increase over disk-tillage (T2), and place tillage (T3) in all physiological indicators mentioned above (LWR, RLGR, LAR, LAD, GGR, and NAR). On another hand, there was no significant increase between ploughing methods disk-tillage and place tillage in all studies indicators.

" Effect of boron and zinc foliar fertilization on the yield and its components of faba bean (Vicia faba L).

the experiment was conducted under Syrian coastal conditions to investigate (Vicia fabaL.), the effect of boron and zinc foliar fertilization on faba bean,either individually or in combination, by increased rates (0, 0.25, 0.50, 0.75, and 1 kg boron / has boric acid, and zinc at a rate of 0, 0.375, 0.750, 1.125, and 1.5 kg / ha as zinc sulfate). where fababeans were plantedin plastic pots(15L) in )2013/11/10(and )2014/11/10(.The soil in pots has high content of calcium carbonate, low boron and zinc content, with pH slightly basic (representative of the region's soils). Half boron and zinc fertilizer rates were sprayed after 33 days of germination and the other half ,after 65 days of germination. The results showed significant responses in all studied parameters (number of branches,number of pods / plant, weight of 100 seeds, and seed yield (Kg. / ha) on faba bean plant, as a result of foliar fertilization by boron and zinc. Fababeans response to boron is higher than to zinc fertilization in all studied indicators. However,the treatmentB75Zn75(0.75 kg boric acid and 1.125kg of zinc sulfate) is the best, as compared to others. Also, the driedseeds yield was increased by about 17.66%.

Identification of some species of aphids deployed in bean fields and citrus orchards in Latakia and the possibility of its transfer of local isolate of Cucumber mosaic virus

The research aims to Identify some species of aphids on plant families, and test the possibility of transfer to the local isolate of Cucumber mosaic virus. Two species of aphids in bean fields and citrus orchards have been defined, namely: Black bean aphid Aphis fabae and Cotton aphid Aphis gossypii, respectively, depending on the specialized classification keys. The infection proved vital feedback and testing the function using plants: Nicotiana tabacum and Chenopodium quinoa transfer each of the A. fabae and A. gossypii local isolate of Cucumber mosaic virus.

Assessment Of Some Vicia faba Bean Genotypes Under The Coastal Region

An assessment of nine vicia faba genotypes (flip84-59fb, AGUADOLCE LB 1266 SML, FLIP84-14FB, GIZE.461, REINA BLANCA, autochthon, Spanish, and Cypriotes) was achieved, during 2010-2011 and 2011-2012 seasons, in Al_Bassa farm, near Lattakia city. Superior genotypes will be adopted as a high yield improved varieties in that area, however, the other genotypes (possessing genetic characteristics, superior of local genotypes), will be used in future breeding programs. The results indicated a significant differences between studied characteristics of the genotypes, as Spanish genotype recorded the best pod length (17.16cm), having high degree of inheritance (68.24), followed by filp84-59fb genotype (15.1 cm), with weight seeds per pod (33.6 g), having high degree of inheritance (68.45), followed by the Cypriot genotype, by seed weight (14.66 g), number of pod (4.6), having low degree of inheritance (23.53), followed by Cyprian autochtone genotype, and Aguadolce.lb1266,and filip84 - 14fb number of pod (3.6). The Cypriot genotype was the best, in terms of pod weight (23:43 g), having high degree of inheritance (76.45) followed by Spanish (20.63g), and seed weight (3.93g), having medium degree of inheritance (54.82), followed by style filip84-59fb (3.73 g), and 100-seed weight (4.1g), having high degree of inheritance (97.49), followed by Aguadolce genotypes (285 g). The SML genotype is the best among premature genotypes in terms of flowering (46 days) and maturity (148 days), followed by Cypriot in terms of flowering (51 days) and flip84- 59fb in terms of maturity (155 days)

Variability, Correlation and Path Coefficient Analysis of Yield and Some Yield Components in Faba Bean (Vicia faba L.) Populations

In a study conducted at Research Center of Dara'a, General Commission for Scientific Agricultural Research during two growth seasons 2007/2008 and 2008/2009. 11 faba bean (Vicia faba L.) populations were planted in an experiment designed randomized complete blocks design with three replications. The objectives were investigation of phenotypic variance among populations studied, to determine the relationship among number of yielded branches plant -1, number of pods plant -1 , number of seeds pod -1, 10- green pod weight (g) and yield of green pods plant -1 (g) using correlation and path coefficient analysis. The combined analysis of variance showed highly significant differences among populations under study and for all characteristics studied, except number of yielded branches plant-1 where differences were only significant. The correlation and path analysis studies revealed that negative and highly significant relationship was found between number of yielded branches plant -1 and yield of green pods plant-1, while was positive and highly significant between yield of green pods plant-1 and 10-green pod weight. All direct effects of components studied were negative in both seasons, except 10-green pod weight, and these results suggested adopting the last component as a selection index during making selection of high yielding genotypes in faba bean populations. .

The effect of certain fungicides on mycoflora in the bean plant rhizosphere

This study was carried out to determine the effect of fungicides application (carbendazim, benomyl, thiram and tolclofos-methyl) on soil when used at the recommended rates and at duplicated rates on the fungi population in the bean plant rhizosphere. Results showed that tested fungicides caused significant reduction in the fungi population of rhizosphere bean plant when used at the both levels compared with control. The tested fungicides caused various inhibitory effects according to the application rate. However, the duplicated rate caused remarkable reduction in fungi population. This reduction continued 2 or 3 weeks when applied fungicides used at recommended or duplicated rates respectively.
