ABSTRACT

The objective of this study was to use some indices related to soil aggregate instead of soil erodibility factor KUSLE of the universal soil loss equation ( USLE ) for a selected calcareous soils. Twelve composite calcareous soil samples from 0 - 15 cm depth were collected from 12 different locations at Nineveh provenance. The selected soils were analyzed for five commonly used erodibility indices used for identify soil erodibility .These indices are ; Clay Aggregation Index (CAI ) , Clay Dispersion Ratio (CDR) , Clay Flocculation Index( CFI ), Dispersion ratio ( DR ), and Erosion Index of Bouyoucos ( EIB)
The results indicated that there is a highly significant positive correlation ( r = 0.891**) between EIB and KUSLE in comparison to the other criteria which pointed a weak correlation Also ,the results show through variance analysis that the mean of the criterion EIB values ( 3.651 ) was very close to the mean of the KUSLE values ( 3.839 ). These results mean that EIB is more reliable index for prediction the soil erodibility in calcareous soils.

The adsorption experiment of three different calcareous soils (loam and clay) for Nineveh governorate (Tel Aakoub, Ibrahim Al-Khalil, and Taqlif) was classified under Aridsol-Calciorthids with a slight slant to alkaline (7.43), non saline (3.24 dS m-1), Low content of organic matter (17.3 gkg-1), cation exchange capacity (42 Cmolc kg-1), high content of carbonate minerals (409 g kg-1). Lead adsorption was studied by batch equilibrium method at a temperature of (298 Kelvin) for lead solutions (5,10,20,40,80,100 mg L-1). For 48 hours,the lead was measured in equilibrium solutions and the adsorption criteria were calculated according to Langmuir ,Freundlich and the DR equations. The results of the mathematical description of lead adsorption showed high efficiency in the use of Langmuir , Freundlich and the DR equations at the concentrations used. The lead added to the soil was also distributed between the equilibrium solution and the solid soil phase in terms of propagation coefficient values (Kd), which ranged from (111.8) to(255.5 l kg-1)with an average of 169 l kg-1. The DR equation exceeded the Langmuir and Freundlich equivalents in the description of lead adsorption to obtain the highest coefficient of determination (R2) and a lesser standard error (SE).The adsorption capacity (qm) of the lead ion in the study of soil was( 13.63 - 41.48 mol g-1).The K value associated with the adsorption capacity ranged from (-0.44) to (- 1.24) (mol2 KJ -2). The value of (E) is the free energy rate of the reaction ranged from the lead adsorption values (0.63 - 1.06 KJmol-1)

The results of food kind exposed to radiation exhibited a different mean mortality on adults reached 52.41 ,58.70 ,50.37 and 52.41% and for percent egg hatch reached 12.96 ,17.78 ,18.33 and 18.33% while the mean mortality in larvae reached 45.56 ,46.48 ,41.30 and 38.15%, and the percentage of pupae transformation to adults reached 47.96 , 46.80 , 45 ,43.52%.Results were positively proportion with increasing the energy levels reached 22.08 , 64.86 , 65.14% for larvae , while the mean percentage of eggs hatchling and the means percentages of pupae transformation to adults decrease with increasing energy levels reached 23.61 , 17.66 and 10.28% for egg hatching , and 58.61 , 40.31 and 29.17% for pupae transformation .The means of adults and larvae mortality increase with increasing the exposure period to radiation reached 31.39 , 58.06 , 72.78 , 75.83 and 76.94% , and 21.67 ,41.39 ,54.72 ,64.44 and 74.17% respectively. Means of eggs hatching percentage and pupae transferred to adults were proportionally decrease with increasing the exposure period. Also the storage of bags affected on mortality of adults Khapra beetle , which reached in bags 5.83%. Compared without bags reached zero, and the mean percentage of eggs hatching in bags treatment decrease reached 31.67% compared without bags reached 100%. While it was no differences in the larvae mortalities of both treatments . Also the pupae transferred to adults were proportionally decrease in bags treatment reached 89.17% compared in controlling without bags reached 100%.

The experiment was carried out at the farm at Filed crops Department , College of Agricultural engineering sciences , Duhok University in season 2018-2019 to construed selection index for five faba bean genotypes under different levels of phosphorus fertilizer .The results exhibited that all selection indices include the grain yield gave relatively efficiency , the best selection index were grain yield, number of pods plant-1 and number of seeds pods-1 , so that we can using these characters as criteria’s of selection of faba bean genotypes . Also the results showed that the highest mean selection index was 216.26 for latti kia genotype and significant and difference over all other genotypes .
The heritability broad sense was high for all studied characters and ranged between 0.94 to 0.99 . Regarding to the genetic advance as mean gave high values for first pod height (57.10) , grain yield plant-1 (43.97) , number of main branches plant-1 (33.92) and number of pods plant-1 (31.52) and medium for plant height , days to 75 flowering , number of nodules plant-1 and number of seeds pod-1 . So that we can using these desirable characters to improve the faba bean genotypes .
