Basrah Journal For Date Palm Research, Volume 8, Issue 2, Pages 1-10

This study was conducted in tissue culture Lab. In Date palm research center –Basrah university to study the effect of irrigated and spray with NPK fertilizer with concentrations (0.25, 0.5, 0.75 and 1) gmL. in addition to control treatment in plantlet acclimatization of date palm cv.Ashkar in vitro
The results as follow:
1. The percentage of acclimatized plantlet: the irrigated and spray with (0.75) gmL. led to give a higher percentage of plantlet acclimatization with significant difference of other used concentrations except spray with (0.5) gmL. concentration which the percentage of acclimatized plantlet in irrigated operation was (90%) and spray operation was (100%) while the lowest percentage appeared in control treatment with significant difference of other used concentrations except irrigated with (0.25) gmL.
2. Number of new leaves formatted: results showed the irrigated and spray with (0.75) gmL. concentration led to gave a high average of new leaves formatted which (2) leaveplantlet by irrigated operation and (3) leaveplantlet by spray operation while no any new leave formatted in treated by irrigated with (0.25) gmL. and control treatment irrigated and spray operations.
3. the leave length: results showed the irrigated and spray by (0.75) gmL. led to gave a higher average of leave length which (24.5) cm in irrigated operation and (27.16) cm in spray operation with significant difference of other used treatments and a lowest average of leave length was in control treatment which (17. 5) cm in irrigated operation and (17.25) cm in spray operation with significant difference of other treatment except irrigated with (0.25) gmL.
4. Number of formatted roots: the irrigated and spray with (0.75) gmL. concentration led to gave a higher average of formatted roots which (6.47) and (7.84) respectively with significant difference of other treatments while the lowest average appeared in control treatment with significant difference of other treatment except irrigated with (0.25) gmL.
5. Roots length: the treated by irrigated with (0.75) and (1) gmL. gave a higher average of roots length which (5.92 and 5.56) cm respectively while the spray by (0.75) gmL. superior significantly on other treatments which (7.76) while lowest average of roots length appeared in control treatment in irrigated which (3.25) and in same treatment in spray operation which (4.64) cm but without significant difference of spray with (0.25) gmL. it which (4.85) cm.
6. Chlorophyll: the results showed the irrigated and spray with (0.75) and (0.5) gmL. led to gave a significant increased in chlorophyll A, B and total chlorophyll while other treatments do not difference about them except the spray with (0.25) gmL. concentration do not difference significantly of spray with (1) gmL. and control treatment in it effect of chlorophyll A

This study was under taken in date palm research center –Basra Univ. to effect of planting date and plan growth regulators in the different concentration .the offshoots was dipped in the different concentration from plan growth regulators(IBA and IAA) for ten minuets during tow planting dates (spring and autumn) the results of study were :
1-This study show the dipping treatment of offshoots in the ten minuets by 500 ppm(IBA and IAA) led to have higher ratio of offshoots success in both cultivars were reached (65.41 and 56.66)% respectively.then have higher ratio in autumn planting date in both cultivars were reached(56.72 and46.63)% respectively with comparison with other planting date.
2-its showed signifecant effects between planting date and plant growth regulators then use500 ppm(IBA and IAA) in autumn led to have higher ratio of offshoots success in both cultivars were reached (84.16,63.33)% respectively.
3- use the same treatment in part (1,2) led to formation the high nember and length of roots after sex months of planting in both cultivars.

This study was conducted to know the percentage of the infection and economical loss cused by Batrachedra amydraula M. (Cosmopterygidae: Lepidoptera)on the date palm (Phoenix dactylifera L.) in Abu-alkhaseb region in Basrah governarate in 2009 season.
The study show that the Batrachedra amydraula start infection to date palm at the beginning stage of Jamry and the percentage of infection which was 13.95% in the 1st week of May and increased to which was its highest rate ate the end of May and the begeing of June which reached 52.00% then decreased at end June and July.
Also the Results showed that the number of the fruits 4902 fruits/tree in the 3rd week of April, it become 3405.6 fruits/tree in the 2nd week of July as aresult of fall number of fruits it which was to 1496.4 fruits/tree (17.20 kg) , included 590.2 fruits/tree (6.78 kg) , for this season the ratio of economical loss cused by Batrachedra amydraula is 17.33% .

Comparsim effects of acariside(Albarq 42.8%EC) and pesticide (Mig 5%EC) on scale Insect Partatoria blanchardi Targ (Homoptera: Diaspididae) and date dust mite Oligonychus afrasaiticus (Acari:Tetranychidae) on date palm(Phoenix dactylifera L.).

The study was done to assessing efficiency two pesticides Albarq 42.8%EC and Mig 5%EC on white Scales insect Partatoria blanchardi Targ (Homoptera: Diaspididae) and date dust mite Oligonychus afrasaiticus (Acari:Tetranychidae) obn date palm Hilawii C.V.
The results showed superiority the Albarq 42.8%EC acaricide and Mig 5%EC insecticide in mortility ratio to white Scales insect when it reached to (80.68%, 44.67%) respectively.
The study was showed significant difference in mortility ratio for different concentrate , the concentrate 0.75% of tow pesticides give high ratio was (84.47%,53.28%) respectively.
The results showed superiority Albarq 42.8%EC acaricide to reducing the numbers date dust mite from 31 to 0 per 10 fruits after 14 days from treatment , comparsion with Mig 5%EC insecticide which reducing the numbers of mite from 24 to 9 per 10 fruits after 14 days from treatment.

The following fungi Alternaria alternate, Aspergillus niger, Aspergillus terreus, Rhizopus sp. were isolated from the nymphal and adult insters of the Dubas Date plam insect. Ommatissus binotatus var. lybicus De Berg. Fungal inoculums of 106 spores/mel revealed a rate of mortality (42, 38.1, 35.9, 35.9 and 35.5)% respectively on the nymphal for both Trichoderma harzianum, T.viride, Beauveria bassiana, A.alternata, Rhizopus sp. The spore suspension of T.harzianum and T.viride on nymphal instarse showed rate of mortality (68.5, 65.8)% respectively after 72 hourse.
The effect of culture of T.viride, T.harzianum, Rhizopus sp. on namphal instars mortality was (51.2, 50.6 and 49.6)% respectively. The effect of plant extracts for Clerodendron inerme, Nerium oleander on nymphal instars mortality was (62.6, 60.4)% respectively after 72 hourse. Its found that concentration 1.5% was mortalities 68.5% after 10 Days of treatment.
It field the spore suspension T.viride on nymphal and adult insters of the insect revealed 64.2% after 10 days treatment. While under field conditions spore suspension caused the highest mortality 63.1% when used date syrup compared with residue treatment. It field the plant extracts of Clerodendron inerme on nymphal and adult insters revealed 49.3% after 10 days of treatment. While the plant extracts caused the highest mortality 47.9% when used date syrup compared with residue treatment.
