The experiment was carried out during growing season (2016-2017) at station of greenhouses, AL-Muthanna university- collage of agriculture- second research station (Al-Bander) to study the response of introduced tomato cultivars to different concentrations of potassium under protected agriculture conditions. The research included three cultivars (Pusa ruby - Arka vikash- Arka Alok) and three levels of Potassium Fertilizer (90-180-270 kg/ha-1). The Randomized Complete Block Design with factorial experiment (RCBD) with three replicates. The results showed the superiority of Arka Alok variety over others in plant height 121.76 cm, fruit width 6.82 cm, fruit length 4.23 cm, average fruit weight 130.61g, leaf area 129.5 cm2, the yield per plant 2.16 kg. The potassium level (270 Kg/ha-1) was also significantly higher in plant height 118.79 cm, fruit width 5.477 cm, fruit length 3.536 cm, 84.60 g, leaf area 127.3 cm2, TSS 4.97 and chlorophyll content 406.89 mg.m2 and yield per plant 2.16 kg. While the interaction showed significant difference (Arka Alok × 270 Kg.ha-1) in fruit length was 4.24 cm, chlorophyll content was 374.91 mg. m2 and the yield per plant was 2.82 kg. plant-1.-1.

The plots experiment is performed in College of Agriculture / University of Al-Qadissiya for the spring season 2013 ,the sandy loam soil is used to cultivate Tomato (Lycopersicon Esculentum mill) and Bean (Phaseolus Vulgaris L.) plants under salinity levels (without salinity , 6 , 8 and 10) dS.m-1 and compost levels (0,10 and 20)T.h-1 , their interactions completely randomized design (CRD) is used with six replicates, and the means of treatments are compared by L.S.D test 5% level .
The results are summarized as :
1- The enzyme activity are increased with increasing of the adding compost level 20Ton.h-1 and its interactions with salinity levels .
2- The enzymes activity are varied in rhizosphere development directions and the plants are differ in the site of highest activity , the enzyme activity in horizontal rhizosphere development direction is higher than the vertical direction .
3- The enzyme activity in bean rhizosphere is higher than in Tomato rhizosphere in activity except of the alkaline phosphatase at all rhizoshere vertical and horizontal directions .
4- The high inhibitor percentage of enzyme activity is at the level of 10 dS.m-1 salinity and the lowest is at the 6 dS.m-1 . The inhibition percentage are increased in vertical direction of rhizosphere developing (5-10)cm in tomato plant. The adding compost levels are varied by increasing or decreasing of enzyme activity according to rhizosphere development and it sites ..

A field experiment is conducted during the growing season of 2012 - 2013 on a sandy loam soil at Al-Berjsia researches station / Ministry of Agriculture , Basrah province , south of Iraq . The aim of study is to determine the effect of phosphate fertilizer starter solution on the growth of Two Tomato ( Lycopersicon Esculentum Mill ) varieties ( Hotuf and Speedy ) and P-uptake . Phosphate fertilizer as consternated super Phosphate (CSP) is applied at level 120 Kg P ha-1 . An equivalent of 0 , 0.05 , 0.10 and 0.20 % of Phosphor level are added as starter solution either at transplanting time or three days after transplanting . The remaining of Phosphorus level was applied to soil at two doses . Percentage of dead seedling , plant height , number of leaves plant-1 , number of branches plant-1 , number of flower clusters plant-1 , shoot and root dry weight , P concentration in leaves and P-uptake by plant are investigated . The results show that addition of CSP starter solution significantly decreases the percentage of dead seedling of compared with the control treatment . Plants received Phosphor starter solution show a higher growth parameters and P-uptake as compared with control treatment plants . Increasing the level of Phosphor starter solution from 0 to 0.20 % decreases percentage of dead seedling by 90.1 % and increased plant height by 19.23 % , number of leaves by 33 % , number of branches by 23.52 % , number of flower clusters by 69.24 % , shoot dry weight by 183.1 % , root dry weight by 175 % , P concentration by 60.8 % and P-uptake by 309.7 % . Comparing between two tomato varieties ,results show that Speedy tomato variety is more tolerant to transplanting and gives a higher growth and P-uptake , the results show also tomato seedlings received starter solutions at three days after transplanting time appear more resistant to soil shuck of transplanting than those plants received starter solution at transplanting.
