Abstract

The experiment was conducted in Ramadi city central Al-Anbar Gov. from 2012-2013, Include determine studied 7 mixtures of seeds and shadowing (0% and 50%) to study characteristics of lawn in addition of some vegetative growth . Factorial experiment (7×2) used within split randomized complete block design consisting 12 treatments in three replicated for each experimental unit (1m2). The results as follows number of lawn cut under saran shadowing in spring and summer season increasedcompared of without shadowing autumn and winter (3.7, 3.6, 2.9 and 0.3) (2, 3.1, 1.8 and 0.9) respectively increased lawn cut in spring wile lowest in autumn for mixture of seeds as 3.2 cuts to (T1, T2, T3, T4 and T6) and 3.7 cuts to (T1, T2, T3 and T4) respectively. Accumulative height value was 77.73 cm under saran shadowing and 60.8 cm without shadowing; Dichondra T7 gives lowest accumulative height was 26.77 cm. Under Saran shadowing density of plant was 104.39 plant/100cm2 while 59.57 plant/100cm2 without Saran and 85.46 plant/100cm2 to T2 , and 71.04 plant/100cm2 to T1 treatment. The degree of color was best under Saran at without shadowing in autumn was 7.29 and 5.86 degree and the mixture T4 gives best degree of color through four seasons (7, 7, 7.33 and 6.67) degree respectively. The degree of lawn type under Saran shadowing was best from without shadowing specially in spring and summer and mixture T4 was best from other mixtures and was 5.67 degree in autumn and 6.6 degree in winter and in spring and summer was 6.63 degree
