In apple orchards, 33 weed species belonging to 3 families were determined. The average density of weeds was.486 plant/m. From these, one of them belonged to Pterydophyta, species of Monocotyledoneae and species of Dicotyledoneae. Densities of these species were 3.76 plant/m for Agropyron repens,.73 for Chenopodium album,.03 for Bromus arvensis and 0.758 for Amaranthus retroflexus. According to the occurrence frequency of the weeds; C. album was found to be more than 56% in 6 subregion excluding Andırın, Pazarcık, Türkoğlu and Center. A. repens was found to be more than 50% in the 0 subregions. A. retroflexus was detected to be more than 54% in the other 7 subregions excluding Center, Türkoğlu and Pazarcık. Cynodon dactylon was found only in Afşin (50.%), Çağlayancerit (50.9%), Andırın (76.9%) and it was below 50% in the other 7 subregions. In terms of coverage, Alopecurus myosuroides, A. retroflexus, A.repens, B. arvensis, C. album, Convolvulus arvensis, C. dactylon and Lactuca serriola were determined to be within a range of 0. to 48.% in the study area while other species were below 0%. Key words: Apple, weed, density, frequency and general coverage. INTRODUCTION Turkey has a considerably fruit production potential due to its suitable ecological condition and it is ranked at the third place after China and USA with its 69.49.000 tons annual apple production (Anonim, 0). In apple farming, Isparta is ranked at the first place with its 634,795 tons output and then Karaman and Niğde followed with their production 388,400 tons and 37.7, respectively. Kahramanmaraş is ranked at the 0 th place with the area of 56.060 ha, and it is ranked at the th place with the production of 97.673 tons (Anonim, 03). Many factors affect the productivity and quality of the apple production and one of the most important of these is weed. Zeki et al. (994) reported that Cynodon dactylon L., Digiteria saguinalis (L.) Scop., Alopecurus spp., B. tectorum L., Sorghum halepense (L.) Pers. were founded densely as narrow-leaved weeds and C. arvensis L., Acroptilon repens (L.) DC., Cirsium arvense (L.) Scop., Sinapis arvensis L. Daucus carota L., C. album L. and Tribulus terrestris L. were founded densely as broad-leaved weeds in the apple orchards at the region of Ankara, Adana, Samsun in İzmir. Weeds such as A. myosuroides Huds., Amaranthus spp., Anagallis arvensis L., Anthemis spp., Avena spp., Bromus spp., Capsella bursa-pastoris (L.) Medik, C. album L., Convolvulus arvensis L., C. dactylon L., Cyperus rotundus L., Lolium spp., Malva spp., Poa spp., Rumex crispus L., S. arvensis L. and S. halepense (L.) Pers. caused problems in fruit orchards in Turkey (Tepe, 997). According to Yazlık and Tepe (00), there were 8 species of weeds belonging to 8 different families in apple orchards in Van region and they consisted of 37. weeds per square

Academia Journal of Agricultural Research; Tamer 676 meter. Poa annua L., Trifolium spp., Lolium perene L., Lotus corniculatus L. and Taraxacum spp. were densely determined weeds. A total of 09 species of weeds belonging to 3 different families were determined in the apple orchards at the region of Karaman and their density was 98.06 m (Karaca and Güncan, 003). A. retroflexus L., C. album L.and C. arvensis L. were highly densed and Seteria viridis (L.) P. Beauv. and S. arvensis (L.) P. Beauv. were densely detected. Akbolat et al. (007) stated that some species such as A. retroflexus L., C. album L., Xanthium strumarium L. and C. arvensis L., were detected at the high density; Sonchus oleraceus L., T. terrestris L., S. arvensis L., A. repens (L.) DC. and A. repens (L.) P.Beauv. were at medium density in the apple orchards at the region of Isparta. According to Üstüner and Akyol (007), 87 species of weeds belonging to 8 different families were detected and approximately 0.8 species of weeds was estimated per square meter in Nigde's apple orchards. From these 87 weed species, of them was fern plant (Pterydophyta), of them were monocot (Monocotyledon) and 75 of them were dicots (Dicotyledon). In terms of density at the unit area, A. repens (L.) P. Beauv., A. myosuroides Huds., B. tectorum L., and C. dactylon (L.) Pers had high density and related with the frequency of occurance, A. repens (L.) P. Beauv. was the most occurring weed species (84.6%), B. tectorum L. (7.%), A. myosuroides Huds. (54.9%) and Dactylis glomerata L. (49.%) followed. Junk et al. (997) reported that C. album L., C. bursapastoris (L.) Medik, Alopecurus aequalis Sobol and Erigeron canedensis L. had high density in Korea's apple orchards. According to Dastgheib and Frampton (000), Malva spp., Solanum nigrum L., C.album L., A. retroflexus L. and C. arvense L. were densed at the region Nelson in New Zealand. Harrington et al. (000) stated that annual weeds especially Solanum.nigrum L., C.album L., Veronica persica Poir., Polygonum aviculare L. and Coronopus didymus (L.) Smith were highly densed and perennial weeds such as Crepis capillaris (L.) Wallr., Picris echioides L, Trifolium repens L., Plantago lanceolata L., Bromus willdenowii Kunth and Rumex obtusifolius L were densely found in New Zealnd s apple orchards. Perennial and annual weeds caused problems on the fruits and vegetables in Nigeria and perennial species were Commelina beghalensis, C. dactylon (L.) Pers., Digitaria scalarum, Cyperus esculentus, C. rotundus L., Eleusine indica, Solanum incanum, Imperata cylindrica, Panicum spp., Mimosa spp., Lantana camara, and annual species were Maranthus spinosa, C.album L., S. nigrum L., Avena fatua L., Eleusine indica, E. colonum, Ageratum conyzoides and Polygonium ariculare (Hamma and Ibrahim, 03). In order to determine the effect of the harms of weeds on the culture plants, the first step to be determined should be weed species in control of the weeds. Different weed species respond to the different control methods. The challenge without recognizing weeds will be unsuccessful and this will cause waste of time, money and environmental pollution of herbicide. The most susceptible phase of the weeds is their 3 to 5 leaf stages in the chemical control. So, recognizing the life sateges of the weed will help in determining the control methods. In this study, identification, densities, frequency of occurence and coverage of weeds in the apple orchards in Kahramanmaraş were detected. MATERIALS AND METHODS In the study, surveys were applied in the apple orchards in Kahramanmaraş region (Center, Afşin, Andırın, Çağlayancerit, Ekinözü, Elbistan, Göksun, Nurhak, Pazarcık and Türkoğlu) in 0 to 03. Considering the distribution and density of the apple orchards in the region, 0 sub-region were selected and the samples obtained from these sub-regions. In the survey, it was considered at least 3 km among the gardens and the samples were obtained from 5 m inside of the edge of the garden. Within the da area, 4 frames ( m ) were used and weeds were obtained and counted (Odum, 97). The number of weeds in the m was calculated by dividing the total number of each species in m to the survey area. Weed density was calculated using the formula: Density =B/n formula (Güncan, 00). Here; B= Total weeds number in the sample, n= Number of sample. In the evaluation, broad-leaved weeds were considered as whole plants while narrow leaved weed were considered as their stems and recorded on the survey cards. Species, numbers and coverages of weeds were recorded and frequency of occurrence, number of plants and general coverages of obtained data were calculated using the following formulas: Frequency of occurrence (F.O.): The percent of the occurance of the weeds (%) in an area. Frequency of occurrence (%) = n/m 00 n: the number of the orchards containing species. M: total number of the orchard measured Species coverage (T.K.A.): It is expressed as the average value of any species of weed covered surface. This is calculated using the formula: G.K.A (%) = T.K.A./m G.K.A.: General coverage, m: Total number of survey. Table shows the survey studies were applied. Because fruit trees are perennial, both summer and winter weeds grow in the apple orchards. Therefore, a total of 666

A total of 33 species of weeds belonging to 3 different families were identified and their average density was.486 weeds/m. One species of these belonged to the ferns (Pterydophyta), of these were monocot (Monocotyledone), and of these were dicots (Dicotyledone). The densities of weeds were determined in the apple orchard in the sub-regions of Göksun (77.98), Elbistan (6.9), Ekinözü (5.946), Afşın, (0.34), Center (7.943), Çağlayancerit (4.898), Nurhak (97.753), Türkoğlu (89.38), Andırın (85.95) and Pazarcık (69.505), respectively. With regards to the average densities in the unit area, A. repens (L.) P. Beauv. (3.76 piece plant/m ), C. album L.(.73), B. arvensis L.(.03), A. retroflexus L (0.758) were determined and found to be highly densely present (average plant in m >0). However, C. dactylon (L.) Pers. (9.48), A. myosuroides Huds. (9.064), C. arvensis L. (6.80), D) glomerata L. (4.537), B. tectorum L. (4.4), L. serriola L. (3.938), S. viridis (L.) P. Beauv. (.50), D. Sangunialis (L.) Scop.

While B. arvensis L. was less than 50% in the Center was more than 5% in other 9 sub-regions. A. Myosuroides Huds. were defined to be more than 50% in the sub-regions of Andırın, Center, Çağlayancerit and Göksun, and less than 50% in the other 6 sub-regions. C. arvensis L. was also detected in the Center with 55.6% ratio. Coverages of the weeds varied from 0. to 48.% for the species of A. myosuroides Huds., A. Retroflexus L., A.repens (L.) P. Beauv., B. Arvensis, C. album L., C. arvensis L., C. dactylon (L.) Pers. and L.serriola L. Coverages of the other weeds were less than 0%. Species and densities of the weeds that caused problems in the apple orchards in Kahramanmaraş showed differencies according to the sub-regions. Some species were distributed in all regions while some species were distributed regionally. A. Repens (L.) P. Beauv. was determined at high density (average plant number in m 0) in all the sub-regions. C. Album was observed to be highly densely present in the sub-regions of Afşin, Çağlayancerit, Ekinözü, Elbistan, Göksun and Nurhak while it was densely present in the sub-regions of Center, Pazarcık and Türkoğlu. It was less densely populated (average plant number in 0. to m ) in the Andırın. B.

Kahramanmaraş region is located in the Mediterranean region and Continental climate zones. Therefore, while Center, Pazarcık and Türkoğlu sub-regions are located in the Mediterranean climate, Andırın and Çağlayancerit are located in the transition climate. However, Göksun, Afşin, Elbistan, Nurhak and Ekinözü have a continental climate. Species number of the weeds in the regions of Mediterranean climate was determined more than the continental climate regions. In addition, the region has different soil structure types. The ph of the soil in the region varied from 7.06 to 8.33 and generally it is 7.60. From the examining soil profile, 8 of them was saltfree, 3 of them less saline and of high saline. KDK of the soils varied from 0 to 80 me/00 g and generally between 30 and 40 me/00 g. The dominant cation was calcium and this was followed by magnesium, potassium and sodium, respectively. Calcareous contents of the region were generally less than 5% (Yılmaz et al., 990). The weed density in the Göksun subregion was found to be much more than that of the other subregions because it has 6 times larger apple orchards area than the other subregions. Because Pazarcık subregion has the smallest apple orchads area, its weed density was found to have less density. Determined density, frequency of occurance and coverage of some the species of weeds varied according to subregions. In this study, densities of the perennial plants with rhizome and stolon were especially found with high densities. Densities of Cyperus spp. and P. Oleracea in the Mediterranean region were roperted as the most common weeds especially in the summer season (Kadıoğlu and Ulu, 993). Frequency of occurrence of Stelleria media, Matricaria chamomille, Oxalis spp., Poa annua and Lactuca serriola were more than 50% in March and April in the same study. In Aydın region, 47 weed species belonging to 0 families were reported by Öğüt and Boz (007) and frequency of occurrencies were 79.80% for S. media, 63.60% for M. chamomilla, 55.50% for O. corniculata, 5.80% for P. annua and 50.0% for L. serriola in the dormant season. During the summer season, frequencies of occurrence of P. oleracea, C. rotundus and Amaranthus spp. were 87.80, 85.80 and 63.30%, respectively. Frequencies of occurrence of T. terrstris, C. dactylon, C. arvensis, D. sanguinalis, L. serriola, C. album, E. crus-galli and S. halepense varied from 0 to 45% while the other weeds were in between and 0% frequencies of occurrence. The coverage of the weeds were 56.5% for P. oleracea, 5.70% for Cyperus rotundus,6.6% for C. dactylon, 6.54% for Trifolium spp., 3.39% for D. sanguinalis, and.74% for Amaranthus spp. (Öğüt and Boz, 007). A total of 47 weed species belonging to 9 families were identified on the apple orchards in Niğde. Six species of these belonged to monocotyledone and 4 of them belonged to dicotyledons (Ustuner and Ustuner, 0). In the survey studies in Isparta's apple orchards, 6 species of weeds belonging to 3 families consist of one seedless, two monocotyledons and 0 dicotyledons. Densities of A. retroflexus L., P. oleracea L. (8.9) and Setaria verticillata (L.) P.B. were detected as 0.56, 8.9 and 4.79%, respectively. The coverage areas were 5.4% for A.

Academia Journal of Agricultural Research; Tamer 690 retroflexus, 3.69% for Tribulus terrestris L. and 3.00% for P. oleracea. The most common weed species in the apple orchards were 83.33% for C. album, C. arvensis L. and P. oleracea, 77.78% for A. retroflexus and 77.% for L. serriola L. (Kitiş, 0). Densities and frequencies of occurrence of weeds in Turkey were reported by Kadıoğlu and Ulu (993), Zeki et al. (994); Tepe (997); Yazlık and Tepe (00), Karaca and Güncan (003) Üstüner and Akyol (007), Öğüt and Boz (007) and Kitiş (0). The results of these studies were similar with our results. Majority of the weeds were A. repens (L.) P. Beauv., A. myosuroides Hudson, Amaranthus spp., B. tectorum L., C. album, C. dactylon (L.) Pers., S. viridis (L.) P. Beauv., D. glomerata L., C. arvensis, M. chamomill, L. serriola, S. Halepense and D. sanguinalis. However, the species of Trifolium spp., Lolium perene L., Lotus corniculatus L., Taraxacum spp., P. annua L., P. lanceolata L., Stelleria media, O. corniculata, P. Oleracea, C. bursa-pastoris, C. rotundus, E. crus-galli and T. terrstris showed differences according to the region. The reason of these differences is due to different climate conditions, irrigation systems, soil type and altitudes of the regions. The results of the present study were also consistent with the results of the studies carried out in different regions in the world (Jung et al., 997; Dastgheib and Frampton, 000; Harrington et al,, 00; Hamma and Ibrahim, 03). A. retroflexus L., A. repens, C. album L. and C. arvensis in the present study were similar with the species in the previous studies. Some of the factors such as the altitude, soil structure, climate, irrigation system and plant communities of the region played a role in these similarities. Consequently, densities, frequency of occurrence and coverage of the weeds may be different according to the region. These numerical values may also vary in the same region. These factors such as altitude, climate, soil structure, irrigation systems, tree corolla width (shadowing) and plantation area's size of the region may play a role in the emergence of this variation.
