Bu nedenle pamuk yetiştiriciliğinde istenilen düzeyde ve kalitede ürünün elde edilmesi için diğer besin maddeleri yanında bu bitkinin Mg ve S isteğinin de iyi olarak karşılanması gerekir. Araştırmada materyal olarak önemli pamuk yetiştiriciliği bölgesini oluşturan Gediz ovasından alınan ve besin maddeleri kapsamları farklı olan iki toprak ele alınmıştır. Bu toprakların önemli bazı fiziksel ve kimyasal özelliklerini gösteren analizler yapılmıştır. Analiz sonuçlarına göre, toprakların diğer özellikleri yanında Mg ve S kapsamları da önemli derecede farklıdır ve 1 numaralı toprağın alınabilir S ve Mg kapsamının sırasıyla 36.88 ppm ve 5.19 meq/100 g olmasına karşılık, 2 numaralı toprak için bu değerler yine sırasıyla 13.38 ppm ve 1.38 meq/100 g'dır.In comparison with the most of the plants, Mg and S requirements of cotton is relatively higher. Therefore for high yield and good quality it, is necessary to meet Mg and S requirements of this plant in best way. In this investigation as materials two soils taken from cotton growing region in Gediz plateau were used. Some important physical and chemical properties of these soils were determined. According to the results of analysis these soils, beside other properties, different markedly also in their Mg and S contents. However S and Mg content of soil 1 was 36.88 ppm and 5.19 meq/100 g whereas for soil 213.38 ppm and 1.38 meq/100 g respectively. A greenhause experiment was conducted using randomized block desing with three replicates for each treatment and both S and Mg were applied as 3 levels. For a healty growth of plant, in addition necessary N,P and K were added to the pots. Seeds were planted at 5.3.1980 and as seed Coker 100 A/2 was used. After thining 6 plant were left at each pot. During growing period water, heat and light factors were kept under control, in addition necessary phenological observations were also made. At 23.5.1980 the plants were harvested and after harvest the amount of yield obtained from each pot was determined, S and Mg analysis in plant materials were made. The results of the experiment can be summarized as follows: 1. Yield: In comparison with control, the amount of yield was not affected by either S or by Mg treatments markedly, even yield was decreased with the effect of some treatments. 2. S content of the plant: All S levels increased S content of the plants in both soils and the highest increase was obtained by S,level. 3. Mg content of the plant: In comparisot. with control, all Mg levels caused an increase in Mg content of the plant and the highest increase was obtained for soil 1 at Mg(1), and for soil 2 at Mg2 level. 4. Combined effects of S and Mg on S and Mg contents of the plant: For S content of the plant Mg(2)S(2) treatment for both soils was found most effective, whereas in respect of Mg for soil 1 Mg(1)S(0), for soil 2, Mg2S(1) treatment was found superior with the others. On the other hand according to the LSD values differences found between all treatments were statiscally highly significant (0.01 level).turinfo:eu-repo/semantics/openAccessAgricultureTarımSoilToprakCottonPamukGedizreport
