N.MORDOĞAN 1, Ş.CEYLAN 2 , F.YOLTAŞ 2 , H.ÇAKICI 1 1 Ege University Faculty of Agriculture Department of Soil Science, Bornova, İzmir. 2 Ege University Ödemiş Technical Training College, Ödemiş, İzmir. Abstract The study was carried out in Ödemiş District of İzmir, Ege University Ödemiş Technical Training College. Experimental side, where red 'yağlık'pepper was used as the best crop. Cattle manure was applied in different Rate as: control, 2, 4 and 8 t da-1 with 3 replications. Planting density was 70x30 cm with 35 plants in each parcel. Seeds were sown on 15 May 2000. Manure was analyzed according to Kacar (1990). Texture (Selvaraj et. al.1998), Total soluble salts (Vural et. al., 2000), pH (Kacar and Katkat, 1999), CaCO3 (Soil survey staff,1951), Total N (g), available P (Bingham,1949), available K, Ca and Mg contents of the experimental soil were analyzed according to NH4O AC method (Kacar and Katkat, 1999) and organic matter (Soil survey staff,1951), available Fe, Cu, Zn and Mn according to DTPA method(Loue'1968). Material and Methods Kjeldahl method was used to determine the total N content of the leaf samples. Total P was measured spectrophotometrically; K and Ca with flame photometes (Kacar,1972) and Mg, Fe, Cu, Zn and Mn with atomic absorbtion spectrofhotometer.Yield and fruit quality properties were determined and the results are evaluated statistically. According to the table, pH of the soil is slightly acid, low in organic matter and lime and has no salinity problem. Similar results were found by different researchers (Jackson, 1967; Küçük,1992; Schlichting and Blume,1966; Vural et al,2000). Soil texture is sandy loam and has low N, P, K contents and Zn is in critical level. C/N ratio of the composted cattle manure is 19 . And also similar contents and C/N ratio were found in some experiments (Aydeniz & Brohi, 1991). Result and Discussion Results show that primary and secondary leaf nutrients increase which cattle manure rates increase compare to that of the control. Nitrojen contents of the leaves are found sufficient while P, Ca and Mg high and K low. Copper and Mn were sufficient in all of the leaf samples and Zn low in only the control and 2 t da-1 cattle manure application (Bergman,1986) The effect of cattle manure applications on leaf N, K, Fe and Ca contents were statistically significant at 5 and 1% levels. No effect was found in other studied leaf nutrients. Pepper yield increased by the application of manure. Maximum yield was in 8 t da-1 application. When compared to that of the control, 48% increase has been recorded. Maximum number of fruit in plant was determined in 2 t da-1application dose and the maximum fruit length was in 8 t da-1treatment. Average fruit weight, fruit thickness and fruit width varied in different application on doses and when compared to that off control they decreased. Treatments has been determined significantly (1%) affected the yield and fruit properties excluding fruit width. Selvaraj et al. (1998), reported higher yields when cattle manures are used in pepper growing. Bayraktar (1981), recommended 3-5 t da-1cattle manure for pepper. The same researcher has determined 10-40 fruit number and 100-1000g fruit weight per plant and 3000-3500 kg yield per decar. Küçük (1992), determined that maximum yield in 12 kgN da-1application in his investigation with different N doses. |
