This study was made to model annual flow series measured on Çorum Cat Stream. ARMA (p,q) models were used in modeling annual flow series. In selecting appropriate model, It was taken into account whether the residuals calculated from ARMA (p,q) models were independent. For annual flow series, ARMA (2,2), ARMA (1,1), ARMA (3,1), ARMA (2,2), ARMA (1,3) and ARMA (3,0 models were appropriate. The sum square differences were extracted for the observed flows and the flows forecasted from the selected models. The lowest value of these sum square differences was obtained from ARMA (1,3) model. Therefore, ARMA (1,3) model was more suitable in forecasting annual flow series of Çorum Cat Stream.

Key Words: flow, autocorrelation, partial autocorrelation, ARMA (p,q) model

(Turkish)

M. Rüştü KARAMAN
Gaziosmanpaşa University, Faculty of Agriculture, Department of Soil Science-Tokat

The availability of Fe in calcareous soils may be increased by application of humic substances with iron fertilizer. For example, application of humic substances to peach trees may increase Fe availability and decrease the cost. In this study, effect of different iron and humic substances on the availability of iron (on the decreasing of iron chlorosis) in peach trees on calcareous soil of Tokat region was investigated. Soil applications of inorganic Fe, humate and Fe-humate had less effect than FeEDDHA (synthetic chelate) on the decreasing of Fe chlorosis under these calcareous conditions. But, because of the high cost of synthetic chelates, cultural expedients also seems to be valuable and economical.

This incubation study investigated the effects and interactions of ammonium and potassium fertilization on their fixation by soil. Fixation of the ammonium or potassium increased when applied alone, which however making the other more available. In this case, increase in the fertilizer dose resulted in increased fixation. When the fertilizers were applied together, the potassium fixation was greater than that of ammonium. When compared with the single application, the amount of ammonium fixed by soil was less, and that of potassium remained similar.In case of applying the ammonium first and the potassium ten days later, or vice versa, the fixation of potassium was not statistically altered. On the other hand, applying the potassium first significantly decreased the ammonium fixation Experimental results have shown that application of first potassium than ammonium to a soil might reduce the fixations of these ions if the priorty of fixation of potassium or ammonium is not crucial.

Key Words: ammonium, potassium, fixation, alluvial soil

In this study, length and weight compositions, weight-length relationships according to sex groups, health condition and crayfish catch per trap, density and biomass together with the size of crayfish population (Astacus leptodactylus Esch. 1823) in Dikilitaş Irrigation Reservoir were investigated. In the estimation of the size of crayfish population, mark-recapture method (Petersen Method) was used. To estimate the size of population, crayfish were captured in dates of 08.10.1999 and 12.10.1999. Then, 1500 and 1639 crayfish were marked individually with the water resistant paint. 6.77 % and 6.87 % from marked crayfish were recaptured in 12.10.1999 and 15.10.1999. Population sizes according to marking dates were estimated as 23843±2185 (21658-26028) and 18011±1567 (16444-19578) individuals, respectively. Density and biomass of crayfish in Dikilitaş Irrigation Reservoir were found as 199 (180-217) inds./ha and 6.47 (5.88-7.06) kg/ha for I. experiment and 150 (137-163) inds./ha, 4.91 (4.49-5.34) kg/ha for II. experiment, respectively. Length values of crayfish were found to vary between 75-145 mm and the mean length according to sex groups were determined as 102.50±0.35 mm for male and 102.04±0.34 mm for female. Small individuals more than 90 mm were comprised 22.62% of crayfish population. Weight values of crayfish were found to vary between 10.00-92.50 g and the mean weight according to sex groups were determined as 33.11±0.35 g for males and 32.24±0.33 g for females. Weight-length relationships according to sex groups were determined as W=3*10-5*L3,0092 (r=0.9944, n=2122) for males and W=2*10-5*L3,0797 (r=0.9950, n=2298) for females. During the research, the mean catch per trap per day of captured crayfish from Dikilitaş Irrigation Reservoir were calculated as 2.23 ± 0.08 inds./trap/day. In the macroscopic examination of crayfish, it was seen that they have had disease symptoms. The ratio of the individuals with symptom was determined as 3.01%.
