In this research, the root parameters of pepper plant (Capsicum annuum L.) grown at four different growth media prepared with different rates of soil and peat were investigated. According to experimental results, with increasing the peat content, root lenght, root area, root volume, root and shoot weight were decreased whereas shoot/root ratio was increased. It was found that changes in all root parameters, except root diameter were significant statistically, (P<0.05).

Key Words: root parameters, plant growth media, peat, pepper (Capsicum annuum L.)

(Turkish)

The salts transported to the soil with irrigation water effect the crop yield in different ways. It can effect soil physical conditions or effect directly to the crop with its ions which are toxic to the crop. In general yield decrease of the crop is closely related to the salt tolerance. In this greenhouse experiment, the effect of irrigation water salinity on some yield parameters of pepper were investigated for different growing periods. The results showed that; 3.0 dS/m salinity level did not effect the germination and the seedling biomass contents, but increased to the seedlings heights as 13%. The salinity during the growing period, however, decreased the yield and the biomass content of the fruit. The fruit height and the total ash contents were also affected by the salinity. The total ash contents of leaves ant petioles, however, were not affected by the salinity at the level of %5. The interactions of the experimental factors were not statistically important on the yield parameters studied.

Key Words : salinity, pepper, salinity-yield relation, salinity on germination

The aim of this study was to determined the effect of inbreeding on production traits in Brown Cattle. In this study data for the production records collected through the years 1968-94 from Brown cows kept at the Regional Agricultural School in Van. The records used were adjusted to systematic environmental factors. At first, the coefficient of inbreeding for each individuals was calculated by using Wright's technique. And then the effect of inbreeding was analysed by calculating the regression coefficients of traits on inbreeding coefficient. The environmental effects were simultaneously evaluated by the least squares method. Mean coefficients of inbreeding were about 6.89±0.89% ranging between 0% and 36.99%. Effect of inbreeding on 305 days milk yield and lactation length were highly significant (P<0.05), whereas effect of inbreeding on dry periods wasn't significant (P>0.05). The correlations between 305 day milk yield, lactation length and dry periods and coefficients of inbreeding were -0.1816±0.0363, -0.1206±0.0217 and -0.1500±0.0180 respectively, and the regressions of above traits on the coefficients of inbreeding were -15.30±3.07 kg, -1.00±0.30 kg and 1.87±0.61 days respectively. The correlations between age at first mating, age at first calving, calving interval, service period and the coefficients of inbreeding were 0.1285±0.0283, 0.1029±0.0247, 0.0352±0.0088 and 0.0583±0.0157 respectively, and the regressions of this traits on the coefficients of inbreeding were 1.903±1.600 days, 1.461±1.419 days, 0.274±0.546 days and 0.329±0.581 days respectively. Effect of inbreeding on reproductive traits weren't significant (P>0.05).

The purpose of this study is to determine the milk and reproductive traits performance of Brown Cattle raised at state farm in Altındere. Abortus and still birth percentage were 1.23% and 0.62%. Overall means of age at first calving were as 1097.5±21.6 days. The least squares means of service period, calving interval, number insemination per pregnancy, mature equivalent milk yield, lactation length and dry periods in the herd were as 149.25±15.94 days, 434.94±16.15 days, 1.48±0.08, 2230.48±88.46 kg, 229.68±4.44 days and 209.47±22.73 days, respectively.

The effect of increasing applications of nitrogenous and phosphorous fertilizers into soil and interactions between nitrogenous and phosphorous fertilizers on the N, P, K, Ca, Mg, Fe, Cu, Zn and Mn contents in spinach plant were found to be statistically significant at 1% level. Ca, Fe, Cu, Zn an Mn contents of spinach plant were decreased by increasing applications of nitrogenous and phosphorous fertilizers. N and Mg contents of plant were increased by increasing application of nitrogenous fertilizer, while P, content was increased by increasing applications phosphorous fertilizer. It was determined that N, P, and Ca contents of spinach plant growing in certain nitrogen and phosphour treatments were found to be below of the critical concentrations as the obtained data compared with literature for spinach plant.

Uludağ University, Department of Soil Science-Bursa

This study was implemented to determine effect of iron chlorosis on mineral composition of peach trees. For this purpose, leaf samples were taken separately from trees indicating different degree of chlorosis in four orchards in two years period. According to results obtained from the experiment; It was shown that, active iron was the most appropriate method in diagnosis of iron chlorosis as compared with total iron. There was no significant relationship between iron chlorosis and Ca, Mg, Zn Cu and Mn concentrations of leaves, whereas P/Fe, K/Fe, K/Ca, Zn/Fe and Cu/Fe ratios were significantly affected by iron chlorosis and it could be suggested that these ratios would be used as an index of iron status of peach trees.

Key Words: peach, iron, chlorosis, plant nutrients

This study ws undertaken to determine the effect of hydrogen peroxide on total bacteria, coliforms and yeast and moulds in milk and its products of unsalted curd, ripened cheese and wheys. For this purpose, the raw milk at 30+10C was divided into four equal parts and (i) raw milk without hydrogen peroxide (control) and those treated with hydrogen peroxide at the levels of (ii) 0,02 %, (iii) 0,10 % and (iv) 0,30 % were made into pickled white cheese after seing kept for 4 hours at the above mentioned temperature. Microbiological analysis was carried out in the milk samples which was taken intially and after 4 hours and in the cheese samples kept for 0, 4, 8 and 12 weeks in order to examine the changes caused by hydrogen peroxide. Unsalted curd and whey samples were also subjected to the same analysis. It was determined that the treatment of milk with hydrogen peroxide caused a reduction in the counts of total bacteria, coliform and yeast and mould organisms within the first 4 hours depending upon the concentrations used. On the contrary, the number of those organisms mentioned above in the control samples increased rapidly. The microbial content of unsalted curd and whey decreased with the increasing amounts of hydrogen peroxide. The microorganisms in cheeses obtained from hydrogen peroxide treated milks were found to be lower than that of the control cheese during the ripening period.

Key Words: Hydrogen peroxide, white cheese, whey, total bacteria, coliform microorganism
