Studies For Increasing Fertility On Second Crop Of Rice, Nazimi Açikgöz, M. N. Gevrek

Turkish Journal of Agriculture and Forestry

C Selection was done on the basis of certain morphological, phenological and technological properties, in the studies conductted for increase of fertility in second crop of rice under Menemen ecological conditions during the year 1990-1991. Amongst 16 genotypes studies 2 genotypes found suitable for second crop of rice due to their resistance against extremly high temperature which causes sterility and determined as having high fertility were sent to "Variety Testing and Relies Institute Ankara". The project was completed with the second year success in the regional varietal yield.

Turkish Journal of Agriculture and Forestry

In this study, the possibilities of the utilization of waste water of Gemlik Fertilizer Inc. in agriculture was investigated. With this aim, three-years field trials were carried out at the Experimental Farm of Agricultural Faculty, Uludag University. A considerable increase in the electrical conductivity of the soils irrigated with waste water was observed while ph of these soils was decreased. Although relatively lower tomatoe yields were obtained from the plots irrigated with only waste water, the yields obtained from the plots irrigated with normal irrigation water mixed with waste water at different rates were higher than those of the plots …

Relationship Between Clay Minerals And Potassium Statuses Of Sugar Beet Cultivated Area Soils Of Kastamonu And Amasya Sugar Factories, Nuri Munsuz, Gökhan Çayci, Mümtaz Ki̇bar, Nihat Akinci, İlhami Bayrami̇n, Kamil Erel

Turkish Journal of Agriculture and Forestry

In this study, clay minerals and their relationships with potassium statuses of sugar beet cultivated area soils of Kastamonu and Amasya Sugar Factories were investigated. Research was carried out on ninety seven surface soil samples taken from Kastamonu and Amasya regions. As a conclusion, illite clay mineral which is the main resource of reserve potassium in soils was found less dominant than that of levels of smectite and kaolinite, particularly a drastic illite degradation was observed in Amasya region soils.

Turkish Journal of Agriculture and Forestry

In this research the fertilization biologies of mid and late flowering 4 almond types (101-9, 101-13, 101-23 and 106-1) selected from different parts of Turkey and Texas cultivar were studied. For this purpose, first of all, pollen viability tests with TTC and FDA and pollen germination tests in 0 %, 5 %, 10 %, 15 % and 20 % sucrose mediums by hanging drop method were performed. On the other hand, the amount of pollen production and their morphological homogenity levels were determined. In addition, besides self and open pollinations with cross pollinations the pollen tube growth rates were investigated. …

The Effects Of Bottom Heating On Rooting Of Hardwood Cuttings With Different Number Of Buds Of Some Grapevine Rootstocks Resistant To Nematodes, Semih Tangolar

Turkish Journal of Agriculture and Forestry

In this experiment, the effects of bottom heating on rooting of hardwood cuttings with different number of buds of Dog Ridge, Salt Creek, Harmony, 1616 C and 1613 C which are nematode-resistant rootstock varieties were investigated, and rooting percentage, degree of rooting, total number and length of roots were determined. The highest values were obtained from the bottom heated cuttings with had three and four buds. The results showed that 1616 C had superior rooting ability than the other rootstocks in all characteristics tested. The rooting percentage was about 80-90 % and the rooting quality was sufficient, bottom-heated Salt Creek …

Turkish Journal of Agriculture and Forestry

Differents colchicine doses (0.5 % and 1 %) and treatment periods (1, 2, 4 and 6 hours) were tested in vitro conditions in order to obtain dihaploid lines from parthenogenetic haploid plants which achieved by irradiated pollen. Treatments were made to 3-4 weeks age in vitro microcuttings of Sugar Baby, Halep Karasi and Crimson Sweet varieties. 64 percent of the plants treated with 0.5 % colchicine stayed alive and 56 % of the plants were developed into a new plant. At the doses of 1% the rate of alive and growing plant decrease to 40 %. As for as the …

Turkish Journal of Agriculture and Forestry

According to the results obtained from two years rotation experiment, which was carried out under Ankara-Haymana dryfarming conditions during 1991-1993, conclusions can be summarized as follows: Soil water contents measured during vegetation period as well as at harvest time of six previous crops were significantly different in the first year of the rotation. At harvest time of previous crops and planting time of wheat, higher soil water content found in fallow plots in comparison to winter sown legumes (lentil, vetch, pea and Hungarian vetch). Oil radish and mustard as other previous crops, led to the lowest soil water content. In …
