This study was carried out in Konya Soil, Water and Combating Desertification Research Station in 2015 in order to determine the effect of humic acid applications in different amounts on the development and quality properties of some potato varieties in Konya ecological conditions. Three different potato varieties (Agria, VR808, Brooke) and four different humic acid doses (0, 3, 6, 9 L da -1 ) were used in this study, which was established in three replications according to "The Randomized Complete Block in a Split Plot Design". In the study, large, medium, small, discarded tuber yields per decare, protein content, specific gravity, chips yield, oil holding capacity of chips, dry matter content, starch content were investigated. It was determined that there was a significant increase in humic acid applications in large, medium, small and discarded tuber yields per decare. Oil holding capacity of chips was between 32.9 % and 46.2 %, starch content was between 11.7 % and 17.3 %, and the differences between humic acid applications were found to be statistically significant for these properties. In terms of chips yield and protein content, statistical significance was not determined among the applications. Considering all the properties examined, it was determined that increasing humic acid applications positively affected the yield of large, medium and small discarded tubers per decare and significant variations were obtained among some quality properties of the varieties.

The experiment was implemented to evaluate the yield and quality properties of potato varieties and candidate genotypes were examined in 2019 growing seansons under Yenisehir-Bursa conditions. The experimental design was a "Randomized Complete Block Design" with three replications. Eight potato candidate genotypes ("EA10", "GAF4", "MK-2", "AH-11", AFK-3", "AA12", "HA5", "LOH3Y") which were developed by Associate Proffessor Rahim Ada and four potato varieties (Marabel, Florice, Melody, Lady Olympia) were used as plant material in this experiment. The plant height (cm), number of stem per plant, number of tuber per plant, total tuber yield (t ha-1), dry matter content (%), yield of chips (%), yield of french-fries (%) were examined. According to results of this experiment, significant differences were found in all properties among the potato varieties and candidate genotypes statistically. The plant height changed between 48.3-107.3 cm, number of stem per plant was 4.6-10.0, number of tuber per hill was 4.3-16.6, total tuber yield per hectare was 8.9-52.1 t. In addition, dry matter content changed between 16.7-25.0 %, yield of chips was 36.1-60.3 %, yield of french-fries was 55.0-70.8 %. The highest total tuber yield was obtained from Florice variety (52.1 t ha-1) and "GAF4" potato candidate genotype (49.6 t ha-1) and the lowest total tuber yield was obtained from "AFK-3" potato candidate genotype (8.9 t ha-1, respectively). The experiment results indicated that "GAF4" potato candidate genotype was found promising.

The main objective of the experiment was determined suitable sunflower candidate genotypes. The experiment was conducted under Konya-Ilgın conditions in 2018 growing seasons in Randomized Complete Block Design with three replications. The experiment materials were the sunflower candidate genotypes which were developed by Associate Proffessor Rahim Ada and some sunflower varieties. The observations were made hull ratio (%), oil content (%), protein content (%). According to the results of the experiment, significant differences were found in all properties among the varieties and candidate genotypes statistically. The hull ratio values were obtained from 4CMS X

This study was aimed to determine the effects of treated iron doses on agricultural characteristics by appyling foliar in some peanut varieties (NC-7 and Sultan). It was conducted at different times (flowering period and pod formation period) and doses (control, 400 kg da -1, 500 kg da -1, 600 kg da-1) in the farmer's field in the Göçmenler district in the Hardallık village of Kadirli, Osmaniye, in April and September of 2020. The study was arranged in a "Split-Split Plots Experiment Desing" with three replications, and varieties to the main parcels, treatment time to the sub-parcels, iron doses to the sub-sub-parcels, were treated. In the study, variety, dose, varietyxdose, timexdose, varietyxtimexdose interactions were found to be statistically important in pod yield. In terms of number of pod per plant, 100 pod weight, 100 seed weight; varietyxdose, timexdose, varietyxtimexdose interactions are important, however in the seed ratio these interactions turned out to be statistically insignificant except from variety. According to the results obtained, the highest pod yield was obtained as 521.1 kg da-1 from treatments of Sultan varieties in terms of varieties; it was obtained as 544.5 kg da -1 from pod formation period and 400 kg da -1 dose in the terms of varietyxtime interaction and it was obtained as 512.6 kg da -1 from 400 kg da-1treatment in terms of dose. As a result; for both periods in order to achieve high pod yield in peanut cultivation, 400 kg da -1 iron dose treatment and Sultan variety in Osmaniye conditions can be recommended.

The purpose of this study was to determine the potato breeding lines that show superior storage traits and can be candidate variety by selection. The storage study was carried out in the first year according to the The Randomized Plots Trial Design and in the second year according to The Randomized Plots In Factorial Trial Design with four replications. In the study, 20 potato breeding lines developed by Selcuk University, Faculty of Agriculture, Department of Field Crops and 18 registered varieties as plant material were used in the first year. In the second year, the study continued with 7 breeding lines and 8 registered varieties that selected at the first year. The varieties and lines were done harvest in the fields and then the genotypes were evaluated according to physical and quality traits with storage trials (+ 4 °C, 6 months). In the study; ratio of dry matter (%), yield of leaf chips (%), yield of French fries (%), quality of leaf chips (1-5 scale), quality of French fries (0-4 scale), blackening (1-5 scale), storage weight loss (%), the first shoot formation time (day) parameters were examined. The ratio of dry matter, yield of leaf chips and yield of French fries values increased compared to the pre-storage period. Among the promising lines in terms of dry matter ratio changes; T7LA8 (20.9 %-24.8 % in 2019,19.0 %-21.1 % in 2020 according to the genotype average values), PAG5 (22.6 %-20.5 % in 2019, 20.0 %-19.0 % in 2020 according to the genotype average values), GAF4 (18.7 %-21.6 % in 2019, 18.4 %-20.7 % in 2020 according to the genotype average values) can be counted. As a result of the study, T7LA8, PAG5 and GAF4 lines with high ratio of dry matter, yields of chips and French fries were determined as promising lines.
