Effects of Calcium Nitrate and Humic Acid on Pepper Seedling Growth Under Saline Condition
(Triveni Enterprises, 2010) Gulser, Fusun; Sonmez, Ferit; Boysan, Sibel
This study was carried out in order to determine effects of calcium nitrate and humic acid applications on pepper seedling growth under saline condition. A mixture of soil:sand (1:1) was used as a plant growing media including 90 mg kg(-1) P2O5, 180 mg kg(-1) K2O and 250 mg kg(-1) N. Four different doses of humic acid (0, 1000, 2000 and 4000 mg kg(-1)) and calcium nitrate (0, 50, 100 and 150 mg kg(-1)) were applied into the growing media. Before sowing Demre variety pepper seeds, 60 m mol NaCl was added into 300 cm(3) soil:sand mixture in each pot. Applications of humic acid and calcium nitrate significantly affected pepper seedling growth. 1000 and 2000 mg kg(-1) humic acid and 50 mg kg(-1) calcium nitrate applications increased fresh and dry leaf weight, fresh and dry root weight, stem diameter, root length and shoot length. The highest rates of humic acid (4000 mg kg(-1)) and calcium nitrate (100 and 150 mg kg(-1)) decreased these criteria of pepper seedling under the saline soil condition.
The Effects of Gytita on Plant Growth of Lettuce (Lactuca Sativa) in Nickel Contaminated Soils
(Parlar Scientific Publications (p S P), 2017) Gulser, Fusun; Sonmez, Ferit; Karaca, Siyami; Gokkaya, T. Hasibe
In this study, the effects of Gytjja on some yield criteria of lettuce (Lactuca sativa) grown in Ni contaminated two different soils (Inceptisol and Entisol) were investigated. This study was conducted with the application of three levels of gytjja (0, 5 and 10%) in two different soils (Inceptisol and Entisol) contaminated with three levels of Ni (0, 40 and 80 mg kg(-1)) in a factorial experimental design with three replications. As a basic fertilization, 300 mg kg(-1) N and 90 mg kg(-1) P2O5 were applied into each pot. At the end of the study, the highest value for plant length (20.50 cm), leaf number (16.3) and plant fresh weight (10.67 g) were obtained in the 10% gytjja without Ni application in Inceptisol soil. The plant growth parameters were higher in the Inceptisol soil than in the Entisol soil. According to the results, gytjja doses had the positive effects on plant growth criteria of lettuce in Ni contaminated soils. Ni applications decreased the mean values of plant growth criteria.
Effects of Humic Acid and Ca(No3)2 on Nutrient Contents in Pepper (Capsicum Annuum) Seedling Under Salt Stress
(Taylor & Francis As, 2016) Sonmez, Ferit; Gulser, Fusun
This study was carried out in order to determine the effects of calcium nitrate (Ca(NO3)(2)) and humic acid (HA) applications on nutrient uptake of pepper seedling under salt stress in a plant growth room. Before sowing Demre variety of pepper seeds, 60 mM NaCl was added to each 300 cm(3) pot. The experiment was ended at eighth week after the sowing. Applications of HA significantly affected K, Ca, Fe, Mn, Zn (p < .01) and P (p < .05) contents. Also, Ca(NO3)(2) applications did not show a significant effect on Fe and Cu contents of pepper seedling. However, Ca(NO3)(2) applications significantly affected N and P contents (p < .05) and K, Ca, Mn, and Zn contents (p < .01) of pepper seedling under salt stress.
The Effects of Humic Acid Application on The Nutrient Contents and Heavy Metals in Organs of Marigold (Tagetes Erecta L.)
(Parlar Scientific Publications (p S P), 2017) Sonmez, Ferit; Alp, Sevket; Yasar, Ozlem
This study investigated the effects of humic acid doses applied directly to the soil (control, 10, 20, 40 kg da(-1)) wherein yellow and orange tagates species were grown. The effect of humic acid on the concentrations of macro elements, micro elements and heavy metals in stalk, leave and flower were determined. At the end of the study, it was observed that applying humic acid had a significant effect of 0.1% on the concentrations of N, P, K, Mg, Na, Fe, Zn, Cu, Mn, Cd, Ni, and Pb. Additionally, there were significant differences seen in the nutritional elements content in plant organs, with N, K, Ca, Mg, Na, Fe, Zn, Cu, Mn, Cd, Ni, and Pb at a percentage of 0.1% and P at a percentage of 1%. It was observed that there was a significant difference of 0.1% in regards to the nutrient content of the elements K, Na, Zn, Cu, and Pb. There were no observable significant differences in the amount of the other elements. To conclude, it was determined that applying humic acid had a significant effect on the element contents of different tagates species as well as the nutritional element and heavy metal contents of plant species and their organs.
The Impact of Potassium Sulphate Application on Phaseolus Vulgaris Plants Grown Under Salt Stress
(Parlar Scientific Publications (p S P), 2018) Erdinc, Ceknas; Sonmez, Ferit; Ekincialp, Aytekin; Sensoy, Suat
The present study aimed to investigate the effects of potassium sulphate on certain bean genotypes after K2SO4 application based on the analysis of plant growth parameters and macro-micro nutrient element content. The study material included 1 bean genotype (Gevas) and 3 bean cultivars (Akman-98, Sugar and Onceler) obtained in Lake Van Basin of Turkey. The plants were grown under controlled conditions at 23 +/- 2 degrees C temperature and 8000 lux light intensity 12 hours light and 12 hours dark photoperiods, with 4 replicates and 8 plants per replicate and randomized lots design. The plants were grown under stress-free conditions until they reached the 3-leaf stage, after which they were exposed to a constant 20 mM salt stress. 500, 1000 and 2000 mg kg(-1) K2SO4 was mixed to the growth medium before seeding except the control plants. Study findings demonstrated the statistical significance of potassium sulphate application especially that of the 1000 mg kg(-1) and 2000 mg/kg-1 potassium sulphate doses, based on several parameters and its effects on the reduction of salt stress were observed. The variations between the genotypes were observed and it was determined that the genotype Gevas and cv. Onceler exhibited higher tolerance. Despite the other parameters, the nutrient element parameters such as K/Na and Ca/Na content and plant development parameters such as shoot dry matter and root dry matter content were effective in determination of the positive effects of potassium sulphate.

Based on average values of two years, pistachio selections had 1.21-1.93 g fruit weight, 0.46-0.81 g kernel weight and 31.5-49.0 % kernel percentage. Their splittings were high, medium and low. Harvest time was between 20 September and 05 October. Fruits of selections contained 3.04-4.20 % N, 0.168-0.441 % P, 0.348-1.084 % K, 0.189-2.819 % Ca, 0.762-2.445 % Mg, 11, 14-330.36 ppm Fe, 2.36-4.82 ppm Mn, 4.23-31.49 ppm Zn and 0.43-22.71 ppm Cu. Their leaf nutrient contents were 1.12-2.18 % N, 0.006-0.132 % P, 0.44-2.47 % K, 2.82-6.35 % Ca, 2.97-4.67 % Mg, 25.3-314.8 ppm Fe, 6-67 ppm Mn, 11.0-33.2 ppm Zn and 4.75-91.79 ppm Cu. Findings of selections were compared with those of 'Siirt' Turkish pistachio cultivar.
