Effects of Seed Weights on Plant Growth and Mineral Nutrition of Wheat and Bean Plants

This study was aimed to investigate the effects of different seed weights on plant growth, mineral nutrition and nutrient uptake of wheat and been plants. Also relations among seed weights and examined parameters were examined. For this purposes, 3 groups of wheat grains having 3.35, 4.05 and 4.98 g 100 seeds -1 and 4 groups of been grains having 30.02, 45.18, 54.01 and 58.6 g 100 seeds -1 were selected. Experiment was set up under greenhouse condition and left for growing during 2 months. After the experimental period, plants were harvested and analyzed for mineral analysis. According to the results it was seen that dry weights of both plants increased with the seed weights. For wheat plants, increasing of seed weights led to increase of plant Fe, Zn and Mn concentrations. Also K, Ca, Mg, Fe, Zn and Mn uptake of plant from the soil increased with increase of 100 seed weights. Similarly, N, Ca, Mg and concentrations of bean and nutrient uptake (K, Ca, Mg, Fe, Cu, Zn and Mn) from the pot increased with the seeds weights. For both plants, while there were not any correlations among seeds weights and seed nutrient concentrations generally, there were some significant correlations among the seeds weights and dry weights, leaf nutrient concentrations and nutrient uptake.

Relations among Boron Status and Some Soil Properties of Isparta Region Apple Orchards

This study was conducted to determine the boron (B) status of apple orchards and examine the relations among B nutrition and some soil properties in Isparta province. For this purpose 250 gardens from the seven districts of the region were determined and soil and leaf samples were collected. In order to determine soil and leaf B status and relations among these some soil properties were determined. Similarly, other leaf nutrient concentrations were analyzed. According to the soil analysis it was seen that most of the soils are B-sufficient. If soil B concentrations were evaluated depending on the district, the lowest soil B (0.26 mg kg -1 ) was measured from the gardens of Senirkent, the highest B concentration (3.44 mg kg -1 ) was determined in Atabey. Looking at the individual districts, all apple orchards in Gonen and Keciborlu have sufficient (0.5-2 mg kg -1 ) soil B. Also in Yalvac, Atabey, Gelendost and Egirdir 71%, 95%, 96% and 97% of the soils had higher B concentration than B deficiency level (0.5 mg kg -1 ). The most soil B deficiency problem was observed in Senirkent and Yalvac. Average soil B levels for Atabey, Egirdir, Gelendost, Gonen, Keciborlu, Senirkent and Yalvac orchards were calculated as 1.32, 0.96, 0.87, 0.67, 0.91, 0.49 and 0.62, mg kg -1 respectively and general average were determined as 0.84 mg kg -1 . Depending on leaf analyze results, it was seen that 94.8% of the trees had sufficient B and only 5.2 percent of trees had B deficiency. According to the results, there is not B deficiency in 85 % of the soils. And this reflects the leaf analysis as well. Although this result, there was not seen any correlation between soil and leaf B concentrations. But, there were negative correlations among available soil B and soil pH and Ca. Positive correlations were determined among soil B concentrations and other micro nutrients. While a negative correlation between leaf B concentration and leaf P was found, there was a positive correlation between B and Mn.

Effect of Different Nitrogen Doses on Plant Growth, Quality Characteristics and Nutrient Concentrations of Lavandin (Lavandula × intermedia Emeric ex Loisel. var. Super A)

Abstract This research was conducted to determine the effect of nitrogen fertilization on the yield, yield components and nutrient concentrations of lavandin (Lavandula×intermedia Emeric ex Loisel. var. Super A). Experiment was designed as randomized block design with three replications. Nitrogen fertilization increased yields and some quality parameters such as plant height, branch height, length of flower, essential oil content and affected essential oil components (such as: linalool, linalyl acetate and camphor). Nitrogen fertilization also led to increase nutrient concentrations, generally. Results obtained from two years of the study showed that the most effective level of N on lavandin yielding and plant nutrient concentrations appeared to be 100 kg n ha-1.
