BOREN-Project studies on the research and application of Boron fertilizer use with the Agriculture Boron Research and Application Program were initiated within the framework of the cooperation protocol signed with the Ministry of Food, Agriculture and Livestock, General Directorate of Agricultural Research and Policies (TAGEM) on 01.03.2011.
Agricultural Boron Research and Application Projects were carried out over 18 projects focused on region and plants. The plants subject to the experiments include: Sugar Beet (Central Anatolia); Sunflower (Thrace); Apple (Isparta Region); Hazelnut-I (Samsun and Ordu); Hazelnut-II (Giresun-Trabzon); Tea Plant (East Black Sea); Greenhouse Tomatoes (Antalya), Industrial Tomatoes (Bursa, Izmir and Manisa); Wheat-I (Ankara and Eskisehir); Wheat-II (Konya and Karaman); Corn (Adana and Osmaniye); Potatoes (Niğde and Eskisehir), Pistachio (Gaziantep and Şanlıurfa); Vineyard (İzmir, Manisa and Denizli); Cotton-I (Şanlıurfa and Kahramanmaraş); Cotton-II (Adana and Hatay); Carrot (Ankara-Beypazarı) and Olive (İzmir and Muğla).
The main results obtained in each plant species are summarized below:
Sunflower: B deficiency was detected in 16% of the sunflower planted areas in the Thrace Region, and the increase in yield was found to vary between 10 and 20% in the field trials carried out in 16 locations. 0.1 kg B/da is recommended for sunflower in the region.
Sugar Beet: It was found that approximately 40% of 361 soil samples collected from Konya, Karaman, Afyon and Eskişehir regions showed boron deficiency. The problem is mostly seen in Seydişehir and Beyşehir districts of Konya Province. B deficiency was found in 26% of 139 leaf samples collected in the region. A total of 12 trials were conducted over two years. In the trials, yield increases of between 6% and 15% were observed, and most of these increases were found to be significant. In order to increase the yield and sugar rate of sugar beet in the region, it is recommended to apply 0.1 kg/da of boron in areas with boron deficiency.
Hazelnut-I: In the study carried out with hazelnut plant in Ordu and Samsun regions, B deficiency was detected in 65% of the hazelnut growing areas in Ordu and 38% in Samsun. According to the B fertilizer trials, an increase of about 25% in hazelnut yield was observed as the average of the two-year trials. It was determined that boron fertilization increased the hazelnut yield by 10%. As the most appropriate dose on hazelnut yield and efficiency, 3 g B ocak-1 and 300 mg B/L foliar application dose have been recommended.
Hazelnut-II: In the study carried out in the hazelnut growing areas in Giresun and Trabzon regions, 90% of the soils of both regions were determined to be insufficient in soils. In the boron fertilizer trials, an average of 30% increase in hazelnut yield was determined. As the most appropriate dose on hazelnut yield and efficiency, 3 g B pit-1 and 300 mg B/L foliar application dose have been recommended.
Tea Plant: : In the study carried out with the tea plant in the Eastern Black Sea Region, it was determined that the boron suitable for the plant was deficient in 97% of the soil samples taken from the tea plant cultivation areas. In the experiments carried out in the region, the fresh leaf yield was 10-22% in the first year and in the second year. It has been determined that there is an increase of 8-16% per year. For tea plants, application of 300 mg B/L from the leaf and application of 0.5 kg B/da from the soil have been recommended.
Potatoes: In the study carried out on potatoes in Nevşehir and Niğde Region, B deficiency was detected in 20% of the soils. According to field trials, Boron applied from soil and leaves provided yield increases between 3% and 26%, depending on the location, in potato tuber yield. For potatoes, application of 300 mg B/L from the leaf and application of 0.2 kg B/da from the soil have been recommended.
Wheat-I: Boron deficiency was determined in 54% of 256 soil samples collected in Konya and Karaman Regions. Leaf analyzes show that the deficiency is not significant. However, boron application in soil (0.2 kg B/da) increased wheat yield by 12.5% in irrigated conditions and by 21% in dry conditions.
Wheat-II: Boron deficiency was observed in 21% of 350 soil samples collected during the surveys in Ankara and Eskişehir regions. Boron deficiency is around 11% in 180 leaf samples collected.
Tomatoes: Boron was found to be insufficient in 27% of the soil samples taken from the areas where industrial tomatoes produced in Bursa, İzmir and Manisa regions were grown, and yield increases ranging from 20 to 36% were observed with boron fertilization depending on the locations in the trials conducted in these areas. The ideal Boron application dose was determined as 0.1-0.25 kg B/da.
Corn: Boron deficiency was observed in 57% of soil samples taken from corn production areas in Adana and Osmaniye regions. According to the results of the first year, yield increases with application of Boron from soil and leaf varied between 3% and 19% depending on the locations.
Vineyard: 326 soil and 326 leaf samples were collected from orchards in İzmir, Manisa and Denizli provinces where vineyards are grown in their regions. According to the analysis, boron deficiency was observed in 44% of the soils and 16% of the plants in these regions. Among the experimental locations, the yield of fresh grapes increased by 20% with boron fertilization in Menemen, İzmir.
Carrot: Boron deficiency was determined in 17% of the soil samples taken from the areas where carrot cultivation is carried out in the Beypazarı district of Ankara.
