Effects of High Boron Containing Irrigation Waters on Plant Characteristics of Basil (Ocimum Basilicum L.)
Despite ever increasing demands, water resources are both rapidly depleting and their qualities are spoiled up continuously. The ratio of fresh water used in agriculture is decreasing in each day against the increasing demands of the other sectors. For a sustainable agricultural production, low quality waters should be considered to be used in agricultural irrigations. Turkey is highly rich in boron reservoirs. Ground and surface water resources around these reservoirs are contaminated with boron compounds. Use of these sources is a highly significant issue for efficient use of limited water resources. The present study was conducted to investigate the effects of boron-containing irrigation waters plant characteristics of basil. Irrigation waters containing 0, 1, 2, 4 and 8 ppm boron were used in experiments and two harvests were taken. In the first harvest, plant fresh weights varied between 44-89.5 g/pot and plant heights varied between 32.5-44 cm. In the second harvest, plant fresh weights varied between 43-59 g/pot and plant heights between 31.8-35.5 cm. Differences in soil EC, pH, ESP, Na, Ca, Mg, K, B, HCO3, Cl and SO4 contents and plant Na, Ca, Mg, K, B, N, P, K and Cl contents were found to be significant at 5% significance level.
