The Importance of Using Minia Azotin and Some Micronutrients in Improving the Growth and Chemical Constituents of Khaya Senegalensis Seedlings
Year: 2015
Type: article
Abstract: This investigation was carried out during two successive seasons 2012 and 2013 to study the influence of the application of bio-fertilizer (Minia azotin) at zero, one, two and three times, some micronutrents (Zn at 0, 50 and 100 ppm, Mn at 0, 50 and 100 ppm, Zn 50 + Mn 50 ppm and Zn 100 + Mn 100 ppm) and their interaction on plant growth and chemical constituents of Khaya senegalensis seedlings. In regard to bio-fertilizer (Minia azotin) treatments, the data showed that plant growth traits (stem length, stem diameter, leaves fresh and dry weights, stem fresh and dry weights) as well as the three examined elements N, P and K % were augmented due to inoculating Khaya senegalensis seedlings with Minia azotin at all application times (one, two and three) compared to untreated (control). The highest values of these above mentioned parameters were obtained as a result of applying Minia azotin at three times. As for micronutrient treatments, the presented results revealed that Zn or Mn either separating or in mixture increased the growth characters and chemical constituents in comparison with control plants. Spraying the plants with Zn 100 + Mn 100 ppm registered the best results of these parameters of growth and chemical constituents. In this respect to the interaction, the obtained data detected that the most effective treatments were detected due to application of Minia azotin at three times and Zn 100 + Mn 100 ppm concerning stem length, Minia azotin at three times or two times plus Zn 100 + Mn 100 or Zn 50 + Mn 50 ppm concerning N, P and K % . The use of Minia azotin at three times + Zn 50 + Mn 50 ppm gave the heaviest stem fresh and dry weights compared to other combination treatments in the first season.
