A pot experiment was carried out with tomato variety BINA Tomato-3 in the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University (BAU), Mymensingh from March to August, 2010 to study the effect of Indole Acetic Acid(IAA) and Boron(B) on the nutrient contents of BINA Tomato-3. There were four doses of IAA viz. 0, 20, 40 and 60 ppm and B viz. 0, 1.5, 2.0 and 2.5 kg ha-1. The experiment was laid out in a Completely Randomized Design (CRD) with 3 replications. The result revealed that nutrient contents of tomato fruits and plants such as N, P, Ca, Mg and B were significantly influenced by the application of IAA and B. The highest N (0.70%), Ca (0.69%), Mg (0.80%) in tomato fruits and highest N (0.40%), Ca (0.93%), Mg (0.90%) in tomato plants were obtained in 60 ppm IAA along with 2.0 kg B ha-1 and the lowest was obtained in the control treatment. In tomato fruits the highest P (0.41%) was found in IAA40B2.0 treatment, while the lowest P (0.18%) was recorded in IAA0B0.0. The lowest B (4.55µgg-1) was recorded in control, while the highest B (15.72µgg-1) was found in IAA20B2.0in tomato fruits. In tomato plants the highest P (0.34%) was recorded in IAA60B1.5 and the lowest P (0.20%) was found in control. The lowest B (4.15µgg-1) was recorded in IAA0B0.0, while the highest B(13.33µgg-1) was found in IAA40B2.0 in tomato plants. The overall results suggest that treatment IAA60B2.0 was the best from other treatments. |
