Effect of zinc supplied from two different sources on the growth, yield and zinc uptake of rice (cv. BRRI dhan49)

The field experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during Aman season of 2014 to study the influence of different levels of zinc applied from two sources on the yield and Zn uptake of BRRI dhan49. The soil was silt loam in texture having pH 6.8, organic matter 2.72%, total N 0.151 %, available P 4.00 mg kg-1, available K 0.08 cmol kg-1, available S 15.9 mg kg-1 and available Zn 0.90 mg kg-1. The experiment was laid out in a randomized complete block design with three replications. There were seven treatments with different rates of Zn viz. T1: Zn0, T2: Zn1 as ZnO, T3: Zn2 as ZnO, T4: Zn3 as ZnO, T5:…
