| dc.description.abstract | A field experiment was conducted at the field of Soil Resource Development Institute (SRDI), Sylhet during the period from October 2012 to March 2013 with a view to evaluate the effect of different rates of lime application on soil nutrients and tuber yield of potato. The experiment consisted of four treatments viz. no lime application (control), 0.988 t lime ha¹, 1.976 t lime ha and 2.904 t lime ha. Liming was done with dolomitic limestone (CaCO3.MgCO3). The experiment was laid out in a randomized complete block design with four replications. Yield and yield components of potato were recorded. The pre- and post- harvest soils were analyzed for pH, total N, exchangeable K, available P. S. Ca and Mg contents. The resuns indicated that liming had significant influence on yield of potato tuber. The days required for 80% emergence, foliage coverage, plant height, root length, number of tubers hill, weight of tubers hill and yield of tuber (t ha") were the highest when lime was added at 0.988 t ha. The highest yield of tuber was recorded 19,09 t ha due to application of 0.988 t lime ha and the lowest yield was found 14.38 t ha' in control treatment. Pre- and post-harvest soils analyses indicated that the application of different rates of lime to soil progressively increased soil pH and increased total N, availability of P. S. Ca and Mg in soils. The exchangeable K tended to decrease with increasing level of lime application. | en_US |
