Abstract/ Executive Summary:

Twenty two potato accessions from USA were evaluated for nutrient contents. Two Bangladeshi varieties were also included for comparison. Nutritional analyses were performed in the Department of Agricultural Chemistry, BAU during November, 2014 to April, 2015. Considering macro nutrient content, the highest values of N, P, K and S were found in the accession AC 10062 whereas Ca and Mg contents were found highest in Bangladeshi variety Cardinal and USA accessions AC 10073, respectively. In case of micro nutrient, the maximum amounts of Cu, Mn, B and Zn were observed in accession AC 10110, AC 10069, AC 10073 and AC 10109, respectively. Significant positive correlations were observed between N-P, N-K and K-Mn contents while K-Mg, Mn-B and Cu-B contents were negatively correlated. Considering all the parameters studied, the USA accession AC 10062, AC 10069 and AC 10110 were nutritionally superior to Bangladeshi variety Diamant and Cardinal. The accession AC 10062 was found as the best USA accession to produce nutrient rich potato in Bangladesh.

Program Area: Variety and Species

Commodity: Potato

Objectives:

The experiment was carried out to characterize the USA potato accession in relation to nutrient contents and selecting suitable ones for commercial cultivation under Bangladesh condition.

Methodology:

In order to study nutrient contents, twenty two potato accessions of USA and two varieties from Bangladesh were analyzed. The USA accessions were AC 10016, AC 10062, AC 10063, AC 10064, AC 10068, AC 10069, AC 10072, AC 10073, AC 10074, AC 10076, AC 10077, AC 10078, AC 10081, AC 10097, AC 10109, AC 10110, AC 10112, AC 10120, AC 10122, AC 10123, AC 10125 and AC 10190, along with two varieties Diamant and Cardinal from Bangladesh. Potato tuber samples were collected from Horticulture Farm, Bangladesh Agricultural University, Mymensingh. For chemical analysis, samples were oven dried at 80^oC for 72 hours and then ground. Total N was analyzed using Kjeldahl method. For the determination of other nutrients, the samples were digested by using di-acid mixture (HNO3 : HClO4 = 2:1) as described as Singh et al. (1999). Nutrient contents (P, K, Ca, Mg, S, Cu, Mn, Zn and B) of different potato accessions were determined by standard methods of analysis (Page et al., 1982; Ghosh et al., 1983; Tandon, 1995). The data were analyzed using Complete Randomized Design (CRD) and the pair comparisons were performed by DMRT test at 5% level of probability (Gomez and Gomez, 1984).

Achievement/Findings:

Nutrient contents of different potato accessions of USA and Bangladesh differed significantly. Among the twenty four accessions under trial the accession AC 10062 was superior to other accessions acknowledging nutrient content. Therefore, accession AC 10062 can be suggested to cultivate in Bangladesh to produce nutritionally superior potato.
