“…Considerable accumulation of dry matter in the tuber after linear phase of bulking might be the reason of the higher yield at 90 DAP harvest compared to other days to harvest, caused by significant reductions in the percentage of large tubers and the tuber specific gravity at early and advanced stage of the crop [27]. Similar findings were found by Sharkar et al [28], that the maximum total tuber yield was recorded at 90 DAP. They also stated that 90 DAP harvest could be considered advantageous for total tuber production of potato, since it was found significantly difference to other harvesting times, which was also align with our findings.…”

“…In case of Bari Alu 43 (Atlas) the dry matter gradually increased up to 90 DAP and incase of Bari Alu 45 (Steffi), the dry matter gradually increased up to 80 DAP. According to Solaiman et al [30], dry matter 21.72% was found higher at 110 DAP than it was 16.94% at 80 DAP and again according to Sharkar et al [28] optimum dry matter content 24.07% was also recorded in 90 DAP. These findings were clearly reflected that the dry matter accumulation was increasing with higher harvest days which was similar to our findings in the present study.…”

The experiment was conducted at Breeder Seed Production Centre, Bangladesh Agricultural Research Institute (BARI), Debiganj, Panchagarh during November to February of 2014-2015 to learn about the bulking behavior of promising potato varieties in Bangladesh with the suitable time of harvest for getting desirable yield. The experiment was employed with randomized complete block design (RCBD) with six harvesting time at 10 days interval started from 40 days after planting (DAP) and continued up to 90 DAP. Six promising potato varieties such as Bari Alu 40 (4.45w), Bari Alu 41 (5.183), Bari Alu42 (Agila), Bari Alu 43 (Atlas), Bari Alu 44 (Elgar) and Bari Alu 45 (Steffi) were included in the study. Tuber yield was increased up to 90 DAP for all the varieties. The highest tuber yield (55.86ton/ha) was recorded in Bari Alu 45 (Steffi) and the lowest yield of tuber was observed in Bari Alu 43 (Atlas) at 90 DAP. The tuber yield increase rate of Bari Alu 45 (Steffi), Bari Alu 41 (5.183), Bari Alu 42 (Agila) and Bari Alu 40 (4.45w) were reasonable up to 90 DAP, while the increase rate of Bari Alu 43 (Atlas) was reasonable up to 80 DAP and Bari Alu 44 (Elgar) was up to 70 DAP. Bari Alu 44 (Elgar) may be harvested as early variety among the varieties. The percent dry matter was increased up to 90 DAP for all the varieties. The growth rate of tuber was higher at 60–70 DAP for all the varieties except Bari Alu 41 (5.183). In case of Bari Alu 41 (5.183) tuber growth rate was higher at 70-80 DAP. Finally, our study demonstrated that, the optimal period to harvest potatoes is 90 days after planting (DAP), when the tubers are at their largest size, have the most yield, and have accumulated the maximum dry matter.

“…The result indicated that variety Lady Rosetta could be preferred as suitable variety and 90 DAP harvest could be optimum to get higher DM content. Sharkar et al (2019) also suggested that 90 DAP harvest was suitable for processing considering optimum dry matter content, specific gravity, starch content, processable tuber yield and total tuber yield in the similar growing conditions.…”

The present study was conducted to find out a suitable harvesting date of processing potato varieties (Asterix, Courage and Lady Rosetta) from three different harvest dates [80, 90, and 100 days after planting (DAP) harvest] by chemical maturity monitoring. Eighty DAP harvest resulted the lowest mean total soluble sugar (TSS) (3.77 mg/g FW), reducing sugar (RS) (1.57 mg/g FW), sucrose (2.40 mg g-1 FW), fructose (0.77 mg/g FW) and polyphenol (238.94 μg/g FW) contents in all the varieties and at the same DAP harvest, dry matter (DM) content (21.71%) and chip color index (CCI) (0.67) remained at the lowest. Tubers harvested at 80 DAP produced good quality and acceptable colored processed products as it meets up the required processing quality, but lesser DM content might increase the cost of the product. Optimum DM content (24.07%) with moderate level of different sugar contents and acceptable CCI (1.13 to 1.85, <2.00) was found at 90 DAP harvest. Therefore, 90 DAP harvest could be considered as suitable harvesting date for processing by compromising some quality parameters (TSS, RS, sucrose, fructose and polyphenol contents). Among the varieties, Lady Rosetta and Courage were preferable for producing quality potato products. Highly significant and positive correlation existed between CCI and different chemical parameters. A strong correlation coefficient (r = 0.822**) and good fit (R2 = 0.6755) of the regression equation (CCI = 0.9341RS – 0.4969) between CCI and RS indicated that RS content played the vital role in the browning of the processed potato products.

“…According to Sharkar et al [15], after harvesting, potato tubers were divided into four grades based on their diameter in the centre. Under grade (less than 28 mm), Grade A (28-40 mm), Grade B (41-55 mm), and Over grade (more than 55 mm) were the four grades.…”

Aims: The main aim of this study was to find out the suitable variety having the export potentiality. Study Design: The experiment was laid out in a randomized complete block (RCB) design with the two replications in each location. Place of the Study: The study was conducted in ten different agroecological environments across the country, namely Bogura, Jashore, Munshiganj, Gazipur, Patuakhali, Faridpur, Debiganj, Madaripur, Thakurgaon and Rangpur district of Bangladesh during November 2020 to March 2021. Methodology: Sixty-two released potato varieties and exotic materials were used as planting materials for the experiment. Whole seed tubers of 28–40 mm were planted in the last week of November with a spacing of 60 cm between the rows and 20 cm between the plants. The crops were harvested at full maturity during March. Tuber yield was determined by adding the weights of marketable and unmarketable tubers from the net plot area and converting them to tons per hectare. After that, the tubers were graded in different grades and the dry matter of the potato was analyzed. Results: Considering the results, the location Rangpur, Thakurgaon, Debiganj and Bogura are the most suitable place for export variety cultivation in Bangladesh. The potato variety and genotypes 13.7, BARI Alu-12, BARI Alu-61, BARI Alu-68, BARI Alu-73 and Innovator were found promising for export for their yield, tuber size and dry matter content. Conclusion: The variety having good yield, bigger size and high dry matter could be selected for export from Bangladesh and the better-performed regions can be utilized for export quality potato production in Bangladesh.
