Out of 20 countries in different parts of the world where groundwater arsenic contaminations and human suffering have been reported so far, the magnitude is considered to be the maximum in Bangladesh (Sanyal, 2005). Rising arsenic concentrations in groundwater are dangerous for plants, animals, and human’s health (Mirza et al., 2014). Arsenic accumulation by plants and its translocation to the edible or commercial parts were observed to vary with crops and even among the varieties of the potato crop (Kundu and Pal, 2009; Kundu et al., 2010). Arsenic in plant system accumulats mainly in the root system and to a lesser degree in the above ground organs. It causes physiological changes (Wells and Gilmor, 1997) and reduction of the crop productivity. Arsenic is known to disturb uptake and transport of essential mineral nutrient...

However, the phenomenon, "resistant starch (RS)" is the most crucial for our health and body against diseases. From these perspectives, this study was conducted to evaluate the most precise characteristics of RS from which we can get more and more benefits to lead a better life from potato. The interest of RS of potato varied from men to men and the intensity of taking the RS depends on the amount of starch intake. It can regulate the insulin and blood sugar. The cooking procedures and the cooling techniques may vary the amount of starch of potato which is indigestible in nature. After cooking, the cooling increases the percent of RS of potato. Finally, it may be said that the RS could change our health into a good sign as healthy men.

Methods: The experiment comprised of four different doses of K viz., 0 kg K ha-1 , 100 kg K ha-1 , 125 kg K ha-1 , 150 kg K ha-1 and four different types of mulch materials viz., soil mulch, rice straw, water hyacinth and saw dust. The experiment was laid out in a splitplot design with 3 replications. Statistical analysis done by using MSTAT-C program and mean differences among the treatments were compared by Least Significant Difference (LSD) at 5% level of significance. Results: Maximum large sized tubers were produced by 150 kg K ha-1 with rice straw mulch. Application of 125 kg K ha-1 with rice straw produced maximum seed potato and tuber for French fry. Without K and soil mulch produced highest tuber for chips (% by t ha-1). Conclusions: Application of 125 kg K ha-1 with rice straw mulch seems to be more suitable for getting higher seed potato (% by number and % by weight) and French fry for BARI (Bangladesh Agricultural Research Institute) TPS-I.

The yield was negatively affected by the As contamination and decreased with the increasing As levels in the soil, but remained statistically similar up to 25 mg kg-1 soil of As and thereafter drastically decreased with the increasing As levels. The yield reduction (%) and accumulation of As in the tuber peels and flesh increased with the increasing As levels. Among the fourteen potato varieties, 'Felsina' had the maximum yield and showed the lowest percentage of yield reduction; 'Jam alu' and 'Cardinal' accumulated the least amount of As in their peels and flesh, respectively. Among the treatment combinations, 'Felsina' cultivated in an As-free soil had the highest yield/plant (454.8 g fresh weight). 'Laura' grown in 25 mg kg-1 soil of As showed the lowest yield reduction (%). Although 'Jam alu' and 'Cardinal' produced a slightly lower yield compared to some other varieties, these two varieties accumulated the least amount of As, both in the peels and flesh, when grown in 25 mg kg-1 soil of As.

Potato variety and time of harvest had significant effect on nutritional aspects. Reducing sugar, total sugar increased with advancing storage period, whereas specific gravity, non-reducing sugar and starch content decreased with increasing storage period. Among the varieties HPS 364/67 was the best in respect of nutritional aspects. At harvest and 100 days after storage, the highest total sugar (0.61% and 0.82%) was observed from Lady Rosetta and harvest at 110 days after planting, while the lowest total sugar from HPS-364/67 and harvest at 80 days after planting. The results revealed that HPS 364/67 showed superior nutritional quality than other varieties when harvested at 100 days after planting.

Comparative account of some processing traits of three local varieties of potato (viz., 'Fata Pakri', 'Sada Pakri' and 'Rumana)' harvested at 80, 90, 100 and 110 days after planting with those of True Potato Seed variety 'BARI TPS-I' is given in this study tuber samples were harvested after 10-days of tuber skin-curing in the soil. Yield increased significantly up to the last date of harvest. Mature tubers exhibited significantly higher dry matter and specific gravity compared to immature ones. Tuber color was also significantly affected by time of harvest irrespective of varieties. The 'BARI TPS-I' gave highest tuber yield. 'Fata pakri' exhibited highest specific gravity and dry matter content. On basis of flesh color, 'BARI TPS-I', 'Fata pakri' and 'Sadapakri' were found suitable for chips. Bangladeshi potato farmers and processors will get benefited from the information generated regarding the appropriate harvesting time of local potatoes for processing industries.

BARI mung-4). The experiment comprised with two factors viz. Intra-row spacing and Time of weeding. Four row spacing (S1= 15 cm, S2= 20 cm, S3= 25 cm and S4= 30 cm) and four weeding treatments (W0= No weeding, W1= Weeding at 15 days after sowing (DAS), W2 = Weeding at 15 and 30 days after sowing (DAS), and W3 = Weeding at 15, 30 and 45 days after sowing (DAS) were used. There were sixteen treatment combinations under the present study. Results showed that the highest plant height (60.26 cm) was achieved by 15 cm row spacing with three times of weeding. The highest number of leaves plant -1 (11.08) and dry weight plant -1 (15.63 g) were gained by 30 cm row spacing with three times of weeding. With the treatment combination of 25 cm row spacing with two times of weeding showed very close to the combination of 30 cm row spacing with three times of weeding. Hence, the field performance from 25 cm row spacing with two times of weeding and 30 cm row spacing with three times of weeding were significantly similar; so, from economic point of view, 25 cm row spacing followed by two times of weeding was the best treatment combination.

The experiment comprised of four different size of seed tubers, viz., 28-<45 mm, 20-<28 mm, 10-<20 mm and <10 mm and four harvesting time, viz., 70 days after planting (DAP ), 80 DAP , 90 DAP and 100 DAP . The experiment was laid out in randomized complete block design factorial with three replications. The growth parameters such as stems hill -1 , leaves hill -1 , tuber yield plot -1 , marketable yield plot -1 and tuber yield ha -1 were significantly influenced by the seed tuber size and harvesting time. Results revealed that in general, plant height, stems hill -1 increased with increasing seed tuber size but yield attributes and yield increased with 28-<45 mm tuber size. The highest tuber yield hectare was recorded on the tuber size of 28-<45 mm due to increase of tubers hill -1 and tuber yield plot -1 . In contrast, the lowest tuber yield ha -1 was recorded in the smaller seed tuber of <10 mm. Results showed that stems and leaves hill -1 and tubers hill -1 , single tuber weight and tuber weight plot -1 increased with increasing time of harvest upto 90 DAP . The highest number of stems and leaves hill -1 , tubers hill -1 , single tuber weight and tuber weight plot -1 were observed in the harvesting time 90 DAP and the lowest in harvesting time 70 DAP . However, the highest gross tuber yield ha -1 was observed in the harvesting time 90 DAP and the lowest was recorded in 70 DAP . For combined effect of seed tuber size and harvesting time, the highest gross tuber yield was observed in the treatment combination of 20-<28 mm seed tuber with the harvesting time of 90 DAP which was economically adventitious.

Out of 20 countries in different parts of the world where groundwater arsenic contaminations and human suffering have been reported so far, the magnitude is considered to be the maximum in Bangladesh (Sanyal, 2005). Rising arsenic concentrations in groundwater are dangerous for plants, animals, and human’s health (Mirza et al., 2014). Arsenic accumulation by plants and its translocation to the edible or commercial parts were observed to vary with crops and even among the varieties of the potato crop (Kundu and Pal, 2009; Kundu et al., 2010). Arsenic in plant system accumulats mainly in the root system and to a lesser degree in the above ground organs. It causes physiological changes (Wells and Gilmor, 1997) and reduction of the crop productivity. Arsenic is known to disturb uptake and transport of essential mineral nutrient...

In Bangladesh, the quality of aromatic rice is much inferior than those of other rice growing countries because of lack of improved variety and judicious agronomic management. Selection of appropriate variety and supplementation zinc (Zn) and 2-acetyl-1-pyrroline (2-AP) can improve the aroma. The present study exhibited the effects of 2-AP and Zn supplementation on yield and quality of aromatic rice. Two well-known aromatic cultivars, BRRI dhan80 and BRRI dhan34, were cultured separately in pot supplemented with 2-AP and Zn. The results showed that supplementation of 2-AP and /or Zn along with conventional practices had significant effects on organoleptic and some quality parameters studied in this study. The concentration of 2AP and Zn in rice grain increased with increasing their application rate. Additionally, grain 2-AP concentrations were significantly and positively correlate...
RESISTANT STARCH A NEW WEAPON AGAINST DISEASE FIGHTING OF POTATO EATER: A FOCUSED REVIEW, 2016

However, the phenomenon, "resistant starch (RS)" is the most crucial for our health and body against diseases. From these perspectives, this study was conducted to evaluate the most precise characteristics of RS from which we can get more and more benefits to lead a better life from potato. The interest of RS of potato varied from men to men and the intensity of taking the RS depends on the amount of starch intake. It can regulate the insulin and blood sugar. The cooking procedures and the cooling techniques may vary the amount of starch of potato which is indigestible in nature. After cooking, the cooling increases the percent of RS of potato. Finally, it may be said that the RS could change our health into a good sign as healthy men.

Methods: The experiment comprised of four different doses of K viz., 0 kg K ha-1 , 100 kg K ha-1 , 125 kg K ha-1 , 150 kg K ha-1 and four different types of mulch materials viz., soil mulch, rice straw, water hyacinth and saw dust. The experiment was laid out in a splitplot design with 3 replications. Statistical analysis done by using MSTAT-C program and mean differences among the treatments were compared by Least Significant Difference (LSD) at 5% level of significance. Results: Maximum large sized tubers were produced by 150 kg K ha-1 with rice straw mulch. Application of 125 kg K ha-1 with rice straw produced maximum seed potato and tuber for French fry. Without K and soil mulch produced highest tuber for chips (% by t ha-1). Conclusions: Application of 125 kg K ha-1 with rice straw mulch seems to be more suitable for getting higher seed potato (% by number and % by weight) and French fry for BARI (Bangladesh Agricultural Research Institute) TPS-I.

The yield was negatively affected by the As contamination and decreased with the increasing As levels in the soil, but remained statistically similar up to 25 mg kg-1 soil of As and thereafter drastically decreased with the increasing As levels. The yield reduction (%) and accumulation of As in the tuber peels and flesh increased with the increasing As levels. Among the fourteen potato varieties, 'Felsina' had the maximum yield and showed the lowest percentage of yield reduction; 'Jam alu' and 'Cardinal' accumulated the least amount of As in their peels and flesh, respectively. Among the treatment combinations, 'Felsina' cultivated in an As-free soil had the highest yield/plant (454.8 g fresh weight). 'Laura' grown in 25 mg kg-1 soil of As showed the lowest yield reduction (%). Although 'Jam alu' and 'Cardinal' produced a slightly lower yield compared to some other varieties, these two varieties accumulated the least amount of As, both in the peels and flesh, when grown in 25 mg kg-1 soil of As.

Potato variety and time of harvest had significant effect on nutritional aspects. Reducing sugar, total sugar increased with advancing storage period, whereas specific gravity, non-reducing sugar and starch content decreased with increasing storage period. Among the varieties HPS 364/67 was the best in respect of nutritional aspects. At harvest and 100 days after storage, the highest total sugar (0.61% and 0.82%) was observed from Lady Rosetta and harvest at 110 days after planting, while the lowest total sugar from HPS-364/67 and harvest at 80 days after planting. The results revealed that HPS 364/67 showed superior nutritional quality than other varieties when harvested at 100 days after planting.

Comparative account of some processing traits of three local varieties of potato (viz., 'Fata Pakri', 'Sada Pakri' and 'Rumana)' harvested at 80, 90, 100 and 110 days after planting with those of True Potato Seed variety 'BARI TPS-I' is given in this study tuber samples were harvested after 10-days of tuber skin-curing in the soil. Yield increased significantly up to the last date of harvest. Mature tubers exhibited significantly higher dry matter and specific gravity compared to immature ones. Tuber color was also significantly affected by time of harvest irrespective of varieties. The 'BARI TPS-I' gave highest tuber yield. 'Fata pakri' exhibited highest specific gravity and dry matter content. On basis of flesh color, 'BARI TPS-I', 'Fata pakri' and 'Sadapakri' were found suitable for chips. Bangladeshi potato farmers and processors will get benefited from the information generated regarding the appropriate harvesting time of local potatoes for processing industries.

BARI mung-4). The experiment comprised with two factors viz. Intra-row spacing and Time of weeding. Four row spacing (S1= 15 cm, S2= 20 cm, S3= 25 cm and S4= 30 cm) and four weeding treatments (W0= No weeding, W1= Weeding at 15 days after sowing (DAS), W2 = Weeding at 15 and 30 days after sowing (DAS), and W3 = Weeding at 15, 30 and 45 days after sowing (DAS) were used. There were sixteen treatment combinations under the present study. Results showed that the highest plant height (60.26 cm) was achieved by 15 cm row spacing with three times of weeding. The highest number of leaves plant -1 (11.08) and dry weight plant -1 (15.63 g) were gained by 30 cm row spacing with three times of weeding. With the treatment combination of 25 cm row spacing with two times of weeding showed very close to the combination of 30 cm row spacing with three times of weeding. Hence, the field performance from 25 cm row spacing with two times of weeding and 30 cm row spacing with three times of weeding were significantly similar; so, from economic point of view, 25 cm row spacing followed by two times of weeding was the best treatment combination.

The experiment comprised of four different size of seed tubers, viz., 28-<45 mm, 20-<28 mm, 10-<20 mm and <10 mm and four harvesting time, viz., 70 days after planting (DAP ), 80 DAP , 90 DAP and 100 DAP . The experiment was laid out in randomized complete block design factorial with three replications. The growth parameters such as stems hill -1 , leaves hill -1 , tuber yield plot -1 , marketable yield plot -1 and tuber yield ha -1 were significantly influenced by the seed tuber size and harvesting time. Results revealed that in general, plant height, stems hill -1 increased with increasing seed tuber size but yield attributes and yield increased with 28-<45 mm tuber size. The highest tuber yield hectare was recorded on the tuber size of 28-<45 mm due to increase of tubers hill -1 and tuber yield plot -1 . In contrast, the lowest tuber yield ha -1 was recorded in the smaller seed tuber of <10 mm. Results showed that stems and leaves hill -1 and tubers hill -1 , single tuber weight and tuber weight plot -1 increased with increasing time of harvest upto 90 DAP . The highest number of stems and leaves hill -1 , tubers hill -1 , single tuber weight and tuber weight plot -1 were observed in the harvesting time 90 DAP and the lowest in harvesting time 70 DAP . However, the highest gross tuber yield ha -1 was observed in the harvesting time 90 DAP and the lowest was recorded in 70 DAP . For combined effect of seed tuber size and harvesting time, the highest gross tuber yield was observed in the treatment combination of 20-<28 mm seed tuber with the harvesting time of 90 DAP which was economically adventitious.
