Dried turmeric rhizomes are generally polished to remove the outer dirty skins, roots and soil, and to transform them to relatively smooth, bright and yellowish rhizomes. In farm level, turmeric polishing is carried out manually following conventional methods, which are slow, tedious and labor-intensive operation. To overcome these problems, a medium-size turmeric polisher was designed and fabricated in Farm Machinery and Postharvest Process Engineering (FMPE) Division of Bangladesh Agricultural Research Institute (BARI) during 2013–14. Length, width and height of the polisher were 1040 mm, 850 mm and 1450 mm, respectively. Weight of the turmeric polisher was 90 kg. A 0.37-kW single-phase induction-type electric motor was used as the source of power for operating the polisher. The polisher was tested in FMPE Division, Regional Spices Research Station (RSRS), Magura and Hill Agricultural Research Station (HARS), Khagrachari. The polisher took 25 minutes to polish a batch of 30 kg dried turmeric. The price of the polisher was Tk 30000. The average cost of polishing by the polisher was Tk 1.42 per kilogram turmeric against the hand beating polishing cost of Tk 5.12 per kilogram. The polisher can save 81% time and 78% cost of polishing than that of hand beating method. Payback period of the polisher is 97 hours. Therefore, the polisher can be recommended for turmeric polishing in Bangladesh as well as for other turmeric growing countries.J. Bangladesh Agril. Univ. 16(2): 303-308, August 2018

In Bangladesh groundnut shelling is done manually which is laborious, time consuming and costly. Shelling of groundnut pod with the help of mechanical power can be a probable solution of this problem. A power groundnut sheller was designed and fabricated in Farm Machinery and Postharvest Process Engineering (FMPE) Division, Bangladesh Agricultural Research Institute (BARI), Gazipur during 2011-13. The sheller was made of Mild Steel (MS) angle bar, MS flat bar, MS rod, MS sheet, MS sieve, rubber pad etc. The shelling capacities of power groundnut sheller were 110 and 115 kg/h for Dhaka-1 and BARI Badam-8, respectively. Average breakage of groundnut kernel was 2% at 7.5% moisture content (wb). The maximum and minimum unshelled pods were about12.4% and 9.18% for Dhaka -1 and BARI Badam-8, respectively. The shelling efficiency of the power groundnut sheller for Dhaka-1 and BARI Badam-8 were 86.6 and 88.82% respectively at 11.5% moisture content (wb). Winnowing efficiency was found to be 99% in the power groundnut sheller. The use of power groundnut sheller can reduce the cost of shelling by 76% over the manual groundnut sheller. This power groundnut sheller is recommended for shelling of groundnut at farm level and small industry level in Bangladesh.Bangladesh J. Agril. Res. 43(4): 631-645, December 2018

Eight heat tolerant CIP (International Potato Centre) potato genotypes along with BARI (Bangladesh Agricultural Research Institute) Alu-7 (Diamant) and one local variety (Dohazari Sada) were evaluated at Agricultural Research Station, Pahartali, Chittagong during 2011-12 to identify heat tolerant genotypes from varieties and CIP clones of potato. Diamant and Dohazari Sada and all the heat tolerant CIP genotypes were found to grow well up to 60 DAP (days after planting) against heat having healthy plants and no senescence was noticed. After that 61-100% plants died due to high temperature (29.8oC) depending on the genotypes. Genotype CIP 139 gave the highest yield (14.18 t/ha) and was comparatively less affected by heat than the other genotypes. The high dry matter (22.43 %) accumulated in the local variety Dohazari Sada. DOI: http://dx.doi.org/10.3329/agric.v12i1.19580 The Agriculturists 2014; 12(1) 50-55

A preliminary investigation was carried out under the AEZ- 29 at the Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI), Pahartali, Chittagong during December 2010 to May 2012 to evaluate two dragon fruit genotypes. The longer plant (272.13 cm) was recorded in HUP 002 while it was 263.34 cm in HUP 001 after one and half year of planting. Flower bud emergence took place after 17 months (on 9 May, 2012) in HUP 001, while it commenced in HUP 002 after 15 months (on 22 March, 2012). Flower bud required 28 days bloom from emergence and the fruit matured after 33 days from anthesis in HUP 001, while that required 35 days for HUP 002 and fruits become matured after 32 days from anthesis. Larger number (8) of flowers per plant was observed in HUP 002 while the lower was noted in HUP 001(6). Numerous anthers were observed below the stigma with attractive white petals in both the varieties. The fruit weights ranged from 200 -375 in HUP 002 but 150-200g in HUP 001. The edible portions were 91.0 and 92.0 with 12.0 and 11.4 % TSS in HUP 001 and HUP 002, respectively. Fruit pulp colour was white in HUP 001 while red in HUP 002.

A study on nutrient uptake by different legume crops was carried out at two locations–one at Bangladesh Agricultural University farm Mymensingh and another at Regional Agricultural Research Station of Bangladesh Agricultural Research Institute, Jamalpur. The objective was to find out the optimum concentrations of different nutrient elements and its uptake by legume crops in a Wheat-Legume-T. Aman cropping pattern. The uptake of different elements was markedly varied by legume crops at both the locations in two consecutive years of the study. It was also noticed that cowpea removed the highest quantity of nutrient elements from the soils in the treated plots compared to mungbean and blackgram. Besides, stover received the maximum contents of potassium followed by nitrogen, phosphorus, and sulphur which was significantly different over legume seeds. Keywords: Nutrient uptake; legume crops.
