Some physical properties of mash bean (Phaseolus aureus L.) seeds cultivated in Turkey

Bu çalışma Maş fasulyesi tohumlarının fiziksel özelliklerinin belirlenmesi için yapılmıştır. Dört nem seviyesinde(% 6.66, % 11.00, % 15.24 ve % 18.59) uzunluk, genişlik, kalınlık, ağırlık, geometrik ortalama çap, küresellik, hacim, bin tane ağırlığı, hacim ağırlığı, son hız, projeksiyon alanı ve parazite değerleri saptanmıştır. Ayrıca çelik ve galvanizli sac levhalarda statik sürtünme katsayısı belirlenmiştir. Nem seviyelerine bağlı olarak, uzunluk, genişlik, kalınlık, ağırlık, geometrik ortalama çap, küresellik, hacim, bin tane ağırlığı, hacim ağırlığı, son hız, projeksiyon alanı ve parazite değerleri sırasıyla 4.45-4.95 mm, 3.84-4.00 mm, 3.81-4.08 mm, 0.048-0.070 g, 4.02-4.30 mm, 0.906-0.870, 30.37-34.95 mm3, 49.2-60.1 g, 771.3-679.1 kg $m^{-3}$ ,6.22-6.54 $ms^{-1}$, 0.140-0.213 cm2 ve %35.08- 47.1 olarak bulunmuştur. Statik sürtünme katsayısı değerlen ise galvanizli ve çelik sac levhalarda sırasıyla 0.270 ile 0.322 ve 0.302 ile 0.367 arasında, nem seviyesine bağlı olarak artmıştır.

Türkiye' de tarımı yapılan Maş fasulyesi (Phaseolus aureus L.) tohumlarını bazı fiziksel özellikleri

The mash bean (Phaseolus aureus L.) seeds were analyzed for physical properties. Physical properties such as length, width, thickness, weight, geometric mean diameter, sphericity, volume, thousand seed weight, bulk density, terminal velocity, projected area and porosity were measured at four moisture content levels (6.66 %, 11.00 %, 15.24 % and 18.59 %). Also the coefficient of static friction on iron sheet and galvanized iron sheet were determined. The values of length, width, thickness, mass, geometric mean diameter, sphericity, volume, 1000 seed weight, bulk density, terminal velocity, projected area and porosity were found as 4.45-4.95 mm, 3.84-4.00 mm, 3.81-4.08 mm, 0.048-0.070 g, 4.02-4.30 mm, 0.906-0.870, 30.37-34.95 mm3, 49.2-60.1 g, 771.3-679.1 kg $m^{-3}$ ,6.22-6.54 $ms^{-1}$, 0.140-0.213 cm2 and 35.08- 47.1%, respectively. The coefficient of static friction increased from 0.270 to 0.322 and 0.302 to 0.367 for galvanized iron sheet and iron sheet respectively.
