Physical properties of soybean cultivated in NEH region of India

Abstract

This study was conducted to investigate physical properties of soybean cultivated in NEH region of India.  Major, minor and intermediate mean diameters of soybean seeds were 8.88±0.55 mm, 4.68±0.32 mm and 6.46±0.36 mm, respectively.  Geometric mean diameter was 6.45±0.35 mm. Mean roundness of the seeds was 0.66±0.02, while mean sphericity of the seeds in their natural rest position was 0.73±0.02.  Bulk density, true density, porosity, thousand seeds weight and angle of repose were 749.50±1.59 kg/m³, 1171.80±115.02 kg/m³, 34.62±9.00 %, and 177.55±3.04 g and 25.82±1.88 º, respectively.  The coefficient of static friction over aluminum, mild steel, and plywood surfaces were 0.46±0.03, 0.45±0.03 and 0.47±0.02, respectively. Statistical analysis indicated that the indigenous cultivar commonly found in NEH region was significantly difference from the cultivars found in the plains.
