Influence of Size Grading on Physiological Parameters in Chickpea Cv. BGD 103

Abstract

The influence of seed size on physiological seed quality characters were evaluated in Chickpea cv.BGD 103 using seeds retained on 6.00 mm, 6.75 mm, 7.00 mm, 7.25 mm, 7.50 mm and 7.75 mm, round aperture metal sieves. On the basis of two years data, the results revealed that the 6.75 mm sieve recorded high seed recovery (96.31 %) than other sieves with better seed quality parameters like germination percentage (96.50 %), 100 seed weight (33.41 g), pure live seed (94.72 %), physical purity (98.15 %) and seedling vigour index (2501). Hence, seeds of chickpea cv. BGD 103 could be size graded with 6.75 mm(R) sieves for more seed recovery with Minimum Seed Certification standard (MSCS) for seed approval by Govt. of India.
