Abstract

The present investigation was conducted in the laboratory of Department of Seed Science and Technology, College of Agriculture, Junagadh Agricultural University, Junagadh during 2016-17 with an aim to study the effect of bulb size [B1 (25 + 5 g, small size), B2 (50 + 5 g, medium size) and B3 (75 + 5 g, large size)] and plant spacing [S1 (30 cm x 30 cm), S2 (30 cm x 40 cm), S3 (45 cm x 30 cm), S4 (45 cm x 40 cm), S5 (60 cm x 30 cm) and S6 (60 cm x 40 cm)] on seed parameters of onion cv. Gujarat Junagadh White Onion 3 (GJWO 3). The characters viz., germination percentage, root length (cm), shoot length (cm), root fresh weight (mg), shoot fresh weight (mg), root dry weight (mg), shoot dry weight (mg), vigour index - I (length) and vigour index - II (mass) were recorded from the seeds harvested from different combinations of treatments evaluated in field and analyzed as per the Completely Randomized Design (Factorial). The results showed that significantly the maximum germination percentage, root length, shoot length, root fresh weight, shoot fresh weight, root dry weight, shoot dry weight, vigour index I (length) and vigour index II (mass) were recorded in the seeds harvested from bulb size of 75 + 5 g (B3). The next best treatment with respect to all these traits was bulb size of 50 + 5 g (B2). Seeds harvested from the bulbs space planted at 60 cm x 40 cm (S6) recorded significantly the highest germination percentage, root length, shoot length, root fresh weight, shoot fresh weight, root dry weight, shoot dry weight, vigour index I (length) and vigour index II (mass). The next best plant spacing with respect to all these seed parameters was bulbs planted at (S5) 60 cm x 30 cm. The treatment combination B3 x S6 (bulb size 75 + 5 g planted at the spacing of 60 cm x 40 cm) noted the maximum germination percentage, root length, shoot length, root fresh weight, shoot fresh weight, root dry weight, vigour index I (length) and vigour index II (mass).
