Abstract

The present investigation was carried out in laboratory of the Department of Seed Science and Technolo-gy, College of Agriculture, Junagadh Agricultural University, Junagadh from the April 2013 to April 2015, wherein two kg of freshly harvested quality seed of soybean cv. Gujarat Junagadh Soybean 3 having high germination percentage and low moisture content (below 8%) was taken for each repetition and for each combination of treat-ments. The treatment consisted of two storage conditions (C) viz., C1 (Ambient temperature) and C2 (Cold storage at 7oC + 2oC), and five seed treatments (S) viz., S1 = Control, S2 = Carbendazim @ 2g/kg seed, S3 = Mancozeb @ 2g/ kg seed, S4 = Neem leaf powder @ 10g/kg seed, and S5 = Neem Oil @ 5 ml/kg seed. The experiment was carried out using Completely Randomized Design (Factorial) repeated three times. After proper mixing or smearing the seeds as per the treatments, seeds were packed in cloth bag and kept in laboratory under two different storage conditions. Observations were recorded at 90 days interval on germination (%), root length (cm), shoot length (cm), seedling dry weight (g), seed vigour index I, seed vigour index II and seed moisture content (%). The results revealed that storage condition (C) and seed treatments (S) exhibited significant differences almost for the all the traits for germination and seedling parameters after 2 years of storage. The results of soybean seed stored in two different storage conditions showed that on an average, the seed stored under cold storage (70C + 20C) noted higher values for all the traits studied except seed moisture content after 2 years of storage. Among the seed treatments, on an average, after 2 years of seed storage, significantly (P<0.05) higher values were recorded by all the seed treatments over the control. However, seed treated with Mancozeb @ 2g/kg of seed recorded the significantly highest germination percentage (71.50 %) and it was at par with Neem leaf powder @ 10 g / kg seed (70.67%) and Carbendazim @ 2g /kg seed (69.67%) after 2 years of storage. The germination percentage noted in control treatment was 33.17 per cent after 2 years of storage. An ISTA standard for germination in soybean is 70 per cent. Most of the interactions effects were found significant (P<0.05) for all the traits studied.
