Description A field experiment was carried out to study the effect of three spacings viz., S1- 30 x
10 cm, S2- 30 x 15 cm and S3- 37.5 x 10 cm and three fertilizer levels viz., F1- 20:50 NP
kg/ha, F2- 31.25:62.50 NP kg/ha and F3- 37.50:75 NP kg/ha on crop growth, seed yield and
quality of green gram cv. DGGV-2. Among the three spacings significantly more number of
branches per plant, pods per plant, pod yield per plant, seeds per pod, seed yield per plant and
seed yield per ha (1167 kg), 100 seed weight, seed germination (91.56 %), seedling vigour
index (3077) were noticed in S2 fallowed by S3, whereas plant height was maximum in S1.
Similar results on seed yield and quality parameters were recorded in F2, whereas plant height
and number of branches per plant were maximum in F3 level. Interaction (S x F) effect was
found non-significant for both crop growth and seed quality parameters but seed yield
components were significantly higher in S2F2 treatment combination.
A laboratory experiment was carried out under ambient condition for eight months to
evaluate storage performance of six varieties viz., V1- LGG-460, V2- SML-668, V3- DGGV-
2, V4- DGGV-4, V5- S-4 and V6- Chinamung with five seed treatments viz., T1- control, T2-
garlic paste @ 5 g/kg, T3- custard kernel powder @ 10 g/kg, T4- castor oil @ 5 ml/kg and T5-
deltamethrin EC @ 0.05%. Among the varieties, LGG- 460 was found to be a good storer by
recording less value for quantitative parameters and less percent decline in qualitative
parameters. Seed treated with castor oil and deltametrin has retained higher seed quality with
less quantitative losses against control during eight months of storage period. Interaction (V x
T) effect was found non-significant for both quantitative and qualitative parameters. In
general, LGG- 460 seeds treated with castor oil retained higher seed quality well above
Minimum Seed Certification Standards with minimum quantitative losses as against untreated
seeds of S-4 variety for eight months period.
