Lentil (Lens culinaris, Medikus) is an important food legume
cultivated in rainfed areas in many countries including India. Field experiment
to investigate the germination potential, seedling vigour and yield of lentil
(Lens culinaris, Medik.) var ‘PL-4’ against three seed rates with hydro-primed,
osmo-primed, sprouted seeds and unprimed seeds under tilled soil situation was
conducted during rabi seasons of 2008-09 and 2009-10. The treatment was laid
out under split-plot design using hydro-primed, osmo-primed with 1% KH2PO4,
sprouted and unprimed seeds in the main plot and three seeding rates of 40, 50
and 60 kg/ha in the sub-plot. Yield attributes were recorded at harvest. Data
were analyzed by OPSTAT software with split plot design, and priming methods in
the main and seed rates in the sub-plots.
The result revealed that the highest germination rate was
reflected with hydropriming which was significantly superior to other priming
methods. The hydro-primed seeds significantly increased the percent germination
(96.13%), nodules/plant (11.05), pods/plant (43.27) and seeds/ pod (1.91) as compared
to rest of the priming methods but sprouted seed indicated better results
statistically at par with hydro and osmo-priming in respect of root length
(18.63 cm) and shoot length (28.63 cm), seedling vigor (4.35). Branches/plant
(13.12) and test weight (2.11 g) showed insignificantly higher values in
osmo-priming. The highest yield was achieved with sprouted seed (844.90 kg/ha)
which was statistically at par with the rest of the treatments except unprimed
seed. All the seed rates indicated no significant differences among them in
respect of germination %, seedling vigor and other growth parameters, seeds/
plant and test weight except nodule count, branches/ plant, pods/plant and grim
yield in which medium seed rate (50 kg/ha) was superior over rest of the seed
rates. Interaction effect indicated that, sprouted seeds with medium seed rate
(50 kg/ha) resulted in a significantly higher yield (856.27 kg/ha). A higher
seed rate resulted in a significant increase in yield for hydro-primed or
osmo-primed (KH2PO4) seeds. Sprouted seed and all priming agents indicated
better yield than unprimed seeds while medium seed rates gave higher grain
yield over lower and higher seed rates. Sprouted seeds with 50 kg/ha seed rate
were optimum in rainfed lentil cultivation under conventional tilled soil
conditions.
