dc.description.abstractABSTRACT The present investigation titled “Effect of cultivars and sowing time on production in pea (Pisum sativum L.) under protected conditions” was carried out at Khaltoo research farm and laboratory of the department of Seed Science and Technology, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2021-2022. The field experiment was laid out in Randomized Block Design (factorial) with three replications while the laboratory studies were done using Completely Randomized Design having four replications. There were nine treatment combinations involving three cultivars i.e., V1 (Pusa Pragati), V2 (Pb-89) and V3 (Azad P-1) and three sowing dates viz., D1 (1st October), D2 (15th October) and D3 (1st November). As regards the cultivars, Pusa Pragati recorded minimum values for days to 50% flowering (72.11) and days to seed harvesting (149.00) and maximum values for pod length (10.46 cm), number of seeds per pod (7.49) which were at par with V2 (7.46), 100 seed weight (20.33 g) which was also at par with V2 (20.03 g), seedling dry weight (40.60 mg) and SV-II (4040.25). PB-89 recorded minimum days to field emergence (8.33), maximum number of pods per plat (18.38), pod yield (72.98 g/plant and 2.85 kg/m2), shelling percentage (55.24), seed yield (17.28 g/plant and 0.240 kg/m2), seedling length (22.67 cm) which was at par with Azad P-1 (22.34), SV-I (2261.64) which was also at par with Azad P-1 (2215.37). Maximum plant height was obtained in Azad P-1 (127.49 cm). Among different dates of sowing, 15th October sowing recorded minimum values for days to seed harvesting (155.44) and maximum values for pod length (9.40 cm), number of pods per plant (18.68), pod yield (71.69 g/plant and 2.79 kg/m2), shelling percentage (50.94), number of seeds per pod (7.39), seed yield (15.81 g/plant and 0.211 kg/m2), 100 seed weight (19.18 g) which was at par with 1st October (19.10 g), seedling length (23.07 cm) which was again at par with 1st October (22.91 cm), seedling dry weight (37.88 mg) at par with 1st October sowing date (36.86 mg), SV-I (2301.23) at par with 1st October (2280.90), SV-II (3778.96) at par with Ist October (3670.83). 1st October sowing recorded minimum values for days to 50% flowering (80.00). The interaction V2D2 (Pb-89 sown on 15th October) showed minimum days to field emergence (7.00), number of pods per plant (18.68), pod yield (102.88 g/plant and 4.01 kg/m2), shelling percentage (60.07), number of seeds per pod (8.43), seed yield (23.68 g/plant and 0.325 kg/m2), 100 seed weight (21.42 g), V3D1 recorded maximum seedling length (24.24 cm) which was statistically at par with V2D2 (23.47 cm) and maximum SV-I (2412.10) which was again at par with V2D2 (2347.25), V1D3 recorded maximum seedling dry weight (42.10 mg) which was statistically at par with V2D2 (41.52 mg), SV-I (2347.25), SV-II (4152.50). Though germination percentage showed non-significant results but maximum of 100% germination was reported in V2D2 and minimum of 98.25% in V3D3. Hence, it was concluded that treatment combination V2D2 (Pb-89 sown on 15th October) can be recommended for quality seed production of garden pea under naturally ventilated polyhouse.en_US
