ABSTRACT
The present investigations titled “Seed coating studies in pea (Pisum sativum L.)” were carried out using cv. “Pb-89”. The field experiment was laid out in Randomized Block Design at Pandah Research Farm and laboratory studies were conducted in Completely Randomized Design in the Department of Seed Science and Technology, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2018-19. There were seven treatments viz., T1 (seed coating with Rhizobium @ 30 g kg-1 seed), T2 (seed coating with PSB @ 30 ml kg-1 seed), T3 (seed coating with Rhizobium @ 30 g + PSB @ 30 ml kg-1 seed), T4 (seed coating with FeSO4 @ 3 g kg-1 seed), T5 (seed coating with ZnSO4 @ 3 g kg-1 seed), T6 (seed coating with carbendazim @ 2.5 g kg-1 seed) and T7 (control). Foliar sprays of ZnSO4 + FeSO4 @ 0.3 per cent each were given at 50 per cent flowering and 15 days after the first spray in all treatments except control. It was concluded that the treatment T3 influenced nearly all the parameters resulting in maximum field emergence (92.67 %), plant height (91.03 cm), pods plant-1 (27.07), pod length (9.81 cm), seeds pod-1 (7.93), seed yield (13.98 g plant-1, 1.2 kg plot-1 and 21.33 q ha-1), 100 seed weight (17.11 g), germination (96 %), seedling length (19.29 cm), seedling dry weight (34.80 mg), SVI-I (1851.62), SVI-II (3341.38), lowest EC (16.75 μS cm-1), highest germination in accelerated ageing test and in cold test (77.75 % and 80 %, respectively) and maximum B: C ratio (2.00: 1). Therefore, treatment T3 can be suggested for pea seed production after multi-location testing for higher yield of quality seed under mid-hill conditions of Himachal Pradesh.
