Abstract: The present investigations were carried out at the experimental farm of Department of Floriculture and Landscape Architecture, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan, HP during 2015 and 2016. The experiment was laid out in a Randomized Block Design (factorial) consisting of 48 treatment combinations of four planting dates <em>viz</em>., D₁- mid March, D₂-mid April, D₃-mid May and D₄-mid June and two cultivars namely V₁-Kamini and V₂-Poornima with six mulching materials M­₀­-without mulch, M₁-Black plastic mulch (100 µ),<strong> </strong>M₂-Silver plastic mulch (100 µ),<strong> </strong>M₃­-Transparent plastic mulch (100 µ),<strong> </strong>M₃-Transparent plastic mulch (100 µ),<strong> </strong>M₄­- Pine needle (100 µ) and M₅-Grass (1 inch layer). Among different planting times, D₄ <em>i.e.</em> mid June planting obtained best results for number of seed per flower (179.38), germination per cent (83.92 %), electrical conductivity (0.97 ds/m), seedling dry weight (7.09 mg), seedling vigour index I (763.79), moisture content (7.83 %) and 1000 seed weight (1.94 g). However, seed yield per plant (14.30 g) were recorded to be maximum in mid of March. Among the cultivars, cv. ‘Poornima’ gave best results for number of seed per plant (187.30). However, cv. ‘Kamini’ recorded the best result for seed yield per plant (12.55), electrical conductivity (1.11 ds/m), germination per cent (80.47 %), seedling dry weight (5.11 mg), seedling vigour index I (649.49), moisture content (9.28 %) and 1000 seed weight (1.70 g). Silver plastic obtained best results for number of seed per flower (170.10), seed yield per plant (11.98 g), germination per cent (80.17 %), electrical conductivity (1.26 ds/m), seedling dry weight (4.46 mg), seedling vigour index I (616.78), Moisture content (9.35 %) and 1000 seed weight (1.75 g).
