The experiment was laid down in split–plot design keeping four varieties viz., PBW-343, WH-711, WH- 283 and WH-542 in main-plots and four seed rates, 87.5, 100, 112.5 and 125 kg ha-1 with three replications. The plant population was observed higher in variety WH-542, followed by PBW-343, WH-711 and WH-283. Growth parameters viz. dry matter accumulation, and number of tillers per meter row length were higher in variety PBW-343. But plant height xix was significantly more in variety WH-283, than rest of the varieties. Leaf area index did not vary due to varieties. All the yield attributes were better in variety PBW-343, except the tests weight. Grain yield was highest in variety PBW-343 and lowest in WH-283. Straw yield was highest in WH-283 followed by PBW-343, WH-542 and WH-711. Harvest index was better in variety WH-711. Germination percentage was significantly different due to varieties, but not due to seed rates. Seedling length, seedling dry weight, vigour index-I and vigour index-II were improved at lower seed rate of 87.5 kg ha-1, in all varieties. Accelerated aging, electrical conductivity and protein content were significantly affected by the varieties while seed rate affected these parameters nonsignificantly. Net return and benefit: cost ratio was highest at the seed rate of 100 kg ha-1 for variety WH-542, at 112.5 kg ha-1 for PBW-343 and at 125 kg ha-1 for varieties WH-711 and WH-283.enPlanting, Strawberry (plant), Micropropagation, Irrigation, Regeneration, Biological phenomena, Biological development, Tissue culture, Planting equipment, Vegetative propagationThesis
