Abstract
An investigation entitled “Effect of seed rates on growth, yield and
seed quality of wheat (Triticum aestivum L) varieties was carried out
during rabi season of 2006-07 at Plant Breeding Research Area of CCS
Haryana Agricultural University, Hisar. 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.
