Abstract

Grain yield of directly seeded Peta variety of lowland rice was greatly influenced by now spacing and seeding rates, Spacing the plants at 30 cm. between rows gave 8.86 and 16.40 cav. More per ha. Over per ha. Over those spaced at 40 and 20 cm., respectively. As the seeding rates increased, a corresponding significant in grain yield was obtained. The highest grain yield (70.64 cav. Per ha.) was obtained when Peta was seeded in 30 cm. row at the rate of 30 gantas per ha.

The duration of flowering period was markedly influenced by the seeding rate and row spacing. The plants flowered earlier when seeded at closer with a seed rate of 30 gantas per ha.

Other plant characters associated with grain yield such as panicle length, plant height, and number of bearing and non-bearing culms, and test weight of 1000 seeds were not considerably affected by spacing and seeding rate.
