Effect of nursery seeding density on seedling vigour and yield of summer rice (Oryza sativa) under varying seedling rates

A field experiment was conducted at Chiplima, Sambalpur, Orissa, to find ou t the affect of nursery seeding density on seedling vigour and yield of sum mer rice (Oryza sativa L.) under varying seedling rates. The seedlings beca me taller, thinner and lighter with less leaf and root growth due to increa se in the nursery seeding density. Seedling damage at uprooting, pulling ti me, weed density in the nursery and cost of raising seedling for unit area transplanting became less under higher nursery seeding density. Growth and yield-attributing characters and yield of the crops did not vary significan tly due to difference In the nursery seeding density. Two seedlings/hill we re optimum for getting maximum yields of summer lice.
