Description |
A field experiment was conducted in boro (spring-summer) 1999-2000,2000-01 and 2001-02 to study the response of promising rice (Ovza sativa L.) hybrids to double transplanting in late sown situation. The results revealed that 'PA 6201 ' rice hybrid with high seedling height in early stage gave highest grain yield (6.36 tonnes/ha) and net returns (Rs 9 973). Adoption of double transplanting using seedlings grown for 30 days in first nursery followed by 20 days in second nursery was beneficial considering easy stand establishment, low weed pressure, high grain yield (6.3 1 tonnes/ha) and net returns (Rs 9 682) compared with the standard practice of single planting (6.03 tonnesiha and Rs 7 726). However, allowing seedlings for 40 or 50 days in the second nursery resulted in low grain yield (5.68 or 5.40 tonnes/ha) and net returns (Rs 7 439 or 6 330).
