density is necessary to achieve the production potential of a cultivar in all
crops. To investigate the performance of different cultivars in direct seeded
rice in response to various seeding densities, a field experiment was conducted
at Agronomic Research Area, University of Agriculture, Faisalabad during the kharif 2012. Super basmati (fine rice)
and KSK-133 (coarse rice) were sown using seeding densities of 30, 45,
60 and 75 kg·ha-1. Results indicated that leaf area index and crop growth
rate varied among rice cultivars as well as various seeding densities. The
growth of rice at seeding density of 75 kg·ha-1 was higher than rest of treatments.
The response of rice yield and its components like number of productive
tillers, number of kernels per panicle and 1000-kernal weight differed
significantly under the influence of cultivars and various seeding densities.
Seeding density of 75 kg·ha-1 remained superior for both rice
cultivars regarding final yield. This treatment furnished kernel yields of 3.83
and 5.49 t
