Research Article Impact of different seeding densities onyield of direct seeded fine rice

A field experiment was conducted to evalute effect of four different seeding densities viz: 22.5 Kg ha 1 , 30 Kg ha -1 , 37.5 Kg ha -1 and 45 Kg ha -1 on the yield and yield components of fine rice (cv. Super Basmati) under direct seeded conditions at farmers field of Adaptive Research Station, Sialkot during the kharif season 2010-2012 with randomized complete block design. The results revealed that see d rate 37.5 Kg ha -1 produced maximum yield during all the three years. The data of number of productive tillers m -2 was found significantly different during 2 nd and 3 rd years but found nonsignificant during 1 st year. The maximum number of productive tillers m -2 were produced by seed rate 37.5 Kg ha -1 during 2 nd and 3 rd year. The data of plant height showed gradual increase in plant height with the increase of seed rate but it only significantly differed during 1 st year. These results showed that 37.5 Kg ha -1 seed rate in case of direct seeded fine rice performed better than low and high seed rates.
