-61- number/panicle) was obtained from Tsoo application and minimum value (82.9 number/panicle) was obtained from Tsoo. There was signicant effect of H doses and seeding rates, also the interaction between B doses and seeding rates on grain weight per panicle, Grain weight per panicle increasen with increasing H doses, in contrast, decreased with increasing seeding rates. Maximum value (2.92 gr/panicle) was obtained from Ha-axTsoo, minimum value <1.58 gr/panicle) was obtained from HoxTeoo. Rates of steril spikelets increased up to His, then there was no increases further If doses. Maximum rate af steril spikelets (%7.6) was obtained from Hi®, minimum one (%5.4) was obtained from Ho. There was found no significant effect of seeding rates on that character. It was determined that 1000 grain weight and hectolitre weight were effected significantly from H doses. Maximum value of 1000 grain weight <35.8 gr) was obtained from No, minimum one <33.2 gr) was obtained from H3o. Maximum value of hektolitre weight (53.4 hi) was obtained from Hs, minimum value (49.6 hi) was obtained from Hs.o. The effects of seeding rates on these charecters were not found signicantly. Paddy yield was effected significantly from H doses and seeding rates and also their interaction. The yield increased up to“Ssca application, but it was decreased further maximum H dose. In seeding rates, yield increased until T*so, later decreased in higher applications. The highest paddy yield (886.6 kg/da) was obtained from interaction of ISzaxIa&o, the lowest yield (399.0 kg/ da) was obtained from interaction of HoxT^oo. Paddy grain length decreased with increasing H doses. Maximum value (9.62 mm) was obtained at Ho, minimum value (9.32 mm) was obtained at Hso. Seeding rates had no significantly effects on that character. It was seen no effects of H doses and seeding rates on width of paddy grain-60- SUJUUHY This study was conducted to determine optimum seeding rate and nitrogen dose for Rocco rice cultivar which is grown widely in our region. For this purpose, six nitrogen doses < Şo= 0 kg-ff/da, ff*= 6 kg-N/da, »ia= 12 kg-JT/da, Hı©= 1& kg-F/da, N2*= 24 kg-N/da, Hso= 30 kg-H/da) and seven seeding rates < Tsoo= 300 seed/m2, T3bo= 350 seed/m35, T*oo= 400 seed/m2, Taso= 450 seed/m2, Tsoo= 500 seed/m2, Tsso= 550 seed/m2, Tsoo= 600 seed/m2) were applied at experiment area of field crops Department of ç. ü. Agriculture Faculty. A field experiment in split plot design with six different nitrogen doses as main plots and seeding rates as subplots was conducted. The results obtained in research are summarized as follows. Nitrogen doses had significant effect on period of panicle initation. Period of panicle initation increased with increasing nitrogen doses. Maximum period of panicle initation (&&,5 days) was obtained from Hso, minimum one (79.9 days) was obtained from Bo. There was no significant effect of seeding rates It was found significantly effect H doses, seeding rates and interaction between B doses and seeding rates on plant height. The plant night was increased by If doses up to Bs».*, but it was decreased by Nso. The plant height decreased with increasing seeding rates. Maximum plant height (106.8 cm) was obtained from interaction of %z<±xlac.a, minimum plant height (64. 7 cm) was obtained from interaction of BToxTeoo. Hitrogen doses had no significant effect on panicle length. The panicle length decreased with increasing seeding rates. Maximum panicle length (17.1 cm) was at Tsroo, minimum one (15.8 cm) was at Tsoo. Number of grain per panicle increased with increasing N doses. Maximum value (95.5 number/ panicle) was obtained from Bs»o, minumum value (76.5 number/panicle) was obtained from So. Bumber of grain per panicle decreased with increasing seeding rates.

Seeding rates had no significantly effects on that character. It was seen no effects of H doses and seeding rates on width of paddy grain-62- Paddy grain thickness decreased with increasing N doses up to Bt©. There were no significantly differences from Fıs to Hao Ratio of paddy grain lengh/width was not effected from K doses. In seeding rates applications, maximum ratio (2.84) was obtained from Ts.bo, and minimum ratio (2.73) was obtained from T*so Hulled grain sizes were not effected by H doses and seeding rates. According to results of the analysis of correlation, there were positive and significantly relations paddy yield with period of panicle initation, plant height, panicle lengh. number of grain per panicle, weight of grain per panicle, rate of steril spiielets. However, there were negative relations paddy yield with 1000 grain weight, hectolitre and sizes of grain.
