Abstract

To evaluate the effect of PLANTING DATE on dry weight and physiological characteristics of RICE cultivars (Oryza sativa L.) in direct Seeding, Four seeding date as 30 April and 10, 20, 30 May and three cultivars as Hashmi, Tarom and Elpaso were arranged in a split plot design as base of RCBD with four replications. Seeding dates and cultivars were set as Main and sub plots, respctvely. The results showed a significant effect of PLANTING DATE traits days to tillering period, growth period, leaf chlorophyll content, seed number hollow, grain 1000 weight, grain length, yield and HARVEST INDEX found.The first seeding date 36.75 days highest days to tillering and 110.5 was the highest growth period. The second seeding date with 38.16 mg g fresh weight to the highest leaf chlorophyll won. Of all the traits of the figure mentioned was significant. Elpaso cultivar highest with 32.69 per day for tillering and 113.8 days, the highest growth period won. Hashemi cultivar 39.69 mg g fresh weight had the highest leaf chlorophyll content. Interactions between seeding date and cultivar on seed traits hollow, grain 1000 weight, grain length, yield and HARVEST INDEX was significant. Elpaso cultivar in the second seeding date 5582, the highest number of hollow seeds. Hashemi cultivar seeding date the third highest weight of 23.83 grams and 10.73 mm grain 1000 weight highest seed during seeding date and this cultivar fourth highest HARVEST INDEX of 50.49% won.
