RICE RATOON YIELD RESPONSE TO MAIN CROPS CUTTING HEIGHT IN TIDAL SWAMP USING DIRECT SEEDING SYSTEM
Abstract: This study was aimed
to evaluate the effect of main crops harvest cutting height on the yield of
rice ratoon in the tidal swamp by using direct seeding system. The experiment
was conducted in Telang Sari village, District of Tanjung Lago, Banyuasin,
South Sumatra Province from November 2013 to April 2014. It measured plots 4 x
5 m through a randomized block design with 5 replications. The treatment was
main crops harvest cutting height of 10, 20, 30, 40 and 50 cm above the soil
surface. The results showed that the effect of cutting height on rice ratoon
yield depends on the condition of photosynthetic and the amount of remaining
nodes on the main crops stubble as an emergence ratoon shoots. The main crops
cutting height of 20-40 cm above the soil surface increased the number of productive
tillers, grain weight per hill, yield per plot, ratoon ability to grow per
plot, and the rice ratoon/main crops yield ratio in tidal land by using direct
seeding system.
