Reclamation saline soil in the Central Plain for Asparagus   Punnee Rungsangchan, Somsri Arunin, Pirach Pongwichian and Arunee Yuvaniyama   ABSTRACT        The experiment on reclamation of saline soil in the Central plain for asparagus has been carried out at Field Crop Research Center, Suphanburi province during1991-1993. The experimental design was split plot with 16 treatments 3 replications, main plots were organic amendments (compost, rice husk ashes, bagasse and rice husks), sub plots were organic amendments at the rate of 3, 6, 9 and 12 tons/rai/year. Asparagus was planted in 48 plots of 4.5 x 4 m2, and the yields was begin to harvest at eight months after planting. Fresh weight yields and grade of asparagus were recorded. Soil and plant samples were collected for laboratory analysis.      The results showed that asparagus yield increased with increasing rate of amendment, organic matter amendments at the rate of 12 ton/rai gave the highest fresh weight yield of 567.082 kg/rai. Every rates of rice husk gave significantly higher yield than other amendments. The rate of12 tons/rai of rice husk gave the highest grade A yield of 378.44 kg/rai. The ECe of soil was reduced from 16.01 to 8.10 dS/m. Soil pH reduced from 5.66 to 5.07. Total Na was decreased but the soluble cations were increased. B/C ratio of treatments of bagasse at the rate of 12 ton/rai, rice husk at the rates of 3, 9 and 12 ton/rai were 1.04, 1.17, 1.03 and 1.08 ,respectively.        Keywords : saline soil in the Central, asparagus, organic amendments
