Abstract

Ultisol is broad suboptimal soils, need to be developed to increase for foods and animal feeds, but properties of physics and chemistry by the soils bad. This research was aimed to studied the influence of compost derived from titonia plus rice straw in improving chemical properties of Ultisol and corn production. This researh was conducted in glasshouse and Soil Laboratory of Agriculture Faculty, Andalas University, Padang, West Sumatra, Indonesia from January to July 2017. The experiment consisted of 5 treatments (0.00; 2.50; 5.00;7.50; 10.00 tonha-1. with 3 replications. Soil data resulted were compared to the soil criteria, while corn data were statistically analyzed the variance and continued using DNMRT at 0.05 level of significance, if F-calculated > F-table. The results of research showed that optimum dosage for repaired chemical properties of 7,50 tonha-1. It dosage soil pH 6,18 unit; available P by 17,64ppm; CEC by 18,38cmol(kg)-1; organic-C by 1,27%, total-N by 0,23%; K-exch. by 0,49cmol(kg)-1; Ca-exch. by 2,63 cmol(kg)-1; Mg-exch. by 0,57cmol(kg)-1 dan Na-exch. by 0,39cmol(kg)-1, with dry weight of seed by 85,48gpot-1; dry weight of straw by 75,84gpot-1 and dry weight of 100 seed by 25,50g. Key words : Compost derived from titonia plus rice straw, corn, Ultisol.

苯酚和麦秆与土壤的化学特性和在ULTISOL上生产玉米的特性结合在一起

Ultisol是广泛的次优土壤，需要开发以增加用于食品和动物饲料，但土壤的物理和化学性质较差。本试验旨在研究水稻秸秆加钛堆肥对提高Ultisol化学性能和玉米产量的影响。本研究于2017年1月至7月在印度尼西亚西苏门答腊岛巴东的安达拉斯大学农学院温室和土壤实验室进行。试验共5个处理(0.00;2.50;5.00; 7.50;10.00 tonha-1。有3个复制。将得到的土壤数据与土壤标准进行比较，对玉米数据进行方差统计分析，并继续使用DNMRT进行0.05显著性水平的分析，如果f -计算> f -表。研究结果表明，修复化学性能的最佳用量为7,50 tonha-1。它投加土壤pH 6、18单位;可用磷降低17.64 ppm;CEC减重18.38 cmol(kg)-1;有机碳减少1.27%，全氮减少0.23%;K-exch。0, 49 cmol(公斤)1;Ca-exch。2,63 cmol(kg)-1;Mg-exch。以0.57 cmol(kg)-1 dan na为单位。0.39 cmol(kg)-1，干重85,48gpot-1;秸秆干重为75,84gpot-1, 100粒种子干重为25,50g。关键词:钛加稻草堆肥;玉米;Ultisol;
