Abstract
The aim of the research was to determine the effect of nitrogen-fixing endophytic bacteria and N fertilizer on population of nitrogen-fixing (diazotroph) endophytic bacteria, N concentration and dry matter of red chili plant ( Capsicum annuum L.) on Inceptisols from Jatinangor. The experiment conducted design was Randomized Block Design in factorial pattern consisted of two factor and three replication. The first factor was diazotroph endophytic bacteriaconsisted two levels: without used diazotroph endophytic bacteria, and used diazotroph endophytic bacteria. The second factor was dosage of N anorganic fertilizer consisted four levels 0, 50, 100 and 150 kg N ha -1 . The results showed that there is interaction found between diazotroph endophytic bacteria and N inorganic fertilizer on population of diazotroph endhophytic bacteria but there were not interaction effect on N concentration and dry matter of red chili plant. Independenly, treatment giving diazotroph endophytic bacteria and N anorganic fertilizer showed not significant effect on N concentration of plant. While the treatment of diazotroph endophytic bacteria and 150 kg N ha -1 inorganic fertilizer were independenly each could significantly increased dry matter of red chili plant on Inceptisols from Jatinangor. Keywords: Diazotroph endophytic bacteria, N fertilizer, Red chili plant
研究了固氮内生细菌和施氮肥对红辣椒(Capsicum annuum L.)对赤藓菌(ineptisols)的固氮(重氮营养型)内生细菌数量、氮浓度和干物质的影响。试验设计为随机区组设计,因子模式为二因子三重复。第一个因素是重氮内生细菌,包括两个水平:不使用重氮内生细菌和使用重氮内生细菌。第二个因素是氮肥用量为0、50、100和150 kg N ha -1 4个水平。结果表明:重氮营养内生细菌与N无机肥料对重氮营养内生细菌种群有互作作用,但对红辣椒植株的N浓度和干物质没有互作作用。重氮内生细菌和氮肥单独处理对植株氮素浓度影响不显著。重氮营养内生细菌和150 kg N ha -1无机肥单独处理均能显著提高红辣椒植株的干物质含量。关键词:重氮营养内生细菌,氮肥,红辣椒植株
