摘要
在大田条件下，研究了促生根瘤菌(PGPR)和磷肥对辣椒炭疽病、植株生长和产量的影响。本研究采用双因素分区设计。第一个因素是PGPR的应用，它包括两种治疗方法;没有PGPR和有PGPR…第二个因素是磷肥的施用，包括4种处理的sp36肥料;250公斤，187.5公斤，125公斤和62.5公斤。施磷肥对辣椒生长参数有影响，但对鼻窦病无影响。在田间施用时，PGPR能有效地防治管鼻病，提高植株的生长参数和产量。施用PGPR可提高处理种子的出苗率和活力指数。在生长方面，PGPR与磷肥用量存在交互作用，最佳田间用量为125 kg SP 36/ha。
Interaksi Plant Growth Promoting Rhizobacteria Dosis Pemupukan P dalam Memacu Pertumbuhan dan Mengendalikan Penyakit Antraknosa pada Cabai Merah
The aims of this research were to investigate the effect of Plant Growth-Promoting Rhizobacteria (PGPR) and P fertilizer on anthtracnose caused by Colletotrichum sp. , plant growth and yield of hot pepper under field condition.. The research was arranged in split plot design with two factors. The first factor is aplication of PGPR which consists of two treatments; without PGPR and with PGPR.. The second factor is application of P fertilizer which consists of four treatment of SP 36 fertilizers; 250 kg , 187.5 kg , 125 kg, and 62.5 kg . Application P fertilizer affect growth parameters of chili pepper but have no effect on antrachnose disease. PGPR was able to control antrachnose under field application, and promoted plant growth parameters and yield. PGPR application increase emergence rate and vigor index of treated seeds. There was interaction between PGPR and P fertilizer dose regarding with growth, with optimum field dose is 125 kg SP 36/ha.
