ผลของเชื้อราอัลบัสคูล่าร์ไมคอร์ไรซ่าต่อการเจริญเติบโตของหญ้าเนเปีย์สายพันธุ์ปากช่อง1

Abstract

Study on arbuscular mycorrhizal fungi (AMF) to promote lrfyy cgy nutritive values zf Napier grzgn kcP 1 (Pennisetum purpureum cv. pakchong 1). The experiment was conducted at Agricultural Research and Training Center 100 rai, Nakorn Rachasima Rajabhat University, Amper Muang, Nakorn Rachasima Province during November 2014 to March 2015. The pot experiment design was RCBD with four treatments and four replications namely 1) control (no AMF inoculated and no urea fertilizer applied) 2) commercial AMF inoculated 3) 20kg/rai urea applied and 4) combination between commercial AM fungi and 20kg/rai urea fertilizer application. The commercial AMF could promote number of tillers per plant (p<0.05) and dry matter (p<0.01), while plant height (P>0.05), the number of leaf per stem (P>0.05), fresh weight (P>0.05) and dry weight (P>0.05) were opposite comparing with control. For chemical composition, AMF decreased of NDF (P<0.05) and ADF (P<0.05). Using of AMF was not increase in crude protein of Napier Pak Chong 1 compared with control. Application of urea fertilizer was higher promote growth and yield of Napier Pak Chong 1 more than other treatment. However, commercial AMF used decreased in dry matter (p<0.01). In addition the combination of commercial AMF and urea fertilizer increased in crude protein of Napier Pak Chong 1. The result indicated that arbuscular mycorrhizal fungi possibly used as biofertilizer for Napier Pak Chong 1. And the more future work will needed
