Efficacy of organic fertilizer, biofertilizer and endophytic bacteria to control nematodes in robusta coffee

Abstract Coffee is a plantation crop that has high economic value. One of the obstacles in cultivation coffee plants attack plant parasitic nematodes, including Pratylenchus coffeae, Radopholus similis , and Meloidogyne spp. The reported nematode control technologies are implementation organic fertilizers, botanical pesticides, biological agents. This study aimed to determine effect fertilizer, biofertilizer, endophytic bacteria nematodes on Robusta plants. research conducted farmers’ infested by Sidomulyo village, Lampung, Indonesia. used randomized block design with 6 treatments: fertilizer + bacteria, biofertilizer (farmer’s technology). Biofertilizers were applied together fertilizers at beginning rainy season, 25 g/tree 3 kg/tree, respectively. Endophytic 100 ml/tree month after biofertilizer. observations performed population, growth, production robusta coffee. results showed application biofertilizers, could suppress population 50.56-70.71%. also increases growth productivity
