PGPR Preparation Training to Improve Cassava Production for KOPASAMU Farmers in Kalasan

Abstract

Cassava farmers grouped in Koperasi Sejahtera Muhammadiyah (KOPASAMU) in Kalasan often faced challenges of low production level of cassava (5 - 10 tonnes/ha) due to lack of growth and unhealthy conditions as a result of plant pest disturbance. Previous studies have demonstrated that such problem may be alleviated by the application of Plant Growth Promoting Rhizobacteria (PGPR). PGPR is a consortium of bacteria-producing plant growth hormones that improve cassava plant health and increases production. In addition to the use of PGPR, plant productivity may also be improved by using organic fertiliser, inoculated with mycorrhiza, stem wounding, and foliar fertiliser spray. The purpose of this community service was to improve farmers’ understanding and skills in applying PGPR to increase cassava production. The activities of the services were: (1) extension training on PGPR, (2) training on PGPR preparation, and (3) mentoring in the application of PGPR in cassava production demonstration plots (demplot). The results of the community services demonstrated that the extension programme has increased farmers’ understanding of PGPR by 100%, also resulting in an increase in farmers’ spirit and passion for applying PGPR. Following the extension programme, it was observed that the farmers’ skills have improved by 100%. However, among the farmers who were involved in the extension programme, 54.55% stated that they already mastered the PGPR preparation, while the other 45.45% stated that they required further training to improve their skills.
