Management of Collar Rot of Chickpea (Cicer Arietinum) byTrichoderma Harzianumand Plant Growth Promoting RhizobacteriaCollar rot (Sclerotium rolfsii) of chickpea (Cicer arietinum) is one of the devastating soil-borne diseases of fungal origin, due to which 10-30% yield loss is recorded annually according to severity of the disease. Management of collar rot of chickpea is not feasible in the absence of effective soil fungicides. However,Trichoderma harzianumand plant growth promoting rhizobacteria (PGPR) have shown high efficacy against this diseasein vitroas well as in the field. We usedT. harzianum(104, 106and 108spore/ml) and two PGPRs (Pseudomonas fluorescensstrain 4 andP. aeruginosa) as foliar spray with the fresh and heat inactivated microorganisms. Foliar application ofT. harzianum(108spore/ml) andP. fluorescensstrain 4 (108cfu/ml) showed maximum efficacy in reducing plant mortality as compared to the control. Foliar application of fresh-and heat-inactivated (121°C for 10 min)P. fluorescensstrain 4, andT. harzianumreduced 15-25% plant mortality butP. aeruginosashowed very little disease control of 10-15%. However, regarding plant growth promotion, it was observed that fresh-and heat-inactivatedP. fluorescensstrain 4 showed maximum efficacy followed by fresh and heat inactivatedP. aeruginosaandT. harzianumas compared to the control. The disease-controlling efficacy was also associated with the increase in phenolic acid synthesis in chickpea plants. The control of chickpea collar rot by biocontrol agents is safe and ecologically sound and appears to be a healthy approach to the disease control.

ABSTRAK Nagari Sungai Durian Kabupaten Solok merupakan salah satu nagari yang memiliki berbagai permasalahan seperti kekeringan, tingginya jumlah lahan tidur dan jauhnya akses. Tanaman utama yang ditanam saat musim hujan adalah padi sawah, namun sebagian besar lahan menjadi lahan tidur saat musim kemarau. Solusi yang dapat ditawarkan adalah dengan penanaman tanaman palawija yang lebih tahan terhadap kekeringan dan penggunaan rizobakteri sebagai agens pengendali hama dan penyakit. Selain sebagai agens pengendali hama dan penyakit, penggunaan rizobakteri juga sebagai PGPR (Plant Growth Promoting Rhizobacteria) yang mampu meningkatkan pertumbuhan dan hasil tanaman. Tujuan dari program pengabdian masyarakat ini adalah memberikan pengetahuan kepada masyarakat dalam budidaya tanaman palawija dengan aplikasi teknologi rizobakteri indigenos. Kegiatan ini dilakukan dengan cara sosialisasi dan demonstrasi plot. Adapun luaran yang didapat dari program pengabdian masyarakat ini adalah :1) Masyarakat mendapatkan pengetahuan serta menguasai teknik budidaya tanaman palawija yang baik (jagung, singkong dan ubi jalar); 2) pengetahuan mengenai teknologi pemanfaatan rizobakteri sebagai agens hayati dalam pengendalian hama dan penyakit tanaman serta peningkatan pertumbuhan dan hasil tanaman palawija; 3) Mendapatkan produk pertanian organik (jagung, singkong dan ubi jalar) yang bebas dari penggunaan pupuk dan pestisida sintetik. Kata kunci : Agens hayati, Rizobakteri, PGPR, Tanaman palawija ABSTRACT Nagari Sungai Durian of Solok District is one of the village that has various problems such as drought, high number of unused land and the distance of urban access. The main crops in this village grown during the rainy season are wetland paddy, but most of the land becomes unused during the dry season. The solution that can be offered is by planting crops that are more resistant to drought and the use of rhizobacteria as pest and disease control agents. In addition to pest and disease control agents, the use of rhizobacteria which also called PGPR (Plant Growth Promoting Rhizobacteria) that can increase growth and yield of plants. The purpose of this community service program is to provide knowledge to the community in the cultivation of secondary crops with the application of indigenous rhizobacteria technology. This activity is done by socialization and demonstration plot. The outcomes obtained from this community service program are: 1) Communities gain knowledge and master good cultivation of secondary crops (corn, cassava and sweet potatoes); 2) knowledge of rhizobacteria utilization technology as biological agent in plant pests and diseases control and improvement of crops' growth and yield; 3) Obtain organic agricultural products (corn, cassava and sweet potato) that are free from the use of synthetic fertilizers and pesticides.
