Abstract

Rhizobacteria was a colonialist bacterial at rooting area that had capacity to produce IAA and enhance plant growth. Rhizobacteria indigenus chili had ability to produce IAA and induces various of plant growth. IAA production was not always linked with the ability to enhance plant growth. Obtained there were 11 isolates with various of morphological characters and had ability as RMSD (Plant Growt Promoting Rhizobacteria) with an effective increase in growth from 57.88 to 82.80%.Key words: Rhizobacteria, IAA, Growth, Chili Rhizosfer

Abstract

Kegiatan diseminasi teknologi pupuk kandang sapi plus rizobakteri pada tanaman kakao dilakukan di Kecamatan Guguak dan Akabiluru Kabupaten Lima Puluh Kota yang dimulai dari bulan Maret sampai dengan November 2018. Kegiatan ini bertujuan untuk mengenalkan teknologi formulasi pupuk kandang plus rizobakteri pada kelompok tani kakao. Inovasi, buah lobek, maju sejahtera dan aroma menggunakan metode penyuluhan. Pentingny kegiatan ini dilakukan disebabkan oleh tingginya kejadian dan keparahan penyakit VSD di Kecamatan Guguak dan Akabiluru Kabuparten Limapuluh Kota yang mencapai 86,60%. Untuk itu, diperlukan teknologi pengendalian yang mudah dibuat, murah dan bahan baku yang mudah diperoleh disekitar petani. Penggunaan air kelapa merupakan salah satu perbanyakan bakteri Serratia maresescens dan Pseudomonas fluorescens yang nanti akan diformulasi dengan pupuk kandang. Kegiatan ini meliputi: pemantauan tingkat serangan OPT dilahan kelompok tani kakao, kemudian dilanjutkan dengan penyuluhan, pelatihan, dan evaluasi hasil kegiatan. Dari hasil kegiatan bahwa kegiatan ini mampu meningkatkan pengetahuan petani terhadap penggunaan biofertilizer yang berasal dari bakteri yang diformulasikan dengan air kelapa dan pupuk kandang, sehingga penggunaan formulasi ini mampu mengurangi biaya penggunaan pupuk kimia yang memiliki harga yang mahal.

Abstract

Yellow leaf curl disease is the primary disease in chili plants with up to 100% losses. Detection from the field showed a mixed infection between Geminivirus or Pepper Yellow Leaf Curl Virus (PYLCV) and several viruses, including Chilli Veinal Mottle Virus (ChiVMV) and Cucumber mosaic Virus (CMV). Therefore, this study aimed to determine the role of PYLCV and ChiVMV dual infection in influencing the development of chili yellow leaf curl disease. This study used a completely randomized design (CRD) with six treatments and ten replications. The treatments used were multiple Geminiviruses and ChiVMV infections simultaneously, before ChiVMV co-infection, after Geminivirus infection, single infection and whithout infection viruses. The results showed that the presence of ChiVMV infection before, after, and concurrently with Geminiviruses infection could increase the yellow leaf curl disease intensity and reduce plant height and wet weight growth. The mean scale value of ChiVMV infection before, after, and concurrently with Geminiviruses infection were 3.38, 3.90 and 3.58 compared to single Geminiviruses infection (scale of 3.20) and single ChiVMV (scale of 1.33). The interaction analysis of ChiVMV and geminiviruses infections based on the percentage reduction in plant growth height and wet weight showed additive interaction. ChiVMV co-infection further exacerbated the incidence of yellow leaf curl diseases in chilies.

Abstract

Anthracnose is one of the most important seed-borne diseases in chili plants because this disease can reduce the quantity and quality of chilies and cause substantial economic losses. The aim of this study was to obtain the best isolates from various types of endophytic fungi Beauveria bassiana in suppressing the growth of pathogens. chili seed borne disease caused by the fungus Colletotrichum spp. The design used in this study was a completely randomized design (CRD) consisting of 6 treatments. The treatments consisted of control and 5 types of B. bassiana isolates (PD114, TD312, WS, BbKo, KT2B23). Parameters observed in this study were chili seeds that were attacked by Colletotrichum spp., normal seed germination on paper-to-paper test, length of plumule and radicle. Results. The study showed that different types of B. bassiana isolates could reduce the attack rate of seed-borne pathogenic fungi Colletotrichum spp. KT2B23 isolate was the best isolate in suppressing chili seed-borne pathogens.

Abstract

Plant Growth Promoting Rhizobacteria (PGPR) plus manure technology is designed to control the vascular streak dieback disease (VSD) which attacks cocoa plants, and improve the plant growth. This research aims to compare the cost of using conventional manure and PGPR plus manure technology. This research was designed in a descriptive quantitative approach using cencus data of 43 people who use PGPR plus manure in Kabupaten Limapuluh Kota. The result shows that the conventional fertilizer costs is more expensive than the PGPR plus manure formula. Therefore, it PGPR plus manure formula is recommended for the cacao farmers in Kabupaten Limapuluh Kota.

Abstract

Nagari Sungai Abang is one of the areas in Lubuk Alung District, one of the rice production centers in Padang Pariaman Regency. One farming group that intensively cultivates rice is the Farming Business group. The problem with the farmer groups is their ignorance of the benefits of straw as a source of organic matter in the soil. The composting process is long, so farmers always burn rice straw after harvest in preparation for planting the following season. If the burning of straw is carried out continuously, it is feared that nutrients will be deficient in the soil. This activity aims to empower Farming Business groups in Nagari Sungai Abang, Lubuk Alung District, to utilize Plant Growth Promoting Rhizobacteria (PGPR) as a bio activator in making straw compost as organic fertilizer and an alternative to addressing the problem of straw waste in Nagari Sungai Abang, Lubuk Alung. This activity has been carried out in the Farming Group of Farmers in Sungai Abang Dalam Nagari Sungai Abang, Lubuk Alung District, Padang Pariaman Regency. The method used is outreach, counseling, and training to demonstrate making PGPR suspension and compost from straw. From the activities that have been carried out, ready-to-use PGPR is obtained as a bio activator reproduced in coconut water media and used as a bio activator to speed up the composting process. The conclusion of this activity is increasing farmers' understanding of the benefits of straw as a raw material for compost and the use of PGPR as a bioactivator in making straw compost.

Abstract

Tanaman mentimun varietas lokal Padang merupakan tanaman sayuran unggulan bagi petani perkotaan karena umur panen yang pendek. Hasil survei menemukan adanya gejala bercak kuning dan klorosis dengan tulang daun hijau. Gejala ini mirip dengan infeksi Papaya ring spot virus (PRSV) yang menginfeksi mentimun di Jawa dan Zucchini yellow mosaic virus (ZYMV) yang menginfeksi mentimun pada umumnya. Deteksi virus dilakukan dengan teknik reverse transcription polymerase chain reaction (RT-PCR) menggunakan primer spesifik PRSV dan primer universal Potyvirus, perunutan dan analisis DNA. RT-PCR menggunakan primer spesifik PRSV DNA target tidak menghasilkan pita DNA, namun pita DNA dengan ukuran ±320 pb berhasil teramplifikasi dengan primer universal Potyvirus. Analisis sikuen nukleotida menunjukkan bahwa similaritas virus tertinggi sebesar 93.8% dan 93.5%, berturut-turut dengan ZYMV isolat Singapura dan India. Infeksi ZYMV merupakan kejadian pertama pada tanaman mentimun di Padang, Sumatera Barat.
