Indonesian Abstract

Budidaya pertanian pada saat ini banyak menggunakan teknik budidaya secara konvensional yang membutuhkan lahan luas. Disisi lain pertambahan jumlah penduduk yang terus meningkat menyebabkan kompetisi terhadap lahan pertanian. Terdapat alih fungsi lahan menjadi lahan non pertanian, seperti perumahan, areal industri dan gedung perkantoran menyebabkan lahan yang akan digunakan untuk budidaya menjadi sangat terbatas. Di Indonesia, produksi pertanian terutama pangan masih dominan diproduksi di Pulau Jawa, padahal 70% penduduk berdomisili di Pulau Jawa. Keadaan ini semakin mempersempit lahan pertanian. Salah satu alternatif budidaya yang dapat diterapkan selain menggunakan teknik konvensional yaitu dengan menggunakan teknik budidaya sistem vertikultur. Pada sistem vertikultur media tanam menjadi kunci utama perakaran tanaman dalam menyerap unsur hara dari media tanam yang terbatas. Penambahan bahan organik, mikoriza dan PGPR (Plant Growth Promoting Rhizobacteria) ke dalam media tanam akan mengoptimalkan pertumbuhan tanaman. Inokulasi mikoriza dan PGPR (Plant Growth Promoting Rhizobacteria) juga mampu meningkatkan kesuburan tanah. Jamur mikoriza memiliki banyak manfaat bagi tanaman antara lain dapat meningkatkan penyerapan unsur hara, meningkatkan ketahanan terhadap serangan patogen, serta dapat meningkatkan ketahanan terhadap kondisi kekeringan (Simanungkalit, 2001), sedangkan rhizobacter atau PGPR (Plant Growth Promoting Rhizobacteria) ialah kelompok bakteri yang dapat memacu pertumbuhan tanaman. Menurut Wahyudi (2009), PGPR berperan penting dalam meningkatkan pertumbuhan tanaman, hasil panen dan kesuburan lahan. Penelitian dilaksanakan pada bulan Februari hingga April 2016 di Desa Pandanrejo, Kecamatan Bumiaji, Kota Batu, Jawa Timur. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 6 perlakuan yang diulang sebanyak 4 kali ulangan. Perlakuan terdiri dari P1 = Tanah (Kontrol), P2 = Tanah + Bahan Organik, P3 = Tanah + Mikoriza, P4 = Tanah + Rhizobacteria, P5 = Tanah + Bahan Organik + Mikoriza dan P6 = Tanah + Bahan Organik + Rhizobacteria. Parameter yang diamati ialah panjang tanaman, jumlah daun, luas daun, jumlah anakan per rumpun, jumlah umbi panen, bobot umbi segar, bobot tanaman total kering matahari. Analisa data menggunakan analisa ragam (uji F) dengan taraf 5%. Apabila terdapat pengaruh nyata dilanjutkan dengan uji Beda Nyata Terkecil (BNT) dengan taraf 5%. Hasil penelitian menunjukkan penggunaan media tanam yang diberi bahan organik, mikoriza dan PGPR pada sistem vertikultur berpengaruh nyata terhadap parameter panjang tanaman, luas daun, jumlah daun per tanaman, jumlah anakan per tanaman, jumlah umbi per tanaman, bobot segar total tanaman, bobot kering tanaman. Perlakuan media tanah yang diberi mikoriza mempunyai bobot segarumbi per tanaman dan per m2 yang sama dengan media tanah + bahan organik + mikoriza dan tanah + bahan organik + PGPR. Pemberian mikoriza, bahan organik + mikoriza dan bahan organik + PGPR pada media tanah akan meningkatkan bobot segar umbi per tanaman dan per m2 23,08%, 34,87% dan 15,22% dibanding dengan media tanah.

English Abstract

Agricultural cultivation in recent years, using conventional farming techniques that require extensive land. On the other hand the number of people who constantly rising competition for agricultural land. There is land conversion into non-agricultural land, such as residential, industrial areas and office buildings cause the land to be used for cultivation is very limited. In Indonesia, agricultural production, especially food production is still dominant in Java, while 70% of the population live on the island of Java. The situation is further narrowed agricultural land. One alternative cultivation which can be applied in addition to using conventional techniques using the techniques of cultivation vertikultur system. In vertikultur system of growing media is the key factor in the plant roots absorb nutrients from the growth media is limited. The addition of organic matter, mycorrhiza and PGPR (Plant Growth Promoting Rhizobacteria) into the planting medium will optimize plant growth. Mycorrhizal inoculation and PGPR (Plant Growth Promoting Rhizobacteria) also can improve soil fertility. Mycorrhizal fungi has many benefits for plants, among others, can increase the absorption of nutrients, increased resistance to pathogen attack, and can increase resistance to drought conditions (Simanungkalit, 2001). While rhizobacter or PGPR (Plant Growth Promoting Rhizobacteria) is a group of bacteria that can stimulate plant growth. According to Wahyudi (2009), PGPR important role in improving the growth of plants, crops and soil fertility. The research was conducted in February until April 2016 in Pandanrejo village, Bumiaji, Batu City, East Java. This research used Randomize Block Design (RBD) with six treatments and four replications, such as P1 = soil (Control), P2= Soil + Organic Matter, P3= Soil + Mycorrhiza, P4= Soil + Rhizobacteria, P5= Soil + Organic Matter + Mycorrhizae and P6= Soil + Organic Matter + Rhizobacteria. Parameter observed is long plant, number of leaves, leaf area, Number of tillers per hill, number of tuber crops, fresh tuber weight, total plant dry weight of the sun. Data had been analyzed was using analysis of variance test (F test) with 5 % level. If there was a significant effect then followed by Least Siginificance Difference (LSD) at 5 % level. The results showed the use of growing media by organic material, mycorrhizal and the PGPR on the system vertikultur produce length parameter plant, leaf area, number of leaves per plant, number of tillers per plant, number of tubers per plant, fresh weight of total plant dry weight of plants more greater than in the soil media. Treatment by mycorrhizal soil media have fresh weight of tubers per plant and per m2 same media + soil organic matter and soil mycorrhiza + + + PGPR organic material. Award mycorrhiza, mycorrhizal + organic matter and organic matter in the soil medium + PGPR will increase the fresh weight of tubers per plant and per m2 of 23.08%, 34.87% and 15.22% compared with the soil media.
