Abstract

Pada tahun 2013 telah berhasil diisolasi mikroorganisme tanah pada lahan budidaya tanaman cabai rawit asal Desa Condro, Lumajang Jawa Timur. Penelitian ini bertujuan untuk mengkaji pengaruh inokulan bakteri penambat nitrogen, bakteri pelarut fosfat dan mikoriza asal Desa Condro, Lumajang, Jawa Timur terhadap pertumbuhan tanaman cabai rawit. Penelitian ini menggunakan 2 faktor perlakuan, yaitu komposisi inokulan dan varietas tanaman cabai rawit. Parameter yang diamati meliputi tinggi tanaman, diameter batang, jumlah daun, panjang akar dan berat kering tanaman. Analisa data menggunakan uji ANOVA dan dilanjutkan dengan uji Tukey taraf kepercayaan 95%. Hasil uji ANOVA menunjukkan bahwa inokulan bakteri penambat nitrogen, bakteri pelarut fosfat dan mikoriza berpengaruh secara signifikan terhadap rata – rata pertumbuhan tanaman. Pemberian inokulan bakteri penambat nitrogen dan bakteri pelarut fosfat memberikan hasil rata – rata pertumbuhan tanaman paling baik pada varietas Bara dengan tinggi tanaman sebesar 9,0 cm, diameter batang sebesar 0,4 mm, jumlah daun sebanyak 7 helai, panjang akar sebesar 8,2 cm, dan berat kering tanaman sebesar 216,7 mg tanaman-1. ============================================================ By the end year of 2013, some microorganisms of cultivating land of pepper plant has been origin isolated from Desa Condro, Lumajang, East Java. This research aims to assess the influence of nitrogen fixing bacteria, phosphate solubilizing bacteria and mycorrhizal inoculants origin from Desa Condro, Lumajang, East Java to the pepper plant growth. This research use two factors for the treatment, namely inoculants composition and variety of pepper plant. The observed growth parameters, including plant height, stem diameter, number of leaves, root length and dry weight of plant. Data analysis using ANOVA test, then continued to the Tukey test based on level confidence of 95%. ANOVA test results showed that the nitrogen fixing bacteria, phosphate solubilizing bacteria and mycorrhizal inoculants well significantly influence the plant growth. The composition of nitrogen fixing and phosphate solubilizing bacteria inoculants have shown the best means of plant growth with the average of plant height was 9,0 cm, stem diameter was 0,4 mm, number of leaves were 7 strands, the length of root was 8,2 cm and dry weight of plant was 216,7 mg plant-1.
