Abstract

Sterilisasi dan komposisi media merupakan faktor penentu dalam menghasilkan inokulan mikoriza yang berkualitas. Penelitian ini bertujuan untuk mendapatkan kualitas inokulan konsorsium FMA dan MHB yang terbaik dengan merekayasa media tanam dan metode sterilisasi. Percobaan telah dilakukan di rumah kaca menggunakan Rancangan Acak Kelompok (RAK) pola faktorial yang terdiri atas dua faktor perlakuan. Faktor pertama adalah sterilisasi media yang terdiri atas: (1) sterilisasi melalui pencucian dengan air, (2) sterilisasi menggunakan autoklaf, (3) sterilisasi dengan NaOCl, dan (4) sterilisasi dengan irradiasi gamma. Faktor kedua adalah komposisi media yang terdiri atas: (1) 100% zeolit, (2) 75% zeolit : 25% arang sekam, dan (3) 50% zeolit : 50% arang sekam. Hasil penelitian menunjukkan bahwa terdapat interaksi antara sterilisasi dan komposisi media terhadap jumlah spora MA, namun tidak berpengaruh terhadap nisbah pupus akar sorgum. Sterilisasi media secara mandiri berpengaruh terhadap populasi MHB. Perlakuan sterilisasi irradiasi gamma + komposisi media 75% zeolit : 25% arang sekam merupakan perlakuan yang cenderung lebih baik dalam meningkatkan jumlah spora MA, populasi MHB, dan nisbah pupus akar sorgum.

Abstract

Quality of biofertilizer such as arbuscular myorrhizal fungi could be improved through the selection of appropriate sterilization and composition of the medium. The objective of the experiment was to determine the effect of sterilization and carrier composition on root colonisation, root length and weight of sorghum root. A green house experiment was conducted in randomized block design. The factors were: 1. methods of sterilization (ie. control; autoclave; NaOCl 10%; Co-60 gamma irradiation), and 2. composition of the carrier of mycorrhiza (100% zeolite; 75% zeolite + 25% rice charcoal;  50% zeolite + 50% rice charcoal). Results showed that there was no interaction effect of sterilization and composition of carrier on root colonisation, root length and weight of sorghum root. However, different technique of sterilisation gave differences on root colonisation, root length and weight of sorghum root. Sterilization using NaOCl 10% was not recommended. Gamma Co-60 irradiation sterilization did not have difference with control and autoclave, however there was  tendency  that irradiation technique gave better results to all parameters measured.

Abstract

ABSTRACTApplication of liquid organic fertilizer formula plus on degraded soil to improve the productivity of the land and chili (Capsicum annuum L.) productionSoil exploitation in large numbers occurred in the District Wanaraja of Garut Regency. Excavation of soil more than 2 meters from the top layer for the manufacture of red bricks has exceeded the ability of the soil to re-establish its structure. So that the soils, which were agricultural lands, can be classified as degraded soils with less fertility and chemical properties. Lans reuse for agriculture requires adequate recovery and fertilizer input. This study aimed to determine the formula of LOF (liquid organic fertilizer) plus used with NPK compound fertilizer on degraded soil to improve the soil productivity. The design used was a Simple Randomized Block Design (RBD) by 10 combinations of LOF plus treatment with NPK compound fertilizer as follows: A = Control (degraded soil, no fertilizer), B = 0% LOF + 1 NPK, C = 0.25% LOF + 1 NPK, D = 0.50% LOF + 1 NPK, E = 0.75% LOF + 1 NPK, F = 1.00 % LOF + 1 NPK, G = 0.5% LOF + 3/4 NPK, H = 0.5% LOF + 1/2 NPK, I = 0.5% LOF + 1/4 NPK, J = 0.5 LOF + 0 NPK, and K = 1 NPK of normal soil that all replicated three times. The results showed that the degraded soil of red bricks required concentration of LOF above 0.5% to 1% when applied with 1 dose of standard NPK. It is able to balance the uptake of nutrients P, Ca, and B and percentage of fruitset in chili commodities equivalent to normal soil.Keywords: Chilli, Liquid Organic Faertilizer (LOF), NPK, Soil degrededABSTRAKEksploitasi tanah dalam jumlah yang besar terjadi di Kecamatan Wanaraja, Kabupaten Garut. Terjadinya penggalian tanah lebih dari 2 meter dari lapisan atas untuk pembuatan batu bata merah melampaui kemampuan tanah untuk membentuk struktur tanah kembali, sehingga tanah-tanah yang sebelumnya merupakan tanah pertanian ini dapat digolongkan menjadi tanah terdegradasi dengan sifat kimia kurang subur dan pemanfaatan kembali untuk pertanian memerlukan pemulihan dan input pupuk yang cukup. Penelitian ini bertujuan untuk mengetahui formula pupuk cair organik (PCO) plus yang digunakan bersama NPK pada tanah terdegradasi guna meningkatkan kembali produktvitas tanahnya. Rancangan yang digunakan adalah RAK sederhana dengan 10 kombinasi perlakuan PCO plus bersama NPK yaitu A = Kontrol (tanah terdegradasi, tanpa pupuk), B = 0% PCO + 1 NPK, C = 0,25% PCO + 1 NPK, D = 0,50% PCO + 1 NPK, E = 0,75% PCO + 1 NPK, F = 1,00% PCO + 1 NPK, G = 0,5% PCO + 3/4 NPK, H = 0,5% PCO + 1/2 NPK, I = 0,5% PCO + 1/4 NPK, J = 0,5 PCO + 0 NPK, dan K = 1 NPK tanah normal. Semua perlakuan diulang tiga kali. Hasil penelitian menunjukkan bahwa tanah terdegradasi bekas tambang batu bata merah memerlukan konsentrasi PCO di atas 0,5% sampai dengan 1% apabila diaplikasikan bersama 1 dosis NPKstandar. Hal ini mempu mengimbangi serapan hara P, Ca, dan B serta persen fruitset pada komoditas cabai setara dengan tanah normal.Kata Kunci: Cabai, NPK, Pupuk Cair Organik (PCO), Tanah terdegradasi
