Abstract

            Penyakit pasca panen yang disebabkan oleh mikroba menyebabkan kerugian yang sangat besar setiap tahunnya. Pada pertanian konvensional, fungisida sudah digunakan selama bertahun-tahun untuk mengendalikan patogen pada tanaman. Sebagaimana telah diketahui, penggunaan bahan kimia secara terus menerus dapat berdampak buruk terhadap lingkungan dan menyebabkan resistensi.  Ozon telah dianjurkan oleh para ahli  sebagai alternatif pengendalian penggunaan bahan sintetik pada pengawetan bahan makanan karena ozon tidak meninggalkan residu pada bahan simpanan sehingga lebih aman untuk dikonsumsi.           Penelitian ini bertujuan ini untuk mengetahui pengaruh ozon pada konsentrasi rendah (180 ppb) terhadap perkembangan koloni dan spora yang dihasilkan oleh Botrytis aclada secara in vitro. Dua tipe inokulum digunakan pada penelitian ini adalah miselia dan spora.  Keduanya merupakan penyebab kerusakan pada bahan simpanan. Jamur yang diuji disimpan di dalam kotak yang dialiri ozon dengan suhu 7-8oC selama 14 hari. Pengamatan terhadap perkembangan koloni dilakukan dengan mengukur diameter koloni, sementara spora yang dihasilkan diamati pada hari ke 14 masa inkubasi. Hasil penelitian menunjukkan bahwa pemaparan ozon pada konsentrasi 180 ppb selama 14 hari tidak menurunkan perkembangan koloni  B. aclada, tetapi efektif mengurangi jumlah spora yang dihasilkan.

Abstract

Physiologycal Performance Comparison of Rice from Local and National Genotype to Overcome Drought ABSTRACT. Rice (Oryza sativa) is a major food commodity in the world that affected by global warming. It can be seen from crop harvest failure due to drought in many parts of the world. It is necessary to promote Land Race which has adapted to specific conditions, this is to strengthen national seed systems. This study aimed to compare the character of national varieties with local varieties that allow for superior varieties such as Cirata, Inpari 7, Ciherang, IR 64, Situ Patenggang, Situ Bagendid, Limboto and Towuti as a control and compare with 11 local genotypes (Rom Mokot, Pade Mas, Salah Manyang Ru, Bo Santeut, Si Gupai, Si Kuneng, Pade Barcelona, Sanbei, Ramoes, Si Puteh and Si Tandun) were germinated in a solution of PEG 6000 2,5% (25 grams / liter of solution). The results showed that local genotype have characters that can match with the national release varieties in the benchmark vigor reflected in germination rate, simultaneity germination and T50. Local genotype Sitandun, Si Puteh, Ramos, Sanbe, Pade Barcelona, Bo Santeut, Si gupai and Pade Mas reached 50% germination even faster than the national release varieties except Towuti and Limboto. For simultaneity germination, local genotypes Pade barcelona and Sanbe equal to Towuti, Ciherang and Inpari 7. For germination rate, local genotype Pade Mas, Pade Barcelona, Sanbe, Ramos, and Siputeh equal to Towuti, Inpari 7, Ciherang and Situ Patenggang.

Abstract

Objectives of the study were to determine effects of organic fertilizer on growth and yield of two varieties of tomato as well as the interaction between both factors. Factors studied were 1) types of organic fertilizer, consisted of 3 levels: manure, compost and green manure and 2) varieties of tomatoes, consisted of two levels: Viccario F1 and San Marino F1. Variables observed were plant height and stem diameter at ages 15, 30 and 45 days after transplanting (DAT), fruit numbers, and fruit weight for 5 times of harvest. The results showed that types of organic fertilizer exerted significant effects on plant height at age of 15 and 30 DAT, plant stem diameter at age 15 and 30 DAT, fruit numbers and fruit weight.  The best growth of tomato was on green manure.  Varieties also exerted significant effects on plant height at ages 15, 30 and 45 DAT, stem diameter at ages 30 and 45 DAT,  fruit numbers and fruit weight, but no significant effect on stem diameter at age 15 DAT. The best growth and fruit numbers wer found at Viccario, while the highest fruit weight was found at variety San Marino. There was a significant interaction between types of organic fertilizer and tomato varieties on plant height at age 45 DAT, but no significant interaction on other variables. The best plant growth was found at the combination of Viccario-manure.

Abstract

Status of Arbuscular Mycorrhizal Fungi in Different Farming Systems and Age of Oil PalmABSTRACT. A survey was conducted to determine the Arbuscular Mycorrhiza Fungi (AMF) spore population in rhizosphere soils and its root colonization of oil palm belonging to four age class (2-3months, 2 years, 7 years, and 10 years) at PTPN I Estate plantation and smallholder farmer plantation in Cot Girek Aceh Utara. The methods used were direct isolation. The result showed that there were 14 species of AMF belongs to genus Glomus identified according to spore morphology, eight species at PTPN I and six species at smallholder oil palm plantation. AMF spore density at PTPN I and smallholder oil palm was 17.35 and 17.80 spore per 50g soil, respectively. Oil palm at 7 years old resulted in better AMF population, i.e. 53,7 spore per 50 g Soil. AMF colonization at oil palm rhizospere in both farming systems were low, i.e. 5.4% (PTPN I) and 2.9% (smallholder). Farming system and age of oil palm influenced the AMF population and root colonization, Spore density did not positively correlate with root colonization at different farming systems and age of oil palm.
