Abstract

Corn (Zea mays L.) is one of the agricultural products whose seeds are used for food. Therefore, a good storage method is needed in order to increase the percentage of seed quality. Storage is one of a series of activities carried out after harvest which aims to reduce or reduce seed moisture content and can also increase the vigor resistance and viability of seeds to the environment. There are two types of storage methods, namely traditional storage methods and modern storage methods. The modern storage method is a development of the traditional development method, only the tools and materials used are different. the lowest percentage germination rate of the six parameters observed was the traditional storage method in jerry cans. This means that the percentage of seed germination rates from the four methods with increased germination rate (>) is in accordance with the observed data even though the seed storage period is at the same time, namely from May to September.

Abstract

Seeds are said to be healthy if the seeds used are free of disease-causing microorganisms one of them is fungi. The purpose of this study was to obtain the type of pathogenic fungi that infect rice seeds. The research was conducted in the laboratory of Agricultural Faculty and Biology laboratory of Timor University since March - May 2017. The research used Completely Randomized Design of factorial pattern with two factors. The first factor consists of three varieties namely Ciherang, IR, and Siputih. The second factor consists of storage model ie storage in plastic sacks, Sokal, and cans. The results showed that the use of three varieties and models of seed packing material did not show any significant difference to germination. Maximum Growth Potential percentage between Siputih variety (97.33) was significantly different from IR varieties (72.00) and in seed model stored in the plastic sack (94.22) was significantly different from the seeds stored in the Sokal (68.88). Identification results found five fungi of the genus Aspergillus sp.1 and sp.2, Altenaria, Curvularia, Fusarium and Rhizopus that infect the seeds thus decreasing the germination power. The degree of fungal attack varies on varieties and storage models. The five fungal pathogens found, two fungi such as Aspergillus and Fusarium infect seeds with different storage areas lower, to reduce the infection rate of Altenaria fungus, Curvularia and Rhizopus can be treated fungicide.

Abstract

Seedling media is one of the factors that influence seed germination. The requirements for seed germinating are media constituent material have a porosity for water retention and air circulation. One of the porous material that can be used as seedling media is biochar. Characteristic of biochar depend on the pyrolisis temperature and the type of biomass. This study aims to determine the percentage conversion of biomass from 3 types of woody biomass to biochar, the chemical characteristics of biochar resulting from pyrolysis at 3 different temperatures, viability of lettuce seeds on seedlings media with biochar, soil, and compost. This study used a factorial completely randomized design that was repeated 3 times. The first factor is the type of woody biomass which consists of 3 levels, namely lac tree, eucalyptus, and acacia. While the second factor is the pyrolisis temperature which consists of 3 temperature variations namely 350 oC, 450 oC, and 550 oC. The results showed that the higher percentage of biochar yield was produced on the type of lac tree with pyrolysis temperature at 350 oC. Biochar pH is alkaline except for biochar from lac tree with pyrolysis temperature at 350 oC. The highest EC value is produced by eucalyptus biochar with a pyrolysis temperature at 550 oC. The type of eucalyptus biochar has C-total, N, P, and K content greater than the other, while the largest CEC value is produced by the type of lac tree biochar. The best seed germination of lettuce is produced by eucalyptus biochar at pyrolysis temperature on 450 oC. Generally, the type of acacia wood biochar gives the best germination in all pyrolisis temperatures.
