Abstract

Corn (Zea mays L.) is an important food because corn is the second source of carbohydrates after rice. Seeds are one of the important components in the successful increase of agricultural production. This study aims to determine the type of fungi associated to corn seed (Zea mays L.) conducted from April to May 2017 at the faculty of agriculture, Timor University. Using Completely Randomized Design (RAL) Factorials and methods used are sampling, observation and pathogen identification performed by morphological characterization, Seedling power testing and maximum growth potential by the UKDdp method. The seeds used are small white local varieties, large white local varieties and hybrids, derived from several localities based on the locality of Eban 1000 meters above sea level, Mamsena 400-800 meters above sea level, Wini 100-200 meters above sea level. The results of identification were obtained by two genera of Aspergillus sp1, Aspergillus sp2, Aspergillus sp3 and Fusarium sp, Aspergillus sp1 highest fungal attack on small local varieties 7.78% and height of place T2 (Wini), Fusarium sp highest on hybrid corn varieties 40.00% and height of the highest place on T1 (Eban) 8.67%. The test of seed germination in the three varieties ranged between 16.44% -26.00%.

Abstract

Wheat (Triticum spp.) Is a cereal plant, has a fairly high nutrient content. The area of North Central Timor has prospects for wheat development. The existence of pathogens in wheat crops has not been observed and identified because there has never been any wheat cultivation in the area. The purpose of this study is to know other diseases that attack wheat crops when introduced to North Central Timor District, East Nusa Tenggara Province. The methods used were wheat cultivation, disease observation, and non-primary disease identification. Varieties of grain grown are varieties of Dewata, Selayar, and Nias. Observation of the incidence and severity of disease performed every 4 weeks. Identification of pathogens is done by morphological characterization with the help of identification keys. Laboratory research for disease identification was done in Plant Micropology Laboratory, Department of Plant Protection, Bogor Agricultural University. Other diseases that infect wheat crops are Fusarium shoots, leaf spot, Curvularia and Helminthosporium hulls, and twisted leaves. The percentage of incidence of all four diseases is very low.
