In Indonesia, production of corn are used for fodder (55%), food (30%), and seed (15%). The growth of corn plants is limited by the presence of pests, weeds, and plant diseases. Curvularia sp. causing leaf spot and could decrease corn production. Use of mycorrhiza can be used as a biological agent in preventing pathogens outbreaks. Isolates of Curvularia sp. fungal was sprayed on corn seed. This research was conducted in laboratorium and green house. Corn seedlings were grown on sterile soil media (control), mycorrhizal treatments (100g of mycorrhizal + Curvularia sp., 200g of mycorrhizal + Curvularia sp., 300g of mycorrhizal + Curvularia sp.) and Curvularia sp. The observed variables were plant height, number of leaves, rate of disease progression, fresh weight and dry weight of plant canopy. The results showed that application of 100g inoculum tend to increase plant growth to 26-27% and percentage of mycorrhizal colonization to 58,66% thereof can decrease pathogen infection on plant at 28 day after planting.

Dryland in Indonesia has been dominated by acid soils, so that availability of phosphate (P) becomes the main obstacle in improving outcomes and only 10-30% of fertilizer P can be utilized by plants. One of the solution to meet the needs of phosphate is by utilization of mycorrhizal biofertilizer. These experiments were divided into several phases: 1) Looking for phases of mycorrhizal, 2) the laboratory analysis, 3) Testing phase on plants that were carried out by using polybags with sterile soil. The experiment was designed with a complete randomized block design (RAKL) by using a factor that consists of 6 treatments that are: 1) Without mycorrhizal inoculum (M0), 2) Mycorrhizal inoculum 5 g + 50 Spores (M5), 3) Mycorrhizal inoculum 10 g + 50 spores (M10), 4) Mycorrhizal inoculum 15 g + 50 spores (M15), 5) Mycorrhizal inoculum 20 g + 50 spores (M20), 6) Commercial mycorrhizal 10 g (Mk). All treatments were repeated four times so that the total 24 pot experiment. The experiment results show that mycorrhizal treatment given on the corn crop has very significant (P <0.01) to the number of leaf age of 35, 49, 63 days after, leaf wide have age 49 days after plant, fresh weight, oven-dry weight, absorb P, number of spores, mycorrhizal infection and significant effect (P <0.05) to plant height age of 35, 49, 63 day after plant, 63 days after plant, leaf wide, and P-available.

Seed produced on three widely grown public corn (Zea mays L.) inbreds were tested for tolerance to drying injury. Inbred parents A632, B73, and Mo17 were grown in 1979 and 1980. The single cross H99 × H95 was used as a pollinator both years. Random ear samples were collected, to obtain ears with moisture percentages ranging from approximately 50 to 20%, and dried to 12% moisture at 35 °C, 40 °C, 45 °C, and 50 °C. Inbred parents were found to differ in tolerance to high drying temperatures. A632 was the most tolerant to high drying temperatures whereas B73 and Mo17 were relatively intolerant. Field performance of dried seed was similar to that observed in laboratory tests. Combined analyses yielded significant inbred-parent by harvest-moisture by drying-temperature interactions for germination and cold-test emergence percentages. These interactions do not allow for simple recommendations of safe harvest moistures and drying temperatures. Components from the combined analysis that had a P > F of 0.30 or less were then used to predict mean values for A632, B73, and Mo17 germination, cold-test emergence, seedling dry weight and the ratio of shoot to root dry weight. Values for the ratio variable indicated that root development is more susceptible to injury than is shoot development. These predicted values provide seed producers with information on the quality responses that they could expect when seed of A632, B73, or Mo17 is harvested at different moisture contents and dried at different drying temperatures.Key words: Drying, seed quality, Zea mays L.

Aluminum (Al) toxicity is one of the most limiting factors for productivity. This research was carried out to assess the influence of Al nutrient solution on plant height, dry weight and morphoanatomical alterations in corn (Zea mays L.) roots and leaves. The experiment was conducted in a greenhouse with five treatments consisting of Al doses (0, 25, 75, 150, and 300 µmol L-1) and six replications. The solutions were constantly aerated, and the pH was initially adjusted to 4.3. The shoot dry matter, root dry matter and plant height decreased significantly with increasing Al concentrations. Compared to the control plants, it was observed that the root growth of corn plants in Al solutions was inhibited, there were fewer lateral roots and the development of the root system reduced. The leaf anatomy of plants grown in solutions containing 75 and 300 µmol L-1 Al differed in few aspects from the control plants. The leaf sheaths of the plants exposed to Al had a uniseriate epidermis coated with a thin cuticle layer, and the cells of both the epidermis and the cortex were less developed. In the vascular bundle, the metaxylem and protoxylem had no secondary walls, and the diameter of both was much smaller than of the control plants.
