“…The utilization of high-yielding or superior quality corn seeds is only around 60% of the total planting area [3]. Hybrid corn varieties produced by the Indonesian Agency for Agricultural Research and Development are generally multiplied and marketed by the private sectors, which obtain licenses, namely for Nasa 29 by 8 companies and Bima 20 URI by 14 companies [7]. High-yielding hybrid corn varieties that have been released have good adaptability; however, not all varieties can grow and develop in various agroecosystems, meaning that each variety will provide optimal results if planted on the appropriate land.…”

In long dry season (El Nino), thousand hectares of agricultural land in Indonesia to experience drought, and sometimes wildfires occur naturally. Land management without burning and environmentally friendly agricultural cultivation needs to be done in the long dry season. It is not recommended to use crop residue that is burned on the land, since the residue can be composted into organic matter which later is returned to the agricultural land as organic fertilizer. Currently, about 40% farmers use local corn varieties. Corn farming lands in Indonesia are generally deficient in nitrogen. Consequently, drought tolerant new superior corn varieties complemented with right dose fertilizer based on plant needs, especially N fertilizer, are needed to increase corn productivity in the dry season. This research aimed to ascertain adaptive hybrid corn varieties and right N fertilizer rate on the growth and productivity of corn planted on the land without burning. The experimental design was Randomized Complete Block Design consisting of 2 factors. The first factor was corn varieties, namely Bima 19, Nasa 29, and JH 21; whereas, the second factor was N fertilizer rate, namely 64, 86.5, 109, and 131.5 kg ha-1. The combination of the two factors consisted of 12 treatments, which were repeated 3 times. The results showed that there was an interaction between the new high yielding varieties and the N fertilizer rate on corn productivity. Greater yields were performed in Bima 19 with N rate of 109 and 131.5 kg ha-1 and Nasa 29 with N rate of 131.5 kg ha-1 i.e., 8.45, 7.94, and 8.04 t ha-1, respectively. Bima 19 and Nasa 29 are drought tolerant high yielding corn varieties.

“…Efforts can be made to increase maize production in Indonesia using superior seed varieties, such as hybrid maize. Hybrid maize is very responsive to fertilization, so its production potential is also high at 10-12 tons/ha (Hastini & Noviana, 2020).…”

Downy mildew is a significant disease of corn plants caused by the pathogenic fungus Peronosclerospora maydis, with attack rates reaching 95%. The application of slow-release fertilizer based on corn cob biochar is expected to increase the resistance of corn plants. Similarly, Bacillus sp. and Pseudomonas sp. are known as antagonistic microorganisms. Bacteria can produce antibiotic compounds that hydrolyze fungal cell walls, siderophores, and other antibiotic properties that inhibit pathogen growth. This study aims to determine the morphological characteristics of downy mildew-infected corn on biochar-applied land. Treatments were arranged factorially in a Factorial Randomized Block Design repeated four times. The treatment was the application of slow-release fertilizer from biochar mixed with NPK fertilizer, namely control, slow-release fertilizer, slow-release fertilizer + cow urine, and slow-release fertilizer + cow urine + bacteria (Azobacter and Bacillus). The results showed that slow-release fertilizer gave the best growth to both normal and downy mildew-affected maize plants. The stomata of typical corn leaves were more open with regular vascular bundles, while those affected by downy mildew had more closed and irregular stomata. The chlorophyll content index in downy mildew-affected maize can also improve by applying biochar-based slow-release fertilizer.

“…The stages in the cultivation of corn plants are selecting quality corn seeds and superior types so that they can grow well, the climate has direct sunlight intensity with open land that gets direct sunlight, this soil media has an important role in the development of a plant which must has good nutrient content, texture, and soil acidity. In corn plants, the pH of the soil is good around soil pH 5.5-7.5 (Hastini & Noviana, 2020).…”

Indonesia is one of the developing countries which has characteristics in one sector in agriculture, which is one source of income and improves the economy of farmers, but farmers in processing agricultural land are still not maximized as a means of productive plant land. This productive land requires a technology that can assist in land selection, the purpose of this research is to produce a Decision Support System for the Selection of Productive Land in Corn Plants Using a Web-Based Smart Method, and the author wants to implement the Smart method into the selection of productive land for corn plants that is safe in this system requires data that includes data criteria and alternatives. The results of the data are processed using intelligent methods so that it will produce alternative recommendations that have the highest value. this research can help coordinators of agricultural extension centers assist farmers in managing land to be productive.
