Abstract

Corn is one of the most important food crops in the world. Corn has a high nutritional content, such as carbohydrates, proteins, and fats. Corn can also be processed into various food and beverage products. Corn production in Indonesia currently still does not meet national needs, one of the factors that causes this is the low productivity of corn. Various efforts have been made to increase corn productivity, one of which is by using fertilizers. The purpose of this study was to examine the response of corn growth and production with a combination of microbial consortium, NPK, and ortho salicylic acid. This study used experimental research methods. Data collection techniques in this study were carried out by literature study and observation. The data that has been collected is analyzed descriptively. The results showed that the consortium combination of 1 dose of 5 ml + NPK 15 gr + leaf fertilizer 3 ml was significantly different to increase the best growth in leaf area, total plant weight, corn weight, fruit diameter (base and middle). Based on the results of the study, it can be concluded that the consortium combination of 1 dose of 5 ml + NPK 15 gr + Foliar fertilizer 3 ml can increase corn growth and production.

Abstract

Anthracnose disease caused by Colletottrichum capsici on chili plants that can damage yields by up to 80%. Control with fungicides has not been able to provide maximum results, because the fungus can move due to water splashes, especially in the rainy season. The use of antagonistic fungi against Colletotrichum capsici. has been widely published but is still limited to laboratory and greenhouse scales. This study aims to analyze the potential of Bogor isolate Trichoderma viride antagonist fungus against the fungus C. capsici through in-vitro study in the laboratory, screen houses, and field conditions. The experiment was structured using Complete Randomized Design (CRD) with parameters that measured respectively the antagonistic ability, and the percentage of attack by C. capsici and the severity of anthracnose disease on chili plants were both tested in screen house condition. Bogor Isolate T. viride has potential as a biological control agent for chili plants. This is proven by the ability to suppress the growth of C. capsici by 71% in vitro. The use of the fungus T. viride with a concentration of 7x106 conidia/ml (full strength) can suppress the development of anthracnose by 59 to 87% under screen house conditions. In other words, the pathogenicity of capsici in red chili plants shows a severity level of 13 to 41%.
