Abstract

Hamidson H, Effendy E, Dewi WN, Ayundra SD. 2020. Test of multiple rice varieties (Oryza sativa L.) to the development of leaf blight disease caused by curvularia oryzae. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 109-116.  Rice is the main food commodity in Indonesia, since the  majority of  Indonesian populations use rice as their staple food. One of the common diseases that attack rice plants is leaf blight caused by pathogenic Curvularia oryzae. The objective of this research was to determine the reaction of five varieties of rice resistance to diseases caused by Curvularia oryzae. This research was conducted at Experimental Research Station and Phytopathology Laboratory of the Departement of Plant Pest and Disease, Faculty of Agriculture, Sriwijaya University from August to December 2016. Randomized block design was applied in this experiment by using 5 treatments and 10 replications. The Results showed that the highest percentage of leaf blight disease occured in P3 (Inpari 30) by 22,36% and the lowest percentage was found in P5 (varieties IR 10) by 2,85%.

Abstract

In South Sumatra, the ​​freshwater swamps is 157,846 hectares, with this wide freshwater swamps, it can be used for crops food  cultivation, one of which is maize. The purpose of this study was to provide information on the identification and attack of maize disease in freshwater swamps of South Sumatra. The research method was purposive sampling. The results of the study identification that the symptoms of maize leaf rust attack, seen from the physiology of maize leaves, were the lumps or pustules of orange color such as rust and the symptoms of maize leaf blight seen from the physiology of maize leaves, were small oval brownish lines like burning leaves. The leaf rust disease had an attack rate of 90% and the maize leaf blight reached 98%. Based on the results of this study, the main disease of maize attacking in the generative phase was the leaf rust (Puccinia polysora) and maize leaf blight (Bipolaris maydis).

Abstract

Planting resistant varieties is the most effective control method and is recommended because it is safe for the environment. The problem to be raised in this study was the use of the same variety of maize in every growing season by farmers. The use of one of these varieties could cause a decrease in yield due to the resistance of the variety to certain pests and diseases.  This study aimed to provide information in the form of the use of sweet maize varieties resistant to leaf blight and potential to be planted in the swampy lowland of South Sumatra. The varieties used in this study were Bonanza F1, MB-01 Sweet and Love Sweet varieties. Based on the results of the study, as a whole the use of several varieties had a significant effect on the severity of leaf blight. The results of this study showed that there were differences in the response to resistance of each variety to leaf blight caused by the fungus Exserohilum turcicum. The observation of disease severity was carried out only in the vegetative phase. The highest disease severity was found in the Bonanza, Love Sweet, and MB-01 Sweet varieties at 16.90%, 9.99% and 7.07% respectively. The production data showed that there was no significant effect on the leaf blight. The MB-01 Sweet variety had the potential to be planted on swampy soil because it had resistance to blight and had a high production rate.
