Abstract

This study was aimed to detect and identify seed-borne pathogenic fungi in six local rice varieties of Siam Unus, Karangdukuh, Mayang, Gumpal Kuning, Gumpal Putih, and Siam Arjuna in Kapuas Regency. In addition, the objective of this study was also to determine the effect of seed pathogens on the physiological quality and the percentage of infected seeds. The research location was at the Agricultural Cultivation Laboratory, Faculty of Agriculture, University of Palangka Raya, and the study was carried out from September 2020 to February 2021. Seed health testing used the filter method (blotter test), isolation and identification of seed-borne pathogenic fungi using the agar method. The variables observed included macroscopic morphology of pathogens in petri dishes and microscopic evaluation using a compound microscope, seed germination, percentage of infected seeds, frequency of microorganism findings and pathogenicity tests on seed germination. Based on the results of the study, the identified pathogenic fungi carried by local varieties of rice seeds in Kapuas district were Aspergillus spp., A. flavus, A. niger, Curvularia sp. and Oidium sp., however these pathogens did not affect seed germination. The highest numbers of microorganisms observed on the agar method was Aspergillus spp. (37.5%), followed by Curvularia sp. (29%), whereas in the blotter test method the frequency of the fungus Curvularia sp. only 5.6%. The frequency of finding A. flavus and A. niger on the agar method was lower at 21.8%, while the fungus Oidium sp. was detected in very low percentage for only 0.9%. The pathogenic fungus Oidium sp. showed the highest level of pathogenicity in seeds reaching 21.7%, while the pathogenic A. niger, Curvularia sp. and A. flavus showed a lower infection rate, at 13.9% to 17.8% respectively. These pathogenic fungi might cause the seeds to not germinate normally such as leading to necrosis of the hypocotyl and plumules, stunted germination growth, and death of seed germination.

Abstract

The purpose of this study was to determine the best dose of PSB application on the growth of caisim plants in inland peat soil, and to determine the yield of caisim plants after PSB application in inland peat soil. This research was conducted in the field of Department of Agricultural Cultivation, University of Palangka Raya. This research was conducted from February 28, 2025 to April 28, 2025. This study used a single-factor Completely Randomized Design (CRD), namely the application of PSB (ml L-1) consisting of 5 treatment levels, namely: control, 25, 50, 75, and 100. Each treatment was repeated 4 times, resulting in 20 experimental units. The results showed that the application of PSB had a significant effect on the observation variables of plant height at all ages, number of leaves at 21 HST and 28 HST, plant fresh weight and plant dry weight. PSB application did not significantly affect the observation variables of the number of leaves at the age of 14 HST, leaf area and plant root weight. PSB application with a concentration of 100 ml L-1 =A4 gives the best results in all observations.
