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 study the effect of organic fertilizer on the growth and yield of GH-63 soybeans on inland peat. The peat used was taken from Kalampangan Village and the land conditions had never been used for agricultural cultivation. The study was conducted in the Peat Techno Park area of ​​Palangka Raya University. Using a Completely Randomized Design, with 4 treatments of Rhizoka compound organic fertilizer dosage, namely H0 = 0 g.kg seed-1, H1 = 10 g.kg seed-1, H2 = 20 g.kg seed-1, H3 = 30 g.kg seed-1. Each treatment was repeated 5 times and because there were destructive and non destructive observations, the study was conducted in 2 (two) equal series. Data were analyzed by analysis of variance at the 5% and 1% levels. If the results of the analysis of variance indicate a significant effect, it is continued with the BNJ test at the 5% level. The results showed that treatment H3 = 30 g.kg seed-1 as the best treatment in all parameters, namely leaf area (77.03 cm2), effective root nodule weight (1.015 g), root dry weight (1.04 g), loss dry weight (3.71 g), root extinction ratio (3.64 g), number of seeds (1.98 seeds) and seed weight (1.15 g) compared H0 = 0 g.kg seed-1. The dose dose of biofertilizer is 30 g.kg seed-1 as the best dose for the growth and yield of GH-63 soybean plants on inland peat.
