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

Pests and disease are one of the factors that cause yield loss of red chilli. Knowledge of the population dynamics of the main pests and diseases of red chilli can be used as the basis for recommendations for pest and disease control. The research aims to analyze pests and diseases population dynamics on red chilli cultivation, the influence of environmental factors and the influence of population dynamics on red chilli production. This research was conducted in Kereng Bangkirai Village Sebangau District, Kalampangan Village Sebangau District and Tanjung Pinang Village Pahandut District, Palangka Raya City. The research was conducted from December 2022 to March 2023. The research using a quantitative descriptive method. The sample plants used the diagonal plot sampling method, with an area of 4 m x 4 m. Observation were made in the morning once a week from transplanting to harvesting. The result showed that the dynamics of the main pest population of red chilli plants was influenced by the availability of food, the population of red chilli pests was high when the condition of the plant organs (leaves) was still at a young age which was suitable for its feed designation, the dynamics of anthracnose disease was influenced by temperature and humidity; Temperature and humidity do not always have a significant effect on pest and disease population dynamics. Fluctuating pest populations are influenced by the cultivation system applied by farmers, especially the use of synthetic pesticides; The higher number of pest and disease populations cause less production of red chilli plants.

Abstract

Pertumbuhan tanaman pakcoy sangat bergantung pada tingkat pH tanah media tanam. Salah satu upaya untuk meningkatkan pH tanah gambut rendah adalah dengan menggunakan serbuk cangkang telur ayam yang mengandung kalsium (Ca) sebesar 35,1-36,4%, lebih tinggi dibandingkan dengan kandungan kalsium pada kapur dolomit yang sebesar 21,70%. Tujuan penelitian ini adalah untuk menguji respons pertumbuhan dan hasil tanaman pakcoy terhadap pemberian serbuk cangkang telur ayam. Kemudian juga berupaya untuk menentukan dosis serbuk cangkang telur ayam yang dapat memberikan hasil terbaik pada tanaman pakcoy di tanah gambut. Selain itu, penelitian ini juga bertujuan untuk menguji respons pemberian serbuk cangkang telur ayam dalam meningkatkan pH tanah gambut pada budidaya tanaman pakcoy. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktor tunggal untuk mengetahui  perbedaan respons serbuk cangkang telur (T) terhadap dosis yang diberikan. Dosis serbuk cangkang telur yang digunakan sebanyak 1 t ha-1, 2 t ha-1, 3 t ha-1, 4 t ha-1, dan 5 t ha-1. Penelitian ini menunjukkan adanya korelasi positif antara dosis serbuk cangkang telur dengan pertumbuhan dan hasil tanaman. Secara khusus, dosis 5 t ha-1 serbuk cangkang telur memberikan hasil yang paling baik dalam hal lebar daun tanaman (7,1 cm) dan hasil tanaman (186,5 g tanaman-1). Selain itu, peningkatan dosis lebih lanjut dapat memberikan hasil yang lebih optimal pada tanaman pakcoy. Penambahan serbuk cangkang telur ayam pada tanah gambut menghasilkan kenaikan pH sebesar 0,89-1,59 poin sehingga menaikkan pH tanah dari 3,21 menjadi 4,8 dengan dosis 5 t ha-1.

Abstract

Penyakit bercak daun pada alpukat sangat penting karena dapat menyebar ke jaringan tanaman, seperti pada ranting, bunga, buah sehingga menyebabkan kematian tanaman, serangan dimulai dari lahan hingga ke penyimpanan (penyakit pasca panen). Tujuan penelitian yaitu untuk menguji konsentrasi ekstrak pasak bumi yang efektif dalam menghambat penyakit bercak daun yang disebabkan oleh jamur patogen C. gloeosporioides pada tanaman alpukat. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) terdiri dari 4 taraf perlakuan dengan 5 ulangan. Perlakuan terdiri dari 4 taraf, yaitu: P0 (control/tanpa ekstrak pasak bumi), P1 (ekstrak pasak bumi konsentrasi 15%), P2 (ekstrak pasak bumi konsentrasi 20%), dan P3(dikonafenazol 0,6 ml.L-1). Hasil penelitian menunjukan bahwa perlakuan ekstrak pasak bumi konsentrasi 20% (P2) mampu menghambat pertumbuhan bercak daun oleh jamur patogen dengan lama inkubasi rata-rata 6,2 hsi, mampu menekan jumlah bercak yang tumbuh pada daun dengan rata-rata jumlah bercak 17 dibanding dengan perlakuan ekstrak pasak bumi pada konsentrasi 15% (P1) dengan masa inkubasi yang lebih pendek dan jumlah bercak yang muncul pada daun lebih tinggi. Perlakuan ekstrak pasak bumi dengan konsentrasi 20% (P2) mampu menekan pertumbuhan patogen C. gloeosporioides dengan efektivitas pengendalian 59,14%, namun efektivitasnya lebih rendah dari dekonafenazol 0,6 ml.L-1 yang memiliki efektivitas pengendalian sebesar 71,63%.

Abstract

The aim of this research was to study the effect of adding nut extract or coconut water to PDA media on the growth and virulence of Metarhizium anisopliae in Tenebrio molitor larvae. The research used a Completely Randomized Design (CRD) with 5 treatments and 4 replications. The treatments tested consisted of; PDA media), KH = PDA media + 10% green bean extract, KM = PDA media + 10% red bean extract, KK = PDA media + 10% soybean extract, and K = PDA media + 20% coconut water. The observed variables consisted of; colony diameter, spore density per mL and T. molitor larvae mortality. The results of the study showed that the addition of nut extract or coconut water to PDA media had a very significant effect on the growth of the diameter of the M. anisopliae colony and the mortality of T. molitor larvae. The treatment of PDA media + 10% soybean extract and the treatment of PDA media + 20% coconut water had the same M. anisopliae colony growth at 24 dai of 90 mm which was significantly higher than the other media treatments, having a higher spore density of 155 x 106 and 105 x 106 per ml, respectively. Mortality of T. molitor larvae in the KK and K treatments at 16 daa of M. anisopliae spore suspension was 95% and 91.25%, respectively. The KK and K treatments were the best treatments for colony diameter growth, as well as the greatest mortality of T. molitor larvae.
