Abstract

The low productivity and long harvesting period of local black rice causes this plant to be rarely cultivated by farmers in Indonesia. One way to increase the genetic diversity of black rice is by using gamma ray irradiation. This study aims to determine the genetic diversity and heritability value of M2 generation black rice resulting from gamma-ray irradiation. The research was conducted in February - June 2021 at the Screenhouse Universitas Perjuangan Tasikmalaya. The genetic material used was black rice M2 generation resulting from gamma ray irradiation with doses 200 gy and PH5 as a control. The research was conducted in 2 experimental stages. The first experiment was in the nursery where M2 seeds were planted with 1000 seeds and 200 seeds for the control. In the second study, the M2 generation black rice mutant was planted with 250 seedlings without replication and the control 10 plants were repeated three times. The results showed that there was a chlorophyll mutation in the M2 generation lines which produced color variations including albino 0.5%, xantha 42%, viridis 5%, tigrina 0.5%, normal 52% at 21 HSS. The survival ability of the black rice mutant was smaller than that of the control. The heritability values in the broad sense of the high category and high genetic diversity were found in the number of productive tillers, the number of total grain, and the number of empty grain. M2 generation black rice irradiated with 200 gy gamma rays was able to provide a response of longer flowering time, narrower flag leaves, lower weight per plant, less filled grain, and increased number of empty grain compared to control (PH5).

Abstract

Cekaman salinitas berdampak pada gangguan fisiologis dan menyebabkan penurunan produktivitas tanaman padi. Aplikasi bahan organik pada media tanam dapat dijadikan sebagai solusi untuk memperbaiki sifat-sifat tanah sehingga sesuai untuk media tumbuh tanaman. Selain itu, ketepatan umur bibit dapat menjadi kunci keberhasilan budidaya padi pada kondisi salinitas. Tujuan penelitian untuk mengkaji pertumbuhan dan hasil padi pada kondisi salin menggunakan penambahan bahan organik dan perbedaan umur bibit. Penelitian menggunakan RAL dua faktor, faktor pertama yaitu media tanam organik berupa pupuk kandang sapi, sekam bakar, kompos jerami, dan Azzolla pinnata, sedangkan faktor kedua yaitu umur bibit berupa 21 hari setelah semai (HSS) dan 28 HSS. Hasil penelitian menunjukkan bahwa media tanam organik berpengaruh nyata terhadap tinggi tanaman 8 MST, jumlah anakan 6 MST, panjang akar 6 MST, bobot kering akar 6 MST, dan panjang malai. Kombinasi media tanam organik dan umur bibit berpengaruh nyata terhadap bobot kering tajuk 6 MST. Pupuk kandang sapi, arang sekam, dan kompos jerami menghasilkan tinggi tanaman, jumlah anakan, bobot kering akar, panjang akar, bobot kering tajuk, dan panjang malai dibandingkan Azolla pinnata. Kombinasi pupuk kandang sapi dengan umur bibit 21 HSS menghasilkan bobot kering tajuk saat 6 MST tertinggi, sedangkan kombinasi Azolla pinnata dengan umur bibit 21 HSS dan 28 HSS menghasilkan bobot kering tajuk terendah dibandingkan perlakuan lainnya. Kesimpulan yang diperoleh pada penelitian yakni penggunaan media tanam organik berupa pupuk kandang sapi merupakan bahan organik yang efektif terhadap beberapa parameter pertumbuhan dan hasil, serta penggunaan umur bibit 21 HSS menghasilkan pertumbuhan tanaman yang lebih tinggi dibandingkan penggunaan umur bibit 28 HSS.

Abstract

Keberadaan Spodoptera frugiperda menjadi salah satu faktor pembatas produksi jagung di Indonesia. Status S. frugiperda di Indonesia sebagai hama baru pada pertanaman jagung mengakibatkan masih terbatasnya metode pengendalian yang dapat diterapkan. Pola pengendalian menggunakan pestisida sintetik akan menimbulkan permasalahan resistensi di kemudian hari. Pemanfaatan pestisida nabati dinilai sebagai sarana pengendalian alternatif yang dapat digunakan. Tanaman sirsak (Annona muricata) merupakan salah satu tanaman yang berpotensi dijadikan sebagai pestisida nabati. Pemanfaatan tanaman A. muricata di Indonesia sebagai pestisida nabati telah dilaporkan efektif untuk mengendalikan berbagai hama. Ekstrak metanol biji A. muricata diujikan dengan konsentrasi 0%, 0,2%, 0,4%, 0,8%, dan 1,6%. Berdasarkan hasil penelitian, ekstrak biji A. muricata 1,6% dinilai efektif untuk mengendalikan S. frugiperda dengan tingkat mortalitas sebesar 93,33 ± 1,15 % dan nilai LC95 sebesar 3,105%, dapat menghambat laju perkembangan larva hingga 5,85 hari, mempengaruhi keberhasilan pembentukan pupa hingga 33%, dan keberhasilan imago hingga 0%. Akan tetapi, ekstrak metanol biji A. muricata dinilai kurang efektif dalam menghambat aktivitas makan dan pertumbuhan S. frugiperda. Respons penghambatan aktivitas makan teramati hanya sebesar 32,43% dan pengaruhnya terhadap penghambatan pertumbuhan larva tidak berbeda nyata dengan perlakuan lain. Ekstrak biji A. muricata dapat digunakan sebagai alternatif pengendalian S. frugiperda namun perlu dikembangkan dengan menguji fraksi pelarut lain maupun dengan mengombinasikan ekstrak biji A. muricata dengan tanaman lain.

Abstract

This study aims to evaluate yield and yield components in several peanut lines planted in West Java, Indonesia. The genetic materials tested involved 21 genotypes consisting of 18 potential peanut lines (G100, G133, G142, G144, G199, G205, G209, G21, G234, G237, G33, G37, G41, G53, G54, G76, G84, G99) from a selection of 5 biparental population (GWS79A1/”Zebra”, “Jerapah”/GWS79A1, “Zebra”/GWS79A1, GWS79A1/”Jerapah”, “Zebra”/GWS18A1) and 3 comparative varieties (“Gajah”, “Sima”, and “Zebra”) as controls. Results showed that various genotypes have significant effects on plant height (at 9 and 10 WAP), number of branches (at 4, 10, and 12 WAP), flowering age, and harvest age. Some potential lines showed ideal characters expected of a high quality peanut plant. Based on characters such as harvest age, dry pod weight, and productivity, G100, G41, G21, G205, and G84 can be considered the best potential lines. These lines demonstrated high heritability values including characters classified as high category such as plant height, number of branches, age of flowering, age of harvest, harvest index, wet stover weight, fresh pod weight, number of filled pods, number of empty pods, number of filled pods, and weight of 100 seeds. Additionally, these lines also show high productivity, a character classified in the medium category.

Abstract

Production of pagoda mustard greens is currently still limited, while market demand is increasing. For this reason, it is necessary to increase the yield of pagoda mustard plants through hydroponic with optimization of nutrition and media. This study aimed to determine the plant responses to the application of AB Mix nutrient concentration and growing media types, as well as the effects of their interaction on the growth and yield of pagoda mustard greens. The research was conducted in June-July 2022 at a Screen House in Ciwidey, Bandung, at an altitude of 1,200 meters above sea level. The research used a factorial completely randomized design (CRD) with three replications. The first factor was the concentration of AB Mix nutrients 1,050; 1,150; and 1,250 ppm, and the second factor was the growing media rockwool, cocopeat, sponge, and rice husk charcoal. Data were analyzed using ANOVA and further tested using the Least Significant Difference (LSD) at the 5% level. The results showed that AB Mix nutrient with a concentration of 1,250 ppm or rockwool planting media was able to increase the growth and yield of pagoda mustard greens, but there was no interaction between the two treatment factors.

Abstract

Upland rice has the potential to be cultivated on land that has limited water. Plant spacing needs to be done as a strategy so that upland rice can absorb light and water optimally. Apart from that, biochar can be used to improve soil properties so that it is suitable for supporting the growth of upland rice plants on dry land. The study aims to examine the response of biochar application and plant spacing on the growth and yield of upland rice. The study was conducted in the experimental garden of the Faculty of Agriculture, Universitas Perjuangan Tasikmalaya at an altitude of 359 meters above sea level. This study used a factorial Randomized Completely Block Design (RCBD). The first factor is a type of biochar consisting of coconut shells and rice husks charcoal. The second factor is the plant spacing consisting of 20 x 20 cm and 30  x 30 cm. The results showed that there was no interaction between the two treatments on the growth and yield of upland rice. The application of biochar had a significant effect on the number of panicles per hill, while plant spacing had a significant effect on the root length, root wet weight, 1.000 seed weight, and yield. The coconut shell was able to increase the number of panicles per hill, while the wider plant spacing caused an increase in root length, root wet weight, 1.000 seed weight, and yield. In general, the application of biochar can improve crop yields, while regulating the plant spacing has the potential to increase the growth and yield of upland rice.

Abstract

Bacterial leaf blight (BLB), caused by Xanthomonas oryzae pv. oryzae (Xoo) is a significant disease attacking rice crops worldwide. This disease attacks at various stages of plant growth and causes significant yield loss. Breeding new varieties resistant to BLB is important to support sustainable agriculture in the future. This study aimed to identify new superior green super rice (GSR) lines resistant to BLB disease. The experiment evaluated the resistance of lowland rice lines obtained from anther culture using a factorial randomized complete block design. The 1st factor was genotype, consisting of 20 lines, 2 checks of commercial varieties (Inpari 42 Agritan GSR and Inpari 18), a resistant check (Conde), and a susceptible check (Taichung Native 1). The 2nd factor was BLB pathotypes (i.e., III, IV, and VIII). Quantitative data on disease severity and severity index were analyzed using analysis of variance and t-Dunnett test at 5% level. The results showed that the interaction between genotype and pathotype affected the disease severity and severity index in both growth phases. The tested lines exhibited varying resistance, from susceptible to resistant, to BLB. Four lines (SN 11, 13, 57, and 58) showed moderate to resistant criteria for BLB disease of 3 pathotypes in both growth phases. The selected lines can be used as a source of parents for breeders and candidates for new superior varieties with BLB resistance properties to support the reduction of synthetic chemical bactericide inputs and control BLB disease. However, further field evaluations are necessary to assess their performance.
