Abstract

Jagung manis merupakan komoditas penting untuk mendukung pertanian di Indonesia. Produktivitas yang rendah menjadi permasalahan yang dialami dalam usahatani jagung manis dalam negeri. Penelitian ini bertujuan untuk menduga daya gabung umum (GCA) dan daya gabung spesifik (DKT) jagung manis berdasarkan biplot GGE. Penelitian dilaksanakan di Desa Cikajang, Kecamatan Cikajang, Kabupaten Garut. Penelitian dilaksanakan mulai bulan April 2023 sampai dengan Juli 2023. Penelitian menggunakan rancangan acak kelompok dengan 40 perlakuan yang diulang sebanyak 3 kali. Hasil analisis ragam menunjukkan bahwa terdapat pengaruh nyata antara galur, penguji, dan galur x penguji terhadap karakteristik tinggi tanaman, jumlah daun, dan diameter batang. Berdasarkan analisis GGE Biplot, pola biplot GGE “mean vs stability” mengidentifikasi daya gabung umum (GCA). Terdapat 7 galur yang memiliki GCA baik  ditinjau dari tinggi tanaman dan jumlah daun. Pola biplot GGE “Yang Menang Di Mana/Apa” mengidentifikasi kemampuan menggabungkan khusus (SCA). Ada 2 kombinasi persilangan galur x penguji yang memiliki SCA terbaik untuk tinggi tanaman, jumlah daun, dan diameter batang. Kata Kunci : Daya Gabung, GGE Biplot, Jagung Manis, Vegetatif

Abstract

The demand for long bean plants is still quite high among the public, but the production of long bean plants is decreasing every year. This research aims to determine the growth and production of long bean plants when given various types of compost and NPK Mutiara 16:16:16. This research used a Completely Randomized Design (CRD) of 2 factors, the first factor was Providing Various Types of Compost Fertilizer (corn litter, banana peels, cassava peels and pineapple peels) and the second factor was NPK Mutiara 16:16:16 (0 kg/ha, 100 kg/ha, 200 kg/ha, 300 kg/ha). The variables observed were Net Assimilation Rate, Relative Growth Rate, flowering age, harvest age, number of pods, pod weight and pod length per plant. The results of the research showed that the combination of pineapple peel compost and NPK Mutiara 16:16:16 could increase the growth and production of long bean plants compared to other treatments. Providing compost or NPK Mutiara 16:16:16 fertilizer alone does not improve all observed parameters on the growth and production of long bean plants.

Abstract

The decrease in rice production due to bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo) has been reported to be quite high, ranging from 15–23%. Based on its spread and rice losses due to this pathogen, efforts are highly needed to reduce and control it. The BLB resistance gene is called the Xa gene. Currently, there are 42 Xa genes controlling BLB resistance that have been identified in some cultivars, mutant population and wild species of rice. The Xa3, Xa4 and xa8 genes are the three well-known of bacterial leaf blight resistance genes in hybrid rice in China and South Asian countries. Considering their dominant existence in Indonesia, molecular screening by means of PCR detection has been done in eight families of F7 Sintanur x PTB33 and two families of F5 Pandanwangi x PTB33 for these three Xa genes. Molecular markers BB3RF, BB3RR, MP1, MP2, and RM21044 were applied to detect those three genes. Based on DNA visualization it was found that SP101-3-1-5-8, SP101-3-1-19-26, SP101-3-1-38-4, SP87-1-1-7-7, PP48-5-1, and PP48-5-24 had the Xa3 gene. The genotypes that carry the Xa4 gene were SP101-3-1-19-27, SP101-3-1-38-4 and SP101-3-1-38-25. Meanwhile, the xa8 gene was only detected in Pandanwangi, meanwhile the SP101-3-1-38-4 carried the Xa3 and Xa4 genes. No genotypes were found with three genes. The selected genotypes will be further developed in order to assembly multiple resistance genes for this particular disease.

Abstract

Rainfed rice fields are wetlands whose use is still not optimal, so proper management is needed so that they can be utilized for rice cultivation. In efforts to improve land productivity, the concept of a sustainable rice cropping system has been developed which takes into account environmental conditions known as the System of Rice Intensification (SRI). One of the serious limiting factors in the utilization of rainfed lowland rice fields is the problem of weeds. This study aims to determine the diversity of weeds in rainfed paddy fields planted with aromatic rice and fertilized with NPK fertilizer combined with rice straw compost. This study used a 2-factor randomized block design (RBD). The first factor was the dose of NPK fertilizer (A), namely: a0 = 0 kg ha-1 (control), a1 = 150 kg ha-1, and a2 = 300 kg ha-1, and the second factor is the dose of rice straw compost (K), namely: k1 = 5 t ha-1, k2 = 7.5 t ha-1, k3 = 10 t ha-1, k4 = 12.5 t ha-1, k5 = 15 t ha-1, and k6 = 20 t ha-1. The results showed that there were six types of weeds found in the aromatic rice planting area in rainfed lowland rice fields that were applied with NPK fertilizer and rice straw compost, namely Cyperus rotundus, Chloris radiata, Cyperus iria, Echinochloa colona, Ludwigia palustris, and Amaranthus spinosus. The weed that dominated rainfed lowland rice planted with aromatic rice with the application of NPK fertilizer and rice straw compost was Cyperus rotundus, with a summed dominance ratio (SDR) of 58–100% found in the a2k6 treatment (300 kg ha-1 NPK + 20 t ha-1 rice straw compost). The highest weed diversity index (H') value was found in the a0k1 treatment (0 kg ha-1 + 5 t ha-1 rice straw compost) at a 45 DAP of 1.10.

Abstract

Water guava (Syzygium aqueum Burm.) ‘Citra’ is one of Indonesia's native fruits that is much in demand by the public because of its crispy flesh, sweet taste, high water content, high economic value, and has no seeds. Efforts to maintain the superior nature of these plants can be done by vegetative propagation, among others by cuttings. Efforts to increase the success of cuttings can be done using auxin with the right concentration to induce root growth. This study aims to determine the growth of water guava (Syzygium aqueum Burm.) ‘Citra’ cuttings on various auxin sources. The research was conducted from March 2024 to May 2024 at the Experimental Garden of IPB Tropical Horticulture Study Center, South Bogor District, West Java. This study used a completely randomized design (CRD) with a single factor consisting of six levels, namely control, 1000 ppm IBA, 1000 ppm NAA, a combination of 1000 ppm IBA + 1000 ppm NAA, 200 ppm Rootone-F, and 50% shallot extract. The results showed that the 50% shallot extract treatment was the best in shoot emergence time, number of shoots, shoot length, and number of leaves, but not significantly different from the 200 ppm Rootone-F treatment. The best 1000 ppm IBA + 1000 ppm NAA treatment on the most roots.

Abstract

Porang (Amorphophallus muelleri Blume) is an agricultural commodity with increasing export value; however, its production is limited by challenges in propagation. Bulbil propagation is considered the most effective method, but it is hindered by a dormancy period that prolongs the growth process. One potential solution is the application of cytokinin-type plant growth regulators, such as Benzyl Amino Purine (BAP). This study aimed to determine the optimal combination of BAP concentration and soaking duration to stimulate shoot growth in porang bulbils. The experiment was conducted from September to November 2023 at the Agronomy and Agrostology Laboratory and the UIN Agriculture Research and Development Station (UARDS) screen house, Faculty of Agriculture and Animal Science, Universitas Islam Sulthan Syarif Kasim Riau. A Completely Randomized Design (CRD) with two factors was used: BAP concentration (0, 50, 100, and 150 mg/L) and soaking duration (1, 2, and 3 hours), with three replications. Observed parameters included germination capacity, time to shoot emergence, shoot length, number of shoots, and percentage of rooted shoots. Results showed that the combination of 150 mg/L BAP and 3 hours of soaking produced the best outcomes in terms of germination capacity (100%), time to shoot emergence (21 days), shoot length (34.2 cm), and number of shoots (205). The highest percentage of rooted shoots (59.1%) was observed with a BAP concentration of 50 mg/L, while the best soaking time for rooting (56.7%) was 1 hour. In conclusion, the most effective treatment for promoting porang bulbil sprouting was 150 mg/L BAP with a soaking duration of 3 hours.
