Abstract

Rice is a staple food for most of Asian, especially for Indonesian people. Population growth has been increasing every year while farmlands decreased driving farmers to convert sub optimum fields to agricultural land. This research was conducted to study performance of 4 rice varieties planted in 2 environmental conditions (wet and dry) at Sawah Baru Screenhouse, IPB Dramaga, using Randomized Complete Block Design with 2 factors; 4 rice varieties namely Jatiluhur, Mentik Wangi, IR64 and Way Apo Buru with 2 levels of environments and 3 replications. Way Apo Buru showed relatively constant values in number of panicle (8.7 in wet to 8.3 in dry), and IR64 showed relatively constant values in grain weight per panicle in both environments (3.2 g in wet to 3.1 g in dry). Jatiluhur as an upland rice showed the best values in plant height (99.83 cm), grain weight per panicle (9.59 g) and total grain per panicle (185.67). ABSTRAKPadi merupakan bahan makanan pokok bagi sebagian besar penduduk Asia, khususnya masyarakat Indonesia. Pertumbuhan penduduk yang semakin meningkat setiap tahunnya dan semakin sempitnya lahan pertanian mendorong para petani untuk memaksimalkan produksi padi melalui pemanfaatan lahan marginal sebagai lahan pertanian. Penelitian ini dilakukan untuk membandingkan 4 varietas padi yang ditanam pada kondisi lingkungan optimum dan lingkungan yang memiliki cekaman kekeringan. Penelitian ini dilaksanakan di Screenhouse Sawah Baru IPB Dramaga dengan menggunakan Rancangan Kelompok Lengkap Teracak dengan 2 faktor, yaitu varietas (Jatiluhur, Mentik Wangi, IR64 dan Way Apo Buru) dan kondisi lingkungan dengan 3 ulangan. Way Apo Buru menunjukkan nilai yang relatif konstan pada karakter jumlah anakan (8,7 pada lingkungan basah sampai 8,3 pada lingkungan kering), dan IR64 menunjukkan nilai yang relatif konstan pada karakter bobot benih per malai (3,2 g pada lingkungan basah sampai 3,1 g pada lingkungan kering). Jatiluhur yang termasuk dalam varietas padi gogo menunjukkan keunggulan pada karakter vegetatif tinggi tanaman (99,83 cm), karakter generatif bobot gabah per malai (9,59 g) dan jumlah gabah total per malai (185,67 butir) dalam dua kondisi lingkungan.

Abstract

The Community Engagement Program (PPM) organized by the Seed Industry Technology Study Program, Vocational School of IPB University, aims to address the challenges faced by the Women Farmers Group (Kelompok Wanita Tani, KWT) Ciharashas in Mulyaharja Village through training on vertical hydroponic techniques. This program encompasses problem identification, training, and optimizing greenhouse facilities. Problem identification revealed key issues such as greenhouse facility damage and the limited knowledge of KWT members regarding modern cultivation techniques. The training focused on vertical hydroponic system installation, nutrient management, and plant maintenance, emphasizing the efficient use of limited land. The greenhouse was repaired to support sustainable production and serve as a training hub. The training outcomes showed significant improvements in the understanding and skills of KWT members, as evidenced by pre-test and post-test results. Members are now capable of optimizing their yards, producing high-quality harvests, and increasing income through better marketing strategies. Post-training monitoring indicated the sustainability of the vertical hydroponic activities, with KWT members actively continuing the project independently. This program successfully created long-term positive impacts, including community empowerment, increased productivity, and sustainable agricultural solutions relevant to urban communities.

Abstract

Water is an important factor for plant growth. A few studies about the amount of water required by the seed for radicle emergence in germination has been done. This research was conducted at the Laboratory of Seed Science and Technology, Faculty of Agriculture IPB Bogor. Maize seeds were planted using a solution of Polyethylene Glycol (PEG) 6000 with a concentration level of 0%, 5%, 10%, 20%, and 30%. A Completely Randomized Design with 3 replications was used in this research. The appearance of the radicle first occurred in phase II, namely during the 48-hour observation for the Ψ -0,13 MPa treatment (5% PEG) and 60 hours for the Ψ -0,4 MPa treatment (10% PEG). The results showed that testing maize seed vigor under drought stress can use water potential (Ψ) higher than -0,4 MPa. The results showed that water potential (Ψ) of -0,4 MPa or higher can be used in vigor testing of maize seed.

Abstract

Maize is a significant food crop consumed in numerous countries worldwide. Increasing the yield potential of maize can be achieved through the breeding of high-yielding hybrid varieties. The objectives of this study were to assess the performance of hybrid means and parent combining ability for grain yield and other agronomic traits using a line x tester mating design. The study took place at the Gunung Gede Experimental Station of IPB University, Bogor, from June to October 2022. The experiment was conducted using a randomized complete block design with a single genotype factor and three replications. Twenty-two hybrids were utilized as genetic materials, including 20 hybrid candidates and two check varieties. Six maize lines (H1, L26, Nei, P2B, and P42) were employed as line parents, while L15 and P10 were used as tester parents in the line x tester analysis. The neighbor-joining tree analysis indicated that the female parent has a significant influence on the agronomic and yield performance of the hybrids. Correlation analysis revealed that the yield is more strongly influenced by ear diameter rather than ear length, and it is more affected by the number of kernel rows than the number of kernels per row. Three selected hybrids with favorable traits were Nei x B1, L15 x L26, and L26 x P10. The parent L26 demonstrated relatively good general combining ability for yield and may be considered for future maize breeding program.

Abstract

ABSTRACTDrought has become a main barrier of rainfed rice in dry climate and short wet season areas. Growing drought-tolerance varieties is a practical approach to minimize yield lost of rice by the drought stress condition. The aims of this research were to examine the inheritance of drought tolerance character, to identify selection traits, and to estimate genetic gain for drought tolerant on lowland rice. Four rice varieties, i.e., Jatiluhur, Mentik Wangi, IR64, Way Apo Buru, were fully diallel crossed. The parent varieties and the F1’s were grown at Sawah Baru, Dramaga experimental field in two irrigation treatments, optimum and sub optimum where irrigation was applied until three weeks after transplanting. A randomized complete block design with three replications for each irrigation treatment was applied to the experiment. The results showed that there is a significant maternal effect on tiller number. The values of additive variance were higher than the dominance for all other characters except tiller number and grain weight per plant. The highest value for narrow sense heritability was achieved by panicle length.Keywords: diallel, drought, genetic, rice

Abstract

Suboptimal environmental conditions cause low imbibition rate in maize plants, thus disrupting enzyme activation and food availability for the sprouts, and inhibiting the germination process. This study aims to provide a better understanding of the imbibition pattern and physiological characteristics of germination, hopefully obtaining useful information in the development of seed processing techniques and more efficient agricultural technology. The maize seeds used in this study were the seeds of four maize varieties. The imbibition pattern was obtained by weighing the seeds from 0 to 120 hours with a 6-hour time interval. The results showed that the four varieties showed a typical three-phase imbibition pattern with almost the same time. Overall, the highest seed growth and germination was found in Jantan F1 and Paramita, which have great potential for use in seed propagation, while Baruna variety showed low seed quality and needs further evaluation for improvement.

Abstract

Research on breaking seed dormancy in rice is essential for understanding dormancy-breaking methods and their persistence, as dormancy behavior varies among rice varieties. This study aimed to examine the persistence of dormancy and effective dormancy-breaking methods in Oryza sativa L. cv. Sintanur. The research used two seed lots of the Sintanur variety—new and old lots—arranged in a split-plot design with two factors: dormancy-breaking treatments (control, 24-hour hydration, 48-hour hydration, KNO₃ solution, and GA₃) and storage periods (0, 1, 2, 3, and 4 weeks after harvest). The results showed that seeds of the Sintanur rice variety exhibited dormancy with persistence up to 3 weeks. The interaction between dormancy-breaking treatments and storage period significantly affected germination percentage, normal seedling growth, and seedling dry weight. Treatment with 10 ppm GA₃ for 48 hours effectively broke seed dormancy in the Sintanur variety starting from 1 week after harvest.
