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

Bawang merah (Allium ascalonicum L.) merupakan komoditas strategis di Indonesia. Kebutuhan yang terus meningkat sehingga produksinya perlu ditingkatkan. Faktor penentu produksi diantaranya adalah jarak tanam dan pemupukan. Tujuan dari penelitian ini adalah menentukan jarak tanam dan dosis pemupukan NPKMg yang tepat untuk tanaman bawang merah. Percobaan disusun secara faktorial dalam Rancangan Kelompok Lengkap Teracak dengan 3 ulangan menggunakan varietas SS-Sakato. Faktor pertama adalah jarak tanam yaitu 10 cm x 10 cm, 10 cm x 15 cm, 15 cm x 15 cm, dan 15 cm x 20 cm. Faktor kedua adalah dosis pupuk NPKMg (10:12:17:2) yaitu 200, 400, 600, dan 800 kg ha-1. Jarak tanam 10 cm x 15 cm menghasilkan luas daun, jumlah umbi dan bobot basah umbi per rumpun, hasil ubinan dan produktivitas lebih tinggi dibandingkan jarak tanam 10 cm x 10 cm, 15 cm x 15 cm, dan 15 cm x 20 cm. Laju transpirasi tertinggi juga dihasilkan dari jarak tanam 10 cm x 15 cm untuk semua dosis pupuk NPKMg (10:12:17:2), kecuali 400 kg ha-1. Peningkatan dosis pemupukan pada rentang 200 - 800 kg NPKMg (10:12:17:2) tidak meningkatkan pertumbuhan dan hasil umbi karena kandungan N rendah (20 – 80 kg ha-1) sehingga perlu tambahan pupuk tunggal sumber N. Kata kunci: bobot umbi, jumlah umbi, NPKMg, SS-Sakato

Abstract

Benih cabai memiliki banyak keragaman dan merupakan salah satu kunci keberhasilan dalam budidaya. Identifikasi keragaman benih cabai, pengujian viabilitas benih diperlukan sebagai langkah dalam perakitan varietas dan penyediaan benih bermutu. Penelitian bertujuan memperoleh informasi bentuk biji, tonjolan paruh, bobot 1000 biji dan viabilitas benih. Penelitian dilakukan terhadap 63 genotipe cabai dari 5 spesies (Capsicum annuum, C. frutescens, C. chinense, C. baccatum, dan C. pubescens) bulan Februari-Juli 2023 di Laboratorium Ilmu dan Teknologi Benih IPB, menggunakan rancangan kelompok lengkap teracak 3 ulangan. Pengamatan meliputi sifat morfologi dan fisiologi benih cabai. Biji cabai secara umum berwarna putih kekuningan dengan tonjolan paruh, kecuali C. pubescens (warna biji hitam, tidak ada tonjolan paruh), bentuk biji seperti ginjal (C. annuum), lonjong (C. baccatum), tetes air mata (C. frutescens), berbentuk D (C. pubescens), melingkar dengan mulut ikan (C. chinense). Spesies cabai yang diamati memiliki berbagai ukuran bobot 1,000 biji (ringan (<3.90 g), sedang (3.90-5.68 g), dan berat (>5.68 g). Keragaman genetik perkecambahan, potensi tumbuh maksimum, indeks vigor, kecepatan tumbuh, keserempakan tumbuh berkategori luas, sedangkan bobot kering kecambah normal, laju pertumbuhan, bobot 1000 biji berkategori sempit. Ukuran biji tidak mempengaruhi persentase perkecambahan benih. Spesies C. pubescens memiliki karakteristik benih yang berbeda dengan spesies Capsicum lainnya, sedangkan spesies C. annuum memiliki kemiripan dengan C. frutescens, C. chinense, dan C. baccatum. Kata kunci: benih, cabai, keanekaragaman, morfologi, spesies

Abstract

Corn is a strategic commodity in Indonesia's agricultural and economic development. The problem of corn production can be overcome with proper usage of nitrogen fertilization. Dynamic modeling can be used as a tool to solve this problem. This study aimed to develop a dynamic model for the growth and nitrogen uptake of composite and hybrid corn varieties. Stages in the model construction: (1) identifying system components, (2) model construction, (3) simulation, and (4) validation. The growth model is a construction of the plant's ecophysiological response to solar radiation and temperature in photosynthesis. A growth model in composite and hybrid corn varieties with simulated dry weight as output has been constructed validly. The model input components, such as light use efficiency, extinction coefficient, specific leaf area, and carbohydrate partition coefficient varied at each development phase for each variance. The actual total dry weight on the Pioneer 27 variety was 6,406 kg ha-1 with a simulated total dry weight was 6,228 kg ha-1, and the actual total dry weight on the Bisma variety was 5,127 kg ha-1 with a simulated total dry weight was 4,864 kg ha-1. The level of validity of the Pioneer 27 variety growth model reached 83.5% and the Bisma variety reached 80%.

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

Melon (Cucumis melo L.) is a high-value horticultural commodity with an increasing market demand. This condition requires the availability of high-quality seeds to support optimal productivity and fruit quality. Therefore, a rapid, accurate, and non-destructive method for seed characterization is needed to support seed quality assesment. This study aimed to characterize Salfa F1 hybrid melon seeds using a digital imaging approach and to evaluate their morphophysiological characteristics  based on imbibition, germination, and vigor. The research was conducted at the Seed Biology and Reproduction Laboratory, Department of Agronomy and Horticulture, IPB University, from September to November 2025. The results showed that Salfa F1 melon seeds exhibited relatively homogeneous morphological characteristics based on  area, perimeter, and shape parameters (circularity, aspect ratio, and solidity). The imbibition pattern showed a nonlinier  response over time, with the qubic regression model providing a high level of fit to the observed data. In line with the imbibition pattern, the high germination percentage and vigor index indicated good physiological testing can provide complementary information for characterizing the morphophysiological quality of Salfa F1 melon seeds.
