Abstract

Mustard greens (Brassica rapa L.) is a vegetable crop that is widely consumed by Indonesians. The use of quality seeds can increase productivity. The quality of seeds can decrease during the storage period. The process of quality degradation is a natural and unavoidable process. One method of artificially fast aging of the seeds is by electrocuting the seeds using chemicals. Depression of seeds with alcohol can be used to test the deterioration of seeds due to poisoning caused by alcohol. This study aims to influence the ethanol / alcohol concentration and the duration of agitation on the viability of caisin seeds. This study used a factorial treatment design (2x5) in a completely randomized design (CRD) with four replications. The first factor is the concentration of ethanol (20% and 25%) and the second factor is the duration of the stroke (30, 60, 90, 120, and 150 minutes). The results showed that the ethanol concentration and the calming time had a significant effect on the viability of the caisin seeds. The viability of caisin seeds decreased to 45.5% with ethanol pressure for 150 minutes at a concentration of 20%.

Abstract

Quality soybean seeds are one of the essential factors to support soybean production. One of the obstacles in providing quality soybean seeds was the physiological quality of soybean seeds declined speedily during storage, especially in open storage. This study aimed to evaluate the physiological quality of yellow soybean seeds during a six-month storage period. This research was carried out from October 2020 to March 2021 in the seed analysis laboratory of the Seed Technology Study Program, Lampung State Polytechnic. The study used a Split-Plot Completely Randomized Design (CRD) with four replications. The main plot was the seed storage period which consists of seven levels, specifically 0, 1, 2, 3, 4, 5, and 6 months. Sub-plots were soybean variety which consists of two levels, specifically  Dega variety and Deja variety. The results of the study indicated that (1) Deja variety had higher physiological quality than Dega variety based on germination, vigor index, growth speed, growth, maximum growth potential, and seed moisture content during the six-month storage period (2) Deja variety had longer storability than Dega variety in open storage.Keywords: Soybean, Physiological quality, Open storage.

Abstract

One of the essential factors in crop production is the use of quality seeds. The availability of quality seeds affects the quality and yield. Currently, in the field is that soybean seeds sold by seed stores are seeds that have deteriorated and are stored in unfavorable conditions, causing the quality of the seeds to decline. To continue planting, a technique for improving the performance of soybean seeds is required through matrix conditioning and fertilization. This study aimed to determine the effect of matrix conditioning and fertilization treatment on increasing the growth of soybean seeds stored for two months. This study used a two-factor completely randomized design (CRD) with three replications. The first factor was matrix conditioning media (without matrix conditioning, sawdust, and husk charcoal). The second factor was fertilization (without organic fertilizers and inorganic fertilizers), 100% organic fertilizers, 100% inorganic fertilizers, and 100% organic fertilizers + 50% inorganic fertilizers). The data were tested by using 5% BNT. Variables observed were plant height, number of leaves, leaf dry weight, stem dry weight, root dry weight, and number of root nodules. The results showed that there was an interaction effect between matrix conditioning and fertilization media on the observed variables of plant height, leaf dry weight, and single matrix conditioning treatment that affected the observed variables of root dry weight and number of root nodules in improving seed quality and growth. Keywords: soybean, quality, matrixconditioning, fertilization

Abstract

Pure line selection is carried out in watermelon plant breeding programs to produce hybrid varieties with certain advantages and uniqueness that are different from other watermelon varieties. The aim of the research was to test the yield of F1 hybrid watermelon resulting from a selection of pure line parental crosses on lowland land (Seed Teaching Farm-Lampung). The research used six selected hybrid watermelon genotypes and four hybrid (commercial) variety genotypes as comparison varieties. The experimental design used was a Randomized Block Design (RAK) with further testing using Duncan's multiple range test at the 5% level. The research results showed that the WM 2210-0616 genotype had the highest production yield, namely 17.14 t.ha-1 compared to other genotypes. Watermelon genotypes that have the potential to be registered as new superior varieties include WM 2210-0616; WM 2210-1011; WM 2210-0608; and WM 2210-0401. These four genotypes have advantages in fruit weight, skin color, fruit shape, sugar content, and resistance to breaking during transportation. These advantages are attractive to consumers in developing hybrid varieties in the lowlands area.

Abstract

Penggunaan benih bermutu menjadi kunci utama dalam sistem budidaya tanaman. Oleh sebab itu, pemulia tanaman terus melakukan inovasi untuk menghasilkan benih baru yang bermutu dengan karakteristik dan daya hasil yang banyak diminati oleh petani. Rondo Nunut adalah salah satu benih padi lokal yang saat ini sudah sampai pada tahap pemurnian varietas dan akan diajukan untuk pelepasan varietas baru. Tujuan dari penelitian ini yaitu mengetahui larutan ZPT alami dan lama waktu perendaman yang efektif digunakan untuk pematahan dormansi benih padi lokal Rondo Nunut dengan masa simpan 7 hari setelah panen, serta mengetahui interaksi antar perlakuan yang dicobakan. Penelitian ini menggunakan Rancangan Acak Lengkap dua faktor dengan 3 ulangan. Faktor pertama yaitu larutan perendaman (aquades, air kelapa muda, ekstrak bawang merah, air cucian beras, dan KNO3) dan faktor kedua yaitu lama waktu perendaman (24 jam dan 48 jam). Variabel pengamatan yang dilakukan yaitu daya berkecambah, kecambah abnormal, benih segar tidak tumbuh, indeks vigor, potensi tumbuh maksimum, panjang plumula, panjang radikula, panjang kecambah, dan berat basah kecambah. Hasil penelitian menunjukkan bahwa perlakuan perendaman benih padi menggunakan aquades, larutan air kelapa muda, ekstrak bawang merah, air cucian beras dengan konsentrasi 50%, dan larutan KNO3 3% selama 24 jam dan 48 jam tidak efektif digunakan untuk pematahan dormansi benih padi lokal varietas Rondo Nunut dengan masa simpan 7 HSP.  Ketidakseimbangan hormonal diduga menjadi salah satu penyebabnya.
