Bayam termasuk salah satu sayuran terpenting di Indonesia karena paling banyak dikonsumsi setelah kangkung. Bayam hijau dan bayam merah merupakan jenis bayam paling banyak ditanam dan dikonsumsi. Penelitian ini bertujuan untuk mengetahui perbedaan pertumbuhan dan produktivitas varietas bayam hijau dan bayam merah. Penelitian dilakukan pada Februari – April 2021 di Kebun Percobaan Leuwikopo, Departemen Agronomi dan Hortikultura, Fakultas Pertanian, IPB University. Sebanyak 9 varietas bayam hijau (Maryland, Richie, Maestro, Benua, Doly, Khanafiah, Manila, Pacific, White Leaf) dan 4 varietas bayam merah (Mira, Baret Merah, Clara, Aurora) ditanam menggunakan rancangan kelompok lengkap teracak dengan tiga ulangan. Hasil penelitian memperlihatkan bahwa varietas bayam hijau memiliki kandungan persentase warna hijau daun lebih banyak namun memiliki persentase warna biru dan merah yang lebih rendah dibandingkan varietas bayam merah. Hasil penelitian juga memperlihatkan bahwa varietas bayam hijau menghasilkan tinggi tanaman dan produktivitas yang lebih baik dibandingkan varietas bayam merah, namun varietas bayam merah menghasilkan luas daun dan jumlah daun per tanaman saat panen yang lebih baik besar dibandingkan varietas bayam hijau. Varietas White Leaf merupakan varietas bayam yang sangat baik karena memiliki persentase warna hijau daun yang tinggi, luas daun yang besar dan produktivitas yang tinggi. Spinach is one of the most important vegetables in Indonesia because it was the second most consumed after kangkung. Green spinach and red spinach are the most widely grown and consumed types of spinach. This study aimed to determine differences in growth and productivity between varieties of green spinach and red spinach. The research was conducted in February – April 2021 at the Leuwikopo Experimental Field, Department of Agronomy and Horticulture, Faculty of Agriculture, IPB University. A total of nine varieties of green spinach and four varieties of red spinach were planted using a completely randomized block design with three replications. The results showed that the green spinach variety contained a higher percentage of green leaf color but had a lower percentage of blue and red leaf color than the red spinach varieties. The results also showed that the green spinach varieties produced better plant height and productivity than the red spinach varieties, but the red spinach produced better leaf area and a number of leaves per plant at harvest than the green spinach. The White Leaf variety is the excellent spinach variety because it has a high percentage of green leaf color, large leaf area, and high productivity.

Abstract

Program pemuliaan tanaman dapat lebih efektif dan efisien jika terdapat informasi pewarisan sifat dari karakter yang akan dimuliakan. Namun, belum semua karakter kualitatif pada buah tomat diketahui pola pewarisan sifatnya. Penelitian ini bertujuan untuk memperoleh informasi tentang pewarisan sifat beberapa karakter kualitatif pada tanaman tomat. Penelitian ini dilakukan pada Januari – April 2020 di Kebun Percobaan IPB Leuwikopo, Bogor, Indonesia. Sebanyak 10 tanaman varietas Tora IPB, 10 tanaman genotype GIK serta 10 tanaman F1 (hasil persilangan Tora IPB x GIK) digunakan pada penelitian ini. Selain itu, juga digunakan sebanyak 185 tanaman populasi F2 (hasil selfing F1 Tora IPB x GIK) pada penelitian ini. Analisis data dilakukan menggunakan uji khi kuadrat dilakukan pada populasi F2 untuk menentukan rasio segregasi karakter kualitatif yang paling tepat. Hasil pengamatan menunjukkan bahwa karakter posisi anak daun terhadap tangkai daun, bentuk ujung buah tomat, tinggi kelopak terhadap mahkota, dan karakter luas plasenta buah tomat dikendalikan oleh 2 gen dengan 2 alel per lokus. Tipe intraksi gen pada pewarisan karakter posisi anak daun terhadap tangkai daun dan bentuk ujung buah tomat yaitu epistasis dominan, sedangkan tipe interaksi gen pada pewarisan karakter tinggi kelopak terhadap mahkota dan karakter luas plasenta buah tomat berturut-turut adalah epistasis dominan ganda dan semi epistasis. Karakter green shoulder pada buah tomat dikendalikan oleh 1 gen dengan 2 alel per lokus. Gen pengendali karakter green shoulder bersifat dominan terhadap karakter tanpa green shoulder (polos) pada buah tomat.

Abstract

Depolarized katuk pellets (Sauropus androgynus) as a growth trigger in ruminants have been produced, but are constrained by the adequacy of leaf raw materials. This study aims to utilize the soft stems (BL) of the katuk plant as a substitute for leaf raw materials (D) as much as 15%, and its effect on the productvitas of rams growing. Katuk leaf pellets (100%) and pellets mixed between D (85%) and BL (15%) or DBL, were prepared through a depolarization process. The male rams (21) were divided into 7 groups, 3 heads each, with different pellet-giving treatments. The treatment was the control group, leaf pellets 5 g (D-5), 10 g (D-10), and 15 g (D-15), and also the DBL pellet group 5 g (DBL-5), 10 g (DBL-10), and 15 g (DBL-15) per head daily. Each sheep gets adequate treatment and feed for 3 months. TheDBL-15 and D-15 sheep group showed an improvement in the average percentage of growth in sheep body weight and carcass (p<0.05), which were 54% and 43%, respectively, as well as 74% and 43%, compared to the control group, which was only 46% and 40%. The application of DBL-15 pellets showed a greater percentage of fat deposits, which was 3.4% (p<0.05) than the administration of D-15 pellets, which was only 2.4% and the control group (2.1%). It was concluded that the 15% soft stem to the pellets is still very good as a substitute for the raw material of katuk leaves for the production of depolarized pellets.

Abstract

Performance is one of the important stages in breeding sweet corn before releasing varieties. Performance evaluation is carried out to determine the phenotypic character of a genotype so that the yield potential of a variety can be known. Research on the performance of sweet corn in Indonesia is still relatively rare, so this research needs to be carried out with the aim of knowing the performance and yield of 23 commercial sweet corn varieties (Zea mays saccharata Sturt) in Indonesia. The study was carried out at the Leuwikopo Experimental Garden, Dramaga, Bogor from August to November 2021 using one factor, namely varieties with a complete randomized group design with three replications. The results of analysis of variance on 23 varieties of sweet corn showed that the genotype had a very significant effect on the characters of plant height, cob height, age of female flower emergence, anthesis silking interval, cob length, sweetness level, shelf life and cob weight, both with and without husks. weight per plot, and sweet corn crop productivity. In addition, the genotype had a significant effect on the length of the cob stalk and had no significant effect on the character of the stem diameter, the diameter of the cob, and the length of the seed cob. The varieties with the best productivity were found in the Talenta variety. In addition, observations of each observed character indicate the advantages and disadvantages of the tested varieties.Keywords: genotype, yield, character, performance, productivity

Abstract

Chili (Capsicum annuum L.) exhibits a wide range of variations in terms of crown shape, fruit shape, fruit color, leaf color, leaf shape, and taste. While chili is commonly known as a food plant, it also serves as an attractive ornamental plant. Specifically, ornamental chili plants are desired to possess specific traits, such as compact growth, high fruit yield, and a variety of fruit colors within a single plant. This study aims to comprehensively describe the quantitative and qualitative superiority of the Nazla IPB variety in terms of its characteristics. The research was conducted in the Leuwikopo Darmaga experimental garden's greenhouse, located in Bogor, utilizing a randomized complete block design with four replications. The Nazla IPB variety, which is an open-pollinated (OP) cultivar, stands out due to its short plant height, ranging from 17.83 to 26.42 cm, making it highly suitable for ornamental purposes. Furthermore, the chili plants of the Nazla IPB variety possess a compact crown shape, enhancing their visual appeal, coupled with their short stature (ranging from 21.83 to 26.69 cm). The primary distinguishing features of the ornamental chili variety Nazla IPB include: 1) the color of the leaves, which transition from green (Green 137 C) to purple (Purple N186 A); 2) the black color of the young chili fruit (Black 203 A); 3) the fruit shape of Nazla IPB, which can be described as moderately triangular; and 4) the fruit undergoes a color transformation from black to dark green and finally to red. Nazla IPB has potential to serve as an attractive decorative plant option.

Abstract

Increased phenotypic diversity is needed to increase the economic value of Aglaonema. However, information on increasing phenotypic diversity of Aglaonema using gamma-ray irradiation has not been widely known. This study aimed to investigate the effect of gamma ray irradiation treatment to the performances of two varieties of Aglaonema. This research was arranged factorially using randomized group design (RKLT) of two factors consisting of 8 combinations of treatments that are 4 level of irradiation dose and 2 Aglaonema varieties. The results showed that the induction of gamma ray irradiation decreased the % viable of the plants, the number of leaves, leaf length, leaf width, and the % green color as well as increased the % blue on the leaves of Aglaonema Butterfly and Aglaonema Siam Aurora. The interaction between dose of irradiation and aglaonema varieties was obtained in the % red of leaf color. Both of Aglaonema varieties had a high radiosensitivity with LD50 values ranged of 16.70 - 17.14 Gy

Abstract

The selection of shade-tolerant sweet corn under intercropping conditions is necessary to provide adaptive superior cultivars for agroforestry systems. Until recently, there have not been many reports of superior varieties of sweet corn tolerant to low light. This study aimed to determine the differences in the morphological, physiological and production responses of 25 hybrid sweet corn genotypes to low light intensity. This study used a nested design with three replications. The factors tested were the shade level (0%, 25%, 50% and 75%) and the genotype of hybrid corn. The results showed that most of the hybrid corn genotypes tested showed an increase in production at 25% shade, while at 50% and 75% shade, they showed a decrease in production. Based on relative production at 25% shade, the genotypes can be split into three groups: sensitive, moderate and tolerant. The tolerant genotype including F1 T8-2A x SM12-2 (G6); Exotic (G13); Talenta (G15); Golden boy (G16); F1 SM12-2 x T9-2 (G20) provided the highest increase in morpho-physiological characters and yields compared to the moderate and sensitive. In all genotype groups, morphological variables (number of leaves, leaf area, stem diameter and relative growth rate), physiological variables (stomata conductance, photosynthetic rate, and total dissolved solids (TDS)), and yield variables (length, diameter, number, weight and unhusked weight of ears) were significantly higher in the no-shade than in the shaded conditions. These findings can be used as a basis for sweet corn planting recommendations under shade condition areas such as in agroforestry systems.
