Abstract

Mango (Mangifera indica L.) can be developed through plant propagation by the method of shoot-tip grafting. The problem that often take place is the distance between the mother tree and the location of the connection that is far apart, so it takes a long time and is tough to finish within one day. This research aims to obtain a combination of shelf life and types of scion wrapping materials on the growth of mango seedlings. The research conducted in April - August 2023 at UPT Horticultural Seed Development using Complete Randomized Design (CRD) with 2 factors 3 replications. The first factor is storage time (L) (0 days, 2 days, 4 days, and 6 days) and the second factor is the type of wrapping materials (M) (without packaging, banana frond wrapping, newspaper wrapping, and coconut husk wrapping). Parameters include the time at which shoots appear, the percentage of viable grafting, the length of the shoots and the total number of leaves. The results showed that in general the percentage of success was 70%. The treatment of storage time and type of entres wrapper did not affect the percentage of live grafting, but at a storage time of 2 days, the fastest results were obtained at the time of bud emergence and the longest results in bud length. Keywords: Entry, Length of Storage, Type of Wrapping, Mango Shoot Grafting

Abstract

Orchid plantlets are expected to be able to adapt and grow under optimal conditions during the acclimatization period. Selecting appropriate planting media and providing proper nutrition is one of the efforts that can be made to increase the success of high growth of Dendrobium, sp orchid plantlets during the acclimatization period. The aim of this research was to identify the appropriate planting medium and concentration of rooting starter solution to support the growth of Dendrobium sp orchid plantlets during acclimatization. This research was carried out from March to July 2022 at the Bangka Belitung University Experiment and Research Garden. This study used a factorial randomized block plan. The first factor is the planting medium; (M1) pine bark, (M2) Paraserianthes falcataria bark, (M3) acacia bark, and (M4) fern. The second factor is the industrial growth concentration 20 ml/l (K0) and 10 ml/l (K1). The results showed that the acclimatization of Dendrobium sp orchid plantlets was successful as seen from the large growth in plantlet height and the emergence of new shoots. The treatment that produced the highest growth of Dendrobium sp orchid plantlets during the acclimatization period was fern media and the best rooting starter concentration was 20 ml/l. The combination that showed the highest growth in Dendrobium sp. orchid plantlets during the acclimatization period was fern media + 20 ml/rooting starter. Key words:   Dendrobium, tree bark, acacia bark, fern, rooting starter, Paraserianthes

Abstract

Chinese sprangletop (Leptochloa chinensis) reproduces sexually and vegetatively. This weed has a lot of seeds, is easy to grow, and adapts well to dry and wet land. Proper control is needed. Hoorahgrass extract can be used as an alternative to control weeds. Hoorahgrass (Fimbristylis miliacea) is a group of enigmatic weeds that contain allelochemical compounds. The aims of this research were to determine the effect of the source and concentration of hoorahgrass extract on the germination and growth of chinese sprangletop. This research carried out at the Greenhouse Integrated Field Laboratory, Faculty of Agriculture, University of Lampung from December 2022 to February 2023 using a Randomized Block Design (RAK) with 2 factors and 4 replications. The first factor was the extract component of hoorahgrass root (A1), shoot (A2) and mixture (A3), and the second factor was hoorahgrass with a concentration of 0% (B0) or (control), 2.5% (B1), 5% (B2 ), 7.5% (B3), 10% (B4). The data obtained were analyzed using analysis of variance, and first tested for homogeneity of variance using the Bartlett test, followed by the least significant difference test (LSD) at the 5% level. Based on the research results, hoorahgrass extract concentration of 5 to 10% was most effective in reducing seed germination rate, seed germination speed, chinese sprangletop root length and total dry weight. A concentration of 10% was most effective for reducing the height of chinese sprangletop. Keyword: Fimbrisylis, concentration, extract, bioherbicide, Leptochloa

Abstract

Cassava is a plant that is ranked third as a source of food in Indonesia. Apart from that, cassava is also needed in industries such as making tapioca flour. In 2021, cassava production in Lampung will be around 20-25 t/ha, this amount is still below the potential of superior cassava which reaches 35-40 t/ha. Cassava growth and production depend on the variety and land where it is cultivated. This research aims to determine the differences in growth and production of several early maturing cassava clones tested, namely Vamas-1, Vati-1, and UTK on Ultisol soil in the PT GGP research area. This research was carried out on the land of the PT GGP research division, Central Lampung, Lampung. This research was carried out from August 2022 to February 2023. The research method used was a Randomized Block Design (RAK) with one treatment, namely clones. There are 3 clones used, namely Vamas-1, Vati-1, and UTK. The experiment on each clone consisted of 3 replications with 36 plants in each replication, but 5 plants were selected from each replication as samples, so that 45 experimental units were obtained. The observation data was analyzed and then compared with the UJ5 clone data based on the Standard Deviation to determine the early maturation characteristics of the three clones. The results showed that clone treatment had no significant effect on growth and production. The number of fresh sweet potatoes at 24 weeks after planting (WAP) in terms of the quantity of clones Vamas-1, Vati-1, UTK, and UJ5 respectively was 7.3; 6.6; 6.3; and 7.3 fruit/plant with a fresh sweet potato weight of 2316,7; 2183,3; 2150,0; and 1433,3 g/plant. The starch content of Vamas-1, Vati-1, UTK, and UJ5 clones was 26,2%; 25,2%; 25,8%; and 23.2%..Keywords : early, Manihot esculenta, UTK, Vamas-1, Vati-1,

Abstract

Jagung (Zea mays L.) merupakan bahan pangan alternatif setelah padi. Untuk memenuhi permintaan akan bahan pangan jagung perlu dilakukan inovasi agar kebutuhan tersebut tercukupi, salah satunya dengan melakukan pengujian mengenai sistem tanam yang berbeda pada budidaya jagung. Sistem tanam yang berbeda diduga akan menghasilkan jumlah populasi tanaman akan berbeda, sehingga jumlah bobot panen jagung akan berbeda pula. Jagung membutuhkan banyak cahaya dan sumber daya lingkungan lainnya untuk tumbuh. Apabila pertumbuhan tanaman baik, maka proses laju pengisian biji yang diduga berpengaruh pada hasil produksi tanaman akan berlangsung optimal. Oleh karena itu, dilakukan penelitian ini yang bertujuan untuk mengetahui pengaruh sistem tanam yang berbeda terhadap proses laju pengisian biji pada tanaman jagung dan mengetahui sistem tanam yang paling optimal untuk pertumbuhan vegetatif, laju pengisian biji, dan produksi tanaman jagung. Penelitian dilakukan pada tanaman jagung varietas NK Sumo yang ditanam dengan 3 sistem berbeda yaitu legowo, konvensional, dan zig-zag. Variabel penelitian terdiri dari 3 bagian pengamatan yaitu laju pengisian biji, pertumbuhan vegetatif, dan variabel lingkungan. Hasil pengamatan laju pengisian biji menunjukkan hasil yang fluktuatif pada setiap waktu pengamatan. Meskipun sebagian besar hasil penelitian menunjukkan bahwa sistem tanam tidak mempengaruhi hasil pengamatan, namun terlihat bahwa sistem tanam zig-zag menghasilkan hasil paling tinggi diantara sistem tanam lainnya. Sistem tanam terbaik adalah pada perlakuan sistem tanam zigzag dengan bobot biji basah dan bobot biji kering seberat 216,58gram dan 56,25 gramsistem tanam ini diharapkan dapat meningkatkan produksi tanaman jagung per hektar.
