Abstract

Indonesia is one of the largest cassava producing countries in the world with various types and advantages. Waxy clones have a high starch content and therefore they can be used as a food substitute for rice. Tissue culture through somatic embryogenesis is an effective technique for rapid and mass seedling propagation. This research aimed to determine the effect of the type and concentration of auxin 2,4-D or picloram and the addition of NAA on the formation of Waxy cassava clone somatic embryos. This research used a completely randomized design (CRD) which was arranged in a non-factorial. Auxin 2,4-D and picloram were used at four concentration levels: 0 mg.l-1, 8 mg.l-1, 10 mg.l-1, 12 mg.l-1, and additional NAA treatment of 6 mg.l-1 each. Results showed that MS + 6 mg.l-1 NAA treatment produced the highest callus weight. Meanwhile, the percentage of embryonic callus and number of embryo was higher in the treatment of MS + picloram 12 mg.l-1 and NAA 6 mg.l-1 (19,05 ± 5,82 %) and MS + 8 mg.l-1 2,4-D + 6 mg.l-1 NAA (11,11 ± 3,17 %) with 5,48 ± 3,56 and 4,93 ± 1,95 embryos, respectively. Thus, auxin picloram 12 mg.l-1 + NAA 6 mg.l-1 were the most effective in inducing the formation of somatic embryos on waxy cassava clone.

Abstract

This research aims to determine the effect of concentrations of Paklobutrazol and SP-36 fertilizer on the growth of peanut plants (Arachis hypogaea L.). This research was carried out in October 2023 – January 2024 at the Dsn Baban Barat Land in Blega Bangkalan, East Java. This research is a factorial experiment which was prepared using a Completely Randomized Design (CRD) with 3 replications. The first factor is the provision of Paklobutrazol ZPT and the second factor is using SP-36 fertilizer Factor I: Paclobutrazol (P) concentration which consists of 4 levels: P0 = 0 ppm, P1 = 100 ppm, P2 = 200 ppm, P3 = 300 ppm and Fakor II = SP-36 fertilizer dose consisting of 3 levels: S0 = 150 kg/ha, S1 = 200 kg/ha, S2 = 250 kg/ha. The parameters observed were plant height, number of leaves (strands), age at flower emergence, number of pods planted, number of filled and empty pods, weight of pods planted, weight of seeds planted. The research results showed that the Paklobutrazol concentration treatment gave a positive response to the specified parameters, including plant height, number of leaves (strands), age at flower emergence, number of pods planted, number of filled and empty pods, weight of pods planted, weight of seeds planted. The highest average yield of pod weight per plant was in the P1 concentration treatment, namely 100 ppm (33.78 gr). The Paklobutrazol concentration treatment also produced a very significant effect on seed weight per plant. The highest was in the P1 concentration treatment, namely 100 ppm 28.50 gr. The SP-36 fertilizer dose treatment had a significant effect on the number of pods, the weight of the pods planted and the weight of the seeds planted. However, the parameters of plant height, number of leaves (strands), age at flower emergence, number of filled and empty pods, had no real influence. The results of the combined data analysis from both gave a positive response to observations of the number of pods, the weight of the pods planted and the weight of the seeds planted.

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

Spatifilum is classified as a shade plant that can survive in environments with minimal sunlight or shading Spatifilum plants are known to absorb toxins or clean indoor air from pollutants such as benzene and formaldehyde. Efforts to stimulate flowering and the emergence of spatifilum seedlings include using a growth regulator in the form of benzyladenine (BA). The aim of this research was to determine the difference in the effect of residual BA with and without BA on the flowering of spatifilum plants in the second period. Data collection was carried out in August – November 2022 at the Horticulture Greenhouse, Faculty of Agriculture, University of Lampung. This research used a Complete Randomized Block Design (RAKL) with a single treatment. The treatment consisted of 5 BA concentration treatments, namely 0 ppm, 20 ppm two applications, 20 ppm four applications, 40 ppm two applications, and 40 ppm four applications with four repetitions. The data from this research were analyzed using the barlet test and the additivity test was carried out using the Tukey test. Then the data was analyzed using variance (Anara) and orthogonal contrast tests. The results of the research showed that there were significant differences in the variables of increasing the number of seedlings and increasing the number of flowers. BA concentration of 20 ppm was significantly able to increase the number of offspring compared to a concentration of 40 ppm, meanwhile, a concentration of 40 ppm with a frequency of giving 2x significantly increased the number of flowers compared to a frequency of giving 4x

Abstract

Optimal rice production is very important to meet national food needs amid a decline in harvest area and production yields. This study aims to analyze the influence of rice planting methods and genotype on the growth and yield of rice plants (Oryza sativa L.). The research was conducted on the Lampung State Polytechnic Experimental Land using a factorial Group Random Design (RAK) with two factors: the planting method (legowo row 2:1, planting distance 25x25 cm, and transplanter 2:1) and rice genotype (PTP 01, Inpari 24, Jeliteng, and Pandan Wangi) each method was repeated 3 times. The results of the study show that the interaction of planting methods and rice genotype has a significant effect on the growth and yield of rice plants. The combination of the 2:1 transplanter planting method and the Inpari 24 genotype gave the best results in terms of plant height (101.33 cm), number of saplings (29.33), number of productive saplings (25.00), and yield per hectare (12.48 tons/ha). The 2:1 transplanter planting method and the Inpari 24 genotype can be recommended as the best combination in increasing rice productivity.

Abstract

Philodendron xanadu is one of the leaf ornamental plants that much liked by society. Apart from being an ornament, P. xanadu also functions as an absorbent of toxic compounds contained inside the room. The potential development of P. xanadu is quite promising because the plant is widely used for decorating rooms and garden-forming elements.  The growth rate of P. xanadu which derived from the separation of saplings is very slow, where the plant height is barely increased, but the addition number of saplings is very rapid / numerous. These conditions are unfavorable when used as an ornamental plant because the beauty of the plant is not optimally expressed. To overcome this, it is necessary to conduct research on the use of gibberellic acid (GA3) and naphthalmylene acetic acid (NAA) to spur the plant growth.  The purpose of this study was to determine the influence of the use of GA3 and (NAA) to the growth of P. xanadu. The study was arranged factorial (2 factors) with a group randomized environment design. As the first factor is three levels of GA3 (0, 50, and 100 mg.l-1), and the second factor is 3 levels of NAA (0, 50, and 100 mg.l-1). Each experimental treatment was repeated 4 times. The results showed that the given of NAA and GA3 concentrations of 0, 50, and 100 mg.l-1 had no effect on the growth (leaf length) and the number of saplings P. xanadu. Keywords: GA3, NAA, Philodendron xanadu

Abstract

Shallot is an important commodity, but their productivity in Indonesia is still low. TSS can be used because of its higher production, longer shelf life, more resistance to disease pathogens, cheaper procurement and distribution costs, guaranteed seed quality, and high productivity potential, but has a small shape so it is difficult to plant so seed coating technology is needed. Seed pellets are coatings of seeds to change the shape, size and weight of seeds. This study aims to determine the effect of pelleting techniques on shallot seeds. This research was conducted with one treatment factor, namely without pelleting, soil + CMC, soil + CMC + Mycorrhizae, soil + CMC + Trichoderma, soil + CMC + Dolomite, soil + CMC + humic acid, soil + AG, soil + AG+ Mycorrhizae, soil +AG+Trichoderma, soil+AG+Dolomite, soil+AG+Humic acid. Each treatment was carried out with 3 replications so that 33 experimental units were obtained, with one experimental unit in the form of a planting media tray with 25 seeds each. The results of the study explained that the pelleting technique had no effect on germination, root length, coleoptile length, wet safe weight, dry safe weight, seed weight and had a significant effect on the emergence of plumules with the best treatment obtained in the soil. CMC + humic acid and seed pellet weight. stated that seed pellets can change the weight, size and shape of seeds so as to facilitate planting. The conclusion of this study is that shallot seed pelleting can be applied to shallot cultivation because it does not inhibit the growth and development of shallots and can facilitate the planting of shallot seeds. Key words:  Shallot, seed, pelleting, TSS
