Abstract

Job's tears (Coix lacryma-jobi L.) is a carbohydrate source functional food crop that can be developed as a substitute for rice. This study aims to determine the best application frequency of phosphate (P) fertilizer and paclobutrazol for supporting the growth and yield of job's tears in both rainy and dry seasons. The research was conducted from November 2021 - November 2022 at the Ciparanje research station and Laboratory Centre Universitas Padjadjaran, Jatinangor, Sumedang. The experiment used a randomized block design (RBD) consisting of P fertilizer application frequency (once, twice, and thrice) and paclobutrazol application frequency (once, twice, and thrice) and three replications.. The best season was determined using the T-test. The results showed that there was no interaction between growth components and job's tears yield in both rainy and dry season planting. P fertilizer application had a significant effect on lateral branch per tiller in the rainy season and root-shoot ratio in the dry season. Paclobutrazol application had a significant effect on the number of tillers per plant and number of seeds per plant in the rainy season, and the lateral branch per tiller in the dry season. Planting in the rainy season had the best growth and yield components compared to the dry season.

Abstract

Spodoptera litura is a polyphagous pest and attack many families of cultivated plants, such as chili plants. Application of synthetic pesticides is still the mainstay for controlling this pest in the field. To support eco-friendly plant protection management, it is important to explore potential natural materials such as garlic extract. This research aims to determine the potential of garlic extract in controlling S. litura on chili plants, and to see its indirect effect on chili yield. The research was carried out in two sites, in the laboratory and the field. The experiment used a completely randomized design with 6 treatments and 4 replications. The concentrations of garlic extract, i.e., control (0%), 24%, 26%, 28%, 30%, and 32%. The results showed the application of garlic extract had a significant effect on the mortality of S. litura, the frequency of attacks, and the intensity of pest attacks in the field, and had an effect on the variable number of fruit and fruit weight of chili plants. The LC50 and LC90 values reached 19.66% and 29.97% in the laboratory, and 28.30% and 34.3%% in the field, respectively. The LT50 and LT90 values from the 32% garlic extract in the laboratory were respectively 3.37 and 7.23 days. The application of garlic extraction affected growth and yield, i.e. healthy leaves, number of fruits, and weight of fruits in chili. The garlic extract is potentially used as an organic pesticide to suppress the S.litura attacks while keeping the plant's growth and yield.

Abstract

Maize is a prospective food commodity that developed in Indonesia. The use of hybrid corn gives better yield than open-pollinated varieties. Spacing management in hybrid maize production can reduce competition between plants, so that the plant canopy and roots can grow optimally. This research aimed to compare the differences in the phenotypic performance of the agronomic characters of Padjadjaran maize hybrid, determine the dominant agronomic characteristics, and determine the correlation between the growth and yield characteristics at medium- and high-population densities. The experiment was carried out from December 2021 until May 2022 at Sanggar Penelitian, Latihan dan Pengembangan Pertanian (SPLPP) Universitas Padjadjaran, Arjasari, Bandung Regency. This experiment used Randomized Completely Block Design analysis with 20 treatments of Padjadjaran maize hybrids and 4 check varieties, all treatments were replicated 3 times in both population densities. Statistical analysis used multiple regression linear analysis and correlation test. The experimental results showed that the yield of 20 genotypes of Padjadjaran maize hybrids at medium population density was influenced by the ear length, number of seeds per row, and number of seed rows, while in the high population density, it was influenced by number of seed rows. Correlation analysis revealed a positive and significant relationship between the growth and yield components in medium population density. Meanwhile, the correlation at high population density between the components of growth and yield was not consistent.

Abstract

Robusta coffee production can be sucessed by using high-quality seedlings that have good growth performance. One of several keys to success in seedling production is the choosing best planting medium and providing exogenous growth regulators. These include using cocopeat planting media and giving coconut water. This research aims to determine whether using cocopeat planting media and providing coconut water can increase the growth of robusta coffee seedlings. The experiment used a randomized complete group design with six treatments and four replications; each experimental unit consisted of three robusta coffee seedlings. The six tested treatments were control (topsoil 100%); cocopeat 50% + topsoil 50%; cocopeat 100%; topsoil 100% + coconut water 200 mL; cocopeat 50% + topsoil 50% + coconut water 200 mL; and cocopeat 100% + coconut water 200 mL. This study indicated that cocopeat and coconut water could increase the growth of robusta coffee seedlings. The composition of cocopeat 100% and the combination of topsoil 50% + cocopeat 50% had an improvement effect on the growth of robusta coffee seedlings.

Abstract

This study assesses the impact of adding phosphate and boron in a mixed liquid fertilizer (MLF)  on the growth and yield of red chili plants cultivated in a subsoil environment. The experiment was conducted to comprehend how these nutrients affect the performance of red chili plants, particularly when cultivated in less ideal conditions such as subsoil, a remnant of excavation for brick production. The research was carried out at the Ciparanje Garden of the Faculty of Agriculture, Universitas Padjadjaran. The research design employed a Randomized Completely Block Design with the following treatments: A = Control (degraded soil without fertilizer), B = 0% MLF + 1 NPK, C = 0.25% MLF + 1 NPK, D = 0.50% MLF + 1 NPK, E = 0.75% MLF + 1 NPK, F = 1.00% MLF + 1 NPK, G = 0.5% MLF + 3/4 NPK, H = 0.5% MLF + 1/2 NPK, I = 0.5% MLF + 1/4 NPK, J = 0.5% MLF + 0 NPK, and K = 1 NPK in normal soil. The results revealed that the addition of phosphate and boron in MLF significantly influenced the growth and yield of red chili in subsoil conditions. The recommended MLF concentration was 0.75%, alongside the standard NPK dose. These findings provide crucial insights for the development of more efficient and sustainable agricultural practices, especially in challenging soil conditions like subsoil, where nutrient availability can be a determining factor for agricultural success.

Abstract

High-yielding varieties are the primary determinant of the success of increasing Indonesia's rice production. Plant breeding for new high-yielding varieties is possible through mutation induction and selecting desired traits. The effectiveness and efficiency of selection require comprehensive genetic parameters. This study aimed to study the genetic diversity, heritability, genetic advance, and relationship between yield components and yield in the M1 generation of mutant rice irradiated with gamma ray. This research used a factorial randomized complete block design, involving gamma irradiation doses of 100 Gy, 150 Gy, and 200 Gy, as the first factor; and the second factor was the rice genotype: UnsoedBDBP, UnsoedBDIU, UnsoedBPIU, UnsoedIUBD, and UnsoedIBP. Each treatment was repeated three times. Results showed that traits with broad genetic variation were tiller number plant-1, grain number panicle-1, and grain yield plant-1. High heritability and genetic advance values were found in plant height, grain number panicle-1, and yield plant-1, indicating that improvement in these traits can be achieved simply through selection methods. Panicle number plant-1 and filled grain percentage panicle-1 showed a unidirectional relationship and directly affected high values on yield plant-1. Therefore, these traits can be considered selection indicators for breeding high-yielding mutant rice.

Abstract

Potato seed production in the medium plain is necessary to avoid environmental damage and the limited area of potato seed production in the high plain. The effort to increase the production of G1 potato seeds on the medium plain is the evaluation of the biochar composition and concentration of paclobutrazol that can increase the production G1 potato seeds cv Medians in the medium plain of Jatinangor. The research was conducted from August to December 2022 at the Ciparanje Experimental Field. Jatinangor. Faculty of Agriculture. Universitas Padjadjaran. The experiment used a Factorial Randomized Block Design (RBD). The first factor was the biochar composition: m1 (100% compost), m2 (80% compost + 20% rice husk biochar), m3 (80% compost + 20% coconut shell biochar), and m4 (80% compost + 10% biochar husk rice + 10% coconut shell biochar). The second factor was the paclobutrazol concentration: p1 (without paclobutrazol), p2 (100 ppm paclobutrazol), and p3 (150 ppm paclobutrazol). The experimental results showed that there was no reaction effect of biochar compositions and paclobutrazol concentrations on the growth and yield of G1 potato seeds. The application of 80% compost + 20 % rice husk biochar gave significantly higher yields than treatment without biochar. The number of tubers was 6.29 knol per plant and the tuber weight was 66.80 g per plant. Application of 100 ppm paclobutrazol resulted in lower plant height, gave the number of tubers was 6.39 knol per plant, tuber weight per plant was 63.34 g higher than without paclobutrazol and produced more seed tubers with S class.

Abstract

Cymbopogon citratus, commonly known as lemongrass, is a perennial herb widely cultivated for its culinary, medicinal, and aromatic industries. This research investigates the morphological characterization and potential yield of different lemongrass lines. The study involved the collection of diverse lemongrass genotypes from various geographic regions in Indonesia. The research was conducted using a randomized block design with three replications. Morphological character observations encompass both quantitative and qualitative characters of plants. Morphological characteristics such as plant height, leaf length and width, stem diameter, and number of tillers were measured to assess the variations among the genotypes. The results revealed considerable variability in the morphological traits among the lemongrass. Plant height ranged from 102.28 to 158.96 cm, while stem length and diameter varied between 26.11 to 42.61 cm and 8.99 to 19.68 cm, respectively. The number of tillers per plant ranged from 7.59 to 49.41. Moreover, the essential oil content varied from 0.07% to 0.26% (v/w). According to correlation analysis, the stem's diameter and the leaf's width positively correlate with the essential oil content. As a result, we can continue to develop the Sukabumi local line to maximize biomass and essential oil yields.

Abstract

Adlay has great potential to be developed into an alternative food source in Indonesia because it contains carbohydrates and high fat. The aim was to effect of various doses of gamma-ray irradiation on growth,chlorophyll changes, and determination of lethal dose (LD50) three adlay genotypes in M1 generation. This study was conducted by using the experimental quantitative method without design. The material used consists of three adlay genotypes, including genotypes #28, #37, and #38. The seeds were treated with 0 Gy (control), 100 Gy, 200 Gy, 300 Gy, 400 Gy, and 500 Gy doses of gamma-ray irradiation by the Research Center for Radiation Process Technology, the National Research and Innovation Agency using Gamma Cell 220. The research was conducted at the Faculty of Agriculture Experimental Station, Universitas Padjadjaran, from December 2017 to July 2018. The  LD50 was calculated by the curve-fitting analysis program based on characters of survival percentage, height seedling, root length, and appearance of leaf chlorophyll change in the three adlay genotypes. The results showed that the treatment of gamma-ray irradiation gave a diverse response to characters of survival percentage, height seedling and rooting length of the three adlay genotypes. There were LD50 for each genotype, 346 Gy for genotype #28, 381 Gy for genotype #37, and 371 Gy for genotype #38. The optimum dose of gamma-ray irradiation for the three adlay genotypes was 300 Gy. The appearance of chlorophyll change leaf the three adlay genotypes caused by gamma ray irradiation treatments with doses of 100 - 500 Gy were able to produce variation in the spectrum and frequency of different chlorophyll change in the M1 generation, the irradiation treatment of 400 Gy dose was able to make the highest frequency of chlorophyll mutations with a total frequency of 46.28%. Meanwhile, the gamma-ray irradiation treatment of 300 Gy produced the broadest chlorophyll mutant spectrum with 6 types of chlorophyll change consisting of tigrina, striata, viridis, variegata, maculata and albina green.

Abstract

One of the crucial stages in the ramie plant (Boehmeria nivea L. Gaud) tissue culture is the acclimatization phase, which transitions between the in vitro and ex-vitro environments. Determining the appropriate age of plantlets and providing nutrients in the substrate play significant roles in the success of acclimatization. This research is conducted to determine the most suitable age of plantlets for acclimatization and assess the impact of providing nutrients through Trichoderma spp. application on the growth of ramie seedlings during the acclimatization phase. The experiment was conducted between January and March 2023 at the Screenhouse Bale Tatanen, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, Sumedang. The experimental design used was a Randomized Complete Block Design (RCBD) with two factors: plantlet age with three levels (4, 8, and 12 weeks old) and Trichoderma spp. fertilizer application with two levels (without and with Trichoderma) with 4 replications. The results showed that the 4-week-old plantlets exhibited the best height, root number, root length, and leaf number growth. Additionally, the application of Trichoderma spp. increased the stem diameter of the ramie seedlings during the acclimatization phase.
