Abstract

One of the efforts that can be done is to increase the national corn productivity by developing prolific composite corn varieties. This is done because prolific corn is a type of corn with a tendency to produce two or more cobs, so that it can increase the value of corn production. The purpose of this study was to obtain prolific corn candidates (two cobs) with high yield and uniformity. This research was conducted using the mass selection method. Mass selection is done by selecting plants that have the desired character, namely prolific corn (cob two). The observed variables were the diversity in the F4 population, the percentage of prolific maize, and the comparison of the yield components of prolific maize with non-prolific maize. This study succeeded in obtaining 50% prolific corn on the cob and has wide diversity criteria. Of the 561 prolific corn plants, there are 91 corn plants that are classified as productive prolific. Prolific maize has a higher yield component than non-Prolific maize. Seed weight with cobs on productive prolific corn reached 318 g and seed weight reached 268 g.

Abstract

Citronella grass (Cymbopogon nardus L) is one of the essential oil-producing plants from the Gramineae group. This research was conducted in the Greenhouse of the Faculty of Agriculture, Andalas University, Padang from August 2017 until January 2018. This study aimed to determine the effect of Acaulospora sp and different water treatments on the growth of citronella grass in ultisol. A completely randomized design with two factors was used. The first factor was treatment with or without Acaulospora sp. The second factor was the water supply which consisted of three treatments (saturated, three quarters saturated and half saturated soil). Every treatment was repeated three times. Data were analyzed by analysis of variance using the F-test at the 5% level. Significant differences were further tested using Duncan’s New Multiple Range Test also at the 5% level. Treatment with Acaulospora sp and 75% saturated soil gave the best number of leaves and canopy to root ratio. Treatment with Acaulospora sp showed the best results for the number of tillers, stem diameter, root dry weight, and dry weight of the citronella plants. Acaulospora spp promote the growth of citronella grass.

Abstract

Citronella is a biopharmaceutical plant that has the main content of citronella and geraniol as raw materials in the manufacture of essential oils (citronella oil) which have high economic value. The production of citronella increases every year although the amount is still small when compared to the production of other biopharmaceutical plants. So it is necessary to increase the productivity of citronella plants with the use of the right dose of fertilizer. This study aims to determine the effect of potassium fertilizer dose and Compost Dose of Empty Palm Oil Bunches (EFB) on the growth of citronella (Cymbopogon nardus L.). The research was started in February-June 2022 at Balai Pengkajian Teknologi Pertanian (BPTP) Banten, Ciruas District, Serang Regency, Banten and the Laboratory of the Department of Agroecotechnology, Faculty of Agriculture, Sultan Ageng Tirtayasa University. This study used a Randomized Block Design (RBD) method which consisted of two factors, namely potassium fertilizer dose and Compost Dose of Empty Palm Oil Bunches (EFB). The first factor has 4 levels, 0 kg/ha potassium (K0), 15 kg/ha (K1), 30 kg/ha (K2) and 45 kg/ha (K3). The second factor has 4 levels, 0 tons/ha (T0), 20 tons/ha (T1), 30 tons/ha (T2) and 40 tons/ha (T3). There were 16 treatment combinations with 3 replications so 48 experimental units were obtained. Each experimental unit contained 2 polybags where each polybag contained 2 plants, so the total plants in the study were 192 plants. The results showed that the dose of potassium fertilizer 30 kg/ha gave the best results on plant height parameters at the age of 3, 4, 5, 6 WAP, the dose of potassium fertilizer 15 kg/ha gave the best results on the number of leaves aged 1 WAP. Dosage of 40 tons/ha of TKKS compost gave the best results on the number of leaves aged 5 and 6 WAP. There was no interaction between the dose of potassium fertilizer and the dose of TKKS compost on all parameters at the age of 1-12 WAP

Abstract

Aren palm (Arenga pinnata Merr) belongs to the palm tribe. The problem that is often encountered in aren palm plants is the low productivity of aren palm plants, this is allegedly because the seeds used are not superior seeds and cultivation techniques that are not yet appropriate. The low production of plants is thought to be due to the low knowledge of the community on the use of superior aren palm planting materials, where the cultivated aren palm is not considered superior properties, including the diversity of aren palm species that grow wildly is still high in one forest land, unclear identity of seeds used by farmers. Exploration is the first step in finding germplasm of aren palm plants that have the expected traits through breeding programs so that it is expected to be one of the solutions for the development of aren palm plants. This research will be conducted from May to October 2023 in community-owned aren palm plantations in 50 cities. The purpose of this research is to characterize the morphology of Aren plants in District 50 Kota and to see the level of diversity of aren palm plants in the area. The research method was survey method, with purposive sampling. The data collection technique is to observe the morphological parts of the plant in each sample. The data obtained were analyzed descriptively, while for the analysis of similarity the calculation of the NTSYS Ver 2.02 program was used. The results of the study obtained 4 clusters of palm plants from 3 villages namely Nagari Sungai Kamuyang, Sikabu-kabu and Mungo. Researchers obtained 15 samples of aren palm plants characterized by 19 characters, namely 10 characters have wide variability and 9 characters have narrow variability with a level of diversity ranging from 14% - 47%.
