Abstract

Tomato (Lycopersicum esculentum Mill) is a horticultural commodity classified as a vegetable plant and has high economic value in the local and international markets. This research was conducted to determine the effect of applying oil palm frond compost on the growth and yield of tomato plants and to determine the best dosage of oil palm frond compost to increase the yield and growth of tomato plants. This research was conducted at the Screen House of the Faculty of Agriculture, University of Pasir Pengaraian, from July 2022 to October 2022. The design used in this study was a Completely Randomized Design (CRD) with 5 treatments, namely P0 = Without adding oil palm. frond compost, P1 = 25 g/polybag of palm frond compost, P2 = 50 g/polybag of palm frond compost, P3 = 75 g/polybag of palm frond compost, P4 = 100 g/polybag of palm frond compost. The results showed that the application of various doses of palm frond compost significantly affected the parameters of the number of fruits per tomato plant. Still, they had no significant effect on the parameters of plant height, number of leaves, and flowering time. The P4 treatment, namely applying palm frond compost at a dose of 100 g/polybag, tended to produce the best observation parameter: the number of fruits per plant. In contrast, the plant height parameter tended to be better with applying palm fronds. frond compost.

Abstract

Carica pubescens needs a climate and edapic environment similar to that of its native Dieng plains in order to thrive. Due to these circumstances, measures must be taken to facilitate its diffusion. Another option is transplanting to regions with nearly identical edaphic and climatic characteristics. The growth of C. pubescens planted in monoculture and intercropping, as well as the degree of crop competition in intercropping and the effectiveness of the land used, the slopes of Mount Lawu are advised for transplant. The study's planting treatments were as follows: (1) C. pubescens monoculture; (2) Sweet Potato Monoculture; (3) C. pubescens and Sweet Potato Combination; (4) Leek Monoculture; and (5) C. pubescens and Scallions Combination. The study was set up in a randomized block design (RBD) with five replications. The ANOVA analysis of the growth characteristics, which comprised planting height, leaf area, and the number of leaves, was then proceeded using Duncan's test at the 5% level. Utilize the competition ratio (CR) formula to determine plant competition and the land equivalent ratio (LER) formula to determine productivity. The number of leaves parameter in the C. pubescens and sweet potato combination indicated a significant difference in the results. When grown alongside sweet potatoes, C. pubescens tends to be less competitive, with plant height values of 0.86: 1.27, 0.83: 1.72 for leaves, and 0.94: 1.10 for leaf area. The intercropping system is more lucrative with a value of plant height: 1.84, number of leaves: 1.89, and leaf area: 1.99 compared to plant height: 2, number of leaves: 2, and leaf area: 2, 25.

Abstract

Oil palm seedlings can be grown using either organic or inorganic fertilization; however, organic fertilization is more environmentally beneficial. This study seeks to determine the impact of organic fertilizer type and dosage on the growth of oil palm seedlings in the main nursery. This investigation employed a two-factor factorial experimental method arranged in a completely randomized design (CRD). The form of organic fertilizer consists of three levels: banana stems, water hyacinth, and manure. The second factor is the organic fertilizer dosage, which consists of three levels: 100g, 250g, and 300g. Five repetitions yielded nine treatment combinations and one control treatment (plants without organic fertilizer ) from these treatments. Observations included plant height, leaf count, stem diameter, fresh crown weight, dried shoot weight, root length, fresh root weight, dry root weight, and root volume. The results demonstrated a significant interaction between the type and dosage of organic fertilizer on the parameters of plant height, root length, shoot fresh weight, root fresh weight, and root volume. The combination that yields the greatest results is 300 grams of manure. Applying organic fertilizer in varying quantities results in superior plant growth compared to the control (without organic fertilizer ).

Abstract

Biochar is a soil enhancer because it contains macronutrients and has a high water-holding capacity. Research on the application of biochar and resistance of oil palm seedlings to drought stress was conducted to determine the dosing effect of oil palm shell biochar and watering intervals on the growth of pre-nursery oil palm seedlings under drought stress. The research was conducted in Sialang Godang Village, Bandar Petalangan District, Pelalawan District, Riau Province. The study was conducted in April 2021 – July 2021. The research used a completely randomized design (CRD) with two factors. The first factor was using biochar doses of 5 levels, namely 0 g, 50 g, 100 g, 150 g, and 200 g. The second factor was the watering interval which consisted of 3 groups, i.e.,, watering once a day, every two days, and every three days. Observational data were analyzed using an analysis of variance, and if there was a significant difference, it was continued with the Duncan Multiple Range Test at the 5% level. The results showed that giving biochar at a dose of 200 grams of oil palm shells and watering once every two days significantly increased the fresh weight of roots while providing biochar at a dose of 50 grams of biochar/polybag and watering once every three days significantly increased the dry weight of roots. Watering once every three days significantly increased the number of secondary and tertiary roots, while treatment without biochar and 50 gram/polybag biochar significantly increased the width of stomatal openings. There was a positive correlation between soil moisture content and the number of stomata (r = 0.26), the width of the opening of the stomata, and the dry weight of the roots (r = 0.25).

Abstract

Green bean is a food ingredient that is extensively consumed by the general public and is categorized as having a high frequency of use. This study seeks to determine the effect of organic goat manure on the growth and yield of green beans (Vigna radiata L). It will also examine the impact of plant spacing and the interaction between the two factors. This investigation utilized a factorial randomized block design (RBD) with two regimens and three replications. The first variable was the amount of goat manure organic fertilizer applied to each plot: 0 kg/plot, 2 kg/plot, 4 kg/plot, and 6 kg/plot. The second factor is the variation of the different spacing sizes, which are 20 x 40 cm, 25 x 40 cm, 30 x 40 cm, and 35 x 40 cm. In this study, the following parameters were observed: plant height, number of productive branches, number of pods per sample, number of pods per plot, pod production per sample, pod production per plot, and 100 seed weight per sample. The study's results indicated that the application of goat manure organic fertilizer, the assessment of different plant spacings, and the interaction between the two treatments had no significant effect on any of the parameters. Include plant height, number of productive branches, number of pods per sample, number of pods per plot, pod production per sample, pod production per plot, and 100 seed weight per sample.

Abstract

This study seeks to determine the impact of palm oil wastewater, the number of biopore holes, and their interaction on oil palm plant growth and Dystrudepts soil physical properties. This study was carried out between December 2019 and April 2019. This research was conducted using a 3x3 factorial experiment with a Randomized Block Design; each treatment was replicated three times, and each experimental unit contained three plants for 81 experimental plants. The first variable was the dosage of palm oil effluent, which consisted of 7.5 liter/plant/2 weeks, 10 liters/plant/2 weeks, and 12.5 liters/plant/2 weeks. The second factor had three levels: two biopore holes/plants, four biopore holes/plants, and six biopore holes/plants. Analysis of variance (ANOVA) was applied to the data. If the treatment is markedly different, a second test is conducted using the 5% level of the Honest Significant Difference (BNJ) test. (1) Palm oil mill effluent at a concentration of 7.5 liters/plant increased the total pore space. The effluent from a palm oil mill at a rate of 12.5 liters per plant decreases BD and PD while increasing final plant height, midrib length, leaf length, and chlorophyll content. (2) Adding two biopores per plant increased plant height, midrib length, and leaf width. The presence of four biopores per plant decreased BD and PD and increased leaf length and chlorophyll content. Six openings per plant biopores have an effect on increasing the total pore space, and (3) The interaction between LCPKS doses of 12.5 liters/plant and the number of biopores of 6 holes/plant decreases BD and increases total pore space, plant height, frond length, leaf length, and leaf breadth.

This study aims to determine the effect of interaction and the main effect of Calcite and Kiserite treatment on improving the chemical properties of Inceptisol media, increasing the yield and mineral content of Moringa leaves. The research was conducted at Karen Nisrina Agro, Kampar Regency, with a 4x3x3 factorial Completely Randomized Design. The first factor is Calcite with 3 dose levels, 0.0 tons ha-1., 2.11 tons ha-1 and 4.22 tons ha-1. The second factor is Kiserit with 4 levels, 0.0 tons ha-1., 0.35 tons ha-1.,0.45 tons ha-1, and 0.55 tons ha-1. Observation parameters: chemical properties of the media (pH, Ca and Mg), leaf yield and stover, and leaf mineral content (Ca and Mg). Observational data were analyzed using analysis of variance at 5% significance level, followed by Duncan's multiple distance test at 5% significance level. On the chemical properties of the soil, the interaction of giving Calcite and Kiserite occurred at pH and Ca media. Calcite increases the pH and Ca media. Kieserite increases Mg and decreases Ca media. The application of Calcite and Kiserite significantly increased the yield of leaves and stover, but there was no interaction between them. For leaf mineral content, the interaction of giving Calcite and Kiserite was found in the Ca content of the leaves. Calcite and Kiserite application had no significant effect on the Ca and Mg levels of the leaves.

Abstract

Peat as agricultural land has various obstacles, one of the problems is the decrease in groundwater level. This can have an impact on the availability of nutrients in the soil. Therefore, water management is an absolute necessity for agricultural activities on peatlands. Another effort that can be made to increase the fertility of peatlands as agricultural land is to use organic mulch. This study aims to analyze the effect of peat water level and application of organic mulch on the chemical properties of peat soil planted with corn. This research was conducted in Air Terbit Village, Riau Province and the Soil Laboratory, Faculty of Agriculture, University of Riau, from February to July 2021. This research used a factorial complete randomized design (CRD) method consisting of 2 factors. The first factor was the various heights of the groundwater level which consisted of 3 levels (30 cm, 40 cm and 50 cm), while the second factor was various types of organic mulch (without mulch, mulch of empty oil palm bunches, mulch of rice straw and mulch of corn stover). The results showed that the GWL 30 cm treatment and rice straw mulch increased the pH, Ca and Mg values ​​better than the other treatments, the N element also increased at GWL 30 cm. In general, the two treatment factors also increased the values ​​of P, CEC and Na in some experimental units. C-organic and K values ​​decreased after the treatment compared to the criteria of the soil before treatment.
