Abstract

Applying environmentally friendly technology in melon cultivation aims to create sustainable agriculture. Nutrient and plant growth regulators management are simple to apply and have a relatively rapid effect on melon fruit production. Water footprint assessment in melon cultivation is crucial for ensuring sustainable agricultural practices and efficient water use. This study aimed to evaluate the electroconductivity of nutrient solutions and GA3 concentration in increasing fruit production and water footprint efficiency. This research was conducted from June to September 2022 at Tefa SGH Polije. This research used a completely randomized design with treatments that consisted of nine combinations of nutrient solution electrical conductivities (2.8, 3.2, and 3.6 mS cm-1) and GA3 concentrations (0, 60, and 120 mg L-1). Observation variables were fruit diameter, edible part thickness, fruit sweetness level, fruit weight, and water footprint. Data were analyzed using ANOVA and DMRT. Applying 2.8 mS cm-1 nutrient solution (NS) + 60 mg L-1 GA3 was the best treatment according to fruit diameter, edible part thickness, and fruit sweetness level. Although statistically, it had no significant effect, 2.8 mS cm-1 NS + 60 mg L-1 GA3 increased fruit weight by 18.75% and water footprint efficiency by 15.48% compared to control.

Abstract

Agronomic practices in Indonesia mostly still use ammonium as the primary source of nitrogen (N), whereas ammonium concentrations at certain levels can cause plant toxicity. The selection of the suitable N form (NH4+ and NO3-), especially by the fertigation method, is expected to increase the efficiency of N fertilization. This research aimed to obtain the appropriate source of NH4+ and NO3- to increase production and efficiency of fertilization in shallots. The experiment used a non-factorial randomized complete block design with four replications and six nitrogen treatments: without N, ammonium sources (urea, ZA), nitrate source (calcium nitrate), and combination of ammonium and nitrate (NPK Mutiara 16-16-16, calcium ammonium nitrate). The fertilizer doses contain N in equivalent levels, i.e., 167.9 kg N ha-1. The results showed that ZA increased the chlorophyll content of leaves and N content of plant tissue, while calcium nitrate increased the size and weight (fresh and dry) of bulb per plant. The highest recovery and agronomy efficiency was obtained in the ZA application, while the highest physiological efficiency and partial factor productivity were in calcium nitrate. Therefore, nitrate has the potential for shallot cultivation because it can increase production without accumulation in the bulbs.

Abstract

This study examined the effects of liquid organic fertilizer (LOF) derived from Moringa leaves and chicken eggshell fertilizer on basil (Ocimum sanctum L.) growth and yield. The experiment was conducted at Muhammadiyah University of Sidoarjo and arranged in a randomized block design with three replicates. The research incorporated two factors namely moringa leaf LOF at concentrations of 25, 50, and 75 mL L-1 and chicken eggshell powder at levels of 3, 6, and 9 g. The observation included plant height, leaf number, branches, root length, and fresh and dry weights. Data were analyzed using ANOVA, followed by Tukey’s Honestly Significant Difference (HSD) test at a 5% significance level. Results revealed a significant interaction between LOF and eggshell treatments. The 25 mL L-1 LOF plus 3 g of eggshell fertilizer produced the best results in all growth parameters. This suggests that these organic fertilizers can effectively enhance basil growth. The findings emphasize the potential of combining organic fertilizers at certain levels to optimize basil growth and yield. Keywords: basil growth; moringa extract; organic fertilizer

Abstract

Soil is a critical factor in determining fertilizer efficiency. Rubber tree requires a stable environment to achieve optimal growth and production. The research aimed to evaluate how fertilization and ethephon stimulation affected the nutrient dynamics of rubber in various clones. The Indonesian Rubber Research Institute experimental field in South Sumatra served as the site for the research. Three replications of the experiment were set up using a split-plot design with three factors. The rubber clones were the primary plot, with ethephon stimulation and fertilization rate as subplots. The rubber clones used in this research, namely GT 1, BPM 24, PB 260, and IRR 112, were planted in 2011 (8 years) with a 6 x 3 m planting spacing on the existing rubber plantation. Several rates of fertilization were used in the experiment: 50% recommended rate (50 RR), 100% recommended rate (100 RR), 150% recommended rate (150 RR), and control (no fertilizer). During the observation period, ethephon stimulation was administered at a rate of S/2 d3 ET2.5% 6/y (half spiral cut, tapped downward every 3 days with ethephon stimulation of 2.5% active ingredient and application of 1 g per tree on groove, six times per year at monthly intervals) every two months. Observation parameters were soil nutrient analysis (soil pH, cation exchange capacity (CEC), C-Organic, total nitrogen, available phosphorus, and exchangeable bases (K, Ca, Mg), and leaf nutrient analysis (N, P, K). Results showed that soil properties were improved by fertilization after a year of treatment. Organic-C, CEC, total nitrogen, available phosphorus, and exchangeable cation increased across rubber clones. Tissue analysis in leaves and nutrient content also showed significant differences between fertilization and stimulation treatments in all clones. Further research is required on which chemical fertilizers with biological fertilizers can induce low nutrient availability in poor soil conditions.

Abstract

Rice (Oryza sativa L.) variety 'Inpari 24 Gabusan' offers high nutritional value and a short growth cycle that is ideal for further development. This study aimed to assess the effect of silicon priming on the growth and photosynthetic pigments of rice 'Inpari 24 Gabusan' during the vegetative stage under drought conditions. A completely randomized design (CRD) was used with two factors: sodium metasilicate (Na₂SiO₃) concentrations (0 mM, 20 mM, 40 mM, and 60 mM) and field water capacity (100, 75, and 50%). Germination parameters (percentage and rate of germination, and seed vigor index) and vegetative parameters (plant height, leaf number, root length, biomass) were measured. Leaf chlorophyll and carotenoid content were also assessed. Results showed that silicon priming increased the germination rate from 57.17% at 0 mM to 63.83% at 60 mM. Seed vigor index significantly improved at 60 mM. However, sodium metasilicate concentration had no significant effect on the percentage of germination. Priming at 40 mM and 60 mM significantly enhanced growth and chlorophyll content, particularly at 100% and 75% field capacity. Under 50% field capacity, growth improvements were more limited due to water deficit. Higher sodium metasilicate concentrations also enhanced chlorophyll content, improved photosynthetic efficiency and drought tolerance. Keywords: carotenoid; chlorophyll; field capacity; germination; sodium metasilicate

Abstract

Nepenthes reinwardtiana Miq. is an endemic species distributed in Sumatra and Kalimantan and classified as least concern due to the lack of recent research data on its abundance and distribution. Excessive exploitation, deforestation, the long time required to reach the generative phase, and the dioecious flowering type have caused a population decline. Plant propagation through cuttings can support conservation activities. The success of cuttings is determined by the concentration of plant growth regulators (PGR), making studies on PGR concentration important. This research aimed to determine the best indole-3-butyric acid (IBA) concentration for inducing roots and shoots in N. reinwardtiana. The study was conducted from February to October 2023. The research was arranged based on a completely randomized design with IBA concentration treatments consisting of 5 levels: 0, 5, 10, 15, and 20 mg L-1. The results showed that there was no significant effect of IBA on all variables. However, 5 mg L-1 IBA gave the best responses on shoot height increase (10.9 cm), leaf number increase (5.0 leaves), and root length (8.7 cm). These findings suggest that the growth of N. reinwardtiana cuttings may rely heavily on endogenous auxin levels, reducing the observable effects of exogenous IBA application. The non-significant results highlight the potential of this species to thrive without external auxin under certain conditions, which could simplify propagation protocols.

Abstract

Intercropping of sweet corn and caisim is an effort to improve land efficiency. The study aimed to determine the land use optimization of intercropping between sweet corn and caisim from different plant densities and planting times. Research was carried out from May to July 2024, in Bocek Village, Malang, East Java. The study used a randomized complete block design with a single factor consisting of 7 treatments, i.e., monoculture sweet corn, and sweet corn + caisim (1 and 2 rows) planted 7 days before, at the same time, and 7 days after planting corn. Results showed that all intercropping treatments resulted in R/C ratio and LER values > 1, with the highest values observed of sweet corn + caisim of 1 row planting at the same time. The R/C ratio was 1.22 and the LER was 1.35, indicating that land use was optimized without causing a decline in growth or production for either crop. Keywords: cropping system, LER, number of rows, R/C ratio, Zea mays

Abstract

Cassava is an important crop for carbohydrate production, primarily propagated through stem cuttings. Auxin has been proven for decades to be an effective material for increasing the rooting of cuttings. The combination of NAA and IBA is more effective than a single auxin and synergizes in promoting root growth. This study aimed to evaluate the growth and yield of cassava clones to different auxin concentrations of NAA+IBA mixture. The research used a randomized complete block design arranged in a factorial with 9 (3x3) treatments repeated 3 times. The first factor was the type of cassava clone, consisting of K1 = Garuda, K2 = Katsesart, and K3 = Roti, while the second factor was the concentration of NAA + IBA (1:1), namely A0 (0 ppm), A1 (1,000 ppm), and A2 (2,000 ppm). The results showed that clones responded differently to auxin concentration. Increasing the auxin concentration from 1,000 ppm to 2,000 ppm did not increase growth and yield, irrespective of clones. The application NAA + IBA (1:1) significantly increased fresh leaf weight, plant height, fresh stem weight, total number of roots, and number of storage roots as compared to the control at 8 months after planting (MAP). At 8 MAP, the Kasetsart clone produced higher growth and yield than Garuda and Roti clones, as indicated by the average plant height, total number of roots, and number of storage roots.

Abstract

Seed storage is an important aspect of plant breeding. Aged seeds tend to lose their viability during storage, reducing their ability to grow. One effort to increase the viability of seed germination that has been stored for a long period is to provide priming treatment to the seeds before planting. The purpose of this study was to evaluate the effect of garlic oil emulsion on the germination of aged melon seed that has been stored for more than five years. The study was conducted using a factorial completely randomized design (CRD). The first factor consisted of two melon seed lines that had been stored for more than five years, namely Ougan makuwauri (V1) and Ginsen makuwauri (V2), and the second factor was the priming treatment consisting of P0 = Aquadest, P1 = 0.125% garlic oil emulsion, P2 = 0.25% garlic oil emulsion, and P3 = 0.5% garlic oil emulsion, each treatment was repeated three times with a soaking time of 20 hours. There is an interaction between the line and priming treatment that significantly affects the variable of cotyledon opening on the fifth day and hypocotyl length. Meanwhile, the single priming treatment has a significant effect on the observation variable of cotyledon opening on the third day and has a very significant effect on the variable of root length of germinated melon seeds.

Abstract

Plant resistance to drought stress could be improved by seed priming using natural plant growth regulators, such as coconut water. This research aimed examine the physiological characteristics, root development, and yield responses of waxy corn following different seed priming treatmens using coconut water and to determine to the optimal coconut water concentration for seed priming under each drought condition. The research was conducted at Banguntapan Sub-district and Laboratory of the Faculty of Agriculture, Universitas Gadjah Mada, Yogyakarta - Indonesia, in July-October 2023. The research used a split-plot design with a main plot of watering intervals and a subplot of coconut water concentration with three replications. The main plot consisted of three levels: watering every day, once every three days, and once every six days. The subplot consisted of four levels of coconut water concentrations, i.e., 0, 33, 67, and 100%. The results indicated that seed priming with 100% coconut water increased corn yield. The increased yield could be attributed to the different photosynthetic rates and total seed weight under both well-watered and drought-stress conditions. Keywords: coconut water; drought stress; root improvement
