Abstract

Edamame, a legume consumed fresh as a vegetable, is highly nutritious, particularly protein-rich, and holds significant economic value. However, its cultivation faces challenges, especially on dry land, due to water scarcity and limited nutrient availability, particularly potassium (K). This study, which investigated the impact of potassium fertilization rate on edamame cultivation, underscores the need for further research. The study utilized a single factor, potassium fertilization rate, arranged in a completely randomized block design. Potassium rates consist of 0% X, 50% X, 100% X, 150% X, and 200% X, where X represents the recommended potassium fertilization rate according to the dry soil test device (DSTD) guidelines. Each treatment was replicated five times. Data were analyzed using ANOVA at a 5% significance level, and any significant effects were further examined using orthogonal polynomial and regression analysis. The results indicated that potassium fertilizer rates did not significantly affect edamame height, pod weight per plot, and marketable yield. However, the study identified the optimal potassium fertilizer rate, which was between 83%X and 119%X, equivalent to 83–119 kg.ha⁻¹ of KCl (50–72 kg.ha⁻¹ of K₂O). This range positively increased total branch yield, productive branches, number of flowers, pod weight per plant, number of pods per plant, and plant dry weight, producing a quadratic response pattern. The study recommends further research to optimize potassium fertilizer doses based on DSTD recommendations, particularly at a low K nutrient status, to maximize marketable yields through fertigation.

Abstract

Vertical space optimization through a multi-canopy system can potentially increase rice production. This research aims to evaluate the agronomic performance, light interception, and production of rice plants cultivated with a multi-canopy system. This research was conducted at the Sawah Baru Experimental Farm, IPB University. Rice varieties used two common height plants (“Inpari 30” and “Inpari 32”) and the taller plants (“IPB 9G”). This research consisting of nine treatment combinations of cultivation system: mono-variety (“Inpari 30”, “Inpari 32”, and “IPB 9G”), combination of two varieties in one hill multi-canopy (“Inpari 30”-“IPB 9G” and “Inpari 32”-“IPB 9G”), inter-variety one-insertion multi-canopy (“Inpari 30”-“IPB 9G” and “Inpari 32”-“IPB 9G”), and inter-variety two-insertion multi-canopy (“Inpari 30”-“IPB 9G” and “Inpari 32”-“IPB 9G”). The results showed morphological and physiological performance as good in a multi-canopy system (inter-variety one insertion) on the variables of the plant height, number of panicles per clump, panicle length, number of grains per hill, weight of grains per hill, photosynthetic rate and land equivalent ratio (LER). The percentage of light interception in the multi-canopy system decreased by 19.13-61.54%. The inter-variety one-insertion multi-canopy with the “Inpari 30”-“IPB 9G” combination increases yield potential by 10.18%, and the “Inpari 32”-“IPB 9G” combination increases by 13.81% compared to the mono-variety. The combination of the “Inpari 30”- “IPB 9G” and “Inpari 32”-“IPB 9G” variety in an inter-variety one-insertion multi-canopy system produces an LER value of 1.75 and 1.64; this shows that the inter-variety one insertion multi-canopy system is promising to increase rice production.

Abstract

Jack bean or koro pedang is a potential source as a soybean substitute for food and feed. In production, the plant is also useful in crop rotation and intercropping to support sustainable agriculture systems. However, jack bean production in Indonesia is still challenging. One of the obstacles in the production is the flowers and pods dropping, which reduces yield markedly. This study aimed to evaluate the source and timing of additional potassium fertilizer on the generative phase and yield of jack bean. The experimental design used a randomized complete block design with two factors, i.e., the source of potassium fertilizer as the first factor consisting of five levels: no fertilizer application, base fertilizer, base fertilizer + goat manure, base fertilizer + rice husk ash, and base fertilizer + KCl. The second factor was fertilization time, i.e., at 46 and 121 days after planting. The treatment of the potassium fertilizer source and fertilization timing affected several generative characters, but did not have much effect on productivity. Future studies should identify other potassium fertilizer sources to find the optimal dose to support plants in the generative phase. Keywords: additional potassium; flower drop; koro pedang; pod formation

Abstract

This study aims to identify the morphological characteristics of 17 taro genotypes. The research involved the inventory and morphological identification of taro genotypes in Bogor, West Java Province, and Ponorogo, East Java Province. The morphological description of taro followed the guidelines in the IPGRI descriptor book. Analysis of variance (ANOVA) was used to examine quantitative data. Using the 22-0 version of SPSS Software, Duncan’s multiple range test was employed at a 5% significance level to determine whether the variables observed had a significant effect. A cladogram was created to evaluate the degree of similarity between the taro genotypes based on the collected data. Fourteen genotypes of Colacasia have been identified, consisting of 7 Eddoe types: Satoimo, Ozikawa, Siromi, Jepang Ungu, Dempel, and Dempel Ungu, 7 Dasheen types including Bentul Ungu, Ketan, Pratama, California, Sutra, Pari, and Bentul, while 3 Xanthosoma including Talas hitam, Talas HIjau, and Talas Kuning. The results showed that the highest association coefficient values were found in Pratama with California, Bentul Ungu with Ketan, and Ozikawa with Siromi. The genotypic variance coefficients were high for characters associated with taro's growth and yield, including corm weight, cormel diameter, cormel weight, and plant span.

Abstract

Cowpea (Vigna unguiculata L. Walp), known as tolo beans in Indonesia, is a nutrient-dense legume consumed as young pods, dry seeds, or livestock feed. Despite its nutritional value and agronomic potential, cowpea productivity in Indonesia remains low. This study aimed to evaluate the effect of poultry manure and NPK fertilizers on flowering, pod formation, and seed filling of cowpea. The experiment was conducted from July to October 2024 at the Sawah Baru Experimental Field, IPB, using a randomized complete block design. Treatments included poultry manure at 0, 10, 20, and 30 tons ha-1 and NPK (16-16-16) at 0, 100, 200, and 300 kg ha-1. Results showed that poultry manure at 10-30 tons ha-1 and NPK above 100 kg ha-1 significantly increased the productive nodes at the ninth week after planting. Both fertilizers enhanced plant growth and yield. The highest average seed yield was obtained at 30 tons ha-1 poultry manure (3.64 tons grain ha-1) and 300 kg ha-1 NPK (3.38 tons  grain ha-1), highlighting the benefit of integrating organic and inorganic fertilization to boost cowpea productivity. Keywords: cowpea; chicken manure; NPK fertilizer; kacang tolo

Abstract

Intercropping between sweet corn (Zea mays L. var. saccharata Sturt) and cowpea (Vigna unguiculata L. Walp) can improve land productivity, but requires optimization of row orientation and cowpea row number. This study evaluated the effects of row orientation and cowpea row number on the growth, yield, and economic performance of sweet corn–cowpea intercropping. The experiment was conducted from June to September 2024 at the IPB experimental field in Sawah Baru, Bogor, Indonesia. A split-plot design with four replications was employed. The main plots consisted of two row orientations (North–South and East–West), while the sub-plots included maize monoculture, intercropping with one row, and two rows of cowpea. A significant interaction between row orientation and cowpea row number was observed on maize height, leaf number, and stem diameter at two weeks after planting. Although row orientation did not significantly affect maize and cowpea performance, the East–West orientation increased cowpea yield by 14.6% and reduced maize yield by 5.3% compared to the North–South orientation. The East–West orientation combined with one cowpea row produced the highest land equivalent ratio (LER = 1.93) and benefit–cost ratio (R/C = 1.45). Keywords: LER, R/C ratio, aggressivity, competitive ratio

Abstract

The study aimed to evaluate the effects of irrigation line number and plant density on the growth and yield of curly red chili pepper (Capsicum annuum L.) cv. Tangguh. The study was conducted from August 2023 to January 2024 at the Cikarawang Experimental Station of IPB University (6°32’56” S; 106°43’54” E; 240 m above sea level) on Ultisol characterized by severely low phosphorus (1.1 ppm) and high potassium content (66 ppm). A split-plot design within a randomized complete block design was employed, with irrigation line number (single or double drip lines per bed) as the main plot and four planting densities (26,666, 53,322, 80,000, and 106,666 plants.ha-1) as subplots. Each treatment was replicated three times, resulting in 24 plots (each 1.5 m × 10 m). Fertilizers applied included Urea (45% N), SP-36 (36% P2O5 ), cattle manure, dolomite, biofertilizers (Trichoderma spp.), and PGPR. Irrigation and fertigation were managed using the Nutrigads automatic drip system. The data collected included plant growth, yield components, nutrient use efficiency, water use efficiency, and partial factor productivity for nitrogen (N) and phosphorus (P). The results showed that the irrigation line number had no significant effect on individual plant growth parameters. However, using double lines significantly increased total fruit yield per bed and hectare, indicating its contribution to overall productivity. Conversely, the double line system reduced water use efficiency (WUE = 2.07 kg.mm-1) compared to the single line system (WUE = 3.64 kg.mm-1; P<0.0001). Higher planting densities (up to 106,666 plants.ha-1) enhanced total yield by promoting vertical growth but reduced individual plant performance, and had a positive effect on WUE, NUE, and PUE.

Abstract

A well-structured root system is essential to ensure optimal plant growth and yield. Two experiments were conducted to determine the effects of plant growth promoting rhizobacteria (PGPR) on the root system of okra plant. These experiments were arranged with a completely randomized design. The first experiment was conducted in the growth chamber with 8 different bacterial isolates consisting of Methylobacterium sp., Bacillus sp., Bacillus methylotrophicus, Flavobacterium tirrenicum, Providencia stuartii, Azotobacter vinelandii, Methylocystis parvus and PGPR consortium. The second experiment was conducted in the greenhouse and examined the effects of four poultry manure rates, i.e. 0, 6, 12 and 18 ton ha-1, or equivalent to 0, 75, 150 and 225% of recommended rates and how these are altered with the presence or absence of PGPR. The results of the experiments showed that, PGPR significantly improved root architecture; the number and length of lateral roots was increased by 242.86% and 777.79% respectively, as well as the dry weight of the roots and shoots of okra plant by 236.36% and 333.33%, respectively. Moreover applying 150% (12 t.ha-1) of the recommended rate of poultry manure enriched with PGPR was found to be most effective in terms of improving the growth and root attributes of okra plants.
