Mangosteen (GarciniamangostanaL.) knows as one of the most delicious fruit in the word, itâ€™s call as â€œQueen of fruitsâ€. The problems in mangosteen culture are low productivity and low fruit quality due to less developed technical culture, especially on fertilizer. There is a little information available on mangosteen fertilizer recommendation standards based on scientific experiment.Phosphor fertilizer increased growth especially in the generative stage of mangosteen. Phosphor increases the number of flowers and fruits set. It also decreases the number of flowers and fruits drop, with a linear response. It indicates mangosteen trees absorb phosphor to increase the vegetative growth and support production. Fertilizers increase phosphor concentrations in leaf tissues. Leaf tissues analyses showed the status of phosphor status, This status has a correlation to the yield. The higher the nutrients concentration in the leaf tissues, the higher the mangosteens yield in the next harvest

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.

Background: Cherry tomatoes are one of the horticultural crops that can potentially be cultivated with household farming systems to fulfil the food supply. The increasing global temperature caused by climate change makes growing cherry tomato plants challenging. Besides that, nitrogen efficiency in the cultivating process of cherry tomato plants is crucial. This study aims to know the growth responses of cherry tomato plants in temperature and nitrogen doses. Methods: A completely randomized design with two factors was used for this study. The first factor was the temperature (normal and high-temperature treatment). The second factor was the nitrogen doses (55 ppm, 110 ppm, and 165 ppm). Observations of growth characteristics included plant height, leaf number, stem diameter, root length, root fresh weight, root dry weight, root-shoot ratio, shoot fresh weight, shoot dry weight, plant canopy diameter, and growth index. Findings: On day 8, normal temperature was the best result for enhancing the number of leaves. Besides that, nitrogen 55 ppm was the most effective for increasing the number of leaves. Next, at day 20, normal temperature was the best result for increasing leaf number, stem diameter, root length, root fresh weight, root dry weight, shoot fresh weight, shoot dry weight, and growth index. Then, nitrogen 110 ppm + normal temperature was the most significant response of root-shoot ratio. Conclusion: Normal temperature and minimal nitrogen doses were the most effective conditions for enhancing the growth of cherry tomato plants. Novelty/Originality of this article: This study examines cherry tomato plants' remarkable ability to grow at normal temperature and minimum nitrogen level.

Katuk (Sauropus androgynus) is a species valued for its nutritional and medicinal properties, as well as its potential applications in food, herbal medicine, livestock feed, and cosmetics. This study aimed to evaluate the morphological diversity and secondary metabolite profiles of four katuk accessions. Two analyses were conducted: (1) morphological characterization using cluster analysis and (2) qualitative and quantitative assessment of secondary metabolites. Cluster analysis revealed that all accessions showed high similarity with the “Paris”, an accession widely grown in West Java, Indonesia (similarity coefficient = 1.00), and moderate similarity with accessions “K1”, “K2”, “K4”, “Bastar”, and “Zanzibar” (distance coefficient = 0.68). Metabolite profiling indicated variations in compound abundance among accessions. “Ciaruteun Ilir 1” exhibited the highest vitamin E content; “Ciaruteun Ilir 2” had the highest fatty acid and phenolic content; “Pager Jangkung 1” accumulated the most flavonoids, while “Pager Jangkung 2” contained the most terpenoids and carboxylic acids. The leaves of katuk accessions in this study contains 14-17% squalene; this is an important finding for the pharmaceutical and health industries.

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.

Katuk merupakan sayuran indigenous tahunan yang banyak ditanam di berbagai agroekologi. Tanaman yang mengalami cekaman air memerlukan tambahan unsur hara dalam proses pertumbuhan, yaitu dengan cara pemupukan. Penelitian bertujuan mengetahui pengaruh cekaman air dan interval pemupukan daun terhadap pertumbuhan tanaman katuk. Penelitian dilakukan pada Agustus hingga November tahun 2021 di rumah kaca Kebun Percobaan Leuwikopo, IPB Dramaga, Bogor. Rancangan percobaan yang digunakan adalah rancangan split-plot dalam rancangan kelompok lengkap teracak (RKLT) yang terdiri atas dua faktor yaitu interval pemupukan daun sebagai petak utama dan cekaman air sebagai anak petak. Interval pemupukan daun terdiri dari tiga taraf, yaitu P0 (tanpa pemupukan), P1 (2 minggu sekali), dan P2 (4 minggu sekali). Faktor cekaman air terdiri dari empat taraf, yaitu C1 (40% kapasitas lapang (KL)), C2 (60% KL), C3 (80% KL), dan C4 (100% KL). Penelitian dilakukan dengan tiga ulangan dengan 12 kombinasi perlakuan, sehingga terdapat 36 satuan percobaan. Hasil menunjukkan bahwa cekaman air tidak mempengaruhi pertumbuhan tanaman katuk hingga umur 6 Minggu Setelah Transplan (MST). Pertumbuhan tanaman yang mendapatkan pengurangan pemberian air hingga 40% kapasistas lapang masih setara dengan tanaman dengan pemberian air kapasitas lapang (100%). Interval pemupukan daun 2 dan 4 minggu sekali meningkatkan jumlah cabang, jumlah daun, dan bobot panen daun katuk. Interaksi antara cekaman air dan pemupukan daun tidak berpengaruh terhadap pertumbuhan tanaman katuk. Kata kunci: bobot panen, interval pemupukan, sayuran indigenous, stres air
