Tomato quality is influenced by fertilization and matutity level. This study aimed to determine the best dosage of amino acid-enriched leaf fertilizer (Amiboost) and to determine the best nutritional content at several ripeness levels of ‘Optima’ tomatoes. Amiboost is an inorganic foliar fertilizer that is rich in amino acids that can be easily absorbed by plants. The experiment used a factorial (RCBD) with 3 repetitions. The ‘Optima’ tomatoes were grown at Wonosobo and fertilized with 4 levels of Amiboost fertilizer consisting of 0, 1, 2, 4 L ha-1 amino acid fertilizer, and 2 L ha-1 comparison fertilizer (standard fertilizer). The research was conducted at the Horticulture Sub-Laboratory, UGM at 27 °C with a relative humidity of 75%. The tomato quality observed was CO2 concentrations, visual quality rating (VQR), fruit weight percentage, fruit hardness, fruit color, total soluble solids, total titrated acid, vitamin C, carotenoids, lycopene, and flavonoids. The observation was terminated when the score of VQR reached 1 as the shelf life of tomatoes. The best dose of amino acid-enriched leaf fertilizer (Amiboost) is 2 L ha-1 for the lightness (*L) of fruit color, ascorbic acid, and lycopene. The maturity stage of fruit significantly affected vitamin C, flavonoids, total soluble solids, carotenoids, and lycopene. Keywords: Aminoalkanoic; shelf life; leaf fertilizer; tomato quality

Salah satu langkah peningkatan hasil tanaman adalah pemberian pupuk hayati, contohnya Jamur Mikoriza Arbuskular (JMA) dan kompos lumpur pengolahan limbah susu. Mikoriza telah dikenal dapat meningkatkan hasil dan pertumbuhan berbagai tanaman, sedangkan literatur mengenai kompos lumpur pengolahan limbah susudi Indonesia masih terbatas. Penelitian ini bertujuan untuk mengetahui tanggapan terung (Solanum melongena L.) terhadap pemberian mikoriza dan kompos lumpur pengolahan limbah susu dan mengetahui pola hubungan antara dosis kompos lumpur pengolahan limbah susudengan hasil terung yang dikombinasikan dengan pemberian mikoriza. Penanaman terung dilakukan pada bulan November 2021 hingga Maret 2022 menggunakan Rancangan Acak Lengkap (RAL) dua faktor, faktor pertama yaitu mikoriza (tanpa mikoriza dan dengan mikoriza) dan faktor kedua kompos lumpur pengolahan limbah susu (0 g/polibag, 25 g/polibag, 50 g/polibag, dan 75 g/polibag). Pemberian mikoriza dan kompos lumpur pengolahan limbah susu menyebabkan peningkatan pertumbuhan dan hasil terung (Solanum melongena L.) khususnya panjang akar dan umur berbunga. Pola hubungan yang terbentuk antara dosis kompos lumpur pengolahan limbah susu dengan hasil terung mengikuti persamaan garis kuadratik dan tidak tergantung faktor pemberian mikoriza. Dosis optimal kompos lumpur pengolahan limbah susu untuk bobot buah segar terbaik yaitu 75,5g/polibag.

Weeds cause significant yield loss in many agriculture crops; thus, management practices are urgently needed to alleviate losses while conserving environmental and human health. This study aimed to evaluate the allelopathic potential of Wedelia leaf and flower extracts on the germination and early growth stage of three plant species. The research was conducted using a completely randomized design experiment with two factors and four replicates. The first factor was extract sources: leaves (S1) and flowers (S2). The second factor was the concentration: control (C0) and extract concentrations of 1% (C1), 5% (C5), and 10% (C10). The extract was tested on three different plant species: soybean (Glycine max), nutsedge (Cyperus rotundus), and billygoat weed (Ageratum conyzoides). Fifty seeds of three different plants were germinated separately in Petri dishes and treated using Wedelia extracts. The allelochemicals in Wedelia leaf and flower extracts inhibited germination and induced abnormal sprouting. Wedelia leaf extract showed the most pronounced inhibitory effects and highest inhibition levels across all measured parameters. Moreover, a clear concentration-response relationship was observed, where increased extract concentration increased the degree of inhibition. These findings contribute to the development of bioherbicides and can help reduce the use of synthetic herbicides for more sustainable agriculture. Keywords: Ageratum conyzoides, bioherbicide, Cyperus rotundus, Glycine max, weed control
